Product Details

Automatic Double-Cylinder Locomotive Wheelset Press

Railway Horizontal Wheel Mounting and Dismounting Press Machine

Hubei Heqiang Machinery is the No.1 manufacturer of wheelset presses in China. We can offer the most advanced wheel press machines available in the railway applications. The wheelset presses are used to mount and dismount all of the elements on the axle (wheel discs, brake discs, driven gears and bearings). With both single and double cylinder version available for option.

Application scope:

This fully automatic double-cylinder wheelset press is mainly used to mount, dismount and back pressure test the wheelsets of urban vehicles, passenger cars, locomotive etc. It can monitor and record the pressing data, so as to export the pressing curve report. Only one operator required to operate the press. With high-pressure oil injection pump for easy wheel mounting and dismounting.
