The YQ-150 is a portable hydraulic rail lifting machine (track jack) designed for lifting and positioning railroad rails during track maintenance and construction. It is applicable to all types of rail for track lifting operations.
Rated force: 150 kN; Max force: 200 kN (manufacturer notes combined operation can achieve ~199 kN); Max lifting distance/height: 120 mm; Max working pressure: 60 MPa; Max operating torque: 500 N·m; Machine weight: 25 kg; Overall size: 400 × 180 × 465 mm.
The YQ-150 has a maximum lifting capacity of 15 tons (approx. corresponding to its rated force of 150 kN).
The jack has two support positions: when the rail is in a low position it sits on the supporting plate of the lifting lever and bears up to 150 kN; when the rail is in a high position it sits on top of the hydraulic cylinder and can bear up to ~199 kN. During operation both functions can work together for secure lifting.
Do not exceed the rated force (150 kN) or the stated maximums (200 kN, 60 MPa, 120 mm travel). Always follow safe lifting practices, secure the rail after lifting, and never work under an unsecured load.
Operators should wear safety boots, gloves, eye protection and high-visibility clothing. Keep clear of pinch points, never stand under a lifted rail, ensure stable placement of the jack, and use chocks/blocks as required.
Place the jack under the rail in the appropriate position (supporting plate or cylinder top), ensure stable footing, connect and operate the hydraulic pump or lever per the pump instructions to lift to the desired height (≤120 mm), secure the rail, then carefully lower by releasing hydraulic pressure slowly.
Regularly inspect for hydraulic fluid leaks, damaged hoses, worn seals or bent components. Keep the jack clean and lubricate pivot points. Periodically change hydraulic oil and bleed air from the system per the manufacturer's schedule. Store dry and protected.
Common spare parts include seals, valves, cylinders, pistons, and hydraulic hoses. Availability depends on supplier; contact the manufacturer or dealer (brand: Tiegong) for specific parts and part numbers.
Typical accessories include a compatible hydraulic hand or power pump, pressure hoses, supporting plates/adapters for different rail profiles, carrying case or transport bracket, and safety blocks/chocks. Confirm exact accessory compatibility with your supplier.
Yes. At 25 kg and compact dimensions (400 × 180 × 465 mm), the YQ-150 is designed to be lightweight and portable for field use by track crews.
The unit is constructed from steel for durability and strength, designed for the demands of railroad track maintenance with a novel compact structure and reliable components.
The product description does not list specific certifications. If you require CE, ISO or other certifications, request documentation from the supplier or manufacturer (place of origin: Liaoning, China; brand: Tiegong).
Store the jack in a dry, clean environment, protected from corrosive chemicals and extreme temperatures. Drain or relieve hydraulic pressure before long-term storage. Secure the unit during transport to prevent impact or deformation.
Contact the supplier or manufacturer (brand Tiegong, place of origin: Liaoning, China) or your local dealer for warranty details, technical support, ordering, and to confirm lead times, pricing and available options.
