Abstract
A hoist assembly includes a housing having a body sandwiched between metal plates connected to a mounting channel. The housing supports a rotary drive shaft which supports a rotary spool defining a groove receiving a cable having an inner end portion connected to the spool. A drive mechanism connects the shaft to the spool and produces one revolution of the spool for multiple revolutions of the drive shaft. A down stop member moves radially within the groove while engaging the cable, and an alternate one-piece down stop member surrounds the cable and engages the spool on opposite sides of the groove. An elongated wheel support bracket is connected to the outer end of the cable and has opposite inclined straight surfaces for self-centering wheels with center holes of different diameters. Another wheel support bracket has opposite end portions having pins projecting upwardly into lug holes within the wheel.
