Abstract: In order to provide a walk-on platform arrangement, comprising at least one first sub-platform, which is movable from a rest position in a direction of extension into a working position, and a second sub-platform, which in the working position is disposed behind the first sub-platform, wherein a rear boundary edge of the first sub-platform and a front boundary edge of the second sub-platform in the rest position are spaced vertically apart from one another, with which platform arrangement the risk of accident for an operative walking on the platform arrangement in the working position is reduced, it is proposed that the platform arrangement comprises a guide system, by means of which the relative motion between the first sub-platform and the second sub-platform as the first sub-platform moves into the working position is guided in such a way that the vertical distance between the rear boundary edge of the first sub-platform and the front boundary edge of the second sub-platform in the working position is smal

Abstract: A process for conveying vehicle bodies through a treatment tank for the surface treatment of the vehicle bodies, where the liquid of the treatment tank offers only a slight immersion resistance to the vehicle bodies during immersion and the flow velocities of the liquid relative to the submerging and emerging vehicle bodies are kept low. Prior to their introduction into the treatment tank the vehicle bodies are transferred from a standard position, in which window openings of each vehicle body are arranged above the floor pan of the vehicle body, into a headfirst position, in which the window openings of each vehicle body are arranged beneath the floor pan of the vehicle body. The vehicle bodies are subsequently introduced into the treatment tank in the headfirst position, conveyed through the treatment tank and brought out of the treatment tank again in the headfirst position.

Abstract: In order to produce a tank for accommodating a fluid used for the surface treatment of work pieces, especially vehicle bodies, wherein the fluid accommodated in the tank can be kept free of dirt particles with little outlay, it is proposed that the tank comprise dirt collecting compartments which are arranged in the base region of the tank.

Abstract: To improve a manufacturing installation comprising a plurality of functional units carrying out at least one function and cooperating in the manufacturing installation, each of the functional units comprising at least one actor and at least one sensor for function control and/or function monitoring, such that it is less susceptible, it is proposed that the functional unit comprise at least one intelligent control unit which operates independently of a central computer and in accordance with a function control program of its own stored in a program memory, with the control unit controlling the at least one actor and/or evaluating signals of the at least one sensor in accordance with the function control program.
