Rail Gap Adjuster

AGICO Hydraulic Rail Gap Adjuster

The AGICO Hydraulic Rail Gap Adjuster is a precision device specifically designed for railway track maintenance. It is used to accurately adjust rail joint gaps caused by temperature fluctuations, mechanical stress, or construction factors. As one of the popular maintenance machines under AGICO Rail, it utilizes hydraulic power to provide controlled adjustment of track gaps, gauge, and expansion joints, ensuring smooth and safe train operation.

This equipment is primarily used for the local adjustment of gaps on jointed tracks. It precisely controls the gap size hydraulically, keeping it within permissible limits. Unlike a rail tensor used for stress relief in continuously welded rails (CWR), the gap adjuster does not alter the overall stress state of the rail. Timely and precise gap adjustment effectively reduces the risk of derailment, minimizes wheel-rail impact, significantly extends the service life of track components, and lowers long-term maintenance costs.

AGICO offers both unidirectional and bidirectional models, suitable for various rails from 50 to 75 kg/m. The unidirectional type features a simple structure, offering cost-effectiveness and reliable performance. The bidirectional type provides both push and pull functions, significantly improving efficiency, especially in confined spaces. As a manufacturer with over 20 years of experience, we are committed to providing efficient, reliable equipment solutions and cost-effective services for all types of railway maintenance organizations.

Advantages of Rail Gap Adjusters

Choosing an AGICO Rail Gap Adjuster means opting for a smarter, safer, and more reliable maintenance method.

Millimeter-Level Precision Control

Utilizing precise hydraulic cylinders with measurable strokes and clear scale indicators, the rail gap adjustment accuracy can be strictly controlled within ±1 mm. This eliminates human adjustment errors at the root, reducing potential risks caused by improper gaps by over 60%.

Exceptional Operational Efficiency

Traditional manual adjustment requires multiple workers and is time-consuming. Using AGICO equipment, a single adjustment operation can be shortened to 3-8 minutes, improving overall efficiency by 5-8 times. This significantly reduces line possession time, creating greater value for operations.

Robust Environmental Adaptability & Safety

• Wide Temperature Range Operation: Core components are specially treated to operate stably in extreme ambient temperatures from -30°C to +60°C.
• Comprehensive Safety Protection: All models feature a four-level safety mechanism and an overload protection system. When the system pressure reaches the preset 52 MPa safety threshold, the relief valve opens automatically, effectively preventing equipment overload damage or plastic deformation of the rail.
• Ergonomic Design: Features a foldable handle designed for ergonomics, with an operating force of less than 450N. The non-slip rubber base and magnetic fixing devices ensure stable positioning of the equipment on the rails, guaranteeing safe operation.

Rugged Durability & Easy Maintenance

The main structure uses high-strength alloy steel, with key moving parts treated for wear resistance and rust-proof coating. Unidirectional models boast a simple structure with an extremely low failure rate; bidirectional models are reasonably designed for easy maintenance, ensuring long service life and high availability even in harsh maintenance environments.

Applications

The AGICO Rail Gap Adjuster is a powerful assistant in various railway maintenance scenarios:

• Standardized Rail Gap Adjustment: Periodic adjustment of rail joint gaps according to seasonal temperature changes to prevent track buckling in summer or joint pull-apart in winter.
• Pre-Welding Operations: Precisely moving rail ends before flash-butt welding or thermite welding to reserve the perfect gap and achieve accurate alignment.
• Turnout & Special Section Maintenance: Used to adjust the longitudinal position of components like switch rails and frog points, eliminating impact and noise caused by improper displacement. Especially suitable for areas with strict geometric requirements like bridges and tunnels.
• Emergency Incident Handling: Can quickly push together or pull apart broken rail gaps in case of rail breakage, creating conditions for subsequent emergency repairs.
• Track Overhaul & Renovation: Controlled shifting and fine-tuning of rail segments during long rail laying, stress release, or track realignment projects.
