A mast (10) which includes an elongate post (12) with a first end (14) and a second end (16), the first end (14) being pivotally secured to a ground-engaging support base, at least a first mechanism (22) to restrict pivotal movement of the post (12), a winch (26) which is attached to the post (12), and a cable (28) which is engaged with the winch (26) and which is secured at one end to an anchor (30), wherein the winch (26) is actuable to allow the post (12) to pivot, from an elevated position, in a first direction (54) which lowers the post (12) against the action of the movement restricting first mechanism (22), and which is actuable to pivot the post (12) in a second direction (56) which opposes the first direction (54) to elevate the post (12).

This invention discloses a tower system in which a telescoping tower with a plurality of tower structures is contained within a rigid transportation container in a substantially horizontal position for transportation, may be extended to a height much greater than its contracted length. The tower may be transported horizontal, repositioned to a vertical position and then the individual tower structures extended and secured via spring pins relative to the adjacent tower structure, the erection of the tower sections may be with external equipment such as a boom truck, or utilizing an internal hydraulic cylinder.

A portable wind turbine is adjustable between an operating configuration and a stowed configuration. The portable wind turbine comprises a turbine tower and a base. The base includes a floor and a pair of opposing sidewalls. The base includes four lower corners. The base is configured to store the turbine tower when the portable wind turbine is in the stowed configuration. The turbine tower is oriented in an upright manner such that the turbine tower projects upwardly away from the floor of the base when the portable wind turbine is in the operating configuration. An outrigger is attached at each of the four lower corners of the base when the portable wind turbine is in the operating configuration.

A system and method for pulling a cable. The system includes a cable which has at least one button located along its length. A cable puller is coupled to the cable and has at least one slot for receiving the cable. The cable puller also has a plate for engaging the button. The cable puller has a sleeve with an upstream end and a downstream end, and the plate is located on the upstream end. The plate prevents movement of the button upstream of the plate.

A modular pipe brace assembly is provided for supporting a concrete wall panel, where the modular pipe brace assembly has a plurality of brace sections that each have a pipe with one of at least two standard lengths and a connection plate attached to each end of the pipe. At least two of the plurality of brace sections are attached together in longitudinal alignment by engaging the connection plates to define a pipe assembly with a desired length. An adjustable shoe assembly is attached to each end of the pipe assembly and is configured to engage a ground anchor or a concrete wall panel. The plurality of brace sections may, for example, include a low-load brace section that has a low-load capacity pipe and a high-load brace section that has a high-load capacity pipe.
