No. 659980 size 2000 + 6000 available on request with electronic measured value sensors. Torque multiplier Mechanical manual torque multiplier for controlled screw tightening. Multiplier and support of high-quality steel. With overload shut-off to protect the transmission. Input drive with internal square socket for drive tools such as a ratchet,T-handle, torque wrench. It is sensible to operate the device with a torque wrench, so that the maximum load and the screw torque values can be checked. Output drive with external square for holding sockets (preferably use impact sockets due to the high torques). 65 9975 - Precise planetary transmissions guarantee exact torque transfer with long-term accuracy of ±5 %., with overload protection. 65 9980 - Extremely precisely machined transmissions with ground gears and honed bores guarantee exact and consistently reproducible torque multiplication. Unique accuracy of not less than ±4 %. Very compact and lightweight design, exceptionally long working life, and low maintenance. Advantage: Torque multipliers allow the transmission of higher torques with a correspondingly shorter lever arm. 65 9980_1300 / _2700 Output torque2500 Nm 0.84 revolutions Operating principle Torque multiplier. At a stated transmission ratio of 1:25,25revolutions at the input (and 0.84 revolutions at the output) are necessary to convert an input torque of 100 Nm into an output torque of2500 Nm. 25 revolutions Input torque 100 Nm applied using a torque wrench. 65 9975_2000 65 9980_6000
