Recently, there was clearly a live Spiderman & Villain fighting appearing on the street of Abu Dhabi. Why is it called Spiderman & Villains fighting? It is because the fighting happened via a flight, and something man fell down coming from a height of 40 meters, which scene is able to be viewed in such scientific movies as the Spiderman.

My business is very sad at this accident, which should happen to be avoided. Although both engineer as well as the crane operator are experts in most aspect, they neglect to have the least gumption of safety, because if you are within the tower crane, it is best to pay all-around your behaviors in case a good trivial mistake would give rise disastrous result. You are unable to be distracted inside crane, not to say fighting. Are you aware that crane operators, they need to always maintain focused and keep calm. Any bad and unrest mood ought to be dispelled before they board the crane.

In line with Khaleej Times Online, the entire story goes such as this. The victim, a 39-year-old Arab assistant engineer got enraged if the 33-year-old Asian crane operator called him a�?crazya�? over some work-related dispute. Within a fit of anger, he climbed the tower crane tower to discipline the operator. An altercation developed between two plus self defence the crane operator hit him with the iron bar. The assistant engineer fell down at a 40-metre-high crane and died.

This bloody tragedy must give you a good lesson to everyone drivers, especially crane operators and alarm them again of life safety. Beyond the basic rules stated earlier, there are another safety tips that crane operators should keep in your mind. For instance, the used tower cranes operators should keep consistent with the hand signals from his guide strictly. This involved information, including tips and hand signals, has become covered inside my two previous posts. If you’re interested, you’ll be able to return to the homepage my weblog, finding and reading them.

Tout ensemble, I have to remind all crane operators: Don’t play fire along with your cranes ; remain happy and safe everyday, the best idea approach to love both yourself and your loved ones.

 There are lots of different industries that rely upon lifting equipment to move heavy items. These include construction, transport, mining, steel, gas and oil. Companies that leave industrial equipment must be able to keep informed effectively with industry developments and with safety requirements. This can be a heavily regulated industry making specialist equipment, one in which quality counts for much. Each industry making use of heavy lifting gear has different would need to fulfil:

Coal and oil:

The coal and oil industries make use of Lifting equipment for construction and repair of oil rigs and gas plants. Heavy equipment, such as drilling equipment, is needed over these industries and also this needs to be put in place and maintained. Products are also employed for evacuation and safety reasons �C e.g., for lifeboats on offshore oil rigs.

Construction:

The building industry is on the list of key users of lifting equipment in industry. Walk past any building site, and there’s likely to end up a minumum of one crane currently in use for lifting. Along with cranes, other styles of apparatus like hoists and winches works extremely well. Generally, one can use them for lifting heavy construction materials into place during building, and sometimes for removing old or damaged ones. They could also be used in publishing scaffolding.

Transport:

The transport industry, and particularly the rail industry, uses Lifting equipment frequently for construction and maintenance. Railway tracks and ballast are heavy, and replacing or maintaining them requires proper lifting gear. Moving new trains onto tracks or old ones off them also necessitates the use of heavy duty equipment built to take care of large and heavy items.

Mining:

Like the gas and oil industries, the mining industry relies on lifting equipments to maneuver heavy equipment. Furthermore , it needs equipment to move the extracted coal (or other material) once many experts have mined. The exact uses of lifting gear in mining depend slightly on the form of mining �C e.g., open cast mining uses different strategies of extraction to deep mining and will use different equipment therefore.

Steel

The steel industry uses portable lifting equipments that will put pick-up and move heavy steel sheets and other items. A steel mill might make an array of steel items �C including huge sheets and girders for the construction industry. Needed equipment that could deal with these varied demands, and often use magnetic equipment.

 A luffing jib tower crane has lost its jib on a site in Ealing, London these evening, no one have been injured inside incident and then we are not aware of whether it’s associated with the strong gusty winds currently in the area.

The crane, owned by rental company LTC �C London Tower Cranes �C was working on the Dickens Yard site in Ealing Broadway, becoming developed by St George. The operator was treated for shock, but was otherwise unhurt.
A spokesman for St George acknowledged the incident had occurred, but stated that it wasn’t possible to comment at this stage for the possible cause.

The high quality crane and jib which appears to have experienced a sheared jib bolt, are said to be stable, even though they will likely be monitored overnight for virtually every further movement or risk.

 Road and civil engineering lifting equipment is now through incredible advancements in recent decades causing all of them happen to be directed towards improving speed, and quality. That may be that today��s machines pave a lot more road in less time, and they also do a better job of computer. This turn has additionally helped to create costs down once the costs are obviously factored for inflation.

