Faster…Safer…Wiser. The Wave Work Assist Vehicle is a revolutionary concept designed by Crown to help you work faster, safer and wiser. The Wave works efficiently and quietly in almost any indoor application; elevates a person and a load (one normally carried by hand) up to effective work heights of seventeen feet; travels nearly twice as fast as the average walking speed; navigates easily in the tightest spaces; and turns within its own radius. The Wave vehicle replaces the need for rolling ladders and warehouse ladders typically used in warehouse and maintenance applications.
