Machine prior to overhaul
Overhaul completed, outer door refitted and ready for re-paint
Following a major failure during operation, a large flooring, MDF and OSB manufacturer asked Rotec to carry out extensive repairs on an industrial wood chipper.
Owing to the failure occurring whilst the machine was in use, the Maier Wood Chipper machine had suffered severe damage internally and so required a thorough repair and overhaul service.
After Rotec engineers stripped the machine and checked all components, it became apparent that the shaft bearing sleeves had failed, worn the housing and as the blades had come away during the failure, many internal parts were damaged and required either replacement or upgrading.
As the customer had issues with levelling up the impellor blades, Rotec checked the laser alignment and then ‘clocked’ the rear datum locating ring support pads on the machine. The support pads were found to have a 0.7mm difference in their positioning which, may have been a contributing factor to the issues leading to the initial failure. On discussion with the client, it was decided to build up the lower blocks and design and build a tool for machining the pads in-situ.
Once the chipper had been repaired, overhauled, re-painted and fitted back onsite at the customer’s facility, the client was so pleased with Rotec’s workmanship and project management that Rotec have now taken delivery of another unit from the same workshop for a complete overhaul.
The Engineering Managing of the flooring, MDF and OSB manufacturer has since reported that the overhaul and rebalancing of the machine is so good that the company is achieving a higher output rate and saving 10% on the machine’s previous running cost.
Laurence White, Business Development Manager for Rotec Hydraulics Ltd, commented;
