Abstract: The present application relates to a substrate transfer device, comprising a horizontally arranged cross beam, and support beams longitudinally arranged at two ends of the cross beam, wherein a substrate carrier is suspended on the cross beam, the substrate carrier is located between the two support beams, and the substrate carrier is parallel to a plane where the two support beams are located, the substrate carrier comprises two side walls oppositely arranged in a horizontal direction, and each of the support beams is provided with an auxiliary clamping structure for clamping the substrate carrier during transferring of the substrate carrier.

Abstract: A vertical pipe handler with pivoting arms for a drilling rig can include a central support and a central support center line. The vertical pipe hander can grab a tubular with top and bottom pipe grabbers, and lift the tubular using a bottom non-rotating collar and a bottom rack and bottom pinion lift mechanism. The tubular can be vertically positioned before being moved downward; thereby allowing for a next tubular in a series to be positioned and inserted.

Abstract: A pipe-handling system includes at least two pipe-handling units arranged in a vertically displaceable manner along respective guide tracks of, respectively, first and second portions of a tower. The pipe-handling unit is provided with lower and upper rotary units spaced apart vertically on a chassis. Each of the rotary units is provided with a rotatable tong and a hanging-off device. A method is for inserting and withdrawing a pipe string in/from a borehole by the use of the pipe-handling system.

Abstract: A pipe handling system includes a pipe stabilizer for receiving a pipe as lateral movement of the pipe is controlled by a guide system. The end portion of the pipe stabilizer may include a magnetic member configured to releasably couple to the pipe. The end portion of the pipe stabilizer may be extended and retracted by a rotatable arm. The end portion of the pipe stabilizer may be moved by an adjustment mechanism relative to another portion of the stabilizer or a drill string at well center for fine tuning placement of the pipe.

Abstract: A system usable with a pipe laying vessel, includes a support frame, such as a deck frame of the vessel, and a loader arm which is movable between a loading position and an upright position. The loader arm is provided with a pipe section manipulation system. A first clamping member is provided having a substantially fixed position with respect to the support frame. The first clamping member is operable between a clamped position for supporting the weight of the pipeline, and a released position for allowing the pipeline to be lowered. A second clamping member is movable between an upper position and a lower position. The second clamping member is operable between a clamped position for supporting the weight of the pipeline during movement from the upper position to the lower position, and a released position for moving the second clamping member from the lower position to the upper position.

Abstract: A tray is provided for orienting and conveying items having a longitudinal axis, a tip, an opposite head, and a head-up and a head-down orientation, the tray conveying the items in a direction of travel and including a series of connected, function-oriented static regions configured for orienting the item from a random orientation to a desired tip-down orientation, at least one of the regions being inclined for facilitating movement of the item through the regions, the regions being configured such that proper orientation of the item is achieved without operator contact.

Abstract: The present invention relates to a tubular handling system (1) comprising: -a tower (10) comprising a tubular lift device for lowering and/or raising a tubular in an essentially vertical orientation, -a support (20) for supporting the tubular-laying tower -a tubulars supply system, preferably provided on the support, for supplying tubulars 26 to an essentially horizontal supply position in the vicinity of the tower, -a tubular handling apparatus (2) for transporting a tubular between the essentially horizontal supply position and the tubular lift device in the tower, wherein the tubular handling apparatus comprises: a gripper (4a, 4b) adapted for gripping the tubular, a base (6), and a boom (5) to which the one or more grippers are attached, which boom is pivotable with respect to the base in a boom.

Abstract: A tube picking mechanism is designed for use in an automated, ultra-low temperature (e.g. ?80° C. or ?135° C.) or cryogenic (e.g., about ?140° C. to ?196° C.) storage and retrieval system that stores biological or chemical samples. The samples are contained in storage tubes held in SBS footprint storage racks that are normally stored within an ultra-low temperature or cryogenic freezer compartment. The tube picking mechanism includes a tube picking chamber that is maintained at about ?80° C., about ?135° C. or at cryogenic temperatures in cryogenic applications. Active electrical and mechanical components are maintained in a compartment above and separate from the refrigerated, ultra-low temperature or cryogenic compartment.

Abstract: A power tong positioning apparatus having a base section and a backup elevating section engaging the base section. A first lift assembly is positioned between the base section and the backup elevating section while a tong elevating section engages the backup elevating section. A second lift assembly is then positioned between the backup elevating section and the tong elevating section.

Abstract: Apparatus for gripping and lifting objects such as fence posts. A frame carries a pair of grippers that are slidingly movable along the frame to grasp a post or other object. The grippers may pivot so that the object remains in essentially constant vertical orientation despite arcuate motion of a tractor or other lifting machine by which the frame is lifted. The grippers may be actuated by hydraulic or other power provided by the lifting machine.

Abstract: A pole extractor having a base and a hydraulically operable cylinder and ram assembly. The base is coupled to an attachment means to define a slot for accepting a mobile positioning device. The cylinder and ram assembly have a proximal end coupling said assembly to the base. The ram has a distal end remote from the base, which has a connecting means to accept a holding means. In use, the holding means releasably holds a pole. The cylinder and ram assembly has a fluid inlet and a fluid outlet to communicate with an actuating means that controls extension of the ram within the cylinder, which in turn extracts the pole. In use, a pole is choked to the ram and the ram is actuated in order to extract the pole from a substrate.

Abstract: Concentric, tubular sections are assembled by first securing annular centralizers and insulation about the external surface of the smaller diameter tube while the tube is horizontally disposed. The larger tube is then vertically aligned and lowered into a recessed area formed below the assembly area work level. A lifting cable, secured at one end to a lifting device, is extended through the smaller diameter tube and attached to a hoisting arrangement that vertically orients the tube concentrically over the larger diameter tube. Spring-loaded legs on the lifting device are manually retracted radially to permit the smaller tube to be lowered concentrically through the larger tube. The inner tube is lowered until the legs spring radially outwardly to engage the base of the larger tube. The entire assembly may then be lifted as a unit by the hoist with the lifting device, establishing the axial positions of the two tubes relative to each other.
