KUKA LBR class-A/B power wrench

The KUKA LBR class-A/B power wrench is an optimal addition to the LBR iiwa. It can be integrated quickly and easily into existing production systems. In this way you have at your disposal the ideal power wrench for safety-critical screwed connections requiring documentation. 

Flexible screw-fastening solutions with the KUKA LBR class-A/B power wrench

With the class-A/B power wrench, you can expand the range of potential applications for the KUKA LBR iiwa. Manual screw-fastening processes are automated by the end effector. We have designed the right power wrench for every type of screw fastening. 

  • KUKA LBR class-A/B power wrench: for safety-critical screwed connections of class A requiring documentation and for function-critical screwed connections of class B.
  • KUKA LBR class-C power wrench: screw fastening class C for simple screwed connections where a “Go/No Go” evaluation is sufficient.

KUKA LBR class-A/B power wrench: your advantages

  • The power wrench is suitable for all common screw-fastening applications – including those involving high torques.
  • The screw-fastening operation can also be carried out in several stages.
  • The class-A/B power wrench operates in clockwise and counterclockwise direction.
  • The power wrench can be integrated quickly and easily into existing production systems.
  • The mechanical system is optimally designed for tactile calibration by the robot.
  • The standard interface on the angle head is used for connecting additional components, such as protective sleeves and screw tip safeguards.
  • Thanks to the wrench controller integrated into Sunrise.OS, we can accommodate your requirements for the transmission and logging of screw-fastening data on a project-specific basis.

Work without safety fences with the KUKA LBR class-A/B power wrench

Our class-A/B power wrench can be perfectly integrated into operations with human-robot collaborationThis is enabled by the following functions: 

  • Automatic energy coupling and integrated energy supply
    When the tool is mounted, energy coupling is carried out automatically. The energy supply is integrated – with no external lines and thus no disruptive forces.
  • HRC-capable and safe
    The design is rounded and thus HRC-capable. In the event of a collision or Emergency Stop, the power wrench automatically switches itself off immediately. No pinching or crushing points are present on the power wrench.
