Multi-link bridge of undercarriage system to improve worker's work efficiency

摘要

The present invention relates to a multi-link type bridge of an undercarriage system that improves the work efficiency of an operator. This is the first application of multi-link to an excavator. In relation to the undercarriage system in the body structure of the excavator, the relative motion of the center frame 10 and the roller frame 20 is performed in the vertical direction by using the multi-link type bridge 30. By adding a plurality of links in an undercarriage system of a type in which the center frame 10 and the roller frame 20 are independent, the vertical and longitudinal directions of the roller frame 20 are predetermined vertically and vertically. By rotating at an angle, it is possible to prevent a rollover accident by preventing the inclination of the center frame 10 due to irregular road surface conditions, and at the same time to improve the riding comfort of the driver to improve work efficiency, and to prevent uneven wear of the track to prolong its durability. have the effect of improving it.
