<p>A telescopic belt conveyor (2) comprising a basic conveyor section (A), a number of intermediate telescopic conveyor sections (B, C), and an outermost telescopic conveyor section (D), said conveyor sections (A-D) are mutually connected by means of a number of drive chains (20) which are lead over sprocket wheels (10, 12, 14, 16, 18) for execution telescoping movement in and out of said telescopic conveyor sections (B, C, D) by means of a common drive unit, and an endless conveyor belt (4) constitution an active conveying track of said conveyor sections (A-D), said conveyor sections are drive-connected with a common drive system, where said electric control system comprises an integrated security system, and that there at outermost ends of said conveyor sections are provided anti-squeeze means (42, 48) with an electric switch (46, 54) being a part of said security system. In a simple manner and by means of simple provisions it is hereby possible to overcome said disadvantageous including said personal damages mainly concerning hands and fingers. Furthermore the telescopic belt conveyor may furthermore comprise electric brake means, which are adapted to engage between the respective conveyor sections, and which being controlled in a such manner, that said brake means by power failure, broken chains and by activating security switches automatic brakes any telescopic movement of the respective conveyor sections. <IMAGE> <IMAGE></p> |
