Norbar HT 6/125 AWUR Manual Torque Multipliers 340-3400NM, Output Square: 1 1/2", Input Square: 1/2"
The Norbar HandTorque HT-6/125 AWUR is a manual torque multiplier designed to deliver up to 3,400 N·m, with a 1/2" square input, 1-1/2" square output and torque multiplication accuracy better than ±4%. Its nominal 125:1 multiplication ratio allows a suitable low-torque input wrench to produce high output torque, while the anti-wind-up ratchet (AWUR) helps control stored energy in the gear train. Supplied by General Tech Services LLC, UAE, it is suitable for demanding industrial bolting applications without an external power source.

Part No. 16093
The Norbar HT-6/125 AWUR is designed for heavy bolting tasks requiring output torque between 340 and 3,400 N·m. Its multi-stage epicyclic gearbox multiplies the input torque from a standard torque wrench, making it useful when high output torque is required from a relatively low input.
The multiplier has a nominal torque multiplication ratio of 125:1. Norbar specifies the true torque multiplication ratio rather than the velocity ratio, so confirm the exact mean torque ratio from the manufacturer's documentation before calculating input settings for critical joints.
The tool accepts a 1/2" square-drive torque wrench and provides a 1-1/2" square output. Its manual operation means it requires no electricity, compressed air or battery, making it suitable for offshore facilities, remote substations, confined vessels and field maintenance locations.
The anti-wind-up ratchet helps retain stored energy in the gear train when the input wrench is released, reducing the risk of sudden kickback and making repositioning easier between tightening operations. For a lower multiplication ratio, consider the Norbar HT-6/25 AWUR, which has a nominal 25:1 ratio.

Who This Product Is Best For
-
Maintenance teams handling fasteners requiring up to 3,400 N·m.
-
Offshore, oil and gas, and petrochemical facilities where powered tools may be restricted.
-
Industrial technicians who need a portable, manual high-torque solution.
-
Workshops with a suitable 1/2" torque wrench that need significantly higher output torque.
-
Operators who want the additional control provided by an anti-wind-up ratchet.
How to Use It
-
Identify the required output torque and confirm the multiplier's exact mean torque ratio using the manufacturer's documentation.
-
Calculate the required input torque using the verified ratio.
-
Set a suitable 1/2" square-drive torque wrench to the calculated input value.
-
Attach the torque wrench to the multiplier's input and fit the correct socket to the 1-1/2" output.
-
Position the reaction arm against a suitable, secure reaction point according to the manufacturer's instructions.
-
Apply force smoothly and confirm that the tightening cycle has completed as intended.
-
Release and reposition the tool safely before continuing with another fastener.
Always follow the manufacturer's operating instructions and the applicable bolting procedure. Do not assume the nominal 125:1 ratio is the exact torque ratio when tightening critical joints.
Frequently Asked Questions
1. What is the maximum output torque of the Norbar HT-6/125 AWUR?
It delivers up to 3,400 N·m, with a listed working range of 340–3,400 N·m.
2. What is the torque multiplication ratio?
The nominal ratio is 125:1. Confirm the exact mean torque ratio in the manufacturer's documentation before calculating input torque for critical applications.
3. How accurate is the HT-6/125 AWUR?
Its torque multiplication accuracy is specified as better than ±4%.
4. What does AWUR mean?
AWUR stands for anti-wind-up ratchet. This mechanism helps retain stored energy in the gear train when the input wrench is released, reducing the risk of sudden kickback.
5. What input and output drive sizes does it use?
It has a 1/2" square input and a 1-1/2" square output.
6. Does this torque multiplier require a power supply?
No. It is manually operated and requires no electricity, compressed air or battery.
7. What is the difference between the HT-6/125 AWUR and HT-6/25 AWUR?
The HT-6/125 AWUR has a nominal 125:1 multiplication ratio, while the HT-6/25 AWUR has a nominal 25:1 ratio. Choose based on the required output torque and the input wrench available, verifying the exact torque ratio for the selected model.
