Current through Register Vol. 63, No. 7, July 1, 2024
(1) Overhead Guards.
(a) Where a rider type lift truck operator is
			 exposed to hoisted objects that might fall, or stacked objects that might be
			 dislodged and fall, the truck shall be equipped with an overhead guard. The
			 guard shall be of sufficient strength to support impact load tests as specified
			 in Table OR-N-1: [Table not included. See ED. NOTE.]
(b) Impact load tests shall be conducted with
			 the guard in place on a vehicle for which it is designed or on a simulated
			 mounting. Running gear need not be in place. The load shall be dropped in free
			 fall from an appropriate height so that the impact is centered approximately
			 above the driver's position. Test loads shall have a length equal to or greater
			 than the width of the guard, and shall strike the canopy at right angles to the
			 vehicle frame.
(c) Guards of a
			 design which has been so tested shall be identified by a metal tag permanently
			 attached to the canopy in a position where it may be easily read from the
			 ground. This tag shall be permanently and clearly marked with the impact test
			 load, expressed in foot-pounds to which guards of the same design have been
			 tested.
Note:
Guards required by OAR
				437-002-0227(1)
				(a) through (c), or by the rules following,
				are not intended to withstand the impact of a capacity load falling from any
				height.
(d) Guards which
			 are not of a design which has been tested in accordance with OAR
			 437-002-0227(1)(a)
			 through (c)  of this rule, may be constructed
			 of material as specified in Table OR-N-2 or material of equivalent strength:
			 [Table not included. See ED. NOTE.]
(e) The construction of canopy guards are
			 built in compliance with OAR
			 437-002-0227(1)(d)
 
			 shall be based on the strength of four upright members. Guards constructed with
			 less than four upright members shall be of equivalent strength.
(A) Canopy type overhead guard frames shall
			 be braced to overhead members on each side of the frame to provide structural
			 rigidity both longitudinally and transversely.
(B) All guard mountings or attaching brackets
			 shall be constructed and secured to the vehicle in a manner to provide adequate
			 support to the upright members of the canopy type overhead guard.
(C) Cantilever overhead guards shall be of
			 equivalent strength.
(f) Guards shall be constructed in a manner
			 that does not interfere with good visibility, but openings in the top shall not
			 exceed 6 inches in one of the two dimensions, width or length. Guards shall be
			 large enough to extend over the operator under all normal circumstances of
			 operation, including forward tilt.
(A)
			 Provisions shall be made so that failure of the mast-tilting mechanism will not
			 allow the overhead guard to cause injury to the operator.
(B) Lift trucks operated by seated operators
			 shall have not less than 39 inches of clear vertical space between the
			 operator's seat when depressed and the underside of the guard. Lift trucks
			 operated by standing operators shall have not less than 74 inches of clear
			 vertical space between the platform and the underside of the guard.
Note:
Where overall height of truck with forks in
				lowered position is limited by head room conditions and there is insufficient
				space for vertical clearance or for the operator to assume a normal driving
				position, normal overhead guard heights may be reduced, or the overhead guard
				may be omitted. The height and stability of stacks of piled material, the
				weight of individual units handled, and the operating space available shall be
				such as will provide reasonable safety for the operator if it is necessary to
				remove the overhead guard.
