BOOM ASSEMBLY WITH YAW ADJUSTMENT

摘要

A boom (17) of a wheeled loader or digger (10) is pivoted about a horizontal axis (18) in forks (29, 30). Yaw adjustment is provided by opposed taper plugs (34, 35) which constitute a spindle of the boom. The taper portions (37) of the plugs are eccentric with respect to the bearing portions (36) and may be rotationally adjusted to correct misalignment of the boom in yaw. A threaded fastener (40) locks the taper plugs to the boom.
