An exemplary lifting platform for motor vehicles has four supporting arms that are pivotally mounted on a lifting device, especially on two lateral lifting columns, and the free ends of which are movable under support points of a motor vehicle being raised. The supporting arms form a first pair and a second pair of supporting arms. At least the supporting arms of the first pair of supporting arms are adjustable in length and are implemented in the form of rigid supporting arms, which are pivotable solely about their articulation points on the lifting device. The supporting arms of the second pair of supporting arms are in the form of double-jointed arms having an additional articulated joint and, in the retracted state, are typically at least twice as long as the supporting arms of the first pair of supporting arms.

A portable wheel lifting system to assist in the replacement of a wheel on a vehicle utilizing a portable outer housing, an inner lifting linkage system to hold a wheel or tire in place, and an electrical motor to vertically raise the lifting linkage system and thus the wheel to the desired location.

A pallet shelfing apparatus for shelf racking of a pallet in a shelf structure, configured to operate in loading, unloading, and hibernate/transport modes. A transporter thereof transports and positions the platform. On a platform configured for loading and unloading the pallet from a selected shelf of the shelf structure, at least one deployable pallet carrying structure is mounted and configured for carrying, reaching and engaging the pallet. At least one deployable anchor, for temporarily stabilizing the pallet shelfing apparatus against at least one hold is deployed in the loading or unloading mode, to engage the at least one hold for stabilizing, and features the at least one hold located off ground, off ceiling, or inside the volume confined by the convex hull of the shelf structure. This volume may be disposed between the platform and at least one of the at least one hold, while in the loading or unloading mode, at least before changing mode into the hibernate/transport mode. The at least one deployable anchor is configured to change the elevation of the at least one deployable pallet carrying structure, after the carrying structure initially engages the pallet.

A lifting apparatus having at least one column. The column includes a drive that rotates a screw, the drive having a first width in a first area, and a nut housing having a support connected to a nut, the nut threaded around the screw such that rotation of the screw moves the nut and support along a first axis. The support including two parallel walls spaced apart a distance larger than the first width such that when the support is positioned at a bottom end of the screw, the two parallel walls fit over the first area. A minimum height of the support is measured from a base of the column to a lowest point of the support. The minimum height is between zero and a width between the two parallel walls.

Conventional vehicle lifts typically operate at a standard speed that is statically configured for the system, which may result in vehicles that are below the weight rating for the lift being raised at the standard speed while the lift motor is capable of safely raising at greater speeds. 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 generated 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.

A portable vehicle lift and methods of using the same is provided. The lift includes a power system, a control system, one or more batteries, and a battery management system. The control system controls the power system. The one or more batteries powers the power system. The battery management system (BMS) is configured to monitor data about the one or more batteries. The BMS may be configured to connect and/or disconnect the one or more batteries, or one or more individual battery cells, based on the data. The data may include current flowing into or out of the one or more batteries, the voltage of the one or more batteries, the level of charge of the one or more batteries, the temperature of the one or more batteries, the life expectancy of the one or more batteries, or the like.

The invention relates to a lifting apparatus for lifting and lowering vehicles, loads or the like, with a support (17) which is movable up and down and on which support (17) a load receiving means (18) is provided, wherein the load receiving means (18) has at least one supporting arm (21) which is mounted on the support (17) so as to be pivotable about a pivot axis (22), and with a locking device (37), which locking device (37) fixes the supporting arm (21) in an adjusted position with respect to the support (17), wherein the locking device (37) is released in the lowered state of the support (17) and, when the support (17) is raised, is locked and secures the adjusted pivoted position of the supporting arm (21) with respect to the support (17), wherein the locking device (37) comprises at least one actuable adjusting device (38) which is effective for the positioning of the supporting arm (21) in a pivoted position with respect to the support (17) and is automatically transferable into a locking position and fixes the adjusted pivoted position of the support (17).

A lifting apparatus (100) is disclosed. The lifting apparatus (100) includes a power driving module (1) for providing a driving force, a plurality of lifting modules (21, 22, 23) for raising and lowering a supporting module (4) upon action of the driving force, and a transmission module (3) located under the supporting module (4) for transmitting the driving force to at least one of the plurality of lifting modules (21, 22, 23). An ultrasonic inspection system is also disclosed, which includes at least one ultrasonic probe and the lifting apparatus (100) for raising and lowering a workpiece (200) at least partly immersed in a liquid to a suitable position for inspection of the 81 workpiece (200) by the at least one ultrasonic probe.

A lifting apparatus and controller therefore, where the lifting apparatus includes independently driven lifting columns and independently driven wheels that are controlled by a controller having a number of sensors such as limit sensors, position sensors, rotation sensors, laser sensors, torque sensors and the like. The independent motors for lifting and driving may also be removed easily to provide for improved servicing and maintenance.
