Norbar HT 9/125 AWUR Manual Torque Multipliers 950-9500NM, Output Square: 1 1/2", Input Square: 1/2"
The Norbar HandTorque HT-9/125 AWUR is a manual torque multiplier delivering up to 9,500 N·m, with a 1/2" input drive, a 1-1/2" output drive and torque multiplication accuracy better than ±4%. Its anti-wind-up ratchet (AWUR) helps control stored energy in the gear train during tightening. No power supply is required. Supplied by General Tech Services LLC, UAE.

Part No. 16071
The Norbar HT-9/125 AWUR covers a torque range of 950–9,500 N·m, making it suitable for heavy-duty bolting and maintenance applications. Its high multiplication ratio allows a compatible torque wrench with a relatively low input torque capacity to deliver much higher output torque.
The HandTorque range uses multi-stage epicyclic gearing to multiply the input torque. The HT-9/125 AWUR has a nominal multiplication ratio of 125:1. For critical bolted joints, confirm the exact mean torque ratio from the manufacturer's documentation before calculating the input setting.
With a 1/2" square input and a 1-1/2" square output, this model can be used with compatible torque wrenches and sockets. Its manual operation makes it suitable for remote maintenance locations, offshore facilities, industrial plants and other sites where powered tools may be impractical.
The anti-wind-up ratchet helps control the stored energy released by the gear train when the input wrench is unloaded. This can reduce the risk of sudden wrench movement and assist with repositioning between tightening operations.
For applications requiring greater output capacity, compare the HT-9/125 AWUR with the Norbar HT-11/125 AWUR and confirm the appropriate model for your required torque range.
