International Classification:

B66F 710

US Classification:

187215, 187205, 187272

Appl. No.:

10/833266

Inventors:

Jason Stewart - Madison IN, US

Assignee:

Delaware Capital Formation, Inc. - Wilmington DE

International Classification:

E05D 11/10

US Classification:

16354, 16356

Abstract:

A hinge pin is suited for use in a hinge for a rotatable arm of a vehicle lift. The hinge pin has a groove formed within its side surface. The groove is configured to permit engagement of the pin with a restraining member configured to prevent rotation of the arm. The engagement of the pin with the restraining member limits longitudinal movement of the pin.

International Classification:

B66B 1/34

US Classification:

187391, 187210, 187247

Abstract:

A lift control interface is operable to control and monitor a lift system. Each lift column in the system has such a lift control interface. The lift control interface allows a user to assign lift columns to a lift system. One or more of the assigned lift columns may be assigned to a column control group. The user may lock the selection of these columns. The status of the assigned, selected, and locked lift columns may appear on every lift control interface in the lift system. The user may govern operation of the selected columns in the column control group from a single control interface, such as any control interface at any of the selected columns. The lift control interfaces may include visual representations showing the relationships between the lift columns and a vehicle, such as with lift column icons being positioned around a vehicle icon.

Appl. No.:

10/173510

Inventors:

Jason Stewart - Madison IN, US

International Classification:

B66F007/12
B66F007/28

US Classification:

187/213000, 187/219000

Abstract:

A vehicle lift, a vehicle lift overhead assembly and a method for assembling a vehicle lift utilizes mounting configurations on each of the end of a cross member of the overhead assembly and a bracket for attachment to the upright column of the lift, with at least one of the mounting configurations including a plurality of mounting patterns which allow the member to be attached to the column by the bracket at any of a plurality of orientations relative to the column. The plurality of mounting patterns may include holes, pins or any feature capable of cooperation with complementarily shaped features to orient and secure together the components of the overhead assembly, such as slots, clamps and other similarly functioning structures.

International Classification:

B66F 17/00
B66F 7/16

Abstract:

A set of lift controls may be configured to determine the load on the motor () by a vehicle of an unknown weight during operation at a standard lift speed and use such information to determine a potential speed that the motor may raise the vehicle at while staying within safe operational levels for the motor. One or more of a magnitude of electrical power drawn, a pressure generating by a hydraulic lifting, or a sensed vehicle weight may be used to provide an indication of load on the motor and/or a higher potential speed.

International Classification:

B60K 17/04
F16H 1/20
F16H 57/023

Abstract:

A portal gear box assembly effective to lift and change the gear ratio of a wheel of an off-road vehicle includes a housing, an input gear sub-assembly, an output gear sub-assembly, and an idler gear sub-assembly effective for linking the input gear to the output gear. The input gear sub-assembly includes an input gear, the output gear sub-assembly includes an output gear, and the idler gear sub-assembly includes at least one idler gear and at least one removable adaptor effective for holding the idler gear in either a first position or a second position different from the first position. The sub-assemblies may also include bearings to facilitate movement of the gears.

Inventors:

- Madison IN, US
Jason Stewart - Harvest AL, US

International Classification:

F16H 57/04
F16H 57/02

Abstract:

A portal gear box assembly for an all-terrain vehicle includes: a portal gear box housing a set of gears and linking an axle to an output shaft; a lubricating oil contained in the gear box; and a fluid circulation loop that circulates a cooling fluid to a cooling location outside the gear box. The cooling fluid may be a lubricating oil. The fluid circulation loop may include a pump and/or a filter. The cooling location may pass the fluid through a structure such as a radiator or other cooler. The circulation loop and/or any radiator/cooler, filter, or pump contained therein, may serve a single portal gear box, or may serve two or more portal gear box assemblies.
