4. Must an overhead crane be equipped with an emergency stop?
CSA C22.2 No. 33 2019 of the Canadian Electrical Code, Part 1, which is mandatory in Quebec, reads as follows: "In the case of a multiple motor overhead crane, there must be a main contactor to simultaneously shut down all conductors supplying the current required for the crane's movements. The contactor shall be operated by a stop-reset command located near the crane operator's control station. "
- So, an emergency stop is mandatory for the following equipment:
- Overhead crane with electric hoist and motorized trolley and / or motorized overhead crane
- Jib cranes with electric hoist and motorized trolley and / or motorized rotation
- Monorail with electric hoist and motorized trolley
- Gantry crane with electric hoist and motorized trolley and / or motorized movement.
