YQB hydraulic lifter is a new type of lifter suitable for maintenance and repair of railway lines.
The biggest feature of this machine is that one machine can be used for two purposes.
It can also meet the requirements of ditching operations. Among them, the YQBD-245A dialer has a double-speed function.
Working principle: Swing the handle to make the plunger pump work continuously (suction and pressure oil), and press the hydraulic oil into the working cylinder. The piston extends out, pushing the lifting wheel to move vertically upward and horizontally. It generates an upward and horizontal thrust on the rails, so as to achieve the purpose of starting and setting the track.
