A method including measuring a distance between two successive supporting poles delimiting a section to be realized, inputting data into a computer programmed to output a layout plan indicating a position and a length for each dropper to install, preparing each dropper with a dedicated machine, moving a first platform along the section, which is equipped with a position unit and a marking device to set a mark on the contact wire at each position where a dropper is to installed, moving a second platform along the section, the second platform being loaded with the droppers that have been prepared, and fixing manually each dropper between the messenger wire and the contact wire in registration with a corresponding mark set on the contact wire.

A hanging arrangement for items of electrical operating equipment includes an upper fastener for suspending the hanging arrangement, a plurality of items of operating equipment being arranged so as to hang in a parallel manner from the upper fastener, and a lower fastener which is arranged so as to hang from the items of operating equipment. The items of operating equipment are connected to the fasteners in each case by flexible contact device.

A cable clamp for clamping drop cables to main span cables. The cable clamp has a frame, a jaw assembly and a stem. The frame has a main body, a drop cable body and a main cable body. The jaw assembly is operatively coupled to the main body and has a drop cable jaw and a main cable jaw. The drop cable jaw is movable along the main body between an open position and a closed position. The main cable jaw is movable along the main body between an open position and a closed position. The main cable jaw can be automatically moved from the open position to the closed position. The stem is operatively coupled to the main body and the jaw assembly so that the stem can selectively block the main cable jaw in the open position and release the main cable jaw so that can automatically move to the closed position.

The present disclosure relates to a securing arrangement (102), a suspension assembly (100), and a method. The securing arrangement (102) is for suspending an elongate member (10). The securing arrangement (102) comprises a first securing device (1, 34) for securing an elongate support (6). The securing arrangement (102) further includes a second securing device (30, 44, 70) for securing the elongate member (10). Each of the first and second securing devices (1, 34 and 30, 44, 70) comprises a main part (2, 36, 111), a securing member (15, 117A, 117B, 38, 60) movably mounted on the main part (2, 36, 111), and an urging member (21, 42, 64, 122A, 122B) for urging the securing member (15, 117A, 117B, 38, 60) from a release position to a securing position in which the elongate support (6) or the elongate member (10) are secured by the securing member (15, 117A, 117B, 38, 60).

A transportation system with a non-rail-bound, electrically or diesel-electrically driven vehicle, has a two-pole overhead conductor system with contact wires forming supply and return conductors. The vehicle has a current collector for the supply of electrical energy through sliding contact with the contact wires. A video detector on the vehicle determines a position of the contact wires relative to the vehicle. Marking elements mark the position of the contact wires. The video detector is oriented for taking video images of the marking elements, and an evaluation unit recognizes from a recorded video image whether contact wires are present above the vehicle and, when they are present, determines their position relative to the vehicle. Through the improved recognition of the position of the vehicle relative to the overhead conductor the operational safety of the transportation system is improved.

An overhead line system provides electrical energy for an electrically driven vehicle by use of an overhead line. The overhead line system has a plurality of catenary systems which each have a contact wire connected to a carrying cable by a plurality of connecting devices and which are arranged, on the basis of parallel zones, to form a continuously accessible overhead line. The overhead line system further has an overhead line which is arranged in a curvature section in such a way that the vertical projection of the overhead line has a curved profile in a horizontal plane. The overhead line system also has a curved parallel zone which is arranged in the curvature section in such a way that the vertical projection of the parallel zone into the horizontal plane follows the curved profile of the projection of the at least one overhead line in the curvature section.
