Dock levelers are basically an adjustable ramp or bridge designed to drive the lift truck across from the building onto the truck. Incoming trucks are not all the same height; some may be level with the building floor, some above floor height, and some below floor height. If the incoming trucks are always level with the building floor height a 6’ long dock leveler will work just fine. If the trucks are 4”-8” above or below dock height, then an 8’ long dock leveler works much better because the extra platform length decreases the angle of incline or decline. A 6’ long platform would end up with a steeper degree of incline or decline making it more difficult to push a pump truck with a load on it. As standard, Pentalift dock levelers are available in 6’, 8’, 10’ and 12’ lengths. Always consult with the manufacturer for their recommendations based on the specifics of your loading dock area.
