  • Patent number: 8640388
    Abstract: A support structure for a rostrum includes a first A-frame; and at least a second A-frame, nestable and retractable into the first A-frame. The support structure may have an open central area and the second A-frame may be substantially the same as, but smaller than, the open central area of the first A-frame. At least one support means is connected to each A-frame for supporting a load, wherein the support is connected to an upper portion of one A-frame. The support extends from the upper portion of the one A-frame and is co-operable with an upper portion of another A-frame. The support structure may be telescopic and configured to be expandable and retractable between a retracted, stored position, and an extended, in use position.

    Abstract: Disclosed herein is a telescoping substructure of a drilling rig that includes first and second telescoping substructure boxes. The first and second telescoping substructure boxes each include, among other things, a lower substructure box and an upper substructure box that is adapted to be telescopically raised and lowered relative to the lower substructure box. Furthermore, each telescoping substructure box also includes raising means for telescopically raising and lowering the upper substructure box relative to the lower substructure box between a collapsed configuration for transportation and a raised configuration for drilling operations, wherein each of the first and second telescoping substructure boxes are adapted to facilitate movement of the telescoping substructure in at least one of a lateral direction and a longitudinal direction over wellhead equipment positioned above a wellbore location when the upper substructure boxes are in the raised configuration.

  • Patent number: 8534004
    Abstract: A rapid deployment and retraction telescoping mast system for controlling the height of a mast. A retraction mechanism including a resilient member, a retraction reel, a reel shaft, and a motor disposed about a frame. The resilient member extends from the retraction reel and is rigidly attached to a top tube of the mast through a sealed passage. The reel shaft rotates the retraction reel and winds the resilient member creating a retraction force on the top tube causing controlled retraction of the mast. A deployment mechanism including a compressor, storage tank, exhaust valve and isolation valve arranged about the frame and in communication with the mast. The compressor generates pressurized air to be communicated to the mast when the isolation valve is in the open position. The increase of pressure generated by the deployment mechanism provides a force within the mast thereby controlling its deployment.

  • Patent number: 8474221
    Abstract: An environmentally friendly fiberglass utility pole that comes in three sections that are telescoped one around the other to provide a strong, wind and bending resistant structure. Each of the three sections has alternating protruding and intruding surfaces that are slip fit together to provide maximum strength while conserving material. Additionally, each of the three sections preferably are different lengths such that maximum reinforcement is provided along the center of the length of the pole, without requiring excessive material (or weight) at the top end of the pole.

  • Patent number: 8381460
    Abstract: An extendable beam has compact slideable segments with angular extensions connected by cables which are tensioned to strengthen the beam when the beam is extended by sliding the segments. Restraining parts slide along tracks on neighboring segments. Short fixed length cables are connected between tips of extensions and diagonally between extension tips and segments are tensioned when hinged extensions are deployed. Other cables are paid out and tensioned, connecting tips of extensions on adjacent segments. Internal pulleys and beam extension cables simultaneously slide adjacent segments to extend the beam. An external crane and lock extend the beam serially.

  • Patent number: 8375649
    Abstract: The subject matter of the invention relates to a support arm for a lifting platform, comprising at least one relatively wide support arm and an extension arm telescopically slidable therein, the arms each having torsionally rigid and flexurally stiff hollow profiles, a support bearing at the rear end of the accommodating arm for the pivotable hinging connection to a lifting carriage of a column and a bearing foot at the free end of the respective extension arm. A cost-effective production of support arms in different sizes and shapes is obtained by cutting at least the accommodating arm from a steel panel blank and forming it into a hollow profile and providing it with at least one transverse reinforcement.
