Description

マスト装置２０もしくは回転皿２３のための中央位置における、図２に示すスライダ４１ａから４１ｅの位置において、比例弁３６ａから３６ｅによってそれぞれマスト装置２０もしくは回転皿２３の油圧アクチュエータを駆動することができる。これが、図３の上の中央において、良好に認識される。第１の切り替え弁装置４０ａは、マスト装置の中央の位置のＭにおいて、回転皿２３を担当する。下方の位置においてそれは、右の支持装置１６ｒと、特に前方右の支持装置１６ｒを水平に引き出すことを、担当する。一番上の位置においてそれは、左前の支持装置１６ｌを水平に引き出すことを担当し、もしくは適切な油圧アクチュエータを駆動する。切り替え弁装置４０ａが、３つの位置の１つにある場合に、制御ボックス２７を用いて正確かつ直接的に対応づけられた比例弁３６ａを適切に駆動操作することによって、上部にマスト装置２０を有する回転皿２３を１つの方向又は他の方向へ回転させることができる。他の２つの位置の１つにおいて、左前の支持装置１６ｌか、あるいは右前の支持装置１６ｒを水平方向にさらに引き出し、あるはさらに引き込むことができる。切り替え弁装置４０を切り替える前に、付属の比例弁３６の圧力をなくさなければならないことは、明らかである。 In the position of the sliders 41a to 41e shown in FIG. 2 in the central position for the mast arrangement 20 or the rotary pan 23, the hydraulic actuators of the mast arrangement 20 or the rotary pan 23 respectively can be driven by the proportional valves 36a to 36e. This is well recognized in the top center of FIG. The first switching valve device 40a serves the rotary plate 23 in the central position M of the mast device. In the lower position it is responsible for horizontally pulling out the right support device 16r and in particular the front right support device 16r. In the uppermost position it is responsible for horizontally pulling out the left front support device 16l or driving a suitable hydraulic actuator. When the changeover valve arrangement 40a is in one of three positions, the control box 27 is used to appropriately actuate the proportional valve 36a which is correctly and directly associated with the mast arrangement 20 on the upper side. A rotating plate 23 with a rotating plate 23 can be rotated in one direction or the other. In one of the other two positions, either the left front support device 16l or the right front support device 16r can be horizontally extended further or retracted further. It is clear that the associated proportional valve 36 must be depressurized before the switching valve device 40 can be switched.
