A rig movement, rotation and alignment assembly. A plurality of lifting jack assemblies are provided, each of the lifting jack assemblies attached to a rig substructure. Each of the lifting jack assemblies has a cylinder housing and a rod movable axially within the cylinder housing. Each rod is engaged with a screw drive in order to rotate the rod with respect to the cylinder housing. Each rod includes a circumferential recess wherein the circumferential recess includes at least one flat segment. A retainer plate attached to each bearing pad is received in and engaged with the circumferential recess and with the flat segment, so that rotation of the rod results in rotation of the bearing pad.

A hand held jacking/levelling-tool is provided comprising a jacking shaft and a frame moving relative to each other during jacking action, a caulking gun jacking mechanism providing the jacking action, two outer legs fastened to one of the frame and the jacking shaft and one middle leg fastened to the other of the frame and the jacking shaft being positioned between a left and right outer leg. Furthermore the jacking/levelling tool comprises a foot fastened at a right angle to each leg and pointing in the same direction. The jacking action causes the jacking shaft to move downward through the frame.

A system, apparatus, and method for leveling a borehole or blasthole drilling machine, or portion thereof, provided over a drilling site can implement a ground contact detect phase or operation, a first coarse leveling phase or operation, a lowering phase or operation, and a fine leveling phase or operation. The phases or operations can be based on or responsive to signals from sensors of the drilling machine. The phases or operations can involve changing length of one or more of the jacks of the drilling machine when the drilling machine is positioned over the drilling site.

An inflatable air wedge has a tool channel that is inserted between a vehicle door and a vehicle body for allowing an operator to effectively unlock the vehicle door without damaging the vehicle (door and/or body and/or weather stripping). The inflatable air wedge includes a selectively inflatable bladder capable of being intercalated between the existing vehicle door and the existing vehicle body, a pneumatic mechanism in operable communication with the bladder for selectively introducing and releasing air from the bladder, and a conduit engaged with the bladder. Advantageously, such a conduit is suitably sized and shaped for guiding an existing unlocking tool therethrough while the bladder is at an inflated state and seated between the vehicle door and the vehicle body. Notably, the conduit is spaced from the pneumatic mechanism and manually distended when the unlocking tool is positioned therein.

The disclosure discloses a wheel blank discharging position detecting device which comprises a frame, wherein a clamping system, a detecting system and a positioning system are arranged on the frame, and the detecting system comprises a distance sensor arranged on the frame above the clamping system; the positioning system comprises a detector arranged on the frame, and the device is simple to operate and improves the machining yield.

Pumping machine (650, 750) comprising: at least two tubular elements (651, 751) containing pressurized gas and extending vertically in parallel and interconnected between them by means of a connecting element (652, 752); andan electromechanical lifting system (600, 700) comprising a first cylinder (601, 701), interconnected to the tubular elements (651, 751) and comprising a substance compressible by a piston (601b, 701b); and a screw (602, 702) with a vertical axis Y coinciding with the axis of the pumping machine (650, 750). The screw (602, 702) is inserted inside a second thrust cylinder (658, 758), connected in sliding manner inside the first cylinder (601, 701), and has a first end (602b, 702b) fixed to the connecting element (652, 752) and a second end (602a, 702a) configured for sliding inside the thrust cylinder (658, 758) and overlying a chamber (605, 705) comprising lubrication and cooling oil overlying the piston (601b, 701b).

A vehicle lift system incorporating one or more lift control modules having an advanced operating platform. The lift control module includes a user interface for receiving user instructions from a user, at least one control module processor, and a non-transitory computer-readable medium with an advanced operating platform stored thereon. The computer readable medium includes a first application operable executable by the advanced operating platform. The first application directs the control module processor to provide instructions to the vehicle lift to control the vehicle lift based on the user instructions. The computer readable medium further includes a second application executable by the advanced operating platform. The second application directs the control module processor to perform certain steps, with such certain steps not directed to controlling the vehicle lift. Furthermore, the advanced operating platform is configured to execute said first application and said second application simultaneously.
