Tractor-Mounted Air Drill TQZ-260
The larger of the two tractor-mounted air drills: 260 metres of depth instead of 200, 50 hp instead of 40. Hole diameter stays at 130 to 254 millimetres, weight rises to 4000 kilograms.
Two hydraulic motors drive the rotary head, with infinitely variable speed control. Maximum torque is 4000 to 4700 newton metres, roughly 500 newton metres above the smaller machine. Lifting capacity rises as well, from 12 to 15 tonnes.
The tractor chassis makes the rig self-propelled between boreholes. It measures 3800 by 1700 by 2700 millimetres. Air pressure and consumption match the TQZ-200: 1.7 to 2.5 MPa and 17 to 31 cubic metres per minute.
