Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) Access to the cage, cab or machine house
						shall be afforded by a fixed ladder, stairs or platform requiring a step-over
						of not more than 12 inches, except in installations prior to January 1, 1973,
						the gap may exceed 12 inches but shall not exceed 20 inches, and so located
						that a person approaching or leaving the crane shall not be exposed to
						dangerous shear hazards. If the top of a ladder or stairway or any position
						thereof is located where a moving part of a crane, such as a revolving house,
						could strike an employee ascending or descending the ladder or stairway, a
						prominent warning sign shall be posted at the foot of the ladder or stairway. A
						system of communication (such as a buzzer or bell) shall be established and
						maintained between the foot of the ladder or stairway and the operator's
						cab.
(b) For bridge and gantry
						cranes, there shall be a ladder, stairs or other safe means which provides
						access to the bridge walkway. Where cage is attached to and below bridge
						girders, no portion of the cage or cage platform shall be in the projected area
						between the girders unless there are bridge stops or bumpers to prevent the
						trolley from passing over the projected area opposite the cage.
(c) On all cranes having revolving cabs or
						machine houses, means shall be provided to permit the operator to enter or
						leave the crane cab or machine house irrespective of position of the cab and to
						safely reach the ground.
(d) When
						necessary to go out on booms or bridges to service the blocks or other parts of
						the machinery, each boom or bridge shall be equipped with a substantial walkway
						or platform handholds, or grab irons giving access to the blocks and machinery.
						Permanent elevated platforms attached to the building at the end of the bridge
						crane runways and at the same level of the bridge, which give safe access to
						the bridge, or mobile work platforms, will be acceptable in lieu of the
						platform on the bridge. Single girder or monorail bridges with underhung
						trolleys and hoists are exempted, provided the hoists and trolleys are serviced
						or repaired from a safe, portable ladder or other safe temporary means. Booms
						which can be and are safely lowered to a safe location for such servicing
						operation will be exempted from this order, provided all grease and oil
						fittings and receptacles are piped or otherwise located so that they can be
						conveniently serviced from such walkways or safe locations without climbing
						over or upon the boom, bridge, or trolley structure. Footwalks shall be of
						rigid construction and designed to sustain a distributed load of at least 50
						pounds per square foot.
(e) Where
						practicable, every overhead traveling crane walkway shall have a headroom of at
						least 78 inches. Where not practicable to provide this clearance, the crane
						walkway shall have at least 60 inches clearance or the walkway shall be omitted
						from the crane and a permanent elevated platform shall be attached to the
						building at the end of the crane runway.
NOTE: See General Industry Safety Orders, Group I for
						  general workspace, and access requirements.
