The 5:1 design factor allows the PT Series to be used with both manual or powered hoists. Meets pertinent U.S. (ASME/ANSI and CMAA), Canadian and European standards.
The side plates, including the rail sweeps/drop stops, are made of cold formed steel for strength, durability and even load distribution.
The wheel axles are 'rivet-locked' in place so they will not come loose. They are NOT knurled, welded, or modified bolts.
The wheels are cast iron. The 'universal' tread fits either flat or tapered beams.
Wheels run on sealed, 'lubed-for-life' ball bearings. Smoother rolling with less effort and...less maintenance.
Wide hanger shaft assemblies allow the PT Series trolley to fit almost any I-Beam, H-Beam or patented track beam up to 8.06 in./205 mm width.
PT Series trolley hanger shafts are designed to accept all hoist brands. The hanger shaft has a 'squared out' recess to accept round or squared hook shapes.
The trolleys are painted black for universal coordination.
Shaft extension kits allow standard trolleys to fit almost any S-beam or patented track beam - flange adjustment 8'-13'. Please click on 'catalog section' for details.
