A mobile lift caddy is configured to remove a vehicle from a primary lift while the vehicle is elevated above the workplace floor and then transport the vehicle to another location. The mobile lift caddy is dimensioned to fit between vertical lift posts of the primary lift. A mobility drive arrangement moves the caddy under operator control to and from the workplace location. Caddy lift arms are configured to accept a portion of removable lift pad assemblies at the lift arms of the primary lift, to lift out the lift pad assembly with the vehicle supported on the lift pads.

The present disclosure concerns a lifting apparatus for lifting heavy machinery, comprising first and second spaced-apart lifting devices vertically extendable, each lifting device comprising a beam-receiving portion; and a transverse lifting beam comprising a beam body engageable with a portion of the heavy machinery, and first and second opposed mounting end portions removably engageable with the beam-receiving portions, for the transverse lifting beam to extend between the lifting devices. Each beam-receiving portion comprises one of a male connector and a female connector and each mounting end portion comprises the other one of a male connector and a female connector detachably engageable to the one of a male connector and a female connector of the corresponding beam-receiving portion. The present disclosure also concerns a kit for forming such a lifting apparatus, a lifting assembly comprising at least first and second lifting apparatuses and a method for lifting heavy machinery.

Disclosed is a wheel based measuring system and a method for lifting a vehicle. The lifting system includes one stationary lift; a number of moveable lifts; positioning means for defining a position of a wheel axle of the vehicle; distance measuring means for determining the distance of the vehicle to a reference point; and control means for determining the distance between two vehicle axles and steering the one or more moveable lifts to the correct position.

A push-up system for heavy loads comprising multiple lift modules that are usable to collectively support and raise a load, wherein each lift module is capable to receive a support beam on top of it, and wherein the support beam is placeable on top of the lift module in at least one of a first direction and a second direction which traverses the first direction, and wherein each lift module is equipped with supports for the support beam, wherein the supports are swivably mounted at an upper end of the lift module and arranged to be displaceable between a first position wherein the support's guiding surface is horizontal and a second position wherein the supports are swiveled away from the first position so as to arrange that the support's guiding surface is perpendicular with said upper face of the lift module.

The present disclosure, in one or more embodiments, relates to a drilling rig with a self-elevating drill floor. The drilling rig may have one or more jacking systems that may operate to raise the drill floor. The one or more jacking systems may raise the drill floor to a height sufficient to accommodate a substructure such as a substructure box. A substructure box may be placed, and the one or more jacking systems may lower the drill floor onto the substructure box. Substructure boxes may be placed beneath the drill floor, using the one or more jacking systems, until a desired drill floor height is reached. In some embodiments, the one or more jacking systems may additionally operate to move the drilling rig, for example between adjacent wells on a pad drilling site. The jacking systems may operate the move the drilling rig using walking feet or another movement mechanism.

An apparatus/method for a conveyor belt lifter apparatus that can be manually-configured to accommodate differently-sized conveyor belts of conveyor systems. The apparatus includes a pair of lifts in between which a trough-shaped adjustable conveyor belt support arm is releasably-secured. An adjustable shaft coupler connects the lifts to allow simultaneous activation and movement of both lifts by an operator engaging only one lift. An adjustable base also allows the apparatus to be adjusted for the conveyor system size. These adjustable components comprise segments that can be releasably secured using quick-release pins. The height of the ends of the conveyor belt support arm can also be manually adjusted to eliminate any gap between the conveyor belt and the support arm before lift activation. Each lift comprises a manually-controlled screw jack with an extender formed thereon to allow the lifter apparatus to raise or lower the particular conveyor belt once the lifter apparatus is installed.
