With the continuous development of China's railway construction, the hydraulic straight rail device has entered the era of standardization. More stringent requirements for maintenance equipment. In terms of rail maintenance, we have introduced hydraulic rail bending machine  hydraulic straight rail device to correct the camber  straightness of rail. After many times of heat treatment  quenching, we have produced matching curve rails suitable for various rail models. This machine  the straight rail machine have greatly improved the current situation of the industry, especially in the mine construction. There are also manual rail bending products.

It is recommended that you hook the hook of the straightener on one side of the rail head, place the piston head on the other side of the rail head,  then turn the eccentric hand wheel to lock the straightener on the rail. At this time, screw the drain valve  insert the crowbar into the presser hand to perform the straight rail operation. After operation, loosen  open the oil valve, wait for the piston to retract,  then turn the eccentric hand wheel in reverse direction to lift the rail straightener off the rail.

Check the position of the rail leveler on the rail before loading the pump oil. The leveler shall be leveled, the hook ground shall be close to the top surface of the rail,  the hook, eccentric wheel  piston head at both ends shall be in good contact with both sides of the rail head.

When the pump oil is loaded, the action should  be too fast; when unloading, the eccentric hand wheel can only rotate after the piston head leaves the rail head side. Do  turn the eccentric handwheel during operation.

When the piston stroke reaches 70mm, the recovery spring in the cylinder is compressed. In order to avoid failure, the piston stroke shall  be greater than 65mm.

Double drain valve is a kind of safety protection device, which must be kept in good condition. If one drain valve fails  the piston cannot be reset during operation, the other drain valve can be opened for unloading. In operation, Z is easy to use the drain valve. When the operation is carried out at the seriously vertical wear part of the rail side, the wear part shall be provided with inclined plug iron. The rail straightener shall  be placed in the center of the track to ensure safety.
