This wheel was developed to facilitate the transportation of heavy loads. Thanks to the crowned wheels with extra thick cast polyurethane coating, little effort is required to push the trolley. Especially when the wheels are not facing in the direction of travel. Ideally suited for mechanically driven trolleys. The wheel is suitable for both indoor and outdoor use (not for gravel floors). Typical places of use: In industrial environments. Especially for electrically driven trolleys, “lean” trolleys. Very abrasion-resistant wheel. Housing made of hardened sheet steel, galvanized colonial yellow with double, hardened ball bearings in the fork head. Aluminum core with ball bearing. Track-free and smooth-running. Particularly high wear and tear resistance.
