AN ARRANGEMENT OF THE CROWD CYLINDER CRANK ARM AND LINKAGE MECHANISM FOR GIVING FREEDOM OF MOVEMENT FOR LOADING AND TILTING IMPLEMENTS AND BUCKETS.

摘要

A crowd cylinder axle or crank arm (9.006) is offset from its rotational axis and includes a crowd cylinder pivot support 9.044 which is unobstructed in the direction of rotational operation of the cylinder about pivot point 9.010. The axle is attached to a pair of booms (1.002,1.004), and a cross-bar (1.008) joins the booms. The cross-bar (1.008) is curved to permit greater freedom of rotational movement for the crowd cylinder. As a result of the freedom of rotational movement, the bucket can be joined to each boom by a single pivot, avoiding the need for additional linkages between the boom and bucket.
