The Hydraulic Rail Bender (also known as a Hydraulic Rail Straightener) is a critical piece of railway maintenance equipment that operates on hydraulic principles. It is designed for the precise bending, straightening, and shaping of steel rails. By applying controlled force, it effectively corrects deformations such as bending, lateral curvature, wave wear, or warping caused by long-term use, temperature fluctuations, or external impacts. This process restores the rails to their designed linear or curved alignment, ensuring track stability, operational safety, and meeting the high-precision requirements of modern railway engineering.

AGICO Rail Bender Models

YZG-550 Double-Hook Hydraulic Rail Bending Machine

This model features a unique double-hook design enabling bidirectional bending/straightening. It is particularly suitable for correcting horizontal defects directly on the track without removing the rail, such as on thermite-welded long rails and switch rails. Its split-type structure (heaviest component ≤75kg) and long 120mm piston stroke balance portability for field transport with operational continuity, reducing the need for tool repositioning and improving single-point correction efficiency.

 

YZG-530 Hydraulic Rail Bending Machine

This is an economical and lightweight manual hydraulic model, weighing only 58 kg. It is well-suited for horizontal straightening or bending of light to medium rails up to 50 kg/m. It allows for fine adjustments within a 3mm range through precise hydraulic pump control and is equipped with triple safety mechanisms: overload protection, a hydraulic lock, and an emergency brake, making it simple and reliable to operate.

 

YZG-750III Hydraulic Rail Bending Machine

As the powerful choice for heavy-duty horizontal straightening, it offers a rated straightening force of 650kN, capable of handling various heavy rails from 43-75 kg/m. The body is welded from special alloy steel for high reliability and stable operation in extreme temperatures from -30℃ to 50℃. Its split design separates the hydraulic power unit from the main assembly, ensuring strong power while facilitating transportation and maintenance.

 

YPG-1000 Hydraulic Vertical Rail Bender

This is the specialized equipment in the series for correcting uneven (high-low) rail joints. It focuses on vertical straightening and can perform on-track correction of bent or depressed welded joints without removing the fishplates, offering high efficiency. Although the entire machine is heavier (190kg), it is equipped with travel wheels for easy movement along the track, making it a key tool for engineering departments during major overhauls and emergency repairs.

 

Selection Guide Summary

You can quickly filter models based on your primary straightening need:

For horizontal (left-right) bending or straightening of rails:

• Need bidirectional bending capability and in-situ on-track operation: Choose YZG-550.
• Working on light to medium rails up to 50kg/m, prioritizing lightweight and economical operation: Choose YZG-530.
• Working on heavy rails from 43-75kg/m, requiring maximum straightening force: Choose YZG-750III.

Specifically for vertical (high-low) straightening of rail joints: The specialized model YPG-1000 is essential.

If you can specify the rail specifications you plan to straighten (e.g., 60 kg/m) and the main type of correction needed (e.g., lateral bend of long rail, depressed joint, etc.), we can provide more specific selection analysis for you.
