50ton truck crane:

ZTC500H5522 truck crane is a new generation of high-performance product.

The performance parameters such as lifting height, main boom length, working speed and lifting capacity of the crane are at the current international leading level.

The product is a full-slewing, telescopic boom-type, hydraulic-controlled proportional-controlled truck crane. It adopts the company's self-made full-drive four-bridge special chassis.

It has a wide field of vision, luxurious decoration and comfort, 8×4 drive, hydraulic power steering, and light weight. flexible.

The product adopts the latest hydraulic control proportional directional control valve and variable pump plus gear pump system, which makes the working capacity of each actuator fully exerted,

and the hydraulic control pilot handle is operated, which can realize the main and auxiliary lifting, variable amplitude, rotation and telescopic mechanisms.

The combined action between the two greatly improves the efficiency of the crane. It has the characteristics of light and flexible operation, stable and reliable work, stepless speed regulation and so on.

In the hydraulic system, safety devices such as overflow valve, balance valve, hydraulic lock and brake valve are provided to prevent oil passage overload and avoid accidents caused by oil pipe rupture.

The crane is equipped with a variety of safety devices such as a torque limiter and a complete lighting system to ensure safe and reliable operation and easy night work.
