US 2001/0040233 A1 · Portable motorcycle hoist

Abstract

A portable motorcycle hoist has a main frame assembly which includes a pair of vertically-oriented parallel channel beams rigidly affixed to both an upper cross brace and to a base member. The pair of channel beams provide a caged track for a trolley which is movably slideable therein between a lowermost position and an uppermost position. The trolley is fitted with a plurality of guide wheels to minimize sliding friction within the caged track. A cradle assembly, adapted to support a motocycle beneath its engine, is attached to the trolley. Attachment may be made with welds, threaded fasteners, or the cradle may simply be clipped to the trolley. The base member may be unitary, or it may be partially disassemblable to facilitate transport and storage. The base member may also incorporate casters to facilitate the repositioning of a supported cycle. A first preferred embodiment of the invention includes a first pulley mounted on the upper cross brace, a second pulley mounted on the trolley, and a battery powered electric-motor-driven winch mounted on the base member. A second Preferred embodiment of the invention utilizes a rail jack to raise and lower the trolley.

Dependent claims

A motorcycle hoist comprising:

a main frame assembly having a pair of vertically-oriented parallel channel beams rigidly affixed to both an upper cross brace and to a base member, the channel of each beam facing and directly opposed to the channel of the other, said pair of channel beams forming a caged track;
a trolley movably slidable within said caged track between a lowermost position and an uppermost position, said trolley incorporating a plurality of attached guide wheels, all of which ride against the inner surfaces of at one channel, and which minimize sliding friction within the caged track;
a cradle assembly attachable to said trolley, said cradle assembly adapted to support a motorcycle beneath its engine;
and
a rail jack coupled between said base member and said trolley for raising and lowering said trolley within said caged track.

A motorcycle hoist comprising:

a main frame assembly having a pair of vertically-oriented, spaced-apart, parallel channel beams rigidly affixed to both an upper cross brace and to a base member, said pair of channel beams forming a caged track;
a trolley movably slidable within said caged track between a lowermost position and an uppermost position, said trolley including a rigid structure to which at least four stub axles are mounted such that the axes thereof are coplanar and both perpendicular to the direction of trolley travel and parallel to said upper cross brace, each stub axle having mounted thereon a primary guide wheel, at least two primary guide wheels riding against parallel interior surfaces of each channel beam, said trolley further including at least four secondary guide wheels, each of which is rotatable about an axis perpendicular to the plane in which the axes of said stub axles lie, at least two of said secondary guide wheels riding against an interior surface of each channel beam that is perpendicular to the parallel interior surfaces;
a cradle assembly attachable to said trolley, said cradle assembly adapted to support a motorcycle beneath its engine;
and
a rail jack coupled between said base member and said trolley for raising and lowering said trolley within the caged track.
