ABSTRACT:
A method for shaking vehicles comprising driving them over a series of appropriately spaced-apart, mutually parallel bars to vigorously shake the wheels, undercarriage, and body to free them of dirt, gravel and debris. The apparatus provides bars with the appropriate spacing secured to a frame that is sized to be manipulated by hand by construction workers. A track comprises a frame and the spaced-apart bars attached to the frame. Tracks are flexibly connected end-to-end to form rows and rows are laid in a spaced-apart, mutually parallel configuration to form a shaker that will receive the vehicle to be shaken. The shaker may be deployed onto a bed of aggregate that is sufficiently coarse and open-graded to allow the fallen dirt to sift or be washed through the bed of aggregate. The aggregate may also assist in holding the shaker in place and may provide ramps at the ends of each row.
