Rail Tensor
— Bidirectional Hydraulic Rail Tensor / Rail Tensor Machine
A robust, easy-to-operate bidirectional hydraulic rail tensor (rail gap adjuster) engineered for fast, safe adjustment of rail gaps on 43 kg/m through 75 kg/m rails. Compact, serviceable and built for field reliability — ideal for maintenance crews, track gangs and contractors who need fast, repeatable rail-gap increases or decreases with strong clamping force and multiple safety release methods.
Key features
Bidirectional operation: Adjusts rail gaps both larger and smaller without re-clamping.
Hydraulic power transmission: Manual hydraulic pump with oil medium for controlled, powerful action.
Wedge-type clamp: Compact wedge-iron clamping delivers high clamping force and secure grip.
Safety systems: Four independent safety devices to release jammed clamps quickly.
Field serviceability: Simple modular components — pump, hydraulic cylinder, separation/reset mechanism and clamps — for quick repairs.
Adaptable clamp position: Clamp can be repositioned along the same rail to complete both gap increase and decrease operations.

Note for technical buyers: if you require additional data (material grades, surface treatments, clamp jaw profile drawings, or hydraulic fluid spec), request the datasheet and CAD drawings with your RFQ.
- Designed for field safety: Four independent release methods are included so maintenance crews can rapidly free a trapped clamp in emergency or service conditions.
Simple, proven hydraulic architecture: Manual pump and piston assembly reduce complexity compared with motor-driven systems — easier diagnosis and repair on site.
Materials & workmanship: Wedge clamp design and compact cylinder ensure high clamp force and long service life when maintained per recommended schedule.
Transparency for buyers: We provide full technical drawings, spare-parts lists and maintenance instructions on request to support procurement, engineering sign-off and long-term reliability planning.
Support & aftercare: Factory technical support, spare parts and maintenance training can be provided — please state support needs in your inquiry.
Typical accessories & options

Why buy this hydraulic rail tensor?
Worksite efficiency: High thrust and long stroke let crews adjust joints quickly — fewer labor hours and less track downtime.
Versatile: One machine adapts to widely used rail weights (43–75 kg/m) and can both widen and narrow joints on the same rail.
Safety built in: Four safety devices allow rapid release of the clamp if it becomes jammed, reducing risk to track operations and helping maintain traffic schedules.
Low maintenance & simple operation: Manual hydraulic pump plus wedge-type clamps deliver strong, reliable clamping with minimal upkeep.
Portable footprint: Small footprint and manageable weight make it suitable for mining/rail access and varied terrain.
FAQs
Q:Can it both widen and shorten gaps?
A: Yes — the clamp arrangement and bidirectional hydraulic action allow the same unit to increase or decrease gap size on the same rail.
Q: Which rail sizes does it support?
A: Designed for 43 kg/m through 75 kg/m rails.
Q: What safety features are included?
A: Four distinct safety release mechanisms enable quick unclamping if the clamp becomes jammed; additionally a safety valve protects against overpressure (opens at ~50 ± 2 MPa).
