1. Belt-type spreader for an installation for spreading continuously conveyable material to dump the chassis of which rests on three supporting points and which has a stacker boom wherein to move the spreader there is a transport vehicle and said transport vehicle is not permanently secured to the chassis of the spreader characterized in that the chassis of the spreader is formed by a long support cross beam (1) and a short support cross beam (2) connected to each other by two spaced longitudinal support ties (3) wherein between both cross support beams (1, 2) two angle braces (4) are arranged thus forming with said cross support beams trapezium, the chassis supporting points take the form of a pontoon (5), standing on the base wherein two pontoons (5) are arranged under each long cross support beam (1) and one pontoon under short cross support beam (2). 2. Belt-type spreader according to Claim 1 characterized in that a supplying belt conveyer (10) is arranged between two longitudinal support ties (3) to move conveyable material to belt conveyer (11) of stacker boom (7). 3. Belt-type spreader according to Claim 2 characterized in that belt conveyer (11) of stacker boom (7) has less width and works with higher speed than supplying belt conveyer (10) between the chassis longitudinal support ties. 4. Belt-type spreader according to Claims 1, 2 or 3 characterized in that stack boom (7) sits on the chassis rigidly. 5. Belt-type spreader according to any of preceding Claims characterized in that stack boom (7) moves upward and downward. 6. Belt-type spreader according to Claim 5 characterized in that hydraulic cylinder (8) is used to raise and lower stack boom (7). |
