A portable tower trailer having a light tower housing constructed to allow for both stacking and nesting which is beneficial in both storage and shipping of light towers is disclosed. The portable tower trailer employs a frame having a hinged axle that allows the wheels to operate in a conventional manner. The hinged axle further allows the wheels to be rotated upward allowing the frame to rest flush on the ground or stacked upon a similar shaped portable tower. The stackable light tower is constructed having a base employing an engine system and a fuel tank; and a mast pivotally coupled to the base and movable between a storage configuration and a positioning configuration. The storage configuration is when the mast is folded over an upper surface of the base whereby an additional light tower base or tower trailer may be placed or stacked over the top of the first light tower base.

The present disclosure describes a base structural building module employing a core structural member having an array of upwardly and outwardly and downwardly and outwardly extending braces or arms extending therefrom. Tubular cans are mounted at the ends of each of the upper and lower arms to receive piles. One upper arm is aligned and paired with one lower arm and the pair's respective cans are aligned about their can axis. The modules employ flexible design by varying the lengths of the arms and their respective inclination or declination angles. Modules can be stacked one on top of another (and secured) to form multi-tiered structural building jackets for building vertical structures such as, for example, oil and gas platforms used onshore or offshore as well as other structures. Each tier can also comprise multiple modules joined laterally together to provide a wide variety of potential template configurations and building applications.

The invention relates to a load-handling means for a tower or a tower section of a wind turbine, which load-handling means has tower-attachment means for attachment to an upper end or in the region of an upper end of a tower or a tower section of a wind turbine, and attachment points for attaching at least one anchoring means of a lifting gear unit. The invention also relates to a method for erecting a wind turbine, in particular an offshore wind turbine. The load-handling means according to the invention includes at least one oscillation damper, or at least one oscillation damper is attached, in particular releasably and/or exchangeably, to the load-handling means, the damping frequency of which oscillation damper lies in the region of a natural frequency of a clamped or freestanding tower or tower section without a gondola.

Equipment for burying poles into the ground. The equipment includes a base frame associable with a machine for the movement of the equipment; a hammering assembly associated movable with the base frame and adapted to bury a pole to allow its at least partial penetration into the ground at a burying position; and a gripping and positioning assembly of the pole, associated with the base frame and adapted to grasp the pole and to position it under the hammering assembly at the burying position.

A method for refurbishing a wind turbine includes removing an existing machine head from the wind turbine, and providing a new machine head and an adapter. The new machine head includes a base frame, and further includes a plurality of fastener holes defined in the base frame. The adapter includes an outer sidewall and defining a first plurality of fastener holes and a second plurality of fastener holes, the first plurality of fastener holes disposed in a first hole pattern, the second plurality of fastener holes disposed in a second hole pattern different from the first hole pattern. The method further includes connecting the new machine head and the adapter such that the adapter is connected to and between a yaw bearing and one of the base frame or a top flange of a tower of the wind turbine.

A pipe handling apparatus includes a lower mast, upper mast, and trailer. The lower mast and upper mast may be pivotably coupled at a hinge point. The trailer may be coupled to the lower mast by a hydraulic cylinder. The pipe handling apparatus may be transported to a drilling rig and the lower mast mechanically coupled to the drilling rig. The upper mast may be pivoted relative to the lower mast at the hinge point. The lower mast and upper mast may be pivoted from the horizontal position to the vertical position by the hydraulic cylinder.

A portable and modular foundation that can be utilized to support a monopole includes a central hub and a plurality of legs. A proximal end of each leg is removably attached to the central hub. A plurality of floor panels extends from proximate the hub to a perimeter of the foundation and define a substantially uninterrupted floor. With the plurality of floor panels attached to the legs, the foundation can optionally be buried where the soil or other material is positioned on top of the floor panels to provide the necessary ballast to allow the foundation to retain a monopole with a piece of equipment in an elevated position. Alternatively, if the foundation is to be utilized above ground, a plurality of wall panels can be attached to the floor panels and the legs with braces to retain the wall panels in a substantially vertical position. The plurality of wall panels forms a substantially continuous wall about a perimeter of foundation such that ballast can be placed therein.
