Chester, Model PS Trolleys combined with our hook type hoists, provide an economical means of transporting loads.

  Frames: Design embossed steel sideplates on the 1/4 through 2-ton models provide a high strength to weight ratio. Sideplates are of warp-around design providing a full face bumper as well as a protective lug which will prevent the trolley from falling off I-beam in event of inadvertent wheel axle failure. The 3-ton trolley sideplate frames are thick rolled steel sections with added bumpers.

  Wheels: High-quality pressed steel wheels, carbonized and hardened to ensure long life, are offered on the standard trolleys. The wheels have built-in ball bearings to provide smooth easy rolling action and compound tread design to make them suitable for operation on wide flange beams as well as American Standard I-beam tapered flange beams. Deep flanges help prevent wheels from climbing up onto the track. Pressure lubrication fittings in the axles allow easy lubrication.

Cross Pin: The cross pin connects the sideplates and provides equalized wheel loads. It has a center located hook saddle groove designed for mounting hook suspended hoists permitting the closest possible headroom. For hoists which will not hook over the cross pin a pear-shaped ring is supplied. Each trolley is easily adjustable to fit several sizes of beams by simply shifting cross pin spacer washers from inside to outside of trolley sideplate.
