A mooring buoy for a vessel comprises a floating body arranged to project out of the water. At least one buoy anchoring line is connected between the floating body and sea floor. At least one vessel mooring line is connectable between the mooring buoy and the vessel. At least one moveable electric cable is connected to a power supply and the moveable electric cable has a free end connectable to a switchboard of the vessel when the vessel is tethered to the at least one vessel mooring line. The free end of the at least one moveable electric cable is moveable between a retracted position and a connected position and the tension of the at least one vessel mooring line is greater than the tension in the at least one moveable electric cable when the free end of the at least one moveable electric cable is in the connected position.

A dynamic line guiding system for high speeds and/or long displacement paths, with an energy chain arranged as lying on the side, which chain, in the configuration of a first strand, a second strand, as well as a deflection curve, is displaceable back and forth. The energy chain is guided in a guide trough with two laterally-opposite side walls and a trough floor therebetween, wherein each strand is respectively displaceable with a lateral surface on a respective bearing surface on the trough floor, and is held, relative to the outside, by means of one of the two side walls. It is provided that the trough floor comprises at least one bearing surface with a step or a ramp, which counteracts a deviation of the first strand out of its intended target location on the respective bearing surface.

At least one first section of a cable guide for receiving energy or communication cables in a receiving area can be arranged in the form of a first and second strand (3, 4), which are connected together by a deflecting region (2) extending about a deflecting arc, wherein the cable guide can be moved about the deflecting arc of the deflecting region (2). The aim of the invention is to allow a movement of the cable guide about the deflecting arc in the most frictionless manner possible while keeping the deflecting region stable. This is achieved in that a stabilization element (5) is provided which is substantially adapted to the deflecting arc and is arranged in a deflecting region (2) guide area that extends along the first section of the cable guide and passes through said section at least in one region and which supports the deflecting region (2) in the guide area in a floating manner when the cable guide is being moved about the deflecting arc without emerging from the guide area.

A machine tool including a base, a slider that is supported to be linearly movable in a direction with respect to the base, a ball screw configured to cause the slider to linearly move with respect to the base, and a chain-like carrier used for wiring a movable wire body between the base and the slider. The carrier is disposed between the base and the slider and curved in a U-shape around an axis extending in a direction in which the base and the slider are apart from each other, one end of the carrier is fixed to the slider and an other end of the carrier is fixed to the base, and a curved portion of the carrier, which is curved in the U-shape, is disposed at a position where the curved portion crosses an extension line of an axis of the ball screw.

A cable guiding structure (200) for a tower (108) of a wind turbine (10) is described. The tower has a height in substantially vertical direction (110) and a width in substantially horizontal direction (112). The cable guiding structure (200) is adapted for guiding a cable (160) within the tower of the wind turbine. The cable guiding structure includes a horizontal movement element (300) at least partially movable in the width direction (112) of the tower (108). The horizontal movement element (300) includes a receiving part (301) for receiving the at least one cable (160) of the wind turbine and wherein the horizontal movement element allows a movement of the at least one cable (160) in the width direction (112) of the tower (100). Further, a method for mounting a cable guiding structure is described.

Energy chains having flexible joint connectors, and lateral tabs and a joint connector therefor. The lateral tabs are symmetrical by stop surfaces thereof, wherein each lateral tab comprises two protrusions having stop surfaces and two pockets having counterpart stop surfaces. According to one aspect, the protrusions and the pockets are provided symmetrically on the lateral tab. According to one aspect, the joint connector for lateral tabs has a plate-like body having a resiliently flexible joint region, two material regions opposingly arched outward having a cavity therebetween, and two opposite fastening regions on the end. According to one aspect, the energy chain is designed such that, continuously over a chain portion comprising at least more than three adjacent chain links, which comprises the at least two tab strands, the tab strands are structured overall continuously from tabs which are identical to each other.

A system for monitoring the state of a cable, which is guided in an energy chain between a base and a movable driver element. The movable energy chain forms a movable run at a driver element, a resting run at a base and, between the two runs, a deflecting bend. A monitoring device having at least one indicating element at the energy chain evaluates an indicating-element signal and monitors whether an error state occurs. The indicating element has two electrical indicating conductors guided by the energy chain, which indicating conductors extend along the movable run, and the monitoring device comprises a measuring circuit for resistance measurement or conductance measurement. One end point of each indicating conductor is connected to the measuring circuit and the other end points of the indicating conductors are short circuited such that the indicating conductors form a measurement loop.
