US 6,027,295 A · Lifting system for manufactured and mobile homes

Abstract

A lifting system for moving mobile homes that includes wheeled jack assemblies, jack units assembled from such assemblies and a segmented track for supporting such assemblies and units. Each jack assembly preferably includes a jack rollingly carried on wheels, and a roller head operatively connected to the working end of the jack to move from a lowered position to a raised position. The wheels allow lateral adjustment of the home, while the roller head allows longitudinal adjustment of the home. In the preferred embodiment, each jack unit includes two jack assemblies, with one of the assemblies further including a drive motor operatively connected to its wheels. Furthermore, the assemblies are interconnected by a hydraulic power unit in the form of a housing that encloses and protects the hydraulics for controlling each jack and drive motor. Each segment in the segmented track generally includes a pair of rails structurally interconnected, with a hole formed adjacent each end of the segment. Segments are then connected to each other by a coupling plate that underlies the ends of the segments.

Dependent claims

A system for use in lifting mobile homes, comprising:

a jack;
at least two wheels operatively connected to the jack for rollingly carrying the jack;
a hydraulic power unit for providing pressurized hydraulic fluid to the jack, the hydraulic power unit including valves for controlling the operation of the jack;
a remote controller for controlling the operation of the valves, the controller including a switch assembly remote from the hydraulic power unit;
a pair of parallel axles extending outwardly from the jack, each axle terminating in a distal end;
and
a rod interconnecting the distal ends of the axle to create a handle for carrying the jack;
wherein at least one of the wheels is mounted on one of the axles, and another of the wheels is mounted on another of the axles.

5 more elements

A lifting system for lifting mobile homes, comprising:

a jack having a working end and a base, the working end moving relative to the base;
wheels operatively connected to the jack for rollingly carrying the jack;
and
a roller head operatively connected to the working end of the jack, the roller head including a horizontal roller exposed for rollably supporting a mobile home, and an aligner for keeping the roller head aligned with the mobile home;
wherein the aligner includes a vertical roller exposed for rollably engaging a vertical surface of the mobile home, thereby keeping the roller head aligned with the vertical surface of the mobile home.
