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 invention relates to a system and a method for, with a first and a second hand operated control means (11a, 11b), controlling movement on a work tool (5) for a construction machine (1). The construction machine (1) comprises a lower carriage (2), a top (3), a digging arm (4) and a work tool (5). The digging arm (4) comprises an inner link arm (4a) with a first and a second inner link arm end (4a1, 4a2) and an outer link arm (4b) with a first and a second outer link arm end (4b1, 4b2). The work tool (5) is secured in the second outer link arm end (4b2) via an attachment device (6) which enables controlled rotation and controlled tilting of the work tool (5) in relation to the outer link arm (4b). The system is characterized in that the first hand operated control means (11a) is intended to control the position of the second outer link arm end (4b2) and the second hand operated control means (11b) is intended to control the function of the tool (5), comprising controlled rotation and controlled tilting of the work tool (5) in relation to the outer link arm (4b).
