<p>An excavating machine 10, representatively a tracked excavator 10 has a boom stick portion 22 on which both an excavating bucket 36 and a breaker assembly 201 are mounted for hydraulically driven pivotal movement between first and second limit positions. The bucket 36 may be operated independently of the breaker assembly 201 for digging operations. Similarly, the breaker assembly 201 may be operated independently of the bucket 36 for refusal material-breaking operations. The same excavating machine 10 may now use the bucket 36 and breaker assembly 201 in a rapid and continuous exchange, to frequently remove small quantities of broken refuse material with the bucket 36, exposing the breaker assembly 201 to fresh refuse material. A deployment system 200 is disclosed having a mounting bracket 202 for closely aligned pivotal support of both the breaker assembly 201 and a single hydraulic cylinder 204. A bi-furcated pivot means, extension stop 276, and latch-lock assembly 282 are also disclosed to increase the control and reliability of the device.</p> |
