50T ZOOMLION Hydraulic Truck Crane/Half Cab 50T ZOOMLION Mobile Truck Crane/ZOOMLION QY50D531 Truck Crane

This type of truck crane, one of the classic products in the same trade, has earned a good reputation from the customers.

The truck crane adopts self–made special-purpose chassis with 8×4 drive. The ergonomic streamline semi-mounted driver’s cab with double wing door, which has obtained a national patent, makes it convenient for rear rider to get on/off cab.

The crane adopts WEICHAI Steyr engine which is specially developed for those cranes that often travel at low speed. This kind of engine not only can produce large output torque when it starts and increase the traveling speed quickly, but also has excellent starting performance and good gradeability.

The crane is equipped with 9-speed gearbox which changes gear smoothly and is of simple structure and makes maintenance convenient.

The crane is fitted with a 42m long hexagon-section boom which is made of high-strength steel, so the boom has strong resistance to bending and torsion. The distinctively-designed circular arc sliding block (having obtained a national patent) makes the stress distributed more evenly, the load carrying capacity stronger, and the adjustment easier. The local rigidity in boom supporting point is good, which has improved the lifting capacity on boom with same thickness and achieved the goal of greater lifting capacity on lighter boom.

The boom applies an arbitrary telescopic type which can improve the stability of crane when it works with large working radius. (When boom telescopes in different sequence, the position of boom’s centre of gravity is adjusted accordingly.)
