Abstract
PURPOSE: To make machine operable with the maximum working capacity by automatically switching over set up speeds according to the manipulated variable of a lever.
CONSTITUTION: Functions A1WA5 from a function generator 6 are inputted to a function selector 7, and functions corresponding to velocity stages detected with a velocity stage detector 4 are selectively outputted. Speed Vs corresponding to manipulated variable 4 detected by means of a throttle lever manipulated variable detector 2 is read out from the selected functions by means of a coefficient generator 8, and is added to a subtracter 9 as a set up value of speed. Detected value of speed Vf is further inputted to the subtracter 9, and deviation between both the values Δe is found. Controlling operation unit 11 outputs voltage according to inputted deviation voltage Δe, and switches over a solenoid valve 13 through a drive unit 12. Load on a blade 15 is thereby controlled so as to equalize both the detected and the set up speed Vf and Vs. In this way, the earth moving machine can be operated bringing maximum working capacity forth.
