Yard ramps usually perform one of two functions: (1) They allow forklifts or other equipment to load a truck trailer from the ground, or (2) they allow loading and unloading from the ground level to a dock. For many operations, where truck access to dock doors is impossible or impractical, yard ramps create flexibility. Loads can be deposited at the ground level, and left there until they can be dealt with. Loads can be staged outside the dock area and then picked up by truck later, using the yard ramp. Yard ramps are excellent for many loading/unloading issues.
