A conveying system comprises a plurality of conveyor units (A, B) each having a frame (1) supporting a roller (4, 5) at each end over which a conveyor belt (6) passes in a continuous loop and one of which is driven by an electric motor (25), characterised in that each of said conveyor units (A) is portable so that it can be readily located in relation to the other conveyor unit or units (B) to form a conveyor feed path, the electric motors (25) of successive conveyor units (A, B) being interconnected by electrical cables (D, E) via quick-release electrical connectors (17, 18) so that they are powered and controlled in a common power circuit (21, 23, 24). Each electric motor (25) is reversible and the sense in which it rotates is determined by the manner in which it is interconnected in the common power circuit (21, 23, 24) by the electrical cables (D, E). The frame (1) consists of an elongate box-section with upright box-section side walls (8, 9), and upper and lower bed plates (3), and is filled with rigid structural foam (13). |
