Enerpac’s rigid all-steel torque wrench is currently being employed by Mt Thorley Warkworth Mine to enhance safety and efficiency.
According to Enerpac, the bolting technology employs high pressure (700 bar) force to achieve exceptional power-to- weight ratios.
The wrench has been used at the Hunter Valley minesite to ensure correct power, precision and repeatability in loosening and tightening nuts.
According to the manufacturer, unevenly torqued fasteners result in weak spots being built into moving, reciprocating or vibrating equipment, such as engines, tracks, wheels, and this would pose risk management issues to owners and operators.
The wrench weighs 5kg and can provide up to 4330Nm torque.
The wrench model used at Mt Thorley is complemented by a ZU4 208TE-Q 1.25kW electric pump specifically designed for repetitive bolting applications and applications that may require remote pump and valve operation for safety. It utilizes a 1.25 kW universal motor that works well on long extension cords if required, or generator-driven electricity supplies.
The high-efficiency two speed pumps feature higher oil flow and bypass pressure (85 bar) for cooler running that requires 18% less current draw than comparable pumps. A self-priming first stage increases pump performance by supercharging the second stage piston pump, improving oil flow in both hot and cold weather operations. The pumps feature a low-voltage (15 vdc) pendant with sealed switches for remote operation and enhanced operator safety.
