SCRAPER BAIL STOP ASSEMBLY

摘要

A stop assembly (66) for a bail (20) which is particularly useful with the bail (20) of a push-pull scraper (18). The bail (20) is pivotally mounted by a pair of bifurcated brackets (28, 30) affixed to the scraper (18), and is normally raised and lowered by a fluid cylinder (38). When the bail (20) is raised, if not positively stopped from further raising, the fluid cylinder could bottom-out or be otherwise damaged. The stop assembly (66) comprises a fixed pin (68) mounted within the bracket (28) in proximity to a pivotal eye portion (22) of the bail (20), and a first surface (76) on the eye portion (22) which engages with the pin (68) when the bail (20) is in a raised position. Engagement of the first surface (76) with the pin (68) stops the bail (20) from being further raised, and protects the fluid cylinder (28) from damage.
