A wind turbine blade handling apparatus for rotating and lifting a blade. The apparatus includes a root device having a root support member with a concave upper surface and rollers having a longitudinal axis parallel to the longitudinal axis of the blade and configured to rotate the blade; a base, and a scissor-lift mechanism with intersecting struts which converts from a lowered position wherein the struts are disposed in a generally coplanar configuration, to an elevated position wherein the struts are disposed in an angled configuration.

A wind turbine blade apparatus comprising a root device including: a base having an upper surface with a radius of curvature and configured to receive a root portion of a blade, with housings disposed on lateral sides of the base. The housings including a groove configured to receive a bearing and a shaft extending at least partially through the base and housing. A tip device is also provided which includes a base, a rotatable support frame having: a first support configured to receive a pressure side of a wind turbine blade, a second support configured to receive a suction side of a wind turbine blade, and an opening, the opening configured to receive a portion of a wind turbine blade.

A wind turbine blade suspension and rotation device capable of raising and lowering the blade includes a blade housing configured to receive a blade and having at least one guide on an exterior surface; a base; a first telescopic frame disposed on a first side of the base; a second telescopic frame disposed on a second side of the base; at least one adjustable strap, the adjustable strap disposed between the adjustable frames; wherein the at least one strap extends through the guide on the exterior surface of the housing to suspend the blade.

Embodiments are directed to improving transportation of tubular structures. A roller may have a housing having a vertical axis and one or more upper flanges. The one or more upper flanges may have an upper surface that is transverse and non-perpendicular to the vertical axis of the housing. Optionally, the upper surface may be curved. The roller may have one or more wheels that are rotatably coupled to the housing and that extend downward from the housing.

An assembly includes an attachment arm having an axle extending from a first end of the attachment arm. The attachment arm of the detachable wheel assembly further includes a securing portion forming a second end of the attachment arm, the securing portion of the attachment arm including a pin positioned to extend above a first frame member of a gantry truss and to secure the first frame member between the pin and a portion of the attachment arm. The attachment arm also includes a frame support corresponding to a second frame member of the gantry truss such that the frame support supports the second frame member when the assembly is secured to the gantry truss, and the assembly includes a wheel rotatably attached to the axle of the attachment arm.

A pair of dollies for storing and transporting scaffold frames is disclosed. Each dolly is made up of two identical dolly members containing a top plate, bottom plate, two side plates and a front and back plate. Communicating holes are inserted along the length of the top and bottom plates. The side plates of each dolly member has semi-circular cut outs on the top edges which correspond with the holes in the top and bottom plates. The end holes at the front and back of each dolly member have tubes permanently inserted to receive a typical scaffold 8 inch swivel caster wheel with brake. Scaffold frame legs are inserted into the remaining holes in the top and bottom plates of the dollies. The bottom cross member of each scaffold frame sits on the semi-circular cut outs on the top edges of the side plates. This device can be used for storage or transportation of scaffold frames.

A set of two two-wheeled dollies, each of which has a cradle, preferably V-shaped, is configured to support a length of pipe or other elongated construction material. The dolly set consists of a steerable forward dolly, having a steering handle, and a non-steerable rear dolly. The two dollies are deployed in tandem, with the forward dolly supporting the front end of the load, and the rear dolly supporting the load's back end. By turning the handle bar of the forward dolly in a selected direction and applying a force in that direction, the tandem paired dolly set moves the elongated load in the selected direction.

A pallet is provided for supporting cylinders. The pallet can have a convex spine extending substantially the length of the pallet in a longitudinal direction, having a backstop at a first end. The pallet has one or more trays attached transverse to the convex spine, each tray having longitudinal fluted indents to restrain a cylinder from rolling transverse, the longitudinal fluted indents are each arranged to accept a cylinder from above. The pallet has a left outrigger attached and extending transverse to the convex spine, the left outrigger stabilizing the pallet with respect to terrain, as well as a right outrigger attached and extending transverse to the convex spine, the right outrigger stabilizing the pallet with respect to terrain. The pallet can have a coupling extending from an end of the convex spine, wherein the coupling is arranged to take a crane hook in engagement to pull the pallet.

A transport system includes a trailer with a transport bed adapted to receive a shelter having substantially rectangular base with approximate bottom dimensions of a standard International Organization for Standardization (ISO) freight container; first and second wheeled transport assembly positioned on the trailer, wherein each transport assembly is adapted to connect to each end of the shelter to move the shelter on or off the trailer; and base locking units at each corner of the bed to be secured to a shelter.

An apparatus including a platform, casters attached to the platform, and a carriage supported by the platform is described. The carriage includes a left arm, a right arm, and an actuation mechanism. The left arm can pivot about a left lateral axis, and the right arm can pivot about a right lateral axis. The actuation mechanism allows a distance between a proximal end of the left arm and a proximal end of the right arm to be modified. Increasing the distance causes a distal end of the left arm and a distal end of the right arm to swing towards each other. Decreasing the distance causes the distal end of the left arm and the distal end of the right are to swing away from each other. The apparatus provides a convenient means by which to move a helicopter equipped with skids while the helicopter is on the ground.
