A cam assembly (20) for a hoist mechanism includes a cam member (22), a pair of springs (24) and an input shaft (26). The cam member has a cavity (28) defined by an inner periphery of a side wall (32) and floor (34). Cutout portions (40) extend radially outwardly from the inner periphery of the cavity. The springs include a bow-shaped body portion (42) positioned between first and second connection end members. The body portion further includes an outwardly extending detent (46), each detent extending into a cutout of the cam member to operatively connect the cam member to the springs. The input shaft has a through hole (54). The first connection end members of each spring are inserted into the through hole of the input shaft, thereby operatively connecting the springs to the input shaft with a reduced number of components.