Lasers are also put to use in guidance systems; systems which allow a device operator to follow along a beam to get a far more accurate course setting. Actually, lasers are now used in many general construction construction machinery with handheld (point and shoot) automatic laser measuring devices now being being among the most discussed among them.

Laser technology has taken huge improvements in how everything is completed in paving today. Lasers are offer every type of uses, including far more accurate measuring and guidance systems and it also all commences with the surveyors. The truth is, road surveyors are now using a laser to plot an absolutely straight line for setting grade, height and depth with the planned layout.

One huge increase in road and civil engineering construction construction machinery is compact asphalt batch plants that may be dismantled and moved down a highway as being the work progresses. Now this are a wide change from the way things were carried out years just before their development. When hot asphalt must be basically trucked in a single load at any given time.

At these road asphalt micro-plants, gravel is in a silo and combined with a mixer oven together with hot molten tar, because load is necessary. Then after the load has become sufficiently heated and mixed it��s dumped out chute to some waiting transport truck. Now the savings out there micro-plants derives from several directions including needing fewer trucks and drivers for the job, together with certainly lower materials costs.

It��s all done at once with this particular machine that distributes shapes, forms, and compresses evenly since it trundles down its assigned path. Now earlier versions of the machine, that��s crafted from high grader steel to stand up under its heavy workload, would have to be towed behind a big truck. Today though, modern versions are self propelled, and operated by the driver who sits in a very comfortable air conditioned cab.

The primary paving tasks are done by the important machine which the dump trucks deliver their loads of fresh mixed hot road asphalt to. It��s very sensibly often called an asphalt paver and it also replaces that old method of doing things, that has been basically spreading the material manually with shovels the way it spilled out the back of your tipper lorry. It��s all done automatically now.

Now even though the fresh road bed that��s spelled out through the asphalt paver is compacted, still it requires further compaction which is finished with several sizes of compacting machines. As an illustration, there are large rolling compactors that essentially roll on two weighted heavy steel barrels that are for wide open areas. You can also find smaller units which have been used for more closes in work around things like driveways, and drainage grates.

 The level set in the two legs of the bridge constitute a bridge crane gantry shape. This crane orbit on the ground , mainly used in open storage yard , shipyards , power plants , ports and railway stations and other places for cargo handling and installation. the Gantry crane hoisting mechanism , trolley traveling mechanism and bridge structures , bridge crane with basically the same . As the span, crane operating agencies were driven mostly used way to prevent the crane operation and increase the resistance generated skew even accidents. Gantry crane lifting trolley running on the bridge , some lifting trolley is a jib crane . Legs on both sides of the bridge are generally rigid legs ; during span of more than 30 meters, often rigid leg side , while the other side of the flexible legs connected by ball joints and bridge , and the door frame to become statically determinate system under external loads due to avoid lateral thrust caused additional stress can also be compensated bridge vertical temperature deformation. gantry cranes wind area, in order to prevent strong wind in the fall or tip line , equipped with anemometers and interlock with the operation of institutions crane rail clamp . Free ends of the bridge can be a cantilever ; may have one end or both ends of the cantilever arm to extend the operating range. Semi- used gantry cranes bridge legs at one end and the other end without legs , running directly on the high bench . Gantry cranes are divided into four types .

1 shipbuilding gantry cranes : for berth assembled hull , standing with two lifting car: There are two main hook of a run on the track on the bridge flange ; another has a primary and a secondary hook hook in running on the bottom flange of the rail bridge to flip and lifting large hull section . Weight is generally from 100 to 1500 tons ; span of 185 meters ; lifting speed of 2 to 15 m / min , and 0.1 to 0.5 m / min jog speed.

2 ordinary gantry cranes : This crane ( see pictures ) is the most versatile and can carry a variety of items and bulk materials , from the weight of 100 tons , a span of 4 to 35 meters. Grab the ordinary with gantry cranes working a higher level.

Gantry Cranes

3 Station gantry cranes : for lifting and hoisting the main gate , but also for the installation. Lifting capacity of 80 to 500 tons , the span is small, 8 to 16 meters ; low lifting speed of 1 to 5 m / min. Although this is not always the crane lifting, but once the work is very heavy use , it should be appropriate to increase the working level .

