QL Railway Machinery Launches New YTF-400 Rail Positioning Hydraulic Tool for Efficient Track Maintenance

Zhengzhou, China – October 2025 – QL Railway Machinery, a leading Chinese manufacturer of railway maintenance equipment, has officially launched its latest innovation: the YTF-400 Rail Positioning Hydraulic Tool. Designed for global B2B rail contractors and infrastructure agencies, this high-performance tool delivers reliable, fast, and safe rail gap adjustment on mainlines, sidings, and urban transit networks.

The YTF-400 features a robust 400 kN rated thrust force and a 140 mm piston stroke, enabling efficient widening of rail joints-even under challenging track conditions. Its patented anti-jamming mechanism prevents "locking" during operation, significantly reducing downtime and enhancing crew safety.

The YTF-400 hydraulic rail gap adjuster in action-ideal for high-efficiency track maintenance crews.

Key Technical Specifications

• Rated Thrust Force: 400 kN
• Piston Stroke: 140 mm
• Operating Pressure: 52 MPa
• Efficiency (No-load): ≥2.0 mm per cycle
• Max Handle Torque: ≤450 N·m
• Weight (with hydraulic oil): ≤84 kg

Engineered for portability and durability, the YTF-400 weighs under 84 kg and requires minimal operator effort-making it ideal for remote locations, high-traffic corridors, or tight urban maintenance windows where speed, safety, and compliance are non-negotiable.

"This tool addresses a real pain point in rail maintenance: slow, unreliable gap adjustment that delays track possession windows," said a QL Railway product engineer. "With the YTF-400, crews can complete jobs faster, safer, and with full compliance to international maintenance standards."

As a China-based manufacturer certified to ISO 9001 and EN 15085, QL Railway Machinery supplies hydraulic rail tools to over 30 countries. The YTF-400 is now available for global B2B procurement with OEM/ODM support.
