4.2.2 Emergency Pull-rope Device Installation

This must be a dual-channel NC contact mechanical device, and must have a reset button. The
pull-rope must be able to be triggered from any position.
Install the pull-rope at an accessible height for workers of average height. Installing it too high
results in workers being unable to reach it.
The railing protection is still needed after you install the pull-rope switches. The pull-rope
switches are there so that the emergency stop function can be triggered from any position.
When installing emergency pull-rope devices, place them around the entire safety protection
railing as shown in Figure 4.4.
