Title:
ESTIMATION DEVICE OF GROUND STRENGTH OF OUTRIGGER GROUNDING SOIL OF MOBILE VEHICLE, AND ESTIMATION METHOD OF GROUND STRENGTH OF OUTRIGGER GROUNDING SOIL OF MOBILE VEHICLE
Document Type and Number:
Japanese Patent JP2019031111
Kind Code:
A
Abstract:
To provide an estimation device of ground strength of outrigger grounding soil of a mobile vehicle capable of estimating the ground strength by a simple constitution without remodeling greatly the outrigger itself.SOLUTION: An estimation device D of ground strength includes a vehicle body part 10, a boom 14 loaded on the vehicle body part 10, an outrigger 11 for supporting the vehicle body part 10, a reaction measuring instrument 20 for measuring reaction R of the outrigger 11, an inclination angle measuring instrument 90 for measuring an inclination angle θ of the vehicle body part 10, a length measuring instrument 31 for measuring the length L of a jack of the outrigger 11, and a controller 70 for calculating the ground strength based on the reaction R of the outrigger 11, on the inclination angle θ of the vehicle body part 10, and on the length L of the jack.SELECTED DRAWING: Figure 1
