ISO 1000 TORQUE LOADING RIG 

INTRODUCTION_____________________________________________________________ 

The Norbar ISO 1000 torque loading rig with 90° rotation is designed to test torque wrenches up to a 

maximum capacity of 1000 lbf.ft or 1350 N.m. 

Any wrench within the systems maximum capacity can be tested in both the horizontal and vertical 

planes, so allowing for a more accurate simulation of how the tool is actually used in the field. 

To measure the applied torque a torque transducer coupled to an appropriate measurement 

instrument are required. 

The loading rig can also be used to carry out torque tests on conventional spanners, wrenches and 

wrench extensions to their appropriate standard. With accessories the rig can also be used for 

checking tensiometer instruments for wire ropes and similar cables. 

Other ISO torque loading rigs available include: 

1. ISO 2000 N.m for testing at greater capacity. (Model No. 20502) 

2. Rate controlled ISO 1000 lbf.ft for applying torque at a set rate. (Model No. 60119)

MACHINE INSTALLATION 

1. Locate the ISO machine on sturdy bench. 

2. Slide the rotating lever in from the back and secure with the 2 circlips provided (see drawing on 

page 5). 

3. Slide tool reaction post on to main beam. 

HORIZONTAL TO VERTICAL OPERATION 

1. The machine is shipped in the horizontal mounting position. 

To change to vertical position: 

2. Release the orientation release clamp by pushing it away to the extended position. (see drawing 

on page 5) 

3. Grip the rotating lever and gently pull to rotate the machine 90 degrees 

4. Reclamp the mechanism by pulling the orientation release clamp towards yourself. 

5. The rig is ready for vertical use. 

TRANSDUCER AND INSTRUMENT INSTALLATION 

1. Select the lowest capacity torque transducer to cover the wrench to be tested. 

2. Mount the male square of the transducer into the female square of the gear box, use adaptors 

to suit. 

3. The appropriate locating collar should be placed over the top of the transducer and locked by 

rotating through 90 degrees. 

4. Connect a transducer lead from the transducer to the instrument. 

5. Ensure the instrument functions correctly. (If in doubt see operators manual).

WRENCH INSTALLATION 

1. Slide the reaction post assembly to the far right of the reaction bar. This will allow the operator 

to index a ratchet wrench for insertion into the torque transducer. 

2. With the handle of the wrench running along the length of the rig, mount the torque wrench to 

be tested in the female square of the transducer. 

3. To adjust the reaction assembly slacken the clamp at the rear of the assembly. Move the post 

up and down to alter the height, and slide the assembly along the arm to adjust the lateral 

position. 

4. The ideal wrench orientation is horizontal with the bobbins reacting against the normal hand 

position, this is usually the centre of the wrench hand grip. 

NOTE: 

See drawing on page 5 for details. 

Wrench handle should be mounted under the wire strap for safe operation in horizontal or 

vertical operation. 

ITEMS OF NOTE 

1. The gear box makes movement in the output drive difficult to detect. Use the 'A' and 'B' arrows 

on the hand wheel and gearbox output as an indication. 

ie:- 'A' indicates direction to apply force. 

'B' indicates direction to release force. 

2. Always ensure the 90° clamp is locked before loading the rig. 

3. In the case of a ratchet wrench, with push through square drives, it is important to ensure the 

square is operating on the correct side of the ratchet. 

4. When rotating the machine, ensure the transducer lead is not caught up in the mechanism.
