摘要： A suspension apparatus for a track-type vehicle comprises a main frame having a pair of laterally spaced track frames pivotally mounted on either side thereof through a pair of pivot shafts fixedly connected to either side thereof. The forward portions of the track frames are connected to opposite ends of an equalizer bar extending transversely therebetween through a pair of stress-relieved mounting devices into which lateral and vertical displacements of the track frames and the equalizer bar are absorbed so as to prevent "toe-in" of the track frames.

摘要： An electric hydraulic control device for controlling hydraulic cylinders of work tools in a construction vehicle, in which control valves of the hydraulic cylinders are controlled in two ways. For some work tools which need not be controlled smoothly and finely, the corresponding control valves are controlled directly by an electric signal outputted according to the position of the operation levers, and for other work tools which must be controlled smoothly and finely, the corresponding control valves are controlled through an electric servo mechanism which is operated by an electric signal representative of the amount by which the operation lever is manipulated. In addition, there is provided a detector for detecting as to whether the transmission lever is in the locked condition, and electric systems of all of the control valves are rendered inoperative when the transmission lever is in the locked condition.
