  • Patent number: 9651021
    Abstract: The present disclosure is directed to a system and method for lifting and/or removing a rotor blade to and from a wind turbine. In one embodiment, the system includes an up-tower pulley mounted on an up-tower location of the wind turbine, first and second ground winches, a pulley cable from the first ground winch over the up-tower pulley and attached to the rotor blade, a guide line attached between an up-tower location of the wind turbine and the second ground winch, a guide pulley mounted on the guide line, and a guide cable from the guide line over the guide pulley to the rotor blade. Thus, the guide pulley is configured to move along the guide line during lifting and removing of the rotor blade so that the guide cable can control an orientation of the rotor blade relative to the tower during lifting and removing of the rotor blade.

  • Patent number: 9272166
    Abstract: A movable cable loop descent system comprises a cable for forming into a loop, a receiver for attachment to a structure having a receiver pulley for engaging the cable loop, a brake assembly, having a drive pulley for being rotated by the cable loop, the brake assembly for slowing a rate of travel of the cable loop and a carriage supporting a load for attachment to the cable loop at a point and for movement between the structure and the ground. A rotor and substantially parallel conductive frame is mounted on an axle through the drive pulley. Magnets on a surface of the rotor and/or the frame induce eddy currents, as they are relatively rotated, which create a rotational braking force controlling descent of the carriage and load. The brake assembly may be removably positioned by a drive-on anchor. The cable is removable and the system may form a kit.

  • Patent number: 8807292
    Abstract: Improvements in a braking system for a zip line are presented. Braking occurs when a zip line rider makes contact with a braking carriage that slides along the zip line. The braking carriage pulls on a rope. The rope pulls on a length of chain in a chain reservoir to slide and lift the claim through the chain reservoir. The chain reservoir is an elongated tube that is mounted at an angle. As the zip liner moves further into the landing platform they lift a continuing greater amount of chain from the chain reservoir. The angle of the chain reservoir, coefficient of friction between the chain and the chain reservoir affects the pull-back. After the zip liner comes to a complete stop they remove the carriage from the zip line and gravity returns the brake mechanism. Minimum pull-back makes removal of the cable trolley easier.

  • Patent number: 8556234
    Abstract: A single cable descent control device comprises a pair of rotors with corresponding frames of conductive material mounted on a common central axle on either side of a drive pulley. The pulley is adapted to sit above a single descent cable. An enclosure is suspended from the device. Disposed along at least one surface of each of the rotors or of the corresponding frames or both, is a series of magnets such that rotation of the rotors relative to the frames induces eddy currents that oppose the magnetic field and create a rotational braking force providing precise and controllable descent of the enclosure with little or no mechanical wear or risk of overheating. In this configuration, constraints on the size of the enclosure are dispensed with, as are corresponding limitations on the positioning and angle of descent of the cable. Further, significant labor and material savings in manufacturing the enclosure may be obtained from the resulting simplicity of design.

    Abstract: A supported davit arm extension assembly for a descent apparatus comprising an escape shuttle suspended from a cable defining a descent path from an initial point at a receiver of a platform to a terminal point proximate to a ground surface. The extension assembly comprises a davit arm extending above the platform and secured to the receiver, and a fall arrest trolley operatively coupled to the shuttle at a first end and terminating at a second end extending substantially away from the terminal point. The second end of the fall arrest trolley has a securement point for connection to and support of a load, such as a worker, by an overhead fall arrest. While the shuttle is docked with the receiver, the fall arrest trolley extends over the platform, supported by the davit arm, and facilitates substantially unfettered movement of the worker around the platform. As the worker enters the shuttle, it is disengaged from the receiver and follows the descent path of the cable toward the ground surface.

    Abstract: A safety system which permits the free movement of the user, assists the ascent of the user and provides a reduced, controlled rate of descent in the event of an emergency descent or a fall, includes a cable attachable at one end to the user and secured at the other end to a moveable counterweight assembly. Intermediate its ends the cable passes over a pulley in a controlled descent device which also includes a centrifugally-actuated clutch coupling the pulley to a speed-multiplying gearing system and a centrifugally-operated braking assembly. Under normal-use conditions, the pulley is rotated at sufficiently low speeds to preclude engagement of the clutch, and the user has free movement, with a component of the counterweight assisting the ascent of the user. In the event of a rapid rate of descent, the increased rotational speed of the pulley is coupled to and actuates the braking assembly to reduce the rotation of the pulley and slow the descent to a lower, controlled rate.

    Abstract: An escape device for allowing an endangered person to be safely lowered from a drilling tower or other elevated structure includes an automatic brake which controls the descent of a trolley assembly downwardly along an escape cable extending from the elevated structure to a ground level anchor remote from the structure. The automatic brake includes a reel rotatably secured to the elevated structure and a brake cable wound about the reel and attached at one end to the trolley assembly. A fluid pump coupled to the reel causes the reel to rotate at a constant speed when the trolley assembly descends the escape cable. The effective diameter of the reel decreases as the brake cable is unwound therefrom, thereby slowing the rate of descent of the trolley assembly as it approaches the lower end of the escape cable. The escape device is adapted to be used with both the upper and lower stations of a derrick or similar elevated structure.

  • Patent number: 3970287
    Abstract: A guide block of the open breach type particularly adapted for use in connection with a vertically disposed cable. The guide block includes two U-shaped hand plates fixed in parallelism relative one to the other, the plates being separated one from the other a distance at least slightly greater than the diameter of the cable. Each hand plate is provided with a hole centrally thereof, and a slot extending from that hole to one edge thereof. The hole diameters are each substantially greater than the cable diameter, and the slot widths are each only slightly greater than the cable diameter. The hand plates are oriented relative one to the other so that the holes are concentrically disposed, and so that the slots face in opposite directions one from the other. The hand plates are fixed relative one to the other so as to define a mouth which provides access to the two slots for a cable.
