Big Crane Travels Long Distance for oil Refinery Project
Few cranes contain the capacity to lift a 771 tonne (893 US ton) object into place. Of these cranes which can be capable, even fewer are meant as being a series, standardizing the production process in order that transportation, rigging and maintenance ease are meant into each crane produced. Officials from the Yanbu Export Refinery in Yanbu, Kingdom of Saudi Arabia, recently experienced firsthand why people love a really crane design.
The Daelim Industrial Company – KSA, Saudi Arabia, hired heavy lifting specialists Integrated Logistics Company of Ahmadi, Kuwait, to lift and position a hydro treating reactor for that Yanbu Export Refinery. Weighing 771 t (893 US ton) which has a height of 67 m (220 ft) and radius of 3 m (9.8 ft), this massive reactor found in the oil refining process required specialized lifting equipment to soundly hoist it into position.
Integrated Logistics prepped the lifting equipment essential for the planned tandem lift, which included a Terex CC 8800-1 lattice boom crawler crane. As a whole, 67 flatbed, 20 low bed and also hydraulic trailers were required to make 1,250-km (776-mi) trip. ��It took approximately a week for those trailers to reach the website,�� says Mr. Manoj, DGM �C operations for Integrated Logistics.
The series-produced CC 8800-1 crane offers several design advantages which enables you to facilitate transport ease. ��The crane design considers transport requirements for virtually every market on the globe,�� says Christian Kassner, international sales manager for Terex Cranes.
��Every component is less than 3.5 m (11.5 ft) wide, and a lot components have a very shipping weight of a lot less than 40 t (44 US t). By making this 1,600-t (1,764-US t) crane to be a production model, Terex offers significant advantages over competitive designs which can be made like a one-off, custom-design crane to meet a unique market need.��
��Timely completion was important for this project,�� says Manoj, ��since there was clearly little margin because of heavy competition for the bidding stage. We appreciated the relative ease and speed where the crane was transported and rigged.��
Massive Lift
Once the crane��s components attained the Yanbu Refinery, Integrated Logistics�� nine crew members �C two operators, six riggers the other supervisor �C began assembling the CC 8800-1 plus the supporting crane equipment. The crawler crane was configured with a 78-m (255.9-ft) main boom for lifting the 67 m (219.8 ft) tall reactor. Hydraulic pinning from the boom segments increased the rate of boom assembly.
Crews used the absolute maximum 640 t (705 U.S. t) Superlift counterweight package with 295 t (325 US t) counterweight for the superstructure and 60 t (66.1 US t) central ballast. Counterweight radius to the tray was set at 25 m (82 ft). Two 800-t (882-US t) hook blocks and another 1,000-t (1,102 US t) Crosby shackle were instructed to lift the huge reactor, bringing the complete weight lift requirements to 810 t (893 US t).
After six days, Integrated Logistics�� crews were ready to hoist the reactor into position for Daelim. Lift conditions were ideal with favorable weather and wind speeds of less than 7 m/sec (15.7 mph), within the crane��s rating of 9.8 m/sec (21.9 mph).
That has a congested site that included other significant construction activity with the refinery, crews proceeded cautiously while using tandem lift. Working range through the lift ranged from three m (9.8 ft) into a maximum 24 m (78.7 ft). ��While using CC 8800-1 because main crane, we maintained a lifting speed of approximately 2 m/min (6.6 ft),�� says Manoj. ��The precision from the crane��s control system for this project contributed to the lift.��
The CC 8800-1 crane uses the IC-1 control system. It features touchscreen control with intuitive displays for operating ease, ground pressure indicator and extensive auto-diagnostic functions, making on-site troubleshooting simpler to increase uptime.
In a day, the 771-t (850-US t) reactor was hoisted and positioned on the congested site. Crews then began dismantling the crane to ship it time for the corporation��s headquarters in Kuwait. Integrated Logistics had the crane at the jobsite for just 10 days, allowing other projects to stay for the refinery.
��The reliability, maneuverability and accuracy from the CC 8800-1 were excellent, making it it the suitable crane due to this project,�� comments Manoj. ��The crane��s performance was appreciated by everyone who witnessed the project, including those from the Yanbu Refinery and Daelim Industrial Co �C KSA.