4 container gantry cranes : for the container terminal . After the trailer carrying the container wharf bridge transported from the ship to unload the container yard or rear , stacking up by the container used gantry cranes or transported directly loading can accelerate bridge or other crane carrying containers turnover . Can be stacked high 3 to 4 layers , wide and 6 rows of container yard , usually with tire type , it also has a rail -style . Compared with the container Gantry crane container straddle carrier , its height and span both sides of the door frame are larger . In order to meet the transport needs of ports , the higher the level of this crane work . Lifting speed of 8 to 10 m / min ; span based on the number of containers needed across the row to determine a maximum of about 60 meters . Corresponding to 20 feet , 30 feet from the weight of 40 -foot-long containers were approximately 20 tons , 25 tons and 30 tons .

 A tower crane jib snapped at the site of a 20-storey tower block in Croydon during severe storms over the weekend.

The London Fire Brigade said: ��The high rise building on Wellesley Road is under construction and the crane��s jib is believed to have snapped.

��A safety cordon was put in place and specialist crane engineers were called to secure the structure. There were no reports of any injuries.��

The unfinished tower block was formerly known as the IYLO building.

Work restarted on the tower last year after construction stopped in June 2011 when the previous investors ran into financial diffulties.

The site has now been renamed the Island and is being developed by Regency Homes.

The collapsed crane is a Jost model.

 Latest fast-erecting crane 65K from Liebherr production line will likely be first introduced at Intermat 2012 exhibition in Paris. It truly is based on the successful notion of the Liebherr 81K, that have combined determining trends in performance, reliability, safety, and design.

The carrying capacity of a single,400 kg at 40m places Lebherr 65K in the top in its category, and possesses a maximum load capacity of 4500 kg..

 With the gradual construction of the tall , short durations direction, the demolition of tower cranes in construction of increasingly frequent assembly and disassembly has become a very important part of the work . Author based on years of work experience in the demolition of the tower crane should pay attention to several issues with colleagues questionable, in order to increase the total .

1 staff organization
Tower crane assembly and disassembly is an important and dangerous and stressful jobs dimensional works must attach great importance to the ideological arguments , from the organization is fully guaranteed . In addition to construction management and with the necessary professional and technical personnel , all construction workers should be subject to professional education, with corresponding types of safety knowledge , skills certificates. Construction Tower crane assembly and disassembly performed by professional construction team .

2 Select the installation site
Under the premise of the tower model has been selected , the installation site selection should be good at the following : �� the first installation to complete the overall project construction , to avoid secondary displacement ; �� avoid dead ends appear on the construction plane ; �� fixed attachment points easy selection and installation ; �� facilitate the completion of construction tower crane dismantling and transportation ; avoid �� construction space within its sub- structures , such as high-voltage grid ; �� need help with the installation according to the construction lifting equipment and other building components .

3 to discuss the demolition of construction equipment and machinery ready
3.1 Problems in
Tower crane migration typically involves the removal , transportation, installation and other aspects of the equipment and machinery must be carefully organizational arrangements necessary to ensure safety, but also to improve the efficiency and economic benefits. It should be noted : �� all lifting equipment is installed both to avoid overkill , and not permitted to use the overload capacity ; �� Tower crane transport equipment should be based on the quality of the various components , dimensions and other arrangements to try to avoid long , high, wide, overweight transportation ; �� maximize the use of edge removal, side loading transport , construction and installation methods edges to avoid secondary unlucky or not occupied the construction site to the heart ; �� site should be willing to work with or ambulance , aerial work must be equipped with necessary communication tools enabling safe operation , normal construction .
3.2 Prepare an inventory of equipment and spare parts
Construction of missing pieces , small pieces , etc. affect the progress of common occurrences , strengthen management, inspection and maintenance to ensure the construction schedule to deal with the above components ; equipment dedicated small parts , spare parts ; special , Bolt , mother, pad ; various specifications and the number of connecting pins, shafts ; special tools and equipment are equipped with a detachable ; partially damaged structure deformation dressing tools ; rope cards, rope ring.
3.3 lifting spreader rigging choice
General construction tower crane assembly and disassembly should be equipped with white rope or nylon rope , a variety of rope sets, cables, a certain number of # 8 wire and special tools. These appliances insults have sufficient allowable tension and the safety factor , different performance spreaders , rigging subject to appropriate use and disposal standards .

