A trailer lift that rises to high levels that may tilt for loading and unloading. The trailer lift includes a lift-and-tilt mechanism, a trailer base, and a trailer platform. The lift-and-tilt mechanism includes a lower-strut link, an upper-strut link, a support member, a lower lift cylinder, and an upper cylinder. The lower-strut link and the upper-strut link are pivotably and terminally attached to each other. The support member is positioned offset to the lower-strut link and is pivotably attached to the upper-strut link to guide the upper-strut link. The trailer platform is terminally and pivotably connected to the upper-strut link. Similarly, the trailer base is pivotably and terminally connected to the lower-strut link and the support member. The upper lift cylinder is pivotably mounted in between the upper-strut link and the trailer platform. The lower lift cylinder is pivotably mounted between the upper-strut link and the lower-strut link.

A parking lift for vehicles. The parking lift includes a platform on which a vehicle can be parked and lifted by a pair of scissor-lifts configured to raise and lower the platform to enable parking of a second vehicle beneath the platform. A deck of the platform is provided with a gradual slope throughout its length to enable vehicles with low ground clearance to travel onto the platform without contacting an underside of the vehicle with the deck. Each of the scissor-lifts includes short leg and a long leg that is longer than the short leg. Upon actuation between lowered and raised positions, the legs raise an entry end of the platform a greater vertical distance than an opposite terminal end. The platform is thus tilted upward to place a deck thereof in a substantially level or downwardly sloping orientation from the entry end toward the terminal end.

A mechanism for a scissor lift (1) or for a tilt system (21) is disclosed, which mechanism comprises a lower frame (2), an upper frame (3), a controlling arm (6), a lifting arm (7) and a power source (8) and is configured in such a way that an extension of the length of the power source (8) causes the lifting arm (7) to pull a fulcrum (14) on the first lever arm (4) or a fulcrum (22) on the second lever arm (5) in a direction away from the lower frame (2), which, in turn, causes the lowermost end of the second lever arm (5) to be pulled towards the lowermost end of the first lever arm (4) and at least one end of the upper frame (3) to be forced away from the lower frame (2). The power source (8) will provide a substantially constant power throughout the motion when the mechanism being used in a scissor lift, whereas, the power source (8) may give maximum power in the beginning of the motion and less power later on in a tilt system. Furthermore, a scissor lift (1) and a tilt system (21) each comprising such a mechanism and a wheel chair comprising such a scissor lift and/or such a tilt system are disclosed.

A lift assembly for a storage area includes a floor supported by a scissor mechanism, an actuator for raising the floor from a neutral position to an elevated position, a plurality of members attached to the floor, guide members within which the plurality of members move, and a detent movable between an extended position wherein a portion of the detent protrudes into the guide member and contacts one of the at least two members sufficient to resist movement of the at least two members and a retracted position wherein the at least two members freely move within the guide members. The floor is movable between a non-extended position and a fully extended position when the scissor mechanism and the floor are in the neutral position, the elevated position, or any position between the neutral and elevated positions, and may be removed from the assembly.

The present invention belongs to the field of frames and mechanisms for lifting vehicles and other heavier objects or persons. The invention relates to a transportable foldable lifting platform preferably useful for lifting vehicles with the purpose of their exposition. The essence of the invention is in that it comprises: a base triangular construction (2) and suitable plate and/or sleds (21) for a vehicle, arranged on the base triangular construction to which the vehicle may be driven; three three-part lifting legs (3), wherein each of the lifting legs is equipped with at least one hydraulic cylinder (34) and with a parallelogram mechanism, so that the parallelogram can be folded or extended depending on the position of both parts of the lifting legs, which is defined with each of the hydraulic cylinders controlled with suitable hydraulic valves; a drive part; and electronics for controlling hydraulic valves of the hydraulic cylinders, movement of each of the lifting legs and ensures self-adjustability of the platform.

A cart assemblies and methods of use for supporting and positioning a work piece during manufacturing. The cart assembly includes a table with a work surface configured to support the work piece. The table is connected to a base that is configured to move the table along a work floor. A lift mechanism adjusts the elevation of the table above the work floor, and a tilt mechanism adjusts an angle of the table relative to the work floor. The lift and tilt mechanisms may be used separately or simultaneously to adjust the position of the table as needed. The cart assembly also includes a trolley. The trolley is configured to receive and support the work piece away from the base. This provides for access to additional sections of the work piece during assembly.

The invention relates to a movable base for transporting equipment by land, in particular aeronautical equipment. The movable base comprises a frame including two side arms designed to move parallel to one another and means for rolling on the ground, which are connected to the frame. Each side arm comprises lifting means designed to move the equipment vertically and to tilt same between the side arms.

A lift and tilt support apparatus includes opposed scissor lift assemblies. Each scissor lift assembly includes a base, an upper frame, and scissored first and second legs, each having opposed top and bottom ends. The bottom end of the first leg is pivoted to the base, and the top end of the first leg is mounted to the upper frame for reciprocal movement. The top end of the second leg is pivoted to the upper frame, and the bottom end of the second leg is mounted to the base for reciprocal movement. The top end of the first leg reciprocates in a direction skewed from the top end of the second leg. The bottom end of the second leg reciprocates in a direction skewed from the bottom end of the first leg.
