Image Number 3 for United States Patent #5161744.
The invention relates to a crusher unit that can be transported directly on roadways, the crusher being mounted on an elongated, rigid frame which is supported by several travel mechanisms or support trestles which rest directly on the ground underneath. The frame has several hydraulic jacks which are adjustable in height and lift the travel mechanisms or support trestles from the ground when the jacks are extended. In order to reduce the height of this crusher unit during transportation, the invention proposes that the travel mechanisms or support trestles be removed for transportation. This is achieved by means of quick-release fastening mechanisms and by arranging and dimensioning the jacks such that there is sufficient room under the frame to drive a transport vehicle which can be used on roadways.
