Embodiments of the disclosure generally concern equipment for use in operations at oil and gas wells, particularly a structure to transport and locate large diameter electrical cables, such as those used to connect turbine generators to electric pumping units on an oil and gas well site. More specifically the embodiments of the disclosure concern methods and apparatus for transporting, positioning, and manipulating large diameter power cables at the well site of oil and gas wells with a cable transport structure using longitudinal cable retaining members to create channels to store the cables and an end rack to fold extra length of the cable back onto the cable transport structure.

A tire trolley assembly comprises a frame having a pair of supports including a first and a second support extending between a first and a second end. A connector is disposed at the first and the second end, attached to the support, extending between a primary end adjacent to the frame and a secondary end spaced from the frame. A plurality of wheels includes a first and a second wheel attached to the connector. A plurality of mounting members, including a first mounting member rotatably attached to the first wheel and coupled to the connector and a second mounting member rotatably attached to the second wheel and coupled to the connector. A traveling control system controls and steers the wheels of the tire trolley assembly.

A return device for empties includes a housing; an empties-introduction opening by way of which empties are introducible; a conveying mechanism disposed in the housing and by which empties that have been introduced can be conveyed away. The mechanism has an empties-receptacle portion facing the opening and by which the empties from the opening reach the mechanism. The portion is disposed to be adjacent to the opening and spaced apart therefrom such that a gap is present between the opening and the portion. The device further includes an optical detection device disposed in the housing adjacent to the opening, so as to be able to optically detect in an at least substantially encircling manner introduced empties; and a web extending in a region between a lower portion of the opening and the portion, to be able to serve as a bearing for the empties at least partially bridges the gap.

A device for assisting in loading heavy objects onto the load platform of a vehicle, such as a pick-up truck, comprising a frame for locating a pulling point near or above a plane established by a ramp between the load platform and the surface on which the motor vehicle is resting. The device may be provided with a roller adjacent a rear end of the load platform for reducing friction between an object being loaded and the junction of the load platform and the ramp. A pulling line capable of being extended between the pulling point and an object being loaded may be provided such that the object may be pulled up the ramp and onto the load platform, with the position of the pulling point pulling the object upwards from the plane of the ramp and load bed, such that friction between the object and the ramp and load bed is reduced.

A system and method are used for transporting a plurality of tower sections of a wind turbine on beds of transport devices, such as flat railcars. Supports affix at support locations on beds to accommodate at least one of the tower sections on each of the transport devices. The supports can include bed supports, such as tabs, extending from the beds, and can include cradle supports with slots that engage on the tabs. A circumferential dimension of a cradle is adjusted on each of the supports against which the tower section rests. Each of the tower sections is then supported with at least two of the supports by loading the tower sections on the transport devices. An end of each of the tower sections is then affixed to a flange on at least one of the supports on each of the transport devices.
