Four-Wheel Monorail Trolley No. A-189 consists of two trolleys No. A-188 coupled by a malleable load bar. It is a sturdy, free-running ball bearing trolley. It can be used in the ordinary way as a single unit, or for carrying racks or special carriers.

Where the application is for light loads and requires a great many trolleys, the great carrying strength of the Monorail rail section will permit a wider spacing of hangers and the covering of longer spans. In most cases this will eliminate special supporting superstructure, bringing the cost of both equipment and installation down to a point where, for even very light service, the investment is justified.

Additional Information

Additional Information

N/A The drop forged steel wheels are mounted on self-contained ball bearings. The wheels are carried in a malleable iron yoke. While the two-wheel trolley can be used in single units, it is especially recommended for use in pairs, attached to carrying bars, special racks, or for powder-operated chain-driven installations where any number of trolleys can be connected.

Not recommended for use with hoists.
