So well regarded is Parnis Manufacturing’s reputation in manufacturing and refurbishing mine winders, that the company recently delivered a 23 tonne, 3 metre single drum winder to a gold mining company in Canada.
The unit will be used as a man winder and service hoist, and will be used to reach a depth of 2 000 metres. Manufacturing the winder using material that is safety critical, Parnis Manufacturing’s contribution was to profile and roll, fabricate and weld, inspect, machine and paint – among other specialist services.
“We work from drawings supplied by our customers, first inspecting the material to ensure that it complies with the specifications, and then preparing it for welding. This is essential to ensure an optimum quality result,” says Brian Berry, works manager at Parnis Manufacturing. “A critical element in the fabrication of the winder drum is our specialised welding and boilermaking skills.
“Winder manufacture is certainly a complex engineering task, with the final product comprising a drum, two brake carriers and two brake discs, as well as a shaft, gear box, couplings, bearings and bearing bases,” he adds.
Brian highlights the depth of expertise in mine winder fabrication and refurbishment which continues to reside in South Africa, and emphasises the value of close communication with the customers during construction, to ensure that the final quality product is perfectly to specification.
Parnis Manufacturing tackles not only new winders, but also has an established track record for the repair and complete refurbishment of mine winders.
