Abstract

866,619. Shovel excavators. BLAW KNOX Ltd. Jan. 1, 1960 [Jan. 1, 1959], No. 69/59. Class 68(1). The articulated boom of a shovel excavator is formed by two parallelogram linkage systems 11, 15, 29, 27 and 18, 27, 32, 12. On the component structure 12 of the outer linkage system is pivotally mounted a scoop 13 and on the underside of the structure 12 is formed a framework 34 that engages the ground to steady the boom whilst the scoop is being pivoted by a jack 26 during a digging operation.
