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.

Disclosed is a pusher lift cart comprising a pusher lift cart main frame having a first interfacing member and a second interfacing member configured to telescoping engage a first complementary interfacing member and a second complementary interfacing member, wherein the pusher cart main frame is configured to receive and move an axle.

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.

Examples include systems and methods for lifting and moving gondolas using a modular gondola moving system. Components of a modular gondola moving system include interchangeable skates. The interchangeable skates are further removably attached to a longitudinal member which, when connected to the longitudinal member, form a skate system. Multiple skate systems are positioned to the underside of a gondola and may additionally be connected together by connector bars for stabilization and to form the modular gondola moving system. One or more lifting devices are provided independent of and are used in combination with each skate system for positioning the gondola on each skate system. The one or more lifting devices may be repeatedly used in order to place the gondola on a single modular gondola support system.

A reusable handling device is specially designed for transporting components of a checkout station to a location within the store where the checkout station is installed. The handling device includes casters and is designed to removably mount to a checkout station component (e.g., bagger) having adjustable feet when there is a need to move or transport the checkout station component (e.g., during installation). Generally, the handling device is configured to extend between and engage two of the adjustable feet of the checkout station component. Two or more handling devices can be mounted to the checkout station component to move the checkout station component during installation and can be removed when finished. After the installation is complete, the handling devices can be returned to the manufacturer or supplier of the checkout station component for use in another installation.

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 hand truck having a plurality of hingeably engaged sides that is expandable from a closed position dimensioned to fit through a standard doorway, to an open position to form a movable platform having a swing out support frame having an upper end hingedly attached to the rear side of the center frame which is movable between an extended position and a stored position. A corresponding sofa dolly and a platform enclosure is also disclosed.

A portable cart has a frame assembly having a front end, a rear end, and a plurality of vertical beams. A front leg assembly having a pair of extendable front legs is secured adjacent the front end of the frame assembly, and a rear leg assembly having a pair of extendable rear legs is assembly secured adjacent the rear end of the frame assembly. A table top is secured to the frame assembly.

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.

The present disclosure is directed to battery cart for transporting large and heavy electric car batteries. The cart includes a pair of independently movable and positionable cart half assemblies, with each cart half assembly having a pair of battery supports that are slidably positionable and lockable along a center crossbar. Each support includes height adjustable columns. The cart assemblies therefore, are adjustable to support batteries of varying sizes as well as positioning a supported battery to desired height, facilitating repairs to, and transport of, the electric car battery.
