The YZG-550 is a manual hydraulic double-hook rail bender designed for on-site railway maintenance and bending of rails in the 43 kg/m to 75 kg/m range.
The YZG-550 delivers a bending force of 550 kN.
The work pressure is 57 MPa and the piston working stroke is 120 mm.
Yes. The machine is made of welded special steel with a compact structure, light weight and is designed for convenient dismounting and transport.
It is intended for rails weighing from 43 kg/m up to 75 kg/m. For unusual profiles or exact compatibility questions, consult the manufacturer or provide the rail drawing.
The YZG-550 is manual hydraulic equipment. Confirm with the supplier whether a hand or foot hydraulic pump is included or sold separately—packaging and accessories are listed on the supplier's packing list.
Operators should wear appropriate PPE (gloves, safety glasses, steel-toe boots), secure rails and machine before bending, never exceed rated load, relieve hydraulic pressure before disassembly, and follow local safety and lockout procedures.
Regular maintenance includes cleaning after use, inspecting welds and hooks for wear, checking hydraulic hoses and fittings for leaks, maintaining correct hydraulic fluid level and using manufacturer-recommended oil, and replacing seals as needed.
The YZG-550 is CE certified and undergoes 100% inspection as part of its quality control process.
The body is made of special steel and is welded for strength and reliable performance.
The no-load advance (efficiency) is specified as 1.5 mm per pump action; final precision will depend on operator control and setup.
Dimensions are provided per customer drawing. Contact the supplier to obtain detailed dimensional drawings for planning and integration.
Typical recommended spares include hydraulic seals, hoses and fittings, replacement hooks or clamps, and the appropriate hydraulic pump if not included. Check the supplier's parts list for exact items.