4 tower cranes foundation
Before installing the tower cranes must ensure a correct , well- based tower cranes foundation for fixed pedestal and two kinds of walking tracks , should pay attention to the following questions.
1 ) rail -based construction design requirements should ensure that the thickness of gravel roadbed width , spacing sleepers , rails model , rail joints, connecting rod, bumper , grounding and other technical requirements .
2 ) There shall be no tower cranes foundation under the culvert , dugouts , etc., should be provided with the necessary drainage facilities .
3 ) is the basis of the carrying capacity of the ground -based foundation , shall take the necessary measures to ensure that the ground carrying capacity 10-20t/m2. 3:7 compaction or lime can be used compaction methods such as construction . Avoid peer backfill with garbage do not deal directly with the base or the track .
4 ) fixed base construction design requirements should ensure that ministries size bolts embedded in particular must ensure that basic requirements of the center to the size of buildings , construction and attached to the installation .

5 ) should be installed tower , underground construction should ensure that the Tower crane at a distance from the edge of the pit floor .
Installation and dismantling of tower cranes 5
5.1 preparation before disassembly
Dismantle the used tower cranes is the central part of the construction of a great danger , we must be fully prepared before construction : �� technician or construction plan should be prepared according to the specific characteristics of construction design and construction of the installation manual , and a safe technical tests content. Before construction program must be communicated to all construction workers jobs , avoid going through the motions ; �� construction program to deal with major and difficult parts of the assembly and disassembly method of calculation and discussed in detail , with clear construction methods , choosing the right equipment, sling, lifting point , tying methods.
5.2 assembly and disassembly operations
Banner Engineering process must be unity of thought, unity of command, use the relevant safety procedures and construction. It should be noted : �� legs lifting equipment used in construction should be playing on firm ground , pad or square wooden planks necessary ; �� oblique hanging, hanging side , select the appropriate lift crane hanging position and auxiliary traction and other measures ; �� 2m aerial above must have security protection, rain and wind is more than five stops operating , construction midway tower must be installed in a safe state in case the storm ; �� lifting operations when the boom shall never be turned , and let someone protection ; �� assembly and disassembly must be strictly required by the order of the construction program , the installation frontier boom should add weight , unassembled not be lifting heavy weight . Demolition should be removed after the demolition counterweight boom ; �� check the connections tower cranes parts are complete , reliable and effective , and its lifting , rigging and so on whether safety.
Select hanging point 5.3
Select and mounting method construction crane Tower crane assembly and disassembly point is to ensure that an important part of safe construction should pay attention to several issues . �� components lifting point should be fixed position or special lifting points can be configured by your own design if necessary. Side hanging, hanging diagonally should ensure its rational inclination. Lifting point should be selected on the structure of the inner sleeve when the jacket structure , to avoid internal and external isolation, as TQ60/80 tower spire . �� boom and the balance arm and other parts should be guaranteed after the lifting and horizontal direction, the longer the boom mounted in the longitudinal direction as far as possible non-horizontal lifting method , the hinged end of the arm that is arranged above the head end of the arm , the hinge after mounting the boom to the horizontal position , as FO/23B 50m tower boom and the like. �� tower cranes boom is articulated around two parts into one , when you try to dismantle lifting point should be selected so that the arm level, the smaller the force by the location of the temporary connection string . �� disassembly is the reverse operation to install, more dangerous, should be strictly in accordance with the instructions on the disassembly sequence construction plan their operations , must reverse the order . �� try not to use hooks Jia Shengsuo lifting heavy objects .
Testing and Debugging 6 tower cranes
Testing and commissioning of the installation and construction of the Tower crane is the last step , the last pass before the tower surface is also used, so testing and debugging is also a very important job. It should be noted : �� on various parts of the machine must be complete and detailed inspection , identify problems and timely solutions ; �� commissioning tests should also do the various parts of the maintenance work ; �� Tower crane working bodies should operate normally , all security guards should be complete effective ; �� machine inspection records should do to prepare for commissioning and acceptance of the tower cranes .
7 management system developed
Installation and removal of the Tower crane is a highly systematic management of construction projects, my unit has developed a relatively complete system of speed management measures based on years of experience and lessons learned from the organization , the system is fully guaranteed. Develop more detailed rules on the management of all aspects of construction , such as the Tower crane foundation acceptance and technical files , installation and removal mission statement , installation and removal safety technical tests , track inspection records , construction records disassembly , assembly and disassembly is complete inspection records , parts inventory records, technical tests , such as the use of safe , proven effective .

