Design: Mechanical, manually operated torque multiplier for controlled screw tightening. Multiplier and support made of high-quality steel. Equipped with overload protection to safeguard the gearbox. Input drive features an internal square for drive tools such as ratchets, T-handles, and torque wrenches. It is advisable to operate it with a torque wrench to monitor the maximum load capacity of the tools and the screw tightening values. The output drive has an external square for receiving socket inserts (preferably use machine screw inserts due to the high torque). Precise planetary gears ensure accurate torque transmission with long-term accuracy of ±5%. Advantage: Torque multipliers enable the transmission of high torques with correspondingly low lever arms.
