A side saddle slingshot drilling rig includes a left and right substructure including a left and right lower box. The side saddle slingshot drilling rig includes a drill rig floor mechanically and pivotably coupled to the left and right lower boxes such that it is pivotably movable from a lowered position to a raised position. The drill rig floor includes a V-door. The V-door is positioned on the V-door side of the drill rig floor. The V-door side of the drill rig floor is oriented to face the right substructure. A mast coupled to the drill rig floor may include an open side, defining a mast V-door side. The mast V-door side may be oriented to face the right substructure. The mast may pivot into its raised position or may be a bootstrap mast.

Implementations described herein provide a lift pin actuator. The lift pin actuator has a housing. The housing has an interior volume. A track is disposed in the interior volume and coupled to the housing. A center shaft is at least partially disposed in the interior volume of the housing. A guide is movably coupled to the track. At least one internal bellows is disposed in the interior volume, the internal bellows form a seal between the center shaft and the housing. An elastic member is disposed in the interior volume and configured to apply a force that retracts the center shaft into the housing. An inlet port is configured to introduce fluid into the interior volume between the internal bellows and the housing. The fluid generates a force opposing the elastic member to extend the center shaft relative to the housing.

Systemized controls, apparatus, and mechanisms for unloading or loading portable buildings or equipment with respect to a flatbed trailer or an open, flat hauling platform are provided by a load management system. Loads such as prefabricated sheds are loaded safely without damage onto a trailer for hauling to from locations which may have hostile terrain in the vicinity of pick-up or final placement. The load management system provides a series of powered continuous tracks and lifting devices used to extend the load management system to the ground and lift the trailer until its wheels lose contact with the ground. The load management system uses powered continuous tracks to move the trailer over potentially hostile terrain to an unloading location. Conversely, the load management system can be used for loading a shed for secondary moving or repossession. During transit the load management system remains locked into a retracted safe configuration.

An airplane jack apparatus for lifting a flat main spring landing gear includes a base that supports a hydraulic jack and an upright member, to which a lift arm is pivotably attached. The lift arm has a rotatable cross member that engages a piston that raises out of the hydraulic jack, and the lift arm has a horizontal lifting portion that engages the ground-facing end of a landing gear. The base of the airplane jack apparatus has wheels to allow the jack to move as the angle of a landing gear changes while being lifted.

A conduit de-coupling device includes a supply port, a coupler for selectively engaging a connected device, a link positioned adjacent the coupler, and a disconnect port. The link is moveable between a first position in which the coupler is secured in engagement with the connected device, and a second position in which the coupler is permitted to disengage the connected device. The link is biased toward the first position. The disconnect port is in fluid communication with a fluid source to receive pressurized fluid to move the link from the first position to the second position.

A transportation apparatus is described herein that comprises a lifting apparatus having a support structure, a base portion and a scissor-lift device disposed between the support structure and the base portion. The scissor-lift device having a first arm having a first end and a second end pivotally connected to a second arm having a first end and a second end. The first end of the first arm is hingedly connected to the base portion and the second end of the first arm is slidably engaged with the support structure. Similarly, the first end of the second arm is slidably engaged with the base portion and the second end of the second arm is hingedly connected to the support structure. A method of raising centrifuge equipment to a desired height via the lifting apparatus is also described herein.
