A cover belt conveyor with a basic belt guided by three support rollers (,) arranged in a trough-shaped pattern. To guarantee the ability of such a cover belt conveyor to function at different amounts of material to be conveyed, four pressure rollers (,) are arranged over the entire width of the cover belt (,) in the case of a basic belt (,) with a troughed support roller station comprising three support rollers (,) such that the two middle pressure rollers (,) always act on the area opposite the middle roller (,) and the two outer pressure rollers (,) of the cover belt (,) act on the area opposite the two oblique support rollers (,). The pressure rollers (,) are arranged individually pivotably on the frame of the conveyor and they can thus automatically adapt themselves to the particular volume of material to be conveyed between zero and a maximum and apply the necessary pressure on the cover belt (,) in the process. Two inner and two outer pressure rollers (,and,) are always arranged alternatingly in the direction of conveying.

Cover belt conveyor for conveying bulk material

A level boom is provided for a piece of strip mining equipment traveling on caterpillar-type chassis, which piece of equipment is temporarily moved on oblique roadways during operation. The position of the boom in relation to the skeletal structure is corrected with simple means. A piece of strip mining equipment with a boom, which can be lifted and lowered and at the free end of which, e.g., a bucket wheel for picking up a load is arranged, is connected to the substructure of the piece of equipment in a pivot axis. The lifting movement is brought about by a lifting cylinder. A tilting support, which carries the boom, is arranged in the pivot axis for lifting and lowering the boom. A bolt connection is provided on one side in the pivot axis for leveling between the tilting support and the boom, and the actuating element for leveling as well as a step bearing for absorbing lateral forces which the actuating element is unable to absorb, are located on the other side. Since the actuating element for lifting and lowering the boom is arranged in the pivot axis for leveling, no additional support elements are needed.
