Sandvik Mining sees a machine whose vital components are failing and reaching the end of their life as an opportunity, a chance to rebuild the equipment and bring it back to a state in which it is once again operating in a productive, reliable and economical way. These vital components may include an engine, axles or hydraulic system for example, which could potentially become a financial burden in terms of machine downtime, repair work and lost productivity.
Sandvik has rebuild capabilities in workshops worldwide, offering rebuild services to customers on all continents. A simplified explanation of the process involved in rebuilds is described below:
- Customer requests a machine rebuild
- The machine is assessed by Sandvik to determine whether a rebuild is the best option
- If so, the machine is decommissioned, cleaned and disassembled in a Sandvik workshop
- During the cleaning process the handling of oil and its separation is managed in a responsible way.
- Vital components are rebuilt in line with OEM standards and all parts that meet quality requirements are reused.
Examples of these are:
- Old frames, which can be crack tested, straightened, machined and reused in favour of replacing them with new frames
- Engine blocks, housings for torque convertors, transmission and axles as well as cylinder barrels are all components that can also be reused
- The machine is re-assembled, re-commissioned and tested before being returned to the customer for operation
