Working principle:

Through the bending beam and hook beam fixed to the rail, and then driven by the hydraulic pump station, the bending rail oil cylinder on the straight beam is driven to control the extension and retraction of the oil cylinder, so as to achieve the purpose of straight rail.

Operation

Usage Instructions:
1. Pre-use Inspection
① Ensure the oil level in the tank reaches three-quarters full.
② Verify the positioning mechanism moves smoothly and reliably.
③ Ensure all connecting fasteners are secure and hydraulic cylinders are free from leakage.
2. Operating Procedure
① Position the entire unit atop the rail head. Raise the running wheel lever 13 to press the running wheel 10 onto the rail head. Advance to the section requiring straightening. Insert the rail lifting wedge attached to the lifting hook 11 beneath the rail. Adjust the position of the adjustable jack 12 as required for the task. Withdraw the locating pin and depress the running wheel lever to engage the adjustable jack 12 against the rail crown. Simultaneously position the lifting hook 11 over the section requiring straightening.
② First, move the directional valve control handle 3 to the oil supply position. Then insert the hand lever 1 into the oil pump pressure sleeve. Operate the hand lever up and down to extend the piston rod (cylinder head 8), generating thrust force. Apply straightening force to the rail via the hook at the rail joint to complete the straightening process.

③ Upon completion of straightening, move the directional valve control lever 3 to the return position. Operate the hand lever up and down to retract the piston rod (cylinder ram 8). Raise the running wheel lever 13 upwards and engage the locating pin, allowing the running wheel 10 to rest on the rail. The unit can then be wheeled along the rail to the next workstation.

④ Typically, the rail straightener completes both level and straightness adjustments in a single operation. Should substantial adjustment be required beyond one pass, the cycle may be repeated.
