SYSTEM AND METHODS FOR WITH A FIRST AND A SECOND HAND OPERATED CONTROL, CONTROLLING MOTION ON A WORK TOOL FOR A CONSTRUCTION MACHINE

摘要

The present invention relates to a kind of systems and a kind of method, have first and second to manually control means (11a, 11), deflection Work tool (5) engineering machinery (1) of operating mechanism. Building machinery (1) includes a lower bracket (2), top (3), digging arm (4) and Work tool (5). Digging arm (4) includes that internal arms (4a) there is the first inner link arm end (4a1,4a2) and exterior chain joint arm (4b) to have the first exterior chain joint arm end (4b1,4b2). The Work tool (5) is fixed on the second outer link arm end (4b2), and via auxiliary equipment (6), it enables controlled rotation and controlled inclined work tool (5) relative to outer webs (4b). The system is characterized in that, first manual control means (11a) are intended to control the second outer plate of position, and (11 are intended to function (5) tool of rate-determining steps b), including controlled rotation and controlled inclined work tool (5) relative to outer webs (4b) with above-mentioned second-hand SERVO CONTROL (4b2) arm end tool.
