For high torque with minimal effort; use with torque wrench; roller-bearing-mounted planetary gear with low, compensated friction losses therefore precise compliance with the multiplication ratio. Guaranteed accuracy better than ± 4%. Each multiplier is supplied with its own unique calibration certificate allowing the accurate calibration of input torque for critical application. Calibrated from 20% of maximum capacity. Models up to 47 500 Nm and torque multiplier with pneumatic motor available upon request.
