A compact, motorized hoist including a U-shaped member, the open end of which is rigidly fastened to a first leg of an L-shaped member. The support panel leg of the L-shaped member extends across the open side of the U-shaped member. An electric motor is rigidly fastened to the support panel leg of the L-shaped member and is drivingly linked to a worm gear shaft extending through a gap between the support panel leg of the L-shaped member and the open side of the U-shaped member. The worm gear shaft is journalled to the L-shaped member. The worm gear drives a first gear having an axle mounted perpendicular to the first leg of the L-shaped member, and the closed end of the U-shaped member. A cable is wound around a reel rigidly mounted to the axle. The L-shaped member is removably fastened to the U-shaped member, and one leg of the U-shaped member is removably fastened to a pier member.
