Units with capacities from 1/4 through 12 tons employ universal wheel treads for use on flat or tapered beam flanges. Units with capacities from 16 through 25 tons operate on American Standard I-beams with tapered flanges.
Heavy rolled steel side frames extend beyond the wheels to provide these trolleys with superior strength, rigidity and added protection for the trackwheels.
Trolley wheels are fully machined from alloy cast iron and hardened for high strength and long life. Alloy steel axles and equalizer pins are heat treated for maximum strength and wear life.
Geared versions have fully machined trackwheel gears and incorporate a swinging chain guide which keeps the hand chain aligned and free from jamming.
