Hydraulic rail lifting jacks are applied for safe rolling stock maintenance, providing precise elevation of locomotives and freight cars up to 300 tons with high-accuracy control.
A rail lifting system comprising four hydraulically synchronized jacks capable of simultaneously elevating an entire coach section. The apparatus consists of five core components: structural columns, lifting mechanisms, mobile hydraulic power units, load transfer platforms, and an electrical control system.
Application:
The Lifting jack is mainly used for the maintenance work of the construction vehicle to facilitate the maintenance and replacement of the bogie and other parts.
It is used for railway vehicle manufacturing companies and repair units to repair and replace the bodies, bogies and other parts of rail vehicles.It is not limited by the vehicle type, and can lift various types of vehicles, greatly improving the inspection and repair capabilities of hybrid vehicles.

· Dual Control System: Each hydraulic lifting jack operates via an independent control box, while a central console manages synchronized operation of all four units.
· Safety Interlock Protocol: Independent jack controllers interface with the main console through hard-wired interlocks, using open-run or conduit-protected cabling.
· Precision Drive Performance: All jack motors maintain rotational speeds within ±16 RPM of rated values, ensuring responsive elevation/lowering with synchronized motion control.
· Dual Mobility Configuration: Wheel-mounted bases enable manual workshop positioning, while integrated lifting lugs permit crane relocation.
· Adjustable Lift Range: Each jack provides infinite height adjustment within its engineered stroke limits.
