Rail Maintenance Equipment and Measuring Instruments


Beijing YHD Railway Equipment (YHD) specialises in railway maintenance machines, including grinding, rail cutting, drilling and tamping solutions.

The company also provides equipment for measuring rail profiles, stress-free temperature testing systems, and rail flaw detection trolleys.

In addition, YHD offers training and maintenance services for rail flaw detection, grinding, welding and track measurement.

The G1 grinds rail heads and removes weld beads at welding joints.
The G2 grinding machine features a digitally controlled grindstone, with around -90° to 90° rotation, and a 65mm stroke going up and down. The position of the grindstone is displayed on a control panel.
The G10 rail milling machine allows operators to adjust its feeding rate and lock cutting plate at any time. The adjustable milling angle is from approximately −30° to 30°.
The lithium battery-powered, digitally-controlled T1B wrench is capable of tightening and loosening a total of 2,000 bolts in a single battery charge.
The heavy-duty multipurpose T4 wrench offers two functions in one unit. Its pivoting screw head allows vertical and horizontal fastening work.
The D13A ultra-light rail drilling machine automatically feeds in lubricant during operation, and drills accurately within 0.2mm. Its drilling stroke is 50mm.
C1 Gasoline Rail Cutter
High precision cutting with horizontal and vertical deviation less than 1%. Automatically adjustable cutter shield according to the movement of cutting wheel ensures highest safety requirement.
YHD supplies D5 internal combustion vibration tamping picks, which use non-impact methods that meet railway standard requirements and cause no damage to ballast or sleepers.

Grinding and rail milling machines
