ESTIMATION SYSTEM AND METHOD FOR SLUMP VALUE OF READY MIXED CONCRETE, MIXER, TRUCK MIXER, AND GRASPING SYSTEM FOR SLUMP VALUE OF READY MIXED CONCRETE

摘要

PROBLEM TO BE SOLVED: To estimate a slump value of ready mixed concrete more accurately.;SOLUTION: There is provided an estimation system 100 for slump value of ready mixed concrete that estimates a slump value of ready mixed concrete cast in a drum 22 of a truck mixer 10, the system including an oil pressure measurement part which measures drive oil pressure of a hydraulic motor 24 driving and rotating the drum 22, an angle measurement part which measures a tilt angle of the truck mixer 10 in a front-rear direction, a storage part which stores relation information representing the relation among drive oil pressure, a tilt angle, and a slump value, and a slump value calculation part which calculates a slump value corresponding to the drive oil pressure measured by the oil pressure measurement part and the tilt angle measured by the angle measurement part based upon the relation information stored in the storage part.;COPYRIGHT: (C)2014,JPO&INPIT
