Truck crane KS-55729-7K-31

The KS-55729-7K-31 truck crane with hydraulic drive, with rigid boom suspension, mounted on the MAZ-6312S3 chassis, is designed to perform construction and installation, loading and unloading operations at dispersed sites. The maximum lifting capacity of the KS-55729-7K-31 truck crane is 32 tons, the maximum lifting moment is 102.5 tm. The movement of the crane between sites is provided for on all types of roads. The drive of the crane unit is carried out from the chassis engine with a power take-off PTO. The drive from the chassis engine significantly improves the economic, environmental and ergonomic noise indicators. The hydraulic drive system is equipped with reliable hydraulic components from foreign and domestic manufacturers: planetary gearboxes with a high torque reserve. The crane is equipped with a four-section boom 31.0 m long, having an ovoid profile, which makes it more rigid and durable compared to a hexagonal profile. The telescoping system, consisting of one hydraulic cylinder and a system of block and tackles of sections 3 and 4, significantly lightens the boom and allows to extend all sections simultaneously, which reduces the time for crane operations. The KS-55729-7K-31 truck crane has an increased support contour - 5.45 x 6.1 m. For emergency folding, a mini-hydraulic station built into the crane's hydraulic system is provided, which allows in the event of an accident to quickly bring the crane to the transport position. The KS-55729-7K-31 truck crane fully complies with the standard loads, according to the requirements of the "Rules for the Transportation of Goods by Road" No. 272, can move on public roads in compliance with the requirements for axle loads. Additional options: - Using an additional counterweight weighing up to 6.0 t in operation improves the crane's lifting characteristics at medium and long outreaches. - To increase the lifting height, the boom can be equipped with a 9-meter lattice jib. The jib is supplied complete with a hook suspension with a lifting capacity of 4 tons for double reeving. - Oil cooler. - Video surveillance system for cargo and winding of the cargo rope on the drum. - Air conditioning.
