Design of Hydraulic Iacking System for 1000 ton Concave Girder Transport Truck

The jacking system of 1 000 t girder carrier plays an important role in lifting performance of prefabricated box girder from girder carrier. Aiming at the jacking system of 1 000 t beam truck, the jacking force is obtained through detailed calculation. Considering the rated lifting speed of 1 000 t beam truck, the hydraulic system is designed to meet the needs of lifting when the maximum load, so as to ensure the normal lifting and lowering of 1 000 t beam truck at the rated speed when the rated load; At the same time, it makes the jacking cylinder rise and fall stably, not overspeed, and has achieved good effect in practical application.
