ABSTRACT:
Conveyor for light goods, and connection piece for beam sides of a conveyor. The conveyor has a first supporting guide arrangement (10) for controlling the conveyor chain (11) in an operational direction, a second guide arrangement (17) for controlling the conveyor chain in the return direction, and a deflector wheel arrangement (20) (FIG.3) at both ends of the first and second guide arrangements. The first guide arrangement (10) is made up of beam sides (10a, 10b) which between them form a space which narrows in the direction towards the second guide arrangement (17). A two-part connection piece (12) which has a wedge-shaped element (12a) fixes the position of the beam sides by means of a wedging effect between the wedge-shaped-element of the connection piece and a complementary recess in the second element (12b) of the connection piece. A tensioning bolt (13) inserted at right angles between the plane of the conveyor chain of the guide arrangements generates said wedging effect. Between the beam sides (10a, 10b) there is a drainage gap (15), and the underside of the conveyor chain is protected against contamination by the base part of the second guide arrangement (17) shaped as a U-beam.
