The tire girder lifting machine combines the tire hydraulic suspension drive technology, large tonnage hydraulic lifting control technology and pilot proportional multi-channel control technology. The flexible suspension system realizes the function of automatic leveling of the walking system of the beam lifting machine under different working conditions. The girder lifting machine has 64 tires in total, 32 tires are suspended, and 8 / 24 is driven shaft / driven shaft, which can realize the functions of straight travel, oblique travel and in-situ steering. Four point lifting, three-point balance operation mode, with panoramic cab.

The distributed control technology based on CAN bus is used to control the actions of engine, pump, motor, hydraulic valve and other components. The functions of synchronization, anti-skid and coordinated steering are realized.

Its legs are tower structure, which has the advantages of high strength and high stability. It can improve the working stability of the main engine as a whole, so as to realize the cross bridge construction operation, realize the bridge erecting function, and improve the utilization rate of railway construction equipment, which has a wide range of social and economic benefits.
