Abstract: The present invention relates to a device at rails for exhaust extraction devices, which are adapted for removal of exhausts from vehicles. The rail (2) consists of several rail members (5) which are put together or assembled by means of coupling elements (6). The coupling elements (6) are wedge-shaped and the shape of spaces (9) in rail members (5) for the coupling elements (6) corresponds with the wedge-shape of said coupling elements (6). Mounting means (10) are provided for downward movement (arrow A) relative to the rail members (5) and thereby, for pulling the coupling elements (6) upwards (arrow D) relative to said rail members (5) such that said coupling elements (6) and rail members (5) are secured by wedge to each other.

Abstract: The present invention relates to a device for removal of exhausts from vehicles, which device includes a rail (3) which is mounted in premises in which the vehicle is located when its exhausts shall be removed. The rail (3) may be composed or put together of a plurality of rail members (19) of which each rail member (19) has a length which is similar to or somewhat less than the length of a standard-type pallet (21) so that all the rail members (19) of one rail (3) or several rails (3) can be transported on said pallet (21) in unassembled condition. Each rail member (19) has such coupling spaces in opposite end portions that coupling portions of coupling members (20) can be inserted into coupling spaces of two adjacent rail members (19).
