Rail Straightening and Bending Tools

During the laying, inspection, and daily maintenance of railway lines, the straightness of the rails affects not only the running smoothness and riding comfort of the train but also the line's operating safety and service life. Due to factors such as transportation, storage, welding, or long-term operation, steel rails often develop varying degrees of bending or deformation. To quickly and accurately restore the rail to its original alignment, it is essential to use specialized railway maintenance equipment—rail straightening and bending tools. The horizontal rail straightener & bender and vertical rail straightener we launched are the ideal equipment combination to solve this problem.

Horizontal Rail Straightener & Bender—A Powerful Tool for Lateral Straightening and Bending

The horizontal rail straightener & bender is used to correct lateral (left-right) bending or deformation in steel rails. It is ideal for applications such as new rail installation, rail replacement, track renovation, and rail joint welding. This tool is especially critical for curve alignment and maintaining smooth rail geometry.

Some models of the horizontal rail straightener & bender are equipped with a rail bending function, enabling cold bending of rails as needed to better adapt to on-site construction requirements.

Vertical Rail Straightener—A Targeted Solution for Vertical Deformation

The vertical rail straightener is specifically designed to correct vertical (up-and-down) deformation in steel rails. It is ideal for addressing issues such as localized railhead bulges, depressions, or overall vertical bending. Common use cases include post-welding cooling deformation, warping during transportation, or track surface irregularities caused by subgrade settlement.

Using a vertical rail straightener allows for rapid restoration of vertical alignment, improves track-laying efficiency, and ensures smooth and even rail surfaces.

Typical Application Scenarios

Rail straightening and bending tools are widely applied in various challenging environments where rail deformation frequently occurs.

• On heavy freight lines, continuous high axle loads can lead to complex rail distortions, including combined horizontal and vertical bending. The use of straightening equipment is essential for maintaining rail integrity and operational safety.
• In regions with significant temperature fluctuations, thermal expansion and contraction may cause wave-like bending of the rails, often accompanied by localized settlement. Such deformation can severely affect track alignment and must be corrected promptly to prevent long-term damage.
• At turnouts and transition sections, where stress conditions are more complex and multidirectional, rail geometry can easily become misaligned in three dimensions. Rail straightening and bending tools are critical in these areas for fine-tuning the track geometry and ensuring smooth transitions and safe train operations.

Structure of Horizontal and Vertical Rail Straighteners & Benders

AGICO’s horizontal and vertical rail straighteners & benders are all powered by manual hydraulic systems, eliminating the need for external power sources or electric pump stations. These tools feature a simple structure, easy operation, and excellent portability, making them ideal for railway construction sites and maintenance environments.

The equipment generally consists of the following main components (specific structure may vary slightly by model):

• Main Frame (Support Structure): Built from high-strength alloy steel to provide a stable load-bearing platform and ensure sufficient structural rigidity during the straightening process.
• Hydraulic Cylinder (Manual Pump): Either integrated or external, the hydraulic cylinder is driven by a manual lever to generate strong thrust force — no electricity required.
• Clamping Device: Securely fixes the rail in place, preventing any displacement or misalignment during the straightening operation.
• Press Head / Ram (Working End): Driven by the hydraulic cylinder, the press head or ram applies counteracting force directly to the deformed section of the rail for straightening.
• Adjustment Mechanism: Some models are equipped with lateral guide rails, knobs, or handwheels for precise positioning and control of the correction point.

Product Advantages

• Fully manual operation, no electricity required, suitable for remote and powerless construction environments.
• Compact structure, easy to carry, single-person operation.
• High hydraulic pressure, high correction efficiency, suitable for different grades of rails.
• Different clamp specifications can be selected, compatible with various types of rails, such as 43kg, 50kg, 60kg, etc.
