ABSTRACT:
A bucket dump block, used on dragline buckets, has side frames and a rotatable rope-guiding sheave. In the improvement, each side frame has a separate ring-like support section extending toward the other side frame and abutting the support section of such other side frame. The sheave is supported by and rotates about such support sections. The sheave rides on an annular anti-friction member retained on a sleeve into which the support sections are press-fitted. The dump block (which is devoid of provisions for lubrication) has a minimum number of parts and is easy to manufacture and repair.
