A stirrup hoist system for hoisting a person onto a saddle includes a motor and a spool configured to be rotated by the motor. A strap is configured to be selectively rolled on, and selectively rolled off, the spool. A support configured to receive a portion of a person's body and slidingly engages the strap. The support selectively moves toward the spool, and selectively moves away from, the spool.

Disclosed herein is a controller of a hoist. The controller of the hoist includes a lift up button which is adjustable in a pressed degree; a lift down button which is adjustable in a pressed degree; a lift up switch disposed below the lift up button so as to be immediately operated when the lift up button is pressed; a lift down switch disposed below the lift down button so as to be immediately operated when the lift down button is pressed; a magnet body connected to both of the lift up button and the lift down button and disposed to descend during a pressing operation of the lift up button or the lift down button; and a Hall sensor disposed to correspond to the magnet body so as to detect a descending degree of the magnet body being pressed by the lift up button or the lift down button.

A miniature handheld electric traction device including a shell, a power supply part, a power motor, a reduction gear set, a braking part and a winding drum, wherein the power motor, the reduction gear set and the winding drum are arranged in the shell; the power motor is linked with the winding drum through the reduction gear set; a surface of the winding drum is wound with a traction rope; the reduction gear set includes a planetary gear; the sun gear of the planetary gear is coaxial with the winding drum; the power motor or the motor shaft of the power motor is inserted into the inner ring of the winding drum; the motor shaft is linked with the planetary gear.

A winch assembly including a winch housing body, an attachment structure, and one or more releasable clamps. The winch housing body may comprise a front wall, a rear wall, and at least one connecting wall that extends between the front wall and the rear wall. The front wall, rear wall, and connecting wall define a winch-receiving volume sized to house a winch device therein. The winch device may include a motor, a drum that is operatively connected to the motor, and a cable that is operatively connected to the drum. The attachment structure may be attached to the distal end of the cable. The one or more releasable clamps may be mounted to the rear wall. The one or more releasable clamps may be configured to clamp onto support rails of differing widths.
