Rail Pullers and Tensors

Hydraulic rail pullers and rail tensors are essential equipment for quickly adjusting track gap width, repairing track gap imbalances, and relieving stress on seamless lines while laying long rails. Equipped with precise hydraulic control technology, they help railroad workers to ensure the safe and stable operation of rail tracks, extending their service life and making them suitable for seamless line laying, daily maintenance, and emergency repairs.

Hydraulic Rail Puller

The hydraulic rail puller is a tool specially used for maintaining rail tracks, and its role is very important. The hydraulic rail puller mainly consists of a running wheel assembly, a lever assembly, a joystick assembly, an oil tank assembly, a reset spring, a spring plate assembly, a rear clamp assembly, a small and large safety pin assembly, a working pressure cylinder assembly, a front clamp concrete and a wedge iron.
The function of hydraulic rail puller:

• Adjust the width of the rail gap: Keep the spacing between the rails within the appropriate range. Correctly positioned rails can reduce the shaking of the train during travel, improve the riding comfort of passengers, and reduce the friction between the train and the track, extending the service life of the steel rail.
• Release the stress from temperature: Rail puller can also repair the track gap imbalance caused by temperature changes. When the temperature changes greatly, the steel rails often expand due to heat or contract due to cold, causing changes in the track gap. If it is not adjusted in time, the track gap imbalance may cause the train to run unsteadily or even derail. The rail puller works as a track gap adjuster can keep the track gap in a reasonable balance state through automatic or manual adjustment.

Hydraulic Rail Tensor

What is Hydraulic Rail Tensor Machine

Rail tensors are suitable for stress relief of seamless lines and long rail laying and for thermite welding of rails on the line. During on-site construction, within a certain range below the locking rail temperature, the equipment is used to forcibly stretch the rails in a zero-stress state to the length at the locking rail temperature and then re-lock or perform thermite welding of the rails.

Hydraulic Rail Tensor Features

Compared with similar products, rail tensors from AGICO has the characteristics of innovative design, light body, easy operation, no damage to the rail head working surface, etc. It is suitable for various rail types. The hydraulic rail puller is an ideal machine for track laying, adjusting large rail gaps during maintenance and stress relief.

Difference Between Rail Puller and Rail Tensor

Rail pullers can temporarily replace rail sensors in extreme situations or special scenarios, but they are not an ideal choice due to their limited accuracy, efficiency and safety. The principle of "special machine for special purpose" should be followed in railway maintenance to ensure adjustment effect and operation safety.

• Local rail gap adjustment of seamless lines
  In seamless lines, if the local rail gap is abnormal due to construction or maintenance (such as turnouts and bridge joints), the rail puller can indirectly change the rail gap width by stretching or compressing the rails. However, it requires manual measurement and calibration, and the operation is complicated.
• Temporary adjustment in emergency maintenance
  If the rail tensor is not available, the track puller can be used to apply tension or pressure to the rails, and the overall adjustment can drive the rail gap at the joint to change. However, the accuracy is low and it is only suitable for rough correction.
