发明名称 DUMP BLOCK WITH IMPROVED ASSEMBLY FEATURES
摘要 A dump block with a self-adjusting bearing includes two side sections, a sheave with a peripheral groove and a central bore, a bearing assembly, and a sheave pin. The sheave pin has a first end with a shoulder, a second end with a threaded portion, and a bearing support section of a predetermined length extending between the first and second ends. The sheave pin is positioned within the bearing assembly and adjusted by urging the sheave pin to translate in the direction of the second end. A fastener is secured to the threaded section at a location between the two side sections.
