Crane is mounted on ALL WD KamAZ-53228 chassis featuring wheel and interaxle differentials blocking and direct and transverse stabilizers. Chassis has 10 wheels: one side-wheel per each front axle and two per each rear axle. The below-mentioned characteristics nearly make it all-terrain crane.
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 3-sectional arm is 9.7 m which provides maneuverability and reduces space needed for the crane to move. In the extended position it’s 21.7 m, which enlarges its operating area and increases load-lifting height.
The boom is additionally equipped with 9 m jib which enlarges crane operating area and under-boom space among the 25-ton cranes.
Setting the jib from transportation position to the operating mode and back is done manually, without auxiliary loadlifting devices.
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.
