The TR3000 raise boring machine being sent to George Fisher mine.

The TR3000 has a nominal 3m diameter boring size and 400m in depth and a standard 311mm pilot hole diameter.

It has a maximum pilot drilling torque of 78,000 Newton metres, reaming torque of up to 237,000Nm and breakout to 266,000Nm.

The maximum down thrust force is 1600 kilonewtons and up thrust is 4500kN.

Total installed power on the machine is 360 kilowatts.
