ABSTRACT:
The load carrying upper reach of a belt conveyor particularly useful for transporting large pieces of rock and other heavy bulk material dispenses with the usual idle troughing rollers and is supported by an endless succession of spaced transverse flexible cross members or hammocks each of which has a trolley at each end riding on endless rails extending along each side of the belt and around the rollers at the head and discharge ends of the belt conveyor. Along the return strand of the conveyor belt the hammocks are above the belt but rest on it. The side-to-side distance between rails is less than the width of the conveyor belt so that the weighed belt cradles itself in the hammocks. However, at the head end of the conveyor there is a decending traveling belt ramp and at the discharge end an upwardly sloping belt ramp to flatten the hammocks and the belt for passage around the head and tail pulleys respectively. In these areas, the rails spread apart to take up the slack in the hammocks. An impact support is positioned under the belt and the hammocks at the place where the material to be transported is charged onto the belt to cushion the fall of heavy masses onto the belt.
