Commercial / Industrial Hardware > I-Beam Trolley
Our I-Beam Trolleys are designed to be used for very heavy
doors where the service conditions are severe, radiation
doors, blast doors and sound proof doors. Precisely machined
wheels are equipped with Timken tapered roller bearings
supplying a combination radial and thrust load capability
for a lifetime of maintenance-free service. Axles are
equipped with grease fittings to allow for pressure
lubrication. Wheel flanges on trolleys are hardened starting
from 3-ton capacity and larger.
