A cable dropout for a cable tray: The cable tray has side rails. Rungs at spaced intervals along the side rails define the width of the tray with the side rails. The tray side rails have laterally outward extensions at the bottom regions of the side rails for mounting a cable path re-directing dropout to the tray. The dropout has a convexly curved surface for redirecting and supporting a cable from its path on the tray to below the tray. A mounting bar at the entrance region of the dropout from the tray has laterally outward extensions clamped to the bottom region outward extensions at the bottom region of the side rails, so that the mounting bar may be clamped at any location along the side rails.

A support and guiding apparatus for feeder lines having a feed pipe for excavation devices is disclosed. The apparatus has a support branch and a plurality of crosspieces connected with the support branch which includes ring chain having a first and a second series of rings linked to one another in an alternate manner, defining a longitudinal axis (X); a plurality of spacer elements coupled to rings of the first series of rings so that they cannot slide. Each of the spacer elements has a seat that houses a ring of the first series of rings by orienting it in a substantially stable manner on a first lying plane, a second seat and a third seat opposite to each other that partially house the rings of the second series of rings linked to the one housed in the first seat by orienting them on a second lying plane transverse to the first lying plane, each of said spacer elements being arranged to prevent the longitudinal sliding between the rings and to allow the rotation of the rings of the second series of rings only on the second lying plane around a rotation axis perpendicular to the longitudinal axis of the chain and to the second lying plane.

A modular conduit cable management assembly is used with tall vertical structures for holding and managing one or more cables, with the assembly having a plurality of conduit members and a plurality of removable closure members. Each conduit member has at least one retaining arm, a plurality of prongs, an anchor, and a core, with each conduit member defining a slot opening, a plurality of apertures, a holding cavity forming a conduit track, and a receiving chamber. Once assembled, one or more cables can be installed within the conduit track, with at least one of the closure members closing the conduit member slot opening. The cables and each conduit track may be accessed at a later time after removing the closure member.

Cable-routing systems can be provided for a tray configured for movement between an extended position and a stowed position. The cable-routing system can include a biasing mechanism and a pivot. The pivot can receive a bend of a cable about the pivot. The pivot can be coupled with the biasing mechanism. Movement of the tray toward the extended position can pull the cable away from a stored state against a biasing force of the biasing mechanism. The cable can be biased into the stored state by the biasing force of the biasing mechanism when the tray is in or moved toward the stowed position.

A cable ladder formed by two side rails and crosspieces, all formed of extruded polymer material. The side rails have a channel receiving a corresponding end of the crosspieces. The channel has a lower rib and an upper rib. A projection of the lower rib or upper rib has openings along a longitudinal direction of the side rail. The ends of the crosspieces go through the opening of the projection and have a recess in which a corresponding portion of the channel is snap-fitted. The lower rib of the side rails is bent over itself along a bending line, such that a final section of the lower rib experiences downward expansion by elastic bending when the end of the crosspiece is introduced.

A cable guard suitable for the prevention of cable. The cable guard has a housing adapted to receive one or more length of cable, a cover connected to the housing, the cover allowing access to the housing for placing the cable in the housing and a locking mechanism for securing the length of cable inside the housing.
