EDi Rail Enerpac Expertise: Hydraulic System Solution

Enerpac Hydraulic System for Downer EDi Rail Bogie Workshop


These photos document an ENERPAC hydraulic system that we specified and installed for Downer EDi Rail - Newport Workshops.

It consists of four 10 tonne double acting cylinders and two 5 tonne single acting cylinders, controlled by two separate pumps.


They are part of an apparatus for checking the trueness of machined wheels. The machining occurs at a portal lathe preceding this station on the production line.


The four 10 tonne cylinders lift the wheels (weighing around 2 tonne) evenly for checking. If they pass, the wheels are lowered, and the two 5 tonne cylinders tilt the vee blocks forward, allowing the wheel to roll off and continue along the production line.