 Liebherr has taken selling point of the 2012 ��Intermat�� to provide in my ballet shoes the brand new 380 EC-B 16 Litronic flat-top used cranes. This now extends the series upwards, which thus far has contained fifteen models well-spaced between 50 and 285 mt, with a 380 mt unit. The new ��flagship�� provides a maximum radius of 75 m, and can lift up to three,400 kg at the end of the jib. The 380 EC-B can be obtained optionally in 12 t or 16 t format.

With all the IC tower system, free-standing heights under hook of close on 70 m is possible. And when the specific situation calls for increased heights under hook, the 380 EC-B can optionally be installed on the 355 HC / 500 HC tower system, then reaches a free-standing height under hook of almost 85 m. And, naturally, the newest 380 EC-B will also support the usage of existing modules on the market tower systems.

The revolutionary 380 EC-B 16 Litronic also provides a lot of flexibility, in this it could be fitted with the IC or HC tower system. The 256 IC and 355 IC towers from Liebherr are seen as an their small tower cross-chapters of just one.9 m x 1.9 m, driving them to wonderfully-fitted to erection in lift shafts. The climbing function of the IC tower system allows it to climb both within the building along with it.

The visually striking appearance on the new 380 EC-B is marked specifically from the impressive crane superstructure. One characteristic feature could be the four-chord counter-jib. The very compact quality crane superstructure, with a maximum radius of 75 m, might be loaded onto only five trucks. Particular attention seemed to be paid within the design to making certain the size of each individual part meet the requirements of container transport, a significant advantage on the subject of loading onto ships. All the islands EC-B head, such as IC slewing ring support as well as the 75 m jib, can be accommodated in 40-foot containers without any trouble in any way.

 In view of the tower crane production, supply and marketing , the use of the chaos , some of the informal enterprises put forward their own proposals.

For this proposal , the Director of the production license of the AQSIQ Liu Hongsheng September 24 in an interview with this reporter , said the AQSIQ replacement work will start in the next year , before the replacement, will be set up to review the General Administration Department , written by experts in charge of implementing rules renewal of an application for certification of enterprises, both will be in accordance with the Bye-laws , experts went to investigate , passing behind the new evidence available . Director Liu said that until the end of the replacement work , the State will organize a nationwide ban undocumented enterprise remediation activities. Wu Jianping production license AQSIQ Office added that while companies may order certified fraud moment , once identified , will always be revoked.

Some companies suggested using the crane ‘s strict inspection and supervision system, strengthen the operations staff.

Provincial CPPCC Standing Committee, China Group Chairman Xiachun Ting talked about his own views. His proposals are : the use of next year a new replacement machine, revoke batch production conditions no longer have factory production license. For new entrants to the crane manufacturing industry enterprises , can be like for pharmaceutical companies , like the practice after the implementation acquire a license to get a business license .

It is understood that the tower crane production license for five years for a change, and now the country’s permit had expired last year , the State wishes to start next year replacement work .

It is understood that the operation of the crane to be dangerous on the road than cars, inspection and qualification of the retirement system and the driver of the car is very strict , the crane is not the case , inspection mere formality, some areas have emerged cross-sectoral management chaos. In addition, nearly half of crane accidents have occurred during installation or removal , the main reason for this is that the accident installers and operators are not high quality . Do not operate the crane driver card also still open crane , the lack of strict management.

September 24 , Director of Special Equipment Department AQSIQ steel boiler Bureau Cui told reporters before due to the existence of “Everyone tube anyone regardless of ” cross- management situation , resulting in the use of safety supervision by crane in a disordered state. He said that in August this year, the State Council issued on the Sanding program AQSIQ where once again clear that after induction with training in security and operations staff of the tower cranes inspection and installation of a new , all the quality system organizations, other administrative departments shall not interfere . Cui Gang said that from October 1 this year , will be in a strong quality control system with crane into the security aspects , and rigorous training and certification driver personnel.

From July 1, 2001 , prohibiting the use of 20D derrick Tower crane , because this mass production in the early 1990s greatly simplified crane hazards . It was suggested that the country should also promote the practice . For 20D derrick tower cranes , if indeed there is a serious security risk , the experts in the preparation of replacement implementing rules should consider this issue and proposed “national cut-off” proposal.
xiachun ting also suggested , from safety performance , the state should promote the tower cranes foundation , minimizing or even ban ballast and rail mounted crane categories .

For this proposal , Liu Hongsheng , the Commissioner said , we are implementing rules replacement will fully consider how to strengthen the ballast and rail mounted quality crane safety performance requirements , but a total ban on the two types of products, you have to be with the other departments of the State Council .
