SAFETY

Work Platform Design Requirements

(Per ANSI/ITSDF B56.6 - 2016, Sec. 8.24)

1. A structural safety factor for the personnel work platform of not less than 2:1 for ductile materials (based on minimum yield strength) and 5:1 for non-ductile materials (based on minimum ultimate strength) used for all load supporting structural elements and personnel work platform attachment means.

2. The personnel work platform shall have a floor with a slip resistant and self-draining surface. Any opening in the floor or between the floor and the toe board shall be dimensioned so as to prevent the passage of a 15 mm (.59 inches) diameter sphere. Trap doors in the floor of the personnel work platform are not permitted.

3. If the distance from ground level to the floor of the personnel work platform exceeds 400 mm (15.75 inches), the personnel work platform shall be equipped with an access ladder. This distance shall be determined when the rough terrain forklift truck is on a level surface, and the personnel work platform is in the fully lowered position on the lifting means. The steps or rungs of the ladder, and the handholds or handrails of the ladder shall conform to the requirements of ISO 2867. The ladder shall align with the access opening to the personnel work platform.

4. The personnel work platform shall not allow any portion of the fork tips with which the personnel work platform is intended to be used to protrude beyond any part of the personnel work platform.

5. The minimum space required for each person allowed on the personnel work platform as stated on the personnel work platform nameplate shall not be less than 500 mm x 500 mm (19.68 x 19.68 inches).

6. Personnel work platforms may utilize movable sections to extend the length of the platform perpendicular to the longitudinal center plane of the truck. Personnel work platforms with movable sections may have a different capacity for the plat- form when the movable sections are in the retracted and extended positions. Both capacities shall be clearly indicated on the personnel work platform nameplate. The rough terrain forklift truck information plate(s) or load capacity chart shall indicate the rated capacities for the personnel work platform with the movable sections in both extended and retracted.

7. A toe board with a minimum height from the platform floor of 150 mm (5.90 inches) shall be provided around the perimeter of the personnel work platform. At points of access to the personnel work platform the height of the toe boards may be reduced to 100 mm (3.94 inches). Toe boards may be attached to gates and removable guardrails.

8. Means shall be provided to prevent a side tilt attachment from tilting laterally when the personnel work platform is installed. Personnel work platforms, whether fitted to the forks or a quick interchange device, shall not be equipped with a side tilt device.

9. Means shall be provided to: a. securely retain the personnel work platform against the vertical face of the forks or carriage (fork mounted), or b. securely attach the personnel work platform to the lifting mechanism (quick interchange mounted).

10. The personnel work platform shall be provided with restraining means for personnel on the personnel work platform. Personnel work platforms equipped with movable sections shall meet the same restraining requirements. The restraining means shall consist of either a guardrail enclosing the entire perimeter of the personnel work platform, or a guardrail enclosing all but the side of the personnel work platform that faces the intended work area. A permanent guardrail or similar structure shall be provided on the side closest to the lifting mechanism. The lanyard anchorage points shall only be provided on the permanent part of the personnel work platform structure.
