- 28 m boom lenght
25-ton mobile crane KC-55713-5V. The crane is designed for loading/unloading and construction/assembly operations. The crane is mounted on KamAZ-43118 three-axle all-terrain chassis equipped with tire pressure adjustment system and wheel-differential blocking. Tire pumping system allows to pump the tires up on the go, depending on the road paving which increases its terrain crossing capacity. This allows for crane operating in hard-to-reach areas, including oil and gas pipeline construction sites or field production sites.
Crane is operated via two axial-piston hydraulic pumps, which are set to operation by the carrier engine through the gearbox and additional PTO. Crane mechanisms have individual drives with independent control. Crane hydraulic system ensures smooth control of all mechanisms with wide range of operations adjustment levels, and allows for simultaneous combination of load-lifting operations.
Initial length of 4-sectional arm is 9.5 m which provides maneuverability and reduces space needed for the crane to move. In the extended position it’s 28 m, which enlarges its operating area and increases load-lifting height.
Support contour solution (4.9 x 5.8) allows the crane to operate in 360 degrees range and minimize the number of moves during operation. Thus, the model’s function and performance beat those of analogous models. The outriggers use allows for the crane operation in confined area. Load-lifting and swing planetary-type gear with disc brake meets the modern requirements to load-lifting machines. A few crane units have imported components which do not need replacement or repair during the whole run life. Autonomous diesel heater is sued for cab heating.
The arm can be telescoping while having weight on its hook which allows the crane to perform the following operations: place cargo at hard-to-teach spots, transport it through mounted framework. The outriggers use allows for the crane operation in confined area. Crane operating is safe due to lots of sophisticated devices, including microprocessor load limiter with operational parameters indication on the operator’s display up in the cab. The device protects the crane from overloading, featuring coordinate protection necessary for operation in confined area. It also has integrated telemetry recording unit (so-called “black box”) and hazardous voltage protection module allowing for work close to power lines.
