Regular maintenance is essential to keeping the national railway
network running. The replacement of worn pads is one of many tasks
that make up the maintenance program, and due to the vast number of
bogeys requiring service, a special tool was required to simplify
The tool was conceived, designed, and built in 10 working days. The
model was developed in Autodesk Inventor® and the frame was last
cut to precise standards. All other components were manufactured
in-house to ensure a small lead time.
Utilising off-the-shelf ENERPAC hydraulic components, the tool
generates 5 tonne of force, which is more than required but
guarantees smooth operation and long-term clamping. A foot-operated
air over oil pump controls the cylinder, due to it’s compact nature
and ease of operation.
