AUTOMATIC OPERATING DEVICE<br />

Excavator operator has a challenging job to drive<br />

a pile vertically by keeping the pile on the linear<br />

movement. This requires the control of three<br />

different movements of boom, stick and bucket<br />

cylinder simultaneously. At the same time the angle<br />

of the pile is very difficult to see from the cabin of<br />

the excavator as a side view of the pile cannot be<br />

directly seen.<br />

<strong>Movax</strong> automatic operating device is developed to<br />

solve the problem. The main principle is that the<br />

operator controls one movement and computer<br />

controlled system takes care of the two remaining<br />

movements. This results to a linear movement of<br />

the pile.<br />

Working cycle with Auto Steering<br />

Automatic system<br />

calculates<br />

the position of the<br />

pile<br />

(distance and<br />

angle).<br />

Main boom, Stick<br />

boom and <strong>Movax</strong><br />

angles are measured<br />

by sensors.<br />

The pile is driven or<br />

extracted straight in<br />

vertical direction or<br />

in any other angle.<br />

Display unit recognises that<br />

the operator is controlling one<br />

movement (Main boom), and<br />

takes care of the two others<br />

(Stick and <strong>Movax</strong>). This is done by<br />

controlling the proportional valves.<br />

Cylinder movements<br />

are controlled by<br />

main valves.<br />

Valves of the automatic<br />

control the main valves of<br />

the excavator.<br />

Operator controls<br />

one movement<br />

(e.g. Main boom).<br />
