Norbar HT 9/25 AWUR Manual Torque Multipliers 950-9500NM, Output Square: 1 1/2",Input Square: 3/4"
The Norbar HandTorque HT-9/25 AWUR is a manual torque multiplier designed to deliver up to 9,500 N·m through a 1-1/2" output drive. With a nominal 25:1 multiplication ratio, torque multiplication accuracy better than ±4%, and an anti-wind-up ratchet (AWUR), it supports controlled heavy-duty bolting while helping manage stored energy in the gearbox. Supplied by General Tech Services LLC, UAE, it requires no external power source.

Part No. 16070
The Norbar HT-9/25 AWUR is designed for demanding industrial bolting applications that require high output torque and controlled operation. Its multi-stage epicyclic gearbox converts input torque from a compatible torque wrench into a much higher output, making it suitable for heavy maintenance and assembly tasks.
The nominal torque multiplication ratio is 25:1, and the listed working range is 950–9,500 N·m. Norbar specifies the true torque multiplication ratio, so confirm the exact mean torque ratio before calculating input settings for critical joints.
This model accepts a 3/4" square-drive torque wrench and drives a 1-1/2" square-drive socket. Its manual operation makes it useful at remote sites and locations where pneumatic or powered tools are impractical.
The anti-wind-up ratchet helps control the stored energy in the gear train and reduces the risk of the input wrench kicking back when released. Follow the manufacturer's instructions for operation, reaction-arm positioning and controlled release.
If you do not require the anti-wind-up ratchet, compare this model with the standard Norbar HT-9/25, Part No. 16059.

Frequently Asked Questions
What is the maximum output torque of the HT-9/25 AWUR?
It delivers up to 9,500 N·m, with a listed working range of 950–9,500 N·m.
What is the multiplication ratio?
The nominal torque multiplication ratio is 25:1. Confirm the exact mean torque ratio before setting input torque for critical joints.
How accurate is the Norbar HT-9/25 AWUR?
Its stated torque multiplication accuracy is better than ±4%.
What does AWUR mean?
AWUR stands for anti-wind-up ratchet. This mechanism helps control stored energy in the gearbox and reduces the risk of the input wrench kicking back when released.
What are the input and output drive sizes?
The tool accepts a 3/4" square-drive torque wrench and has a 1-1/2" square output drive.
Should I choose the HT-9/25 AWUR or the standard HT-9/25?
Choose the HT-9/25 AWUR if you need the anti-wind-up ratchet feature. The standard HT-9/25, Part No. 16059, is the alternative without AWUR. Consider your application and operating requirements before ordering.
