Abstract
PURPOSE: To control a pump variably driving a bucket for controlling the attitude of the bucket by using control signals from swash plate-position signal for at least one of variable pumps and a signal based on a given function during the operation of at least one of boom and arm.
CONSTITUTION: At first, when a bucket is not controlled, switches 52 and 53 are turned into OFF. Then, when the attitude of the bucket is controlled, the switches 52 and 53 are closed. And, when a boom lever 39 and an arm lever 40 are concurrently or singly operated, each cylinder is operated according to the operating amount of each, and the attitude of the bucket is also operated correspondingly. In this case, when a bucket lever is operated, the signal obtained by multiplying the signals of each function generator by multipliers 55 and 56 and the signal of the lever 41 are added to the swash plate-position signals of each pump at an adder 54, and by the signals, the pump 19 driving the bucket is controlled.
