DRIVEHEADS

The modular drive frame enables installation of drive components on an as-needed basis, allowing for reduced inventory of equipment, and is particularly suited to underground mining. Single, dual and multiple drive configurations are available for host and tripper drive applications using common modular components. Larger, application specific driveheads are available for high powered drift conveyors, portable (shiftable) conveyors and tail drives with or without braking systems and/or flywheels for improved dynamic control during power loss conditions.

TRIPPER DRIVEHEADS

The tripper drive was originally developed by NEPEAN Conveyors to permit existing underground conveyors to be lengthened and allow additional power installation without replacing and upgrading to higher strength belts, or the need for multiple flight conveyors. By placing an intermediate tripper style drive on the carry side and adopting load sharing control methods, peak operating tensions were limited, allowing longer conveyors and ultimately reduced development costs for mine operators. Specialised designs available include low seam height designs, dewatering trippers, tramp iron trippers and trippers incorporating sizing stations. VVVF drives are becoming increasingly popular since first introduced by NEPEAN Conveyors into the underground market over 12 years ago, however still provide many installations with CST, BOSS or Voith controlled fill fluid coupling drive technology.

JIFFY, NIFTY & HEFTY DRIVES

Designed to be a neat, rapidly installed and transportable package, the Jiffy drive combines an extendable delivery jib, impact plate, 75kW drive module and loop take-up all in one. Complete with wheels and tow hitch, they are designed for towing even in the confines of underground mining operations, and are available to suit 1200 and 1350mm belt. NEPEAN Conveyors can customise the Jiffy drive to suit individual customer requirements. Every Jiffy drive is flameproof for use anywhere in mining and minerals environments, although non-Exd units are available on request.

Following the success of the Jiffy Drive, customers demanded an even more powerful all-in-one transportable conveyor package, with even greater take-up capacity – and thus the Nifty drive was developed. Installed power is increased to 150kW, with 20m of take-up capacity to permit all of the installed power to be used. A split version is also available for increased take-up capacity as required. A variety of options are available such as impact plates, belt cleaners and fines management.

Available for hire or purchase, the complete unit is transportable in a single unit allowing rapid relocation and installation.
