A pipe replacement system and cable guide frame are shown. Configurations are shown that include plurality of guide pulleys attached to the cable guide frame to define a curved path between a pipe to be replaced and a cable pulling system. Configurations are shown where a pipe breaking tool is pulled over the plurality of guide pulleys for ease of removal after a replacement operation. Configurations are also shown that include a stationary splitter adjacent to the cable pulling system to prevent jamming of the cable pulling system.

A method for creating a composite cable having at least one advanced termination on at least one end. An advanced termination is added to an end of a short synthetic tensile strength member. The strength of the tensile strength member and termination is then tested. Once tested satisfactorily, the short cable is spiced onto a long cable of the same type using prior art splicing techniques. The union of the short cable and the long cable creates a “composite” cable having a advanced termination on at least one end. In most applications it is preferable to set the length of the short cable so that the interwoven splice will exist at a desired location.

A power pack is located within a housing on the platform of a wind turbine generator tower. The power pack is supplied from a fuel tank. With the door of the housing open, the power pack may be removed for servicing and repair by using a U-shaped support structure to which an electric motor is mounted. Two support rails permanently located within the housing support the housed power pack. A chain attached to the power pack is driven by the motor to remove the power pack from the housing by sliding the power pack along the support structure. A pulley arrangement reduces the necessary torque. After removing the power pack from the housing, a crane is used to lift the power pack from the platform and to lower it down to a sea vessel. The crane may also be used in the refilling of the fuel tank by hauling a fuel line from a sea vessel up to the platform and connecting it to the fuel tank.

An apparatus for use with a sheet of rigid support material at a hole formed therein through a thickness of the sheet to provide an anchoring point at a proximal face of the sheet for anchoring an object thereto comprises a frame member supporting a face-engagement member for engaging a distal face of the sheet which is spaced from the proximal face by the thickness of the sheet, so as to resist removal from within the hole by the object anchored to the apparatus, and a buttress member also supported on the frame member for buttingly engaging a peripheral wall of the hole so as to resist movement transversely to a thickness direction of the sheet.

Provided herein is a balanced locking pawl. In particular, the center of gravity of the locking pawl is located at or near the pivot point of the locking pawl. The balanced approach allows for a faster locking response during the rebound (whiplash/return) forces of a crash.

Provided herein is an electronically-controlled wheelchair securement system with a winch apparatus that is adapted for pulling and steering a mobility device (e.g., wheelchair, scooter, stretcher, etc.) up and down the ramp of a rear-entry wheelchair accessible vehicle and for providing securement for the mobility device during transport.

A crawl space winch system including a base plate; a winch box carried by said base plate; a winch mechanism disposed in said winch box and having a cable extending out of an opening in a front side of said winch box for attaching to an item; a winch drive shaft extending through a sidewall of said winch box and being operatively associated with said winch mechanism for retracting said cable; and, a primary anchor opening disposed in a generally central portion of said base plate for receiving a portion of a primary anchor to secure said base plate to the ground, and wherein said primary anchor provides a pivot point around which said base plate rotates.

A machine for extracting a ductile pipe. The machine has a vise which can grip the pipe, and a wire clamp. Each of the wire clamp and vise are supported on a carriage which is movable relative to a frame. This enables the vise to grip and pull the ductile pipe. Additionally, a wire strand may be disposed through the pipe from a far end to the end at which the machine is placed. The wire clamp allows the machine to pre-stress the strand to improve the extraction of the ductile pipe.
