Emergency Release Of The Robot Arm - ABB IRB 120 Product Manual

1.2.5.3 Emergency release of the robot arm

Description
In an emergency situation, the brakes on a robot axis can be released manually
by pushing a brake release button.
How to release the brakes is detailed in the section:
The robot arm may be moved manually on smaller robot models, but larger models
may require using an overhead crane or similar equipment.
Increased injury
Before releasing the brakes, make sure that the weight of the arms does not
increase the pressure on the trapped person, further increasing any injury!
When releasing the holding brakes, the robot axes may move very quickly and
sometimes in unexpected ways.
Make sure no personnel is near or beneath the robot arm.
