Simmons DDP-600 Wheel Demount Press
The Simmons DDP-600 Dual End Demount Press disassembles wheels from railway wheel sets. It has a maximum force capability of 600 tons and is capable of demounting a wheel set every 150 seconds (including loading and unloading).
The machine consists of a hydraulic cylinder beam assembly at each end of the press. Both rams have embedded distance transducers to provide ram and axle position information to the operator at all times. The press can be recessed into a shallow pit to optimize the working height of the press and accept wheel sets from embedded shop rails. It can also be used entirely above floor to minimize the installation costs.
The press is capable of demounting a wheel set every 150 seconds. The load and unload time varies depending on the optional handling equipment selected.
