Abstract: The present invention relates to a carrier unit, comprising at least one carrier frame (1) having mountably arranged devices (3 or 29) provided with hook portions (4) for cooperation with the carrier frame and mounting portions (6) for cooperation with at least one plate element (18).In order to increase the carrying capacity without increasing the number and/or size of the members forming part of the carrier unit, as has been previously necessary, the invention is characterized in that the plate element (18) protrudes in between the mounting portions (6) of at least a pair of connecting devices (3 or 29) mounted on the carrier frame (1) and is secured to said mounting portions by means of at least one joint (22) extending through the mounting portions and the intermediate plate element.
