RELONG wheel head is a highly efficient tool for dredging a wide range of materials. Excellent cutting properties, a constant dredging output in both directions of swing, and the almost complete absence of blockage ensure high production. Optimum mixture density, low spillage and low sensitivity to debris such as rocks and tree stumps significantly contribute to efficiency. The dredging wheel may be seen as the most thoroughly tested and developed tool of its type, and the best for meeting the growing demands of the dredging and alluvial mining industries.
