Safety

13 Emergency Release of Mechanical Arm

If an emergency situation occur where a person is trapped by the mechanical robot arm,
the brake release buttons should be pressed whereby the arms can be moved to release
the person. To move the arms by manpower is normally possible on the smaller robots
(1400 and 2400), but for the bigger ones it might not be possible without a mechanical
lifting device, like an overhead crane.
If power is not available the brakes are applied, and therefore manpower might not be
sufficient for any robot.
Before releasing the brakes, be sure that the weight of the arms does not enhance
the pressure on the trapped person.

14 Limitation of Liability

The above information regarding safety must not be construed as a warranty by
ABB Robotics that the industrial robot will not cause injury or damage even if all safety
instructions have been complied with.
