Overhaul and Renovation

Mill Liner Handler Machine

A mill liner handler is a self-propelled mobile structure on rails or wheels. Power for the movement of the telescopic arm and propulsion is provided by a central hydraulic structure on the installed base.

The scope of the project was re-engineering, procurement, overhaul, and renovation of mill liner handler machines made by McLellan*.

Challenge

Our client delivered a damaged mill liner handler machine to us for overhaul and renovation. The machine was damaged and out of service for 7 years.

Solution

The hydraulic circuit was sorted out by our engineering team. We replaced Sauer Danfoss hydro motors and Eaton-Vickers block valves with Bosch Rexroth components. Chassis were repaired in our service center.

We overhauled and renovated 3 sets, bringing the machines back to service during the years 2012, 2013, and 2016.

* McLellan is a custom-built equipment manufacturer for mining, construction, and agriculture applications, based in the USA.
