A portable and foldable lift can be attached to a surface such as a tailgate of a truck. The lift can be slid off the gate and used to lift heavy objects from the ground to the bed of the truck. The portable and foldable lift is returned in a folded position to the tailgate for easy storage. The portable and foldable lift can also be attached to a work bench, either on top or underneath, and can be folded up and stored out of the way.

A lifter system in accordance with the present disclosure includes a vehicle lifter that can be changed in the field by a user between a collapsed-storage mode and an expanded-use mode to lift or stabilize a portion of an object such as an overturned or inoperable vehicle.

A lifter includes a support base, a first elevating stand assembly, a first elevating-drive mechanism, a turning-drive mechanism and a bracket mechanism. A lower portion of the first elevating stand assembly is provided with two sets of first fixing racks. The support base is symmetrically mounted on the first fixing racks. One side of the first elevating stand assembly is provided with a first elevating-drive mechanism. A first elevating stand is installed inside the first elevating stand assembly. The first elevating-drive mechanism drives the first elevating stand to move through the transmission mechanism. The turning-drive mechanism is provided with a support base. One end of the support base is hinged to a movable support frame. The other end of the support base is provided with a locking assembly. The turning-drive mechanism is provided with a bracket mechanism.

Tire carriers for vehicles and related methods are disclosed. An example tire carrier includes a hinge to be pivotally coupled to a vehicle. A support arm has a first end to be pivotally coupled to the hinge and a second end to receive a tire. A jack including a beam and running gear. The beam to be pivotally coupled to the hinge and the running gear to be coupled to the second end of the support arm.

According to the present disclosure, a projector lift is provided to raise and lower a projector from the ceiling. The projector lift includes a ceiling mount normally coupled to the ceiling, a projector mount supporting the projector, a lift assembly configured to raise and lower the second mount and projector, and a stabilizer extending between the ceiling and projector mounts.

A jack comprises a planar frame having a support post and an arcuate edge member. A pivot socket is provided at a first end of the support post that is sized to receive and engage an axle portion of a vehicle. The arcuate edge member has a first end extending along the pivot socket, a second end adjacent a second end of the support post, and an outer arcuate edge extending outwardly between the first and second ends of the support post. The outer arcuate edge defines a radius of curvature greater than a length dimension of the support post. Thus, the jack is positionable between a first orientation to allow the pivot socket to receive and engage an axle of a vehicle and a second orientation to allow the support post to lift the axle.

A building system for fabricating a multi-storey building structure, the system comprising at least one first building structure and at least one second building structure and a way for elevating the second building structure to allow provision of the first building structure under the elevated building structure. A method for fabricating a multi-storey building structure, the method comprises the steps of providing a second building structure; elevating the second building structure; providing a first building structure under the elevated second building structure; and lowering the second building structure onto the first building structure. There is also provided the elevating means, such as jacks for elevating the building structure.

A device and method for moving cargo on inclined, horizontal or vertical surfaces utilizes frictional forces selectively applied through the use of induced mechanical vibrations on a loaded, platform in conjunction with the force of gravity acting on the platform. The platform is vibrated to pivot or shift the platform relative to a support structure, engaging a portion of the platform secured to the platform with the support structure. At the furthest extent of this motion, the platform is pulled against the support structure by gravity, disengaging the portion from the support structure. In turn the pivot point for the device is shifted to the point of engagement between the platform and the support structure, which enables the portion of the platform to move upwardly along the support structure. The alternation of this engagement of the platform with the support structure causes the platform to move along the support structure.
