Heavy duty lifting platform

Heavy duty lifting platform is consist of four 35-ton screw jacks, two angle bevel gearboxes, one gear motor, couplings, drive shafts and mount parts. Note: the United States customers prepare the 13.5 meters lifting screw by themself. Worm gear screw jacks are very good in multiple jack systems, because the torsional deflection of connecting shafts and couplings has little effect on positioning. Under heavy load, worm gear screw jacks are not designed for high use or heavy duty cycle applications.
