YLS-900 Hydraulic Rail Stretcher

The YLS-900 is a steel rail tensor (hydraulic rail stretcher) designed to stretch and align rails in track maintenance. It provides high pulling forces and uses a pump (petrol or electric) to operate its cylinders.

The maximum rated working pressure is 57 MPa.

The YLS-900 provides a maximum pulling force of 2 × 450 kN (two cylinders each capable of 450 kN).

The maximum cylinder working stroke is ≥ 500 mm.

The center distance between the two rods is 535 mm.

Locking is achieved by wedge clamps located on both sides of the rail head, which secure the rail during stretching operations.

The standard petrol pump is a Honda GXV160 with 4.0 kW power and a flow rate of ≥ 3 L/min. An electric pump option is also available (weight listed as 85 kg).

The main machine weighs 310 kg. The internal combustion (petrol) pump weighs 75 kg (not including tubes). The electric pump weighs 85 kg.

The petrol pump supplied is a Honda GXV160 engine (4.0 kW). For specific fuel type, consumption and starting instructions, follow Honda's engine manual supplied with the pump.

The YLS-900 uses wedge clamps on the rail head; compatibility with specific rail profiles and sizes should be confirmed with the manufacturer or your local Tiegong dealer to ensure proper fit and safe operation.

Regular maintenance includes inspecting cylinders and hoses for leaks or damage, checking hydraulic fluid level and quality, cleaning and lubricating clamps and moving parts, and following pump engine service intervals. Refer to the manufacturer-supplied maintenance manual for intervals and procedures.

The product comes with a 1-year warranty. For spare parts, service, or technical support, contact the manufacturer or your authorized Tiegong dealer.

The machine weighs 310 kg; use appropriate lifting equipment (forklift, crane, or pallet jack) rated for the weight and follow safe lifting practices. Secure the unit during transport to prevent tipping or damage. For exact lifting points and procedures, consult the user manual.

The listed weight for the internal combustion pump (75 kg) does not include tubes. Confirm with the supplier which hoses and fittings are included and order any additional lengths or fittings as needed.

Certification information is not listed in the basic specification. Contact the manufacturer or your local distributor to obtain certificates, test reports, or compliance documentation relevant to your region or rail authority.
