Abstract: Feeding appliances have an elongate continuous conveyor (14) which serves as a distributing conveyor. The distributing conveyor is required only in certain usage situations. Said distributing conveyor must thus be detached when not in use. Detachment is also required for the transportation of the feeding appliance by road. In the case of known feeding appliances, the attachment and detachment of the longitudinal conveyor (17), which serves as distributing conveyor, is cumbersome. The invention provides for the longitudinal conveyor (17) to be connected to a running gear (12) of the feeding appliance by being hooked on or hooked in. This can be realized by virtue of the longitudinal conveyor (17) being simply lowered or raised by a suitable lifting means, for example a crane. Time-consuming and difficult alignment work is thus eliminated.

Abstract: An eccentric shaft for a compacting machine is rotatable about a rotational axis and includes a fixed and movable eccentric mass where the movable eccentric mass cooperates with the fixed eccentric mass in one of the directions of rotation of the eccentric shaft to partly balance the fixed eccentric mass in the other rotation direction of the eccentric shaft. At least one section of the fixed eccentric mass shows a maximal radial extension (UB) in relation to the rotational axis, limited by an arc-shaped curve, which extends to a circle shape, with the diameter (D) showing a distance (A), between the point (P) on the circle-shaped curve that is located closest to the point of intersection of the rotational axis and the section plane, and the point of intersection, from 0 up to 0.1(D).

Abstract: In the production of road surfaces of asphalt and concrete (33), it has been necessary hitherto to use different road pavers, which requires additional complexity, in particular when a wearing course (32) of concrete (33) is to be applied to a base (31) of asphalt. The invention provides to produce road surfaces of concrete (33) with a road paver intended for the processing of asphalt in that suspended vibrating bodies (23) are used which are inserted at least partially into the concrete (33) to be compacted. As a result, a road surface of concrete (33) can be produced with a road paver intended for the laying of road surfaces of asphalt. A laying screed (17) of the road paver is preferably guided rigidly, that is to say non-height-adjustably.

Abstract: The invention relates to a method and an apparatus for homogenizing bulk material, wherein the bulk material is supplied from above into a container which is restricted sidewards and downwards and is fed out by means of a feeding out conveyor located in the lower portion of the container. The characteristic features of the invention are that the bulk material is fed in from above in one end of the container (20), wherein the bulk material is caused to slide down towards the opposite end of the container such that a bed of bulk material is formed having a sloping profile in the container, and wherein, due to the sliding, heavier and/or coarser fractions of the bulk material slides more than lighter fractions, and that during each time unit a volume of bulk material is fed out from the bottom portion of the container from each section (.DELTA.

Abstract: The invention relates to a road roller primarily for compacting road surfacing materials such as asphalt. The road roller provides an ergonomic workplace for the operator in the cabin of the road roller and offers an unobstructed view of the rollers (4 and 12) and especially of the lateral edges (4a and 12a), respectively, thereof. This is of major importance when positioning the road roller on the surface to be compacted. This is achieved with an asymmetrical arrangement of the cabin; that is, one side of the cabin extends beyond the lateral edges (4a and 12a), and the operator's seat 6, with the steering wheel 7 and controls 8, is pivotally and laterally displaceable within the cabin.
