The Aluminum truck dock board with steel safety curbs is designed for portability and safety. The deck is made of tough high strength aluminum tread plate. The edges are beveled for smooth entry and exit. Safety curbs are coated yellow and are constructed of steel with cast tapered ends. Steel legs are bolted on for increased durability. Canted locking legs for easier truck portability. Manufactured in compliance with OSHA. The capacity is based upon the heaviest type of equipment used plus the maximum load carried times the single axle rating of total load. Dynamic loading, driver tendencies, speed and frequency of use must be considered. When using three-wheeled fork trucks order dock board with capacity at least four-times the lifting capacity of fork truck. The width of the dock board should be at least fifteen (15) inches wider than the load or equipment passing between the curbs. If the load does not pass between curbs, but is elevated above, add fifteen (15) inches to overall width of equipment.
