METHOD AND DEVICE FOR CONTROLLING A CONSTRUCTION MACHINE

摘要

A signal sending device 21 which stores therein proper data, such as an acce lerator position and a pump output, concerning operating conditions, such as supply hydraulic pressure and flow rate, appropriate for a working attachment to be attached to the front part of a hydraulic excavator or the like is mounted on the working attachment. The body of a hydraulic ex cavator is provided with a controller 11 adapted to control the hydraulic sources by receiving a nd storing proper data sent from the signal sending device 21. The signal sending device 21 include s a ROM 31 for storing proper data for each working attachment, a CPU 32 for retrieving proper data from the ROM 31, and a data communication interface (COM) 33 for receiving command signals se nt from the controller 11 of a machine body to the CPU 32 and sending to the controller 11 proper data which have been retrieved from ROM 31 by the CPU 32.
