Product Description

Description

 Features for Pick up truck truck mounted  crane 25 ton ZTC250E552 in stock

 

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 6×4 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 8-speed gearbox which changes gear smoothly and is of simple structure and makes maintenance convenient.

The crane is fitted with a 33.3m 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 unique manual full proportional control incorporates the advantages of traditional lever control and pilot controlelectric-hydraulic . It not only reserves the merits of safety & reliability of original control structure and low maintenance cost, but also realizes that the working speed of actuating mechanism is only proportional to the opening degree of control valves rather than affected by the load. Furthermore, it has improved the speed-regulation performance. 

The slewing mechanism has the functions of protecting the crane automatically when the crane is overloaded, reducing the impacts, and activating hydraulic brake when the hydraulic control valve is in neutral position as well as free swing. In addition, it can automatically make boom, wire rope and lifted load slew simultaneously, and minimize the sway of boom and load while the crane starts or stops quickly, and accelerates or decelerates slewing.

We have made constant improvements on our products, for instance, adding radiator for hydraulic system and mounting hydraulic oil tank of large capacity on the slewing table. Therefore, the radiating performance of hydraulic system is improved and the continuous working hours are 2~3 times of that of the same trade's products.

The crane is equipped with high-quality load moment limiter which has such advantages as great precision and complete information shown on the display. In this way, the safe lifting operation can be guaranteed.
