Abstract: A boarding and/or access aid for vehicles with passenger carrying service contains a frame with two parallel side parts (4) connected by an end profile (5), contains a step plate (2) supported in the side parts (4) in such a manner that it can be retracted and extended, and contains drive means comprising a drive motor (10) for the step plate (2). According to the invention the drive means contains two drive elements (19) designed as a chain or belt and associated one of the two side parts (4), which drive elements are arranged between guide tracks (9) and outer walls (4c) of the associated side parts (4), have a driving connection to the step plate (2) and are guided over a deflection roller (18) and a drive roller (17) connected to the drive motor (10).

Abstract: A boarding and/or access aid for vehicles with passenger carrying service has a frame with two parallel side parts and an end profile connecting the latter, a step plate supported in the side parts so that it can be extended and retracted, and a drive for the step plate, supported on the frame, arranged between the two side parts and comprising a drive motor. The drive has a drive element, a chain or a belt, guided over at least one deflection roller, and a drive roller arranged in the area of the end profile, coupled to the drive motor, having a larger diameter than the deflection roller, and arranged in a inner space surrounded by the frame. A pressure roller acting from the outside on an upper belt side of the drive element is associated with the drive roller so that the upper belt strand is arranged between it and the deflection roller parallel to the movement path but underneath the latter.

Abstract: A boarding and/or entry aid for vehicles for carrying passengers is described, having a rectangular frame (3) and a step plate (2) supported movably in it. The frame (3) has two parallel lateral parts (4), which are joined together at rear ends by an end profile (5) and in a region spaced apart from it by at least one bracing strut. The lateral parts (4), end profile (5) and bracing strut are provided according to the invention with positioning means (14, 15) that engage one another in form-locking fashion.

Abstract: The invention relates to a process for producing thin hot-rolled steel strip with a final thickness of <1 mm from strip-cast feedstock in sequential steps, including surface descaling a cast feedstock, rolling the feedstock in six passes in a tandem Steckel roll line, coiling and uncoiling the feedstock after its first and second passage through the tandem Steckel roll line in furnaces arranged on the entry and exit sides of the tandem Steckel roll line. After a third passage through the Steckel roll line, the feedstock is coiled up in an exit-side coiling device having two furnaces one atop the other, which serves as a storage device for the roughed strip. Simultaneously with the coiling of the first strip, a second strip is uncoiled from the storage device. The cropped front end of the second strip is welded to the cropped rear end of the already uncoiled roughed strip.

Abstract: A furnace installation as an intermediate storage between a mandrel-free coiling mechanism for strip-shaped cast billet, which is arranged downstream of a thin slab casting installation, and an uncoiling mechanism communicating with a downstream rolling mill, and a system for transporting the coiled bundles through the furnace installation. The furnace installation includes an integral coiling mechanism on the charging side. At least one transporting device for transporting the bundles is provided outside and below the furnace installation and is movable along the furnace installation. The transporting device penetrates into the furnace installation by lifting/lowering supports for the bundle to be transported. The uncoiling mechanism is likewise integrated in the furnace installation at a distance from the coiling mechanism which allows a plurality of bundles arranged adjacent to one another to be picked up. The uncoiling mechanism communicates with the coiling mechanism via the transporting device.

Abstract: A process for producing hot-rolled steel strip from strip-form cast feedstock in consecutive work steps, in which the solidified feedstock is roughed down in a particular sequence by reversing roll passes. The feedstock is then coiled up for temporary storage in a furnace atmosphere, and finally supplied to a finishing train to be rolled down to the finished band thickness. The machine for carrying out this process includes a temperature-controlled intermediate storage furnace provided between a reversing Steckel mill and the multi-stand finishing train.
