Abstract

This is a portable winching device to facilitate the delivery of spas and hot tubs (or other bulky heavy items) quickly and safely onto high decks or platforms. The hoisting device consists of a frame with a pivot shaft made preferably of steel or other strong stiff material. Attached to the arm in this case is a conventional winch containing in this case steel aircraft cable of suitable strength to handle the load. Any suitable winch, come-a-long, electric hoist etc. could also be used that is capable of sustaining the weight. The frame also has attached two wheels for mobility. The base frame is temporarily attached to a deck or a structure via four (4) ratchet straps encircling the joist or main supports of the deck base. This provides a very stable lock down of the frame. The pivot shaft is attached to a chain that is attached to the rear of the base frame at two points. When a load is placed on the unit, the chain will support the pivot shaft. The chain will also let the pivot shaft rise to the correct height for ease of use in engaging the winch. When there is no load the chain will collapse lowering the pivot shaft until it is parallel with the base for disassembly. The spa/hot tub is then placed on the wooden beams of a temporary ramp. A strap capable of handling the weight is placed around the spa/hot tub and tightened. The cable of the portable winch system is attached to the strap on the spa/hot tub via a steel hook. The spa/hot tub can now be pulled onto the deck up the ramp by means of engaging the winch on the pivot shaft of the base unit. Once the spa/hot tub is in place on top of the deck, the system can then be quickly disassembled and taken to the next job. Two (2) individuals that are skilled in the delivery and placement of spas/hot tubs can accomplish this portable winching system with ease.
