## Abstract

A selectively positionable lifting system for a utility trailer, or the like, in which a jacking system is selectively attachable to a strategic position of the utility trailer in order to lift said trailer at the jack point for maintenance and repair purposes, the jacking system being easily removed and stowed when not in use.

## Claims

### Claim 1

A selectively positionable lift system for utility trailers, the trailer having a frame, a tongue extending outwardly from the frame and supporting wheels, comprising
a jacking system, said system including a jack, a mounting plate secured to said jack, a supporting plate releasably connected to said mounting plate, said support plate having a cantilevered receptacle protruding therefrom;
a connector bracket engageable with the utility trailer; said connector bracket having a cantilevered connector protruding therefrom, said cantilevered connector adapted to be received in said cantilevered receptacle to thereby selectively engage said jacking system with said utility trailer at a point along said side rail to permit at least a portion of said trailer to be lifted for the purpose of maintenance or repair.

### Claim 2 (depends on 1)

The lift system for utility trailers of claim 1, wherein said cantilevered receptacle and said cantilevered connector are formed of rectangular tubing.

### Claim 3 (depends on 1)

The lift system for utility trailers of claim 1, wherein said cantilevered receptacle and said cantilevered connector extend outwardly from the lower portion of said mounting plate and said connector bracket respectively.

### Claim 4 (depends on 1)

The lift system for utility trailers of claim 1, wherein said supporting plate and said mounting plate are interconnected, said interconnection being a quick disconnect arrangement, whereby said jack is selectively rotatable between a vertical position and a horizontal position.

### Claim 5 (depends on 1)

The lift system for utility trailers of claim 1, wherein said utility trailer includes at least two wheels; said connector bracket being engaged with said utility trailer adjacent at least one of said wheels at a time.

### Claim 6 (depends on 1)

The lift system for utility trailers of claim 1, wherein said utility trailer includes at least two wheels; a said connector bracket being disposed adjacent each wheel of said utility trailer.

### Claim 7 (depends on 1)

The lift system for utility trailers of claim 1, wherein said utility trailer including a tongue, said tongue being attachable to a tow vehicle; said connector bracket being attachable to said tongue.

### Claim 8 (depends on 3)

The lift system for utility trailers of claim 3, wherein apertures being formed respectively in said cantilevered receptacle and said cantilevered connector, said apertures being aligned when said cantilevered connector is inserted in said cantilevered receptacle; a fastener inserted in said aligned apertures to hold said cantilevered receptacle and said cantilevered connector together.

### Claim 9 (depends on 3)

The lift system for utility trailers of claim 3, wherein said utility trailer includes at least two wheels; a said connector bracket being disposed adjacent each wheel of said utility trailer.

### Claim 10 (depends on 1)

The lift system for utility trailers of claim 1, wherein said cantilevered receptacle and said cantilevered connector extend outwardly from the upper portion of said mounting plate and said connector bracket respectively.
