Abstract: A belt conveyor for a road-finishing machine or a charger. The belt conveyor includes a conveyor belt in which a displaceably mounted support element abuts the conveyor belt, and a first and a second piston cylinder unit operate to displace the support element. The first and the second hydraulic piston cylinder units can be pressurised independently of each other in order to move the support element into a desired inclined position. If the conveyor belt of the belt conveyor runs laterally away from the support element, the out-of-true running of the conveyor belt can be counteracted by an inclined position of the support element which moves the conveyor belt back into its original position.

Abstract: The invention relates to a conveyor belt mounting for a charger that is used in road building, in order to supply a road-finishing machine with paving material. Using the slewing belt mounting, it is possible to achieve different discharge heights for the paving material. The slewing belt mounting comprises a cantilever arm, which is movably mounted on the frame of the charger, a pivot arm, which is pivotally connected to the cantilever arm, and a conveyor belt, which is connected to the pivot arm. The slewing belt mounting is characterized in that it comprises at least one lifting element, such as a hydraulic cylinder, cable winch, toothed rack, gear mechanism or the like, which is fastened by a first end to the frame and by a second end to the cantilever arm, wherein the cantilever arm is vertically adjustable by means of the lifting element.

Abstract: The invention relates to a conveyor device (20), wherein the conveyor device (20) comprises a frame, guide elements (10) supported by the frame, and a conveyor belt (7) guided around the guide elements (10). The invention is characterized in that the frame is assembled from a plurality of frame modules (21, 22, 23), wherein at least one of the frame modules (21, 22, 23) is exchangeable in order to alter the length of the conveyor device (20).

Abstract: A belt conveyor device for construction machines such as road finishing machines with a continuous conveyor belt that is carried in a conveying plane in a conveying duct by drive and tail pulleys situated inside the conveyor belt, and optionally by support rolls, which are installed in a frame structure defining the conveying duct. The drive and tail pulleys can be moved out of the conveyor belt for replacement with an adjustment arrangement that can be installed or integrated into the frame structure.

Abstract: In a belt conveyor device with a continuous conveyor belt which is replaceably carried in a conveying duct by inner drive and tail pulleys which are installed in a frame structure defining the conveying duct, at least the drive and the tail pulley can be moved to a replacement position by means of adjusting means integrated in the frame structure, in which position the respective pulley or at least one pulley end is placed outside the conveying duct for conveyor belt replacement, or parts of the frame structure that interfere with the mounting of the conveyor belt can be removed by folding them away, dismounting them, or the like.
