Tower cranes

When erecting tower cranes, dozens of heavy bolts must be tightened to relatively high torques. To guarantee the stability of the crane when lifting loads and to minimize wind influences accuracy is very important. And when disassembling the crane, these bolts must also be loosened again.

A battery torque wrench is the ideal tool which prevent having to work with hoses and cords and slow and heavy machines high up in the crane. Radial supplies various types of RAD battery torque wrenches that are very suitable for this job. The MB-RAD LIEBHERR series are certified by Liebherr.

Testimonial

A mechanic from a well-known tower crane assembly and dismantling company:

“Thanks to the battery-operated B-RAD torque wrench, we can accurately torque all bolts without hydraulic hoses getting in the way, and we no longer suffer from the loud noise and vibration of impact wrenches. Another big advantage is that we can simply loosen the bolts that were previously tightened with the RAD.”

Backup wrenches

A backup wrench will prevent rotation of the bolt or stud when the nut is being tightened. A back-up wrench prevents the bolt from rotating during torquing. During the tightening of the bolt , the back-up wrench does not have to be held by hand, which increases safety. Although the backup wrench will be locked in place after tightening, it can be easily removed by loosening the small hex bolt. Compared to a manual method, this variant is many times safer, especially when working at higher torques.
