Chester Swivel-Truck Precision-Bearing Manual Geared Trolley - 1 Ton, 3 to 4-5/8 in Beam Flange

Product Description

Chester swivel-truck precision-bearing manual geared trolleys provide controlled horizontal travel for compatible hoists and suspended loads operating on overhead runway beams. The listed configurations cover capacities from 1/4 to 6 Ton and are sized for specific beam flange widths, beam heights, curve radii, and trolley-wheel dimensions. Manual geared operation is suitable for applications where the operator requires more accurate load positioning and lower travel effort than a conventional plain push trolley can provide.

The hand-operated geared travel mechanism transfers movement to the trolley wheels, allowing the suspended hoist and load to be moved gradually in either direction without an electric or pneumatic traverse motor. The swivel-truck design allows the wheel assemblies to align with the runway as the trolley travels, supporting operation on compatible curved beams. Precision-bearing wheel assemblies promote smoother rolling and help reduce the effort required to move properly supported loads.

The 1/4 and 1/2 Ton models fit beam flanges from 2-5/8 to 4-5/8 in, accommodate a 4 in beam height, have a 9-7/8 in minimum-radius curve, and use a 4 in wheel-tread diameter. The 1 Ton model fits 3 to 4-5/8 in flanges with a 5 in beam height, 9-7/8 in minimum-radius curve, and 5 in wheel-tread diameter. The 1-1/2 and 2 Ton models fit 3-5/8 to 5-1/2 in flanges with a 6 in beam height, 19-1/2 in minimum-radius curve, and 6 in wheel-tread diameter. The 3 and 4 Ton models fit 4 to 7 in flanges with an 8 in beam height, 15-3/8 in minimum-radius curve, and 8 in wheel-tread diameter. The 5 and 6 Ton models fit 4-5/8 to 8 in flanges with a 10 in beam height, 33-7/8 in minimum-radius curve, and 9 in wheel-tread diameter.
