Advanced Torque Products (Berlin, CT) offers the ATP 40000 mechanical torque multiplier, a digitally controlled wrench that produces up to 40,000 ft/lbs. The device employs all-mechanical operation, which eliminates the need for heavy pumps, tubes, and bleed-off. Mechanical gears rotate on needle roller bearings with hardened and ground journal pins. An anti-rotation device holds torque without backing off. A Smartchip and electronic bridge circuit in the wrench’s outer casing provide traceability and permit any control box to be used with the calibrated hub. An EPROM within the wrench stores calibration data.

The digital controller is equipped with peak and track mode, and an over-torque alarm. Interchangeable mounting and radio transmitter options permit control and operation. The unit has up to eight programmable scales in ft-lbs, in-lbs, N-m, Kg-cm, or other custom units.
