A high-speed stroke-type moving device for an elongate flexible body having at least one supply line. The device has a guideway for guided displacement of the body, having a spiral portion, in which at least part of the body is compactly accommodatable in a plurality of spaced tracks which are not in mutual contact and extend substantially spirally inwards. The invention provides that the body has a line guideway for the at least one supply line. According to the invention, the line guideway here has a first sub-portion which is guided in the spiral portion and an unguided second sub-portion having a first end which is connected at the end to the first sub-portion and a second end which is connected at the end to a rotary feedthrough for the at least one supply line. A corresponding device having an energy chain is furthermore disclosed.

A transverse bar for a chain link of an energy guiding chain for guiding lines. The transverse bar has an elongate main body comprising a first plastic and at both longitudinal ends a connecting region for connection to the side plates. The main body of the transverse bar has two long narrow sides which each have a holding device for separating bars. Provided on the inside of the main body that faces towards the lines is a line-protecting layer for handling the lines gently and comprising a second plastic which is different from the plastic of the main body and is selected to reduce abrasion upon relative movement between a line and the transverse bar. In that case the line-protecting layer extends from one narrow side to the other and at least predominantly covers over the inside of the main body but leaves uncovered the respective holding device at the one narrow side and at the other narrow side.

A tension relief for a cable carrier. A multi-part holding frame comprising bars which are connected by side parts holds block-like spacers, between which a plurality of lines, such as cables, hoses or the like, are laid. In order to exert a clamping force by the holding frame on the spacers for the purpose of strain relief, a quickly closable device is provided. A quick release clamp can be provided, which in the closed position clamps the side parts and/or the bars to one another. According to the invention, the two side parts are mounted pivotably on the lower strip and are fastened releasably to the first bar, for example by screws or the quick release clamp. Each side part can thus be pivoted from the closed position into an open position and vice versa in order to release and clamp the lines respectively.

Actuation systems and methods for actuating a telescopic structure are provided. The actuation system can include a chain cartridge including a drive chain engageably coupled to a drive mechanism actuated by an actuator coupled to a power supply. The drive chain can include a plurality of inter-connected links conveying at least one cable within an interior space of each inter-connected link. The system can also include a telescopic structure including a plurality of segments configured to extend and retract telescopically and conveying the drive chain therein. The drive chain can couple to a distal segment of the plurality of segments. The drive mechanism can impart a linear translation force on the plurality of inter-connected links to cause the distal segment to extend or retract from the telescopic structure. Methods of actuating the actuation system described herein are also provided.

A transport system includes a transport device to transport an article, a cable unit, one end of which is connected to the transport device, the other end of which is fixed to ground side, the cable unit configured to move in accordance with movement of the transport device, and a placement section capable of placing the cable unit. The placement section has a base, and a first damping member provided on the base and having damping properties higher than that of the base. The first damping member does not support the cable unit thereon.
