Quick-Change Wheels for the ROVVER X pipe inspection crawler from Envirosight can be changed quickly, without requiring bolts, washers, or tools. To attach, each wheel is simply pressed onto a locking hub. To detach, the center of the hub is pressed, releasing the wheel. The design streamlines crawler setup and cleaning, and eliminates the risk of loose bolts. Ten wheel options are available: rubber wheels in four sizes, each with a tread pattern that enhances traction and smooth rolling; abrasive wheels in three sizes; and carbide wheels in three sizes. All have optimized geometry for improved clearance centering. 866/936-8476; www.envirosight.com; Booth #1206.
