Manual Backup Wrenches

You place the Back-Up Wrench on the counter-nut, tighten the nut with a torque wrench and then take off the Back-Up Wrench from the counter-nut, very simply and safely. As the Back-Up Wrench releases so easily, there is no need for a hammer. The speed of work will increase rapidly in comparison to a slogging wrench. When tightening the nut, you can keep your hands away from the backup wrench and the tool, so that they cannot get pinched.

Torque Gun has two models:

Back Up Wrench Interchangeable spanners from 30mm to 80mm (max. 5,400 Nm)	Mechanical / Manual Back Up Wrench Sizes of 36mm to 95mm (max. 9,500 Nm)

Advantages:

• Counter-nut does not rotate with the nut; easy and fast
• No chance of getting hands caught any more (working hands-free)
• No hammer necessary for removing the backup wrench
• Work faster than with a slogging wrench and hammer
• No dangerous situations with slogging wrenches and hammers any more!
