Abstract
Abstract This invention relates to a suspension apparatus for control devices which can be assembled from a connection flange or connection rotary joint, support beam sections, elbow joints, or intermediate joints which can be connected with a wall or the body of a machine, and a coupling unit which can be connected to the control device. The support beam section comprises an essentially U-shaped base profile section and a cover profile section closing the same. The base profile section is divided, by means of a separating bar parallel to its crossbar, into a support part constructed as a closed hollow profile and an open U-shaped mounting part opposed to the bar. The connection bars, which proceed in a longitudinal direction in the support part and in the mounting part, are integrally formed with screw mountings. The intermediate joint comprises two joint parts which can be bolted directly to the front sides of the base profile section acting on one another, without impairing the positioning of the connection lines and the guiding of the same with the intermediate joint.
