Abstract: A skid for supporting at least one object which is conveyable in a conveying direction inside a conveyor installation comprises at least two support runners disposed parallel to one another. Running means different from the support runners are fastened to the skid. In addition, a transfer station for transferring an above-mentioned skid from conveying means to a guide structure is specified. Also specified are a self-propelling drive unit with a chassis and a coupling device by means of which a skid can be coupled detachably to the chassis, a drive system for driving a skid and a conveyor installation, in which a drive unit is provided inside a conveying area.

Abstract: A system for treating surfaces of objects, in particular for painting objects, in particular vehicle body parts, comprising a treatment booth, which defines a treatment space. The objects are conveyed into and back out of the treatment space by means of a conveying device. The conveying device comprises a conveying element, by means of which a first surface having a first retaining device for at least one object and at least one second surface having a second retaining device for at least one object are provided. The first and the second surface are arranged in such a way that the first or the second surface bounds the treatment space at least in some areas depending on the position of the conveying element.

Abstract: An overhead conveyor system for transporting articles, especially for transporting vehicle bodies, in a treatment line comprises at least one transport carriage which has a fastening device to which at least one article can be fastened. The transport carriage can be displaced along the track by at least one drive means. The transport carriage is designed in such a manner that the fastening device can be transported at least along one section of the track, in a laterally offset manner with respect to the track. The invention further relates to a dip coating line comprising at least one dip-coating tank which can be filled with a treatment liquid, into which tank articles to be treated, especially vehicle bodies, are dipped. A conveying system can displace the articles to be treated towards the dip-coating tanker, into the inner edge of the dip-coating tanker, out of the dip-coating tank and away therefrom.

Abstract: The invention relates to an immersion treatment system, particularly an electrophoretic immersion coating system, comprising at least one immersion basin in a known manner that can be filled with a treatment fluid. A transport system guides the objects to be coated to the immersion basin, into the interior of the immersion basin, out of the immersion basin, and away therefrom. It comprises at least one transport car whereon a vertically displaceable carriage is disposed. A component defining a rotary axis is supported on the same, supporting a mounting device for the object to be treated. A motion sequence for the object can be achieved in said manner, comprising a superposition of a horizontal linear motion, a vertical linear motion, and a rotary motion about the rotary axis.

Abstract: An overhead conveyor system for transporting articles, especially for transporting vehicle bodies, in a surface treatment line comprises at least one transport carriage which has a fastening device to which at least one article can be fastened. The transport carriage can be displaced along a track carrying it by at least one drive means. The fastening device is received so that it can be rotated about a vertical axis of rotation. The invention further relates to a dip coating line comprising at least one dip-coating tank which can be filled with a treatment liquid, into which tank articles to be treated can be dipped. The dip coating line comprises a conveying system which displaces the articles to be treated towards the dip-coating tank, into the interior of the dip-coating tank, out of the dip-coating tank and away therefrom.

Abstract: A lifting station for vertically moving an object, in particular a vehicle body, in a surface treatment installation includes a fixed support structure and a vertically movable lifting cradle which is supported on the support structure and on which at least one conveying device is arranged. Energy for actuating the conveying device can be stored in an energy accumulator arranged on the lifting cradle. In this way, a trailing cable which supplies the conveying device with energy in different lifting positions is not required.

Abstract: A lifting station for vertically moving an object, in particular a vehicle body, in a surface treatment installation includes a fixed support structure and a vertically movable lifting cradle which is supported on the support structure and on which at least one conveying device is arranged. According to the invention an energy transfer device, with which energy can be transferred to the conveying device only in at least one selected lifting position of the lifting cradle is provided. As a result, a trailing cable can be dispensed with.

Abstract: A surface treatment installation, in particular for the treatment of vehicle bodies, comprises a lifting station (24, 25) for vertically displacing an object (12). The lifting station has a stationary supporting structure (34) with two vertical guiding uprights (26, 28), and a lifting slide (40) which is supported on the supporting structure (34) via guiding rollers (64, 66, 68, 70) bearing against the guiding uprights (26, 28) at least at two points. The lifting station further has a loading arm (54) which is fastened to the lifting slide (40) and serves for receiving the object (12). According to the invention, it is provided that at least one guiding roller (64, 66, 68, 70; 64a; 64b; 64c; 64d; 66d) has a non-cylindrical shape in order to obtain a guiding direction different from a radial direction. This enables a vertical guidance of the lifting slide (40) with fewer guiding rollers.
