Market debut for new borer
16 July 2013Equipment manufacturer Terratec has launched a new rig to join its raise boring product line. The machine, called the Universal Boxhole Boring Machine - UB1000, is designed to boxhole sections up to 1.06m diameter and 100m long. It can also ream conventional raises nominally 1.8m diameter by 200m deep.
Terratec spokesman Kit Lau argued "The machine brings into the market innovative solutions to allow the safe and efficient execution of slots in the mines with a fully automated raise drill.
"The Derrick Assembly, including the gearbox, complete with Floating Drive Box (Chuck), is suitable for 10in diameter by 48in long drill string. The gearbox is designed so it can be positioned with the drive box pointing up for box-holes, or down for conventional raising."
The machine is supplied complete with a gearbox turning cradle suitable to quickly and easily index from box hole mode to raise-bore mode in less than one shift. The integrated torque column/thrust cylinders provide balanced thrust and clear access from all sides.
The rig is able to operate at up to 45 degree dip, either side of centre-line, in a 'cross-drift' orientation, with no requirement to turn the rig first, or any modifications to change from left hand to right hand dip.
Powered overhead worktable doors with integrated powered wrenching system ensure no man access is required at height.
