Current through Register Vol. 54, No. 28, July 13, 2024
(a)
Changing truck wheels.
Platforms shall be provided for
					 changing and repairing truck wheels on end trucks.
(b)
Access to crane cages.
A
					 platform or footwalk shall be located on the crane or crane runway to give
					 access to the crane cage, and it shall be accessible from one or more stairways
					 or fixed ladders. This platform or footwalk may be not less than 18 inches
					 wide.
(c)
Stairways and
					 ladders.
When stairways are used to give access to platforms they
					 shall make an angle of not more than 50° with the horizontal and shall be
					 equipped with substantial railing. If ladders are used to give access to
					 platforms, they may extend not less than 36 inches above the platform. Railed
					 stairways or ladders used as means of ingress and egress to crane cages shall
					 be located so as to prevent the operator or other persons from coming into
					 contact with live lines feeding runway or other parts of the crane
					 equipment.
(d)
Footwalks-clearances.
A footwalk shall be placed along the
					 entire length of the bridge on the motor side, and a short platform twice the
					 length of the trolley placed at one end of the girder on the opposite side,
					 with a vertical clearance of at least 6 feet 6 inches when the design of the
					 crane or building permits, but in no case shall there be less than 4 feet
					 clearance. For hand operated cranes, the footwalk may not be required to be
					 installed on the bridge of the crane, but there shall be a repair platform,
					 equal in strength and design to that required for motor operated cranes,
					 installed on the wall of the building or supported by the crane runway at a
					 height equal to the lower edge of the bridge girder to facilitate necessary
					 repairs.
(e)
Width of
					 footwalks.
Clear width of footwalks shall be not less than 18 inches
					 except around the bridge motor where it may be reduced to 15 inches.
(f)
Construction.
Footwalks
					 for outside service shall be constructed so as to provide proper drainage, but
					 the openings between the boards, sections of metal decking or floor plates
					 shall not be wider than 1/4 inch.
(g)
Railings and toeboards.
Railings and toeboards shall conform with the following:
(1) Railings shall be capable of safely
					 sustaining a vertical load of 80 pounds per linear foot and a horizontal thrust
					 of 25 pounds per linear foot.
(2)
					 The suggested inside diameter for pipe railings may not be less than 1 1/4
					 inches.
(3) Railings may be not
					 less than 42 inches in height, with an additional rail midway between the top
					 rail and the floor.
(4) Pipe
					 railings may be not less than 1 1/4 inches inside diameter if of iron or be not
					 less than 1 1/2 inches outside diameter if of brass tubing.
(5) Posts or uprights shall be spaced not
					 more than 8 feet center to center.
(6) Toeboards shall be not less than 6 inches
					 in height.
(7) Toeboards shall be
					 constructed so as to be permanent and made of metal, wood or other substantial
					 material. If made of wood, toeboards shall be at least equal in cross section
					 to 1 inch by 6 inches; if made of steel at least 1/8 inch by 6 inches; and if
					 made of other construction at least equal to the requirements for steel.
					 Perforations up to 1/2 inch are permissible in metal toeboards.
