Products Description
Hydraulic rail tensor rail puller
Hydraulic Rail Puller Rail Tensor
It’s suitable for rail 50kg/m,60kg/m and 75kg/m type rail stress relief and seamless long rail relaying. While operating in the
field at a certain temperature range being lower than the rail locking temperature, by employing this machine, the length of a
rail with zero-stress can be forced to stretch to a length at locking temperature, then re-lock the rail. By locking the rail
waist, it will not hurt the rail head surface, one machine with a variety of configuration meets the field work in different ways,
it possesses features of unique design, light weight, simple & convenient manipulation and powerful rail pulling force. The
machine can not only be used for repairing the broken rails of seamless tracks, but also can be used for stress relief of seamless
tracks and section adjustment of track seams in common tracks, and is suitable for various rail types. Using this product can
change the traditional method of repairing broken rails, that is, re-welding in situ without inserting short rails, saving time ,
Save labor, expand the operating rail temperature range, and prevent the actual lock rail temperature from changing

1. What is the Hydraulic Rail Stretching Machine used for?
It's used for rail stress relief, seamless long-rail relaying, repairing broken rails (re-welding in situ) and section adjustment of track seams by stretching rails to the locking length before re-locking.
2. Which rail profiles and weights is this machine compatible with?
It is suitable for rail types of 50 kg/m, 60 kg/m and 75 kg/m.
3. What are the key technical specifications of the model shown?
Model LG-900: working pressure 67 MPa, maximum tensile force 900 kN, cylinder stroke 500 mm, locking form: wedge iron lock.
4. How does the rail stretching process work?
When the field temperature is lower than the rail locking temperature, the machine stretches the zero-stress length of the rail to the length corresponding to locking temperature, then the rail is re-locked (clamped) so the rail head surface is protected while the required stress state is obtained.
5. Can this machine be used to repair broken rails without inserting short rails?
Yes. The machine enables re-welding in situ by stretching and locking the rail to the required length, saving time and labor compared with inserting short rails.
6. What type of power system does the machine use?
It operates with a hydraulic system driven by an automatic hydraulic pump (hydraulic power unit). Confirm with the supplier whether the pump and power unit are included or supplied separately and the required power specification.
7. Is the machine portable and easy to operate in the field?
Yes. The design emphasizes light weight, simple and convenient manipulation, and multiple configurations to meet different field needs. Operators should still be trained in safe use.
8. What safety precautions should be followed when using the rail tensor?
Always use appropriate PPE, ensure personnel are trained, never exceed the rated working pressure (67 MPa) or maximum tensile force (900 kN), verify correct clamping/locking before applying force, keep bystanders clear, and follow local railway safety procedures.
9. What routine maintenance is required?
Perform regular inspection of hydraulic hoses, seals and fittings; maintain hydraulic fluid level and quality; clean and lubricate moving parts; inspect the wedge lock and clamping surfaces for wear; and replace worn parts promptly.
10. Will using this machine damage the rail head surface?
No. The machine is designed to lock the rail waist (not the head), which prevents damage to the rail head surface during stretching and locking.
11. Can the machine be used on both seamless (continuous welded) track and conventional track?
Yes. It is suitable for stress relief and adjustment on seamless tracks, and for section adjustment of track seams on conventional tracks.
12. What accessories and configurations are available?
Typical accessories include hydraulic hoses, clamps/grips sized for different rail profiles, wedge locks, and the hydraulic pump/power unit. Multiple configurations are available to suit different field methods—contact the supplier for specific accessory lists and options.
13. What operating temperature range does the machine support?
The machine is intended for use when field temperature is below the rail locking temperature and is designed to expand the operable rail temperature range. For specific operating temperatures and limits relative to rail locking temperatures, consult the supplier or engineering guidelines.
14. How do I get pricing, lead time, spare parts or warranty information?
Contact the manufacturer or authorized distributor for current pricing, lead times, spare-part lists, training options and warranty terms. Provide rail profile and project details so they can recommend the correct configuration.
