HYDRAULIC TRACK LIFTING AND LINING MACHINE

详情

This machine is composed of internal combustion engine, gear pump, multiple reversal valve, oil cylinder , track lifting mechanism, track lining mechanism, rail hooking mechanism, traveling mechanism, offline mechanism and manual hand pump,etc. Track lifting and lining mechanism achieves track lifting work through expansion of piston rod and track lining work is done through spacer pin to control the rotation and inclination of hoist cylinders to the track lining position .Cylinders of rail hooking mechanism and traveling mechanism are controled by a reversal valve, open and close of rail hook and lifter of frame are linkage, both of them are operated unitedly, This two action is completed simultaneously, which elimites the possibility of damage of machine that lifting the frame when rail hook is unopen because of misoperation, and improves security of the machine. It is the structure of drill key type that the open and close of rail hook, which can loosen rail automatically by virtue of the gravity of rail hook. The machine is of convenient operation and reliable performance. related products: track lifting machine, track lining machine, track jack, machanical jack
