A cab-operated crane is an overhead or gantry crane controlled by an operator
in a cab located on the bridge or trolley. The general arrangement of the cab and the
location of control and protective equipment shall be such that all operating handles are
within convenient reach of the operator when facing the area to be served by the load
hook, or while facing the direction of travel of the cab. The arrangement shall allow a
full view of the load hook in all positions. The access to all cab-operated cranes shall
be checked thoroughly.
Serious injuries have occurred as a result of the following conditions:
- Conveniently placed fixed
ladders, stairs, or platforms
provided to reach the cab or bridge
footwalk were not in place. It is unacceptable and poses a significant hazard to allow
employees to board a crane via climbing over guardrails,
over, under, and around building structures, energized hot rails, portable
ladders, or movable platforms
A gap exceeding 12 inches existed between a fixed ladder, stairs or platform, and access
to the cab or bridge footwalk
The fixed ladder used as access to the crane did not meet the American National Standard
Safety Code for Fixed Ladders, ANSI A14.3-1956.
