A three-level vehicle lift. The lift includes a four-post configuration in which each post includes a pair of vertically extending, side-by-side channels. Two platforms are provided. Each includes a carriage configured to engage a respective one of the channels in each post and a hydraulic actuator and lifting cable system disposed within the platform for lifting the platform. An actuation system having a single hydraulic pump is provided with a valve for selectively supplying hydraulic power to either an upper- or a lower-platform hydraulic circuit. The simplified lift and actuation system configuration reduces manufacturing, shipping, installation, and materials costs and complexities.

Provided is a lifting device, lifting system and method for lifting a vehicle. The lifting device according to the invention includes a frame with a carrier configured for carrying the vehicle; a drive which acts on the carrier, wherein the drive includes an integrated hydraulic cylinder drive unit configured for raising the carrier with the integrated hydraulic cylinder drive unit including: a housing of a cylinder; a piston rod movable in the housing; a height measuring system configured for measuring the displacement of the piston rod; and an integrated hydraulic fluid tank and motor unit that is configured for driving the piston rod.

In order to improve the safety of a lifting platform with respect to risk of a vehicle falling, provision is made, in a lifting platform having carrying arms, which can be vertically adjusted by a lifting mechanism, for raising the vehicle and having carrying plates, which are arranged at a free end of the carrying arms, for carrying the vehicle to be lifted, for a sensor arrangement having a plurality of pressure sensors which are arranged distributed over a bearing surface of the carrying plates to be installed on each of the carrying plates and for a display which displays a pressure distribution over the bearing surface of the respective carrying plate to be associated with each carrying plate.

A hydraulic lifting column comprising a base structure, a head structure and a lifting structure. The lifting structure comprising a hydraulic power unit and hydraulic linear actuators extending between the base structure and the head structure, the hydraulic power unit acting on the hydraulic linear actuators. The lifting structure comprising four linear actuator units with a mutually parallel, vertically oriented working direction. Each linear actuator unit comprising a double cylinder having two-cylinder bores arranged next to one another and two piston structures with piston rods oriented parallel to one another and extendable in opposite directions from the double cylinder. The four lower piston rods are connected to the base structure at the corners of a first quadrilateral and the four upper piston rods are connected to the head structure at the corners of a second quadrilateral.

Systems and methods for mast stabilization on a material handling vehicle are provided. In one aspect, the present disclosure provides systems and methods for a hydraulic circuit configured to stabilize a mast of a material handling vehicle in dynamic and static events. The hydraulic circuit is integrated into a typical hydraulic system used to raise and lower the mast and thereby a load supported by the mast.

Techniques are disclosed for methods and systems for automating the operation of vehicle lifts in the servicing of automotive vehicles. The lifts may be motorized mobile column lifts and/or fixed lifts, including two-post lifts with swing-arms and a variety of drive-on lifts. Motorized mobile lifts have a motorized transport mechanism. A guidance system first assigns available motorized mobile lifts to the axled wheels of a vehicle and then directs their transport mechanism for transporting them to their engagement locations. It also guides the engagement of both the motorized mobile lifts and the fixed lifts in the service center. A number of technologies may be used for this purpose, including sensors onboard the vehicles and/or the lifts and/or the service center. A computer vision pipeline may also be utilized to assist in the process. Machine learning may also be employed. Techniques are also extended to autonomous vehicles as well as interfacing with fleet management software.

The present invention relates to a hydraulic height adjusting device for installing a heavy-weight structure to secure stable horizontal bearing power against a horizontal load of a heavy-weight upper structure. The present invention includes a lower frame which is installed on a top surface of the carrier and is provided with a plurality of receiving portions formed in an upwardly opened shape; and a hydraulic cylinder which is disposed in and engaged to the respective receiving portions of the lower frame, the hydraulic cylinder being moved in a vertical direction to adjust the height of the upper structure, in a state in which an upper end thereof supports the upper structure. The receiving portion is provided with a support guide which is interposed between an inner wall of the receiving portion and the hydraulic cylinder to annually enclose the hydraulic cylinder and thus prevent the hydraulic cylinder from being tilted.
