Rapid Repair of Giant Mill Gearbox

A large mill gearbox required urgent rectification following the failure of a key bearing.

Response time during this project was critical, as the vertical gearbox was key to the operation of a large mill.

Repair is not a straightforward engineering challenge when the gearbox measures 3m x 3m x 2m and weighs 51 tonnes!

Somewhere deep inside the mechanism the bearing had failed. Our team of industry experts carried out a complete strip down of the gearbox, followed by a detailed inspection to identify faults. Following assessment of the bearings, defective items were replaced, and the gearbox was rebuilt – ready for entry back into service.

With teams working round the clock, the whole process took less than 2 weeks. “The project is a good example of our exceptionally skilled teams here at Tinsley Bridge and shows the capability to tackle refurbishment of very large pieces of complex, high precision equipment quickly, restoring them to as new condition.”
