The YLS-900 hydraulic rail stretcher is designed for stress release of continuously welded rails (CWR), laying long rails, and thermit welding of rails on the track.
It is suitable for various types of rail ranging from 43 kg/m to 75 kg/m.
The maximum rated working pressure of the YLS-900 is 57 MPa.
The YLS-900 can generate a maximum rail pulling force of 2 * 450 kN.
The maximum stroke of the working cylinder is 760 mm.
The weight of the YLS-900 is 310 kg.
Yes, there is an optional petrol pump station available, specifically the HONGDA GX160.
The power rating of the YLS-900 is 4 kW.
The rate of flow for the hydraulic system is ≥ 3 L/min.
The YLS-900 uses iron wedges to clamp the rail web for locking during operation.
Yes, the YLS-900 is also used for rail joint adjustment in sections for ultra-long CWR.
Stretching the rail in a zero stress state allows it to be adjusted to the length required when the rail temperature is locked, facilitating proper installation or repair.
Yes, proper training is recommended to ensure safe and effective operation of the hydraulic rail stretcher.
The YLS-900 includes safety locks and iron wedges to secure the rail during operation, helping to prevent accidents.
Regular maintenance includes checking hydraulic fluid levels, inspecting the pump station, and ensuring all components are functioning properly to prolong the tool's lifespan.
