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.
