Technocrane Debuts BIGMAX Patent-Pending Hoist Mechanism
The newest AO series BIGMAX articulated tower crane by Technocrane Inc., Surrey, British Columbia, will be the initially three crane types featuring the manufacturer’s POWERLIFT patent-pending hoist mechanism. It truly is scheduled for release within the first 1 / 2 2007.
Engineered using a built-in anti-two-block feature within the hoist, the tower crane provides up-and-over features of an ordinary knuckleboom. Furthermore, for the reason that crane can lift or lower a large quanity sheer and down, it can position a physical object (over hold down bolts, for example) precisely.
Unlike a winch, which can be externally mounted, the POWERLIFT is often a cylinder-actuated hoisting mechanism that’s completely built into the boom. Also unlike a winch, that includes a reduced hoisting capacity along with the speed is correspondingly increased with each additional wrap of cable, the POWERLIFT smoothly lifts its rated load at the constant speed with less anxiety about the hoisting cable.
“After i came out the concept in writing to some quantity of crane experts, each of them think it is ‘kinda clever as well as a wise decision,’” says Todd Slobogean, Technocrane president and POWERLIFT inventor. “However, rrt had been only if they got to discover it work and operated it [them to] were quite fascinated. Actually, it was only then that they can fully understood the idea.”
Two larger models are projected to the last half of 2007. Maximum load moment with the next larger model is predicted being 45,000 foot-pounds having a maximum horizontal reach of 21 feet along with a maximum lift capacity of 6,200 pounds. That has a maximum capacity of 58,000 foot-pounds, the best model should have a horizontal reach up to 22.5 feet as well as a lift limit of 7,800 pounds.
The primary production model of the AO 45 has become built which is waiting field testing. Having a load moment of 32,300 foot-pounds (4.5 t/m), it provides a maximum horizontal reach of 19.3 feet and also a maximum lift capacity of 4,300 pounds. Maximum lift capacity on the tip is going to be 1,625 pounds. It will be officially unveiled in the ICUEE show from the fall, using the manufacturer.
With this tower crane, Technocrane offers target municipalities, utility companies, construction, and transport companies, and any application where a versatile multi-purpose crane is essential. Created for use in typical knuckleboom applications, this can be a fit for work sites “where knucklebooms cannot reach, for instance low-overhead and below-ground applications, through windows and doorways where objects must be placed,” says Slobogean.
Multiple industries can have desire for this kind of technology, he admits that, including water and sewer construction; sump pump installation and service; pre-cast products; residential; road construction and signs; and oilfield for applications including pump-jack maintenance. Other markets include propane delivery and aquaculture. “As being the ‘inventor’, I’m obviously partial with it, and quite pumped up about the POWERLIFT and its particular potential,” adds Slobogean.
