  "claims": [
    "1. A method of deploying a mobile material processing plant comprising the steps of: providing a first frame support member having a first frame longitudinal axis; providing a material processing plant which creates vibration during operation; providing a first rubber isolation mount between the first frame support member and the material processing plant; providing a first front telescoping jack with a first front telescoping jack top portion and a first front telescoping jack bottom portion, with first front telescoping jack longitudinal axis which is not co-planar with said first frame support member, said first front telescoping jack is sized, located and configured to provide some support of the material processing plant; wherein said material processing plant is a cone crusher; providing a second front telescoping jack with a second front telescoping jack longitudinal axis, where said first front telescoping jack longitudinal axis and said second front telescoping jack longitudinal axis are upwardly and inwardly inclined; providing a first rear telescoping jack, with a first rear telescoping jack longitudinal axis and a second rear telescoping jack with a second rear telescoping jack longitudinal axis; and wherein each of said jacks is free of any structure configured to limit vibration induced internal jack relative motions.",
    "2. The method of claim 1 wherein each of said jacks is not vertical with respect to the first frame support member.",
    "3. The method of claim 1 wherein each of said jacks is canted.",
    "4. The method of claim 1 wherein each of said jacks is oriented so that a top portion of each jack is closer to a top portion of any other of said jacks than are their respective bottom portions.",
    "5. The method of claim 1 wherein bottom portions of each jack are splayed apart.",
    "6. The method of claim 2 wherein each of said jacks is canted, each of said jacks is oriented so that a top portion of each jack is closer to a top portion of any other of said jacks than are their respective bottom portions, wherein bottom portions of each jack are splayed apart, and wherein each of said jacks is tilted toward a central point so as to resist forces in both side to side and also in end to end directions."

  "description_excerpt": "The present invention generally relates to systems and methods for mobile rock crushing and/or screening plants.\n\nThis invention relates to mobile rock crushing and/or screening plants. A portable rock crushing and/or screening processing plant is either a single crusher or screen or a collection of several units, each performing various material processing functions to prepare aggregate materials for use for, but not limited to, concrete and asphalt products. The various units can perform various stages of crushing, screening, conveying, and washing of aggregate and recycle materials. Portability is achieved by positioning the plants on towable or haulable modules, so that the plant can service multiple locations where processed materials can be produced.\n\nMany plants have utilized with run-on and/or leveling jacks to level the crusher or screen and/or reduce vibration of the plant.\n\nWhile such systems have enjoyed some commercial success in the industry, they have drawbacks.\n\nTraditionally, these jacks will wiggle due to clearances between telescoping portions of the jack. One method of reducing the vibration in such systems was to provide some type of structure to clamp together or otherwise limit the vibration induced relative motion of the telescoping jack portions after the jack length has been adjusted to a desired configuration. These approaches require some extra structure, such as pins and pin receiving members, clamps, etc. to achieve this result. Moreover, it requires time to make the required actions to clamp or otherwise limit the motion.",
