Abstract: A cable tray system has two or more cable tray segments, the cable tray segments each having a cable tray underside and two cable tray side cheeks which laterally delimit the cable tray underside and form a substantially U-shaped cross section. A connecting section is provided at one end of one cable tray segment and one end of another cable tray segment can be connected in or on this connecting section with complementary mechanical connecting elements by means of a clamping or latching connection. When two corresponding ends of the cable tray segments are plugged together in the longitudinal direction of the cable tray segments and also in the vertical direction of the cable tray segments, the ends are resiliently bent towards each other until a desired connection position is reached and form a snap-in connection that locks in the longitudinal and vertical directions.

Abstract: The present invention relates to a cable duct lid that can be walked on with a cover member having an upper surface and a lower surface, and two lateral parts protruding from the cover member, said lateral parts each forming a lateral edge of the cable duct lid. The upper surface of the cover member includes a structured central region that is formed by way of embossing or impressing from the lower surface and that provides a slip-resistant surface. The upper surface of the cover member has a non-structured periphery on each of both sides of the structured central region towards the respective lateral edge, said non-structured periphery having a width of 5 mm or more. The invention further relates to a cable duct with a cable duct tray, a cable duct lid that can be walked on as described above, and at least one lid retaining spring and/or at least one quarter-turn lock for mounting the cable duct lid onto the cable duct tray.
