The global tower crane manufacturer LIEBHERR has approved the battery-operated torque wrenches of the MB-RAD series for tower crane assembly. This opens up new technical possibilities for the assembly companies to quickly and safely assemble the bolted connections.
After extensive machine capability analysis and EMC tests of the torque wrenches in the torque range of 140-7.000 Nm, the LIEBHERR standard “Technical Information” now also includes the Battery MB-RAD Series torque wrenches. The use of non-approved torque wrenches for towercrane assembly is not permitted.
Secure bolted connections on tower cranes
The MB-RAD has a torque repeatability of 3 % and can be used reliably at ambient temperatures down to -20 °C without warming up. Thanks to the brushless electric motor, torque/angle controlled shut-off and limit value monitoring, the MB-RAD works extremely precisely and is a lot faster than any hydraulic torque wrench.
The MB-RAD Series torque wrenches can optionally be equipped with data logging or a torque check function for maintenance work.
MB-RAD Features:
- Brushless motor technology
- Torque + angle limits
- Bluetooth connectivity
- Bolt counter
- Torque control in anticlockwise rotation
- Multi-user level password protection
- Automatic reaction arm release
- Selectable menu languages
- Intelligent counter for life cycle and maintenance
- Repeatability +/- 3%
- Extremely low noise level – only 65 dB
