Improved device for cab base
The invention relates to an improved device for a cab base. A rack which is composed of a rear rack body and a front rack body is mainly characterized in that a hinge is fixed to the upper portion of the rack, the other half of the hinge is hinged to the right side of the cab base, a screw hole is formed in one side of the lower end of the rack, a buffer pad is arranged in the upper end of the rack, the inner side of the rack is connected with a lifting jack, the end of an ejector rod of the lifting jack is connected with one side of the lower end of the rack, and the lifting jack is connected with a manual jacking pump on the rack through a pipeline. When a part mounted on the lower portion of a cab is damaged, the manual jacking pump can be arranged at a lifting extension position, then the manual jacking pump is jacked, the manual jacking pump outputs high pressure oil which enters the lifting jack, the ejector rod of the lifting jack is made to push the left side of the cab to be jacked upwards, in this way, the space on the lower portion of the cab is made large, and thus maintenance operation by people is facilitated.
