PROBLEM TO BE SOLVED: To enhance a safety degree when using a movement work machine.SOLUTION: The present invention relates to a caterpillar drive assembly 8 for a work machine, especially, for a crawler crane or a crawler drilling machine, in which the caterpillar drive assembly comprises: a crawler frame 2; a crawler track 3; a drive wheel 4; a guide wheel 1; and an aggregate of rotation wheels coupled to the crawler frame 2. The caterpillar drive assembly comprises a sensor system comprising sensors for outside rotation wheels coupled to the drive wheels and guide wheel, out of the aggregate of the rotation wheels, and for each of at least one rotation wheel disposed between the outside rotation wheels, respectively, in which the force transmitted to the crawler track via the respective rotation wheel can be determined by using the sensor. The method and step for determining distribution of ground contact pressure under the work machine, especially crawler crane or crawler drilling machine, are also provided.SELECTED DRAWING: Figure 1 |
