Abstract:
A ripper in which the ground engaging tip can be advanced in its holder to accommodate for wear of the ripper tip. The tip may be advanced manually or hydraulically depending on the mechanism used and is held in place by friction and/or a pinning means.
Abstract:
A machine is supported by four ground-engaging cushioned tracks. Each cushioned track comprises an annular resilient spacer having an endless track assembly mounted therearound. The track assembly comprises a plurality of shoes having flat inner surface portions surrounding and compressing the outer periphery of the spacer to normally define a substantially continuous, polygonal-shaped surface contact therebetween. The shoes extend laterally across the spacer and are connected together by laterally spaced link assemblies each positioned at a respective side of the spacer to form a unitized cushioned track.
Abstract:
The earth handling components of a scraper of the kind having a hoeing apron mounted on powered articulated linkage are actuated by means of a single operator''s control lever which may be pivoted forwardly, backwardly or to either side and which may be lifted or depressed or rotated in either of two directions, wherein each motion operates a different one of a plurality of electrical switches which control solenoid valves operating fluid jacks coupled to the several scraper components. Ten different scraper component movements may be initiated by appropriate positioning of the single lever, either individually or in certain selected combinations.
Abstract:
In a scraper having an apron which may be advanced and retracted relative to the bowl in addition to being raised and lowered to provide a hoeing action and having a bucket type of ejector which may be advanced and retracted in the bowl, highly efficient loading is realized by advancing the ejector to receive the material which is loaded by the apron in the initial portion of the cycle and then retracting the ejector to move such material to the rear of the bowl thereby facilitating subsequent loading at the front of the bowl. During ejection, the apron may be scraped down along the forward surface of the ejector to dislodge material.
