DETAILS OF TADANO Truck Crane GT-250E:

1、TADANO Truck Crane GT-550E  Adopts self-made special purpose chassis with 6x 4 drive Ergonomic streamline semi-mounted drivers cab with double wing door, which has obtained a national patent, makes it convenient for rear rider to get on and off on the cab.

Adopts Weichai Steyr engine which is specially developed for those cranes that often travel at low speed, this kind of engine cannot only produce large output torque when it starts and increase the traveling speed quickly, but also has excellent starting performance and good grade ability.

2、TADANO Truck Crane GT-550E  Equipped with eight-speed gearbox which changes gear smoothly and simple structure makes maintenance convenient.

Distinctively-designed circular arc sliding block (having obtained a national patent) makes the stress distributed more evenly, load carrying capacity stronger, and adjustment easier.

3、TADANO Truck Crane GT-550E  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.
