Sumitomo Paramax drives for Wilpinjong coal mine

Tony Taylor, General Manager, Sumitomo Drive Technologies Australia

Sumitomo Drive Technologies, Australia, recently supplied complete drive packages to be installed at the Wilpinjong Coal Mine Site located North East of Mudgee in NSW. The team responsible for both the design and installation of infrastructure is made up of a joint venture between Theiss and Sedgeman. Sumitomo Drive Technologies ( delivered eight complete drive packages ranging in size from 45kW to 280kW for use on the conveyor systems.

All drive packages were assembled on specially designed base plates, and are complete with motors, fluid couplings or grid type couplings on the reducer inputs, shrink disc rigid couplings on the outputs and all guards. After workshop assembly all were laser aligned and subjected to a no load test run using Sumitomo Drive Technologies' purpose built test rig before final inspection and delivery to the site. Sumitomo Drive Technologies' Managing Director, Steve Wightman said, "We are delighted to be awarded the supply contract for this Greenfield Mine Site project. This is the first time we have worked with Thiess Sedgeman and look forward to a long association with both companies." He added, “We believe our success in this instance is due to our promotion of quality power transmission products and ability to customize those products to our clients' needs.”

The Paramax range is one of the most comprehensive available on today's market, comprising 26 standard frame sizes, all available in a number of configurations as well as a specially designed cooling tower fan drive. Parallel offset or right angle types with solid or hollow output shafts are available. Additions such as Labyrinth or taconite sealing, backstop options and if noise emission is a problem, the option of precision ground bevel sets on the high speed reducer inputs will drastically reduce the noise levels.

Sumitomo Drive Technologies ( is one of the world's largest gear manufacturers. It offers a range of reducers and gear motors for all applications, and its `Seisa Gear division' has the ability to engineer special design gear reducers or speed increasers up to 10,000 kW.
