ABSTRACT:
The vertically swingable boom of the apparatus is articulated to present a joint that is spaced outwardly from the horizontal swinging axis of the lift cylinder for the boom. A rigid link transversely and pivotally interconnects the lift cylinder and the inner section of the boom to control articulation of the latter about the joint during swinging of the boom. Consequently, the moment between the line of action of the lift cylinder and the boom remains favorably high at all locations on the path of swinging travel of the boom and the lift cylinder can swing through an arc approaching 180.degree. during its operation of the boom.
