A universal quick-release anchor member includes a flexible base seal member comprising non-porous resilient material. The base seal member is configured to engage an external reference surface and form a substantially airtight seal therewith that defines a controlled pressure zone. A vent port extends through the anchor member. A vent port closure member is disposed proximate to a vent port upper end. The vent port closure member is biased to move from a closed position to an open position. The closed position includes the vent port closure member being arranged to block the vent port upper end and prevent the passage of air through the vent port. The open position includes the vent port closure member being arranged to unblock the vent port upper end and allow the passage of air through the vent port.

Various embodiments illustrated herein disclose a leveling foot tool which comprises a first base and a threaded rod. The threaded rod comprises a cavity to insert a screw nut and bolt assembly. A socket driver is installed over the screw nut and bolt assembly. The leveling foot tool is mounted on a drill. The first base of the leveling foot tool has one or more holes through which one or more screw nut and bolt assemblies are threaded. A leveling foot, which is to be installed comprises a second base and a threaded rod. The second base of the leveling foot comprises one or more holes to receive the one or more screw assemblies of the leveling foot tool. Using the rotational and the translational motion of the drill, the threaded rod of the leveling foot is drilled into a threaded hole of a leg of a machine.

A method and an apparatus for isolating a vibration of a positioning device are provided. The apparatus includes a base plate for the positioning device, at least one active bearing element for bearing the base plate on/at a foundation and at least one evaluation and control device. The apparatus includes at least one means for determining a foundation movement-dependent quantity, wherein the active bearing element is controllable by the at least one control and evaluation device on the basis of the foundation movement-dependent quantity.

A vehicle support structure, which in petroleum wellsite operations is commonly called a rig mat or a ground stabilizing mat, includes: a main body including an upper surface, an underside, a front end and a rear end, the main body defining a planar structuring with a thickness; a front pad coupled to the main body and positioned adjacent the front end; a rear pad coupled to the main body and positioned adjacent the rear end, the front pad and the rear pad each configured to be moveable between a supporting position protruding from the underside of the main body and a retracted position in plane or retracted from the underside; a front pad drive mechanism for the front pad, the front pad drive mechanism configured to drive the front pad to move between the supporting position and the retracted position and to move the front pad forward and backwards and side to side relative to the main body; and a rear pad drive mechanism for the rear pad, the rear pad drive mechanism configured to drive the rear pad to move between the supporting position and the retracted position and to move the rear pad forward and backwards and side to side relative to the main body, the front pad and the rear pad being configured to operate to support the main body in an elevated position relative to a ground surface and configured to move the main body forward and backwards and side to side relative to the front pad and the rear pad and over the ground surface. In use as a rig mat, a method for well site operations includes: placing the rig mat at a position on a first well site; positioning a rig on the rig mat; and adjusting the position of the rig mat while the rig remains supported on the rig mat such that the rig is centered on a wellhead of the well site.

The present disclosure provides a support for household appliance and a household appliance, the support for household appliance comprises a hydraulic plate, which is fixed to the bottom of the household appliance; a sheath, which is fixedly connected with the hydraulic plate; a regulating support, which is arranged in the sheath and is axially movable relative to the sheath; an accommodation chamber, which is formed by the hydraulic plate, the sheath and the regulating support; and a flexible accommodation body, which accommodates a liquid medium and is arranged in the accommodation chamber. The flexible accommodation body extends and retracts to drive the regulating support to axially move in the sheath for leveling under the action of pressure. The hydraulic plate is locally embedded inside the sheath, thus, the overall height of the support for household appliance is reduced while the overall strength of the hydraulic plate is guaranteed.
