Abstract:
1. A hoist spooling assembly for spooling a cable about a drum, comprising: a frame having a base portion and first and second spaced support portions, the base portion having a top surface, the first and second support portions extending upwardly from the top surface of the base portion and defining respective openings; a rod having a longitudinal axis and opposed first and second ends, the first end of the rod being configured for secure coupling to the base portion of the frame; first and second bushings configured for receipt within the respective openings of the first and second support portions of the frame, the first and second bushings defining respective openings; first and second arms having respective proximal and distal portions, the proximal portion of the first and second arms defining respective openings; an elongate suspension unit defining a central bore having a prescribed geometric cross-sectional shape; a retainer defining at least one opening configured to receive at least a portion of the elongate suspension unit, the retainer configured for adjustable coupling to the second end of the rod; an elongate shaft having a longitudinal axis and opposed first and second end portions, the elongate shaft having an external surface configured for receipt within the central bore of the elongate suspension unit such that the first and second end portions of the elongate shaft extend from the central bore of the elongate suspension unit and the longitudinal axis of the elongate shaft is substantially perpendicular to the longitudinal axis of the rod and is substantially co-axial with a longitudinal axis of the central bore of the elongate suspension unit, wherein at least the portion of the external surface of the elongate shaft received within the central bore has a complementary geometric cross-sectional shape to the prescribed geometric cross-sectional shape of the central bore; first and second spacer tubes, the first spacer tube configured to receive the first end portion of the elongate shaft, the second spacer tube configured to receive the second end portion of the elongate shaft; and a roller securely coupled to and positioned between the distal portions of the first and second arms, the roller being configured for engagement with the cable, wherein, in an operative position of the hoist spooling assembly, the first end portion of the elongate shaft extends through the first spacer tube and the opening of the first bushing such that at least a portion of the first end portion is positioned within the opening of the proximal portion of the first arm and the second end portion of the elongate shaft extends through the second spacer tube and the opening of the second bushing such that at least a portion of the second end portion is positioned within the opening of the proximal portion of the second arm, wherein, in the operative position, the proximal portion of the first arm is configured for secure coupling to the first end portion of the elongate shaft, and the proximal portion of the second arm is configured for secure coupling to the second end portion of the elongate shaft, and wherein the elongate suspension unit the elongate suspension unit selectively transmits angular torque to the elongate shaft, which in turn, transmits the angular torque to the coupled first and second arms and hence to the cable.
