Compact spreader

摘要

A compact spreader on continuous tracks (10) for use in opencast mining has a discharge boom (70) with a rearward extension designed as a rocker having a counterweight (100). The rocker is suspended centrally in a framework (50) over the turntable (40). Hydraulic cylinders (14) absorb only forces from half of the imposed load. The embodiment according to the invention is suitable for large band widths and discharge projections up to 100 m and eliminates the danger of tipping over.
