An automobile jack includes a housing having opposed side and end walls defining an interior area. A ramp extends from the housing and includes upper and lower ends. A platform defines a tire-receiving surface. The automobile jack includes a first linkage having an upper arm pivotally connected to a lower arm along a first horizontal axis and a second linkage having an upper arm pivotally connected to a lower arm along a second horizontal axis. Each upper arm is pivotally connected to the platform and each lower arm is pivotally connected to the housing. A threaded yoke is coupled to the second linkage. The jack includes a power screw for selectively changing a distance between the first and second horizontal axes to move the platform between a retracted configuration at which the tire-receiving surface even with the ramp and a raised configuration above the ramp.

A system and method for leveling a selected surface of a structure. The system includes a handheld mobile device and a platform leveling assembly (PLA) supportable on a structure to be leveled. The PLA includes a PLA controller and a PLA receiver communicatively coupled with the PLA controller. The handheld mobile device includes a tilt sensor configured to sense an attitude of a selected surface on which the handheld mobile device is placed; and a mobile device controller communicatively coupled to the tilt sensor and the transmitter and configured to receive signals from the tilt sensor indicating the attitude of the selected surface on which the handheld mobile device is placed.

A vehicle lift comprising a vertically-orientated column and a pair of swing arms vertically-shiftable with respect to the post. The swing arms are configured to rotate with respect to the column. The vehicle lift additionally includes a sensor associated with each swing arm. Each sensor is configured to obtain information related to its respective swing arm. Each sensor is also associated with a radio-frequency identification (RFID) tag, with the RFID tag being configured to provide power to its respective sensor. The vehicle lift further includes a system controller in communication with the sensors and configured to control the vehicle lift based on the information obtained by the sensors.

A wheel support is provided for use with a motorcycle stand. The wheel support includes a pair of side plates, each of which has a first side end and a second side end distal thereto. At least one of the side plates has a curved end about the first side end to secure onto a portion of the motorcycle stand. The wheel support includes a top plate secured between the pair of side plates and an adjustable height mechanism configured to adjust the height of the second end of the side plates and thus adjust the height of the top plate about the second end. The top plate when moved under the wheel of the motorcycle is movable to engage and lift the wheel of the motorcycle into and out of engagement with the motorcycle.

A leveling system includes a plurality of leveling blocks for leveling a relatively large vehicle and a handle for securing the plurality of leveling blocks together for convenient storage and transport of the leveling blocks without a container. Each leveling block includes a pattern of protrusions that extend upwardly from a top surface and a pattern of recesses formed in a bottom surface. Each leveling block has an opening formed therethrough and at least one of the openings is provided with an internal thread. The handle includes an extensible and retractable portion adjacent a proximate end thereof and an external thread at a longitudinal opposite distal end thereof. The handle is guided through the openings of the plurality of leveling blocks and the external thread engages the internal thread provided on the at least one opening to secure the leveling blocks together.

Robotic enabled lift concepts are described. In one embodiment, a vertical lift includes a vertically directed track assembly and linear actuator that extend between first and second levels. The lift further includes a lift platform having a continuous contact roller such as a continuous belt, for example, a platform guide assembly for engagement with the track assembly, and a motion translation mechanism mechanically coupled between the continuous contact roller and the linear actuator. A robotic drive unit can drive upon and dock with the lift platform. In that docked position, the robotic drive unit can rotate its drive wheels to raise or lower itself between the first and second levels based on the translation of the motive forces of the drive wheels through the motion translation mechanism and to the vertically directed linear actuator. Other embodiments include a lift arm, an inclined track assembly, and a lift carriage.

A lift for raising and lowering items, such as vehicles. The lift comprises a lifting assembly including a cylinder and a ram configured to extend from and retract within the cylinder. The lift additionally includes an air-storage reservoir configured to store pressurized air received from an external air source. The air-storage reservoir is fluidly connected to the lifting assembly, such that the air-storage reservoir is configured to cause the ram to retract within the cylinder even when the lift is not connected to the external air source.
