The invention relates to a device (10) for transporting, in particular skidding or jacking, a heavy object (4) supported on at least one guide (2), comprising an actuator (7) for effecting transport, in particular at least one hydraulic cylinder, one end of which is configured for connection to the object (4) or a foundation and the other end is connected to a shoe (8) configured for connection to the guide (2). The shoe (8) comprises at least two pins (11) configured to be inserted into openings (9) in the guide (2) to provide, at least in the direction of the guide (2) a positive connection between the shoe (8) and the guide (2).

A device and method for lifting a hollow bodied block includes an elongated body having a top end and a bottom end with a handle attached to the top end. A first arm rigidly extends from the elongated body in a substantially perpendicular direction and is configured to engage an inner surface of the block. A second arm is pivotally attached to the bottom end of the elongated body in a substantially opposite direction to that of the first arm. Upon exerting a lifting force on the handle of the lifter, the second arm rotates relative to the elongated body, forming a desired angle with the first arm and creating an outward force sufficient to grip and lift the block.

A carrying device for attaching to and aiding the carrying and placement of corrugated pipe. A handle is attached to a spine having a curved grip with raised surfaces attached to each opposing end of the spine. Each of the curved grips has an open portion facing each other configured to hold a corrugated pipe. Attachments may be attached to the carrying device. A perpendicular handle may be attached providing easier carrying. Stabilizing legs may be attached providing stability when placed on the ground. A telescoping handle may be attached providing remote attachment. Carrying large cumbersome corrugated pipe is made secure and easy.

A moving assistance structure coupled to an end of a component for assisting in pushing the component into a cabinet or pulling the component out of the cabinet includes a mounting member and a driving member. The mounting member is mounted to the component. The driving member is rotationally coupled to the mounting member and includes a first abutting portion and a second abutting portion. The first abutting portion abuts the cabinet when the driving member is rotated along a first direction to push the component into the cabinet. The second abutting portion abuts the cabinet when the driving member is rotated along a second direction opposite to the first direction to pull the component out of the cabinet.

An automatic locking mechanism can include one or more annular elements having teeth facing each other or facing away from each other. The automatic locking mechanism can include a rod disposed between the annular elements. The rod can have one or more pins configured to interface with the teeth of the annular elements. The pins and the teeth are also configured to rotate the rod when the annular elements move relative to the rod. The rotation of the rod can toggle a hook end of the rod in a hook receptacle, which can change states of the locking mechanism.

A walking foot for a drilling rig comprising a foot plate attacheable to a drilling rig by an travel plate, capable of functionally bearing a load in excess a quarter of the weight of a drilling rig, comprising a planar roller array wherein a plurality of load rollers with parallel rotational axes are dispersed both laterally and longitudinally within the plane, so as to fractionalize a weight applied perpendicular to the plane, and thereby promote longitudinal motion of the roller array in a direction perpendicular to the plurality of roller rotational axes.

A pressure vessel transport system can have one or more handles that allow a pressure vessel to be efficiently and safely transported. The transport system can consist of a housing surrounding a pressure vessel with the pressure vessel having a valve. The housing may continuously extend along a longitudinal axis of the pressure vessel to position the valve within the housing.

An apparatus for assisting a user in gripping a portable electronic device has a base element adapted to be attached to the portable electronic device, wherein the base element has a top surface with an attachment region and a bottom surface configured to mount the base element onto the portable electronic device; a gripping element, wherein the gripping element has a bottom surface with an attachment region; and a stretchable cord connecting the base element and the gripping element and attached thereto at the respective attachment regions thereof; wherein the stretchable cord is sufficiently elastic to allow the gripping element to be extended away from the base element a sufficient distance for a user to insert one or more fingers between the gripping element and the base element, to grip the user's fingers when they are inserted between the gripping element and the base element, and to snap back against the base element when the user's fingers are removed, and to allow the gripping element to automatically adjust a tightness of its grip to a thickness of the user's fingers when they are inserted between the gripping element and the base element.
