LOADING APPARATUS FOR WHEEL LOADER
PROBLEM TO BE SOLVED: To provide a loading apparatus in which a tilt angle of a bucket is stabilized.SOLUTION: A loading apparatus for a wheel loader comprises a linking mechanism which is so designed that a criterion point of a bucket moves in parallel with the ground. It comprises a tilt stopper working state detecting part 23 detecting a tilt stopper working state of the bucket, a communication/shutoff valve 17 witching a lift cylinder bottom room side oil path 13A for supplying pressurized oil to a lift cylinder bottom room 13a and a tilt cylinder rod room side oil path 14B for supplying pressurized oil to a tilt cylinder rod room 14b between a communication position where they are communicated each other and a shutoff position where they are shutoff, and a controlling part 22 switching the communication/shutoff valve 17 to the communication position when at least the tilt stopper sensor 23 detects the tilt stopper working state.SELECTED DRAWING: Figure 6
【課題】バケットのチルト角の安定した荷役装置を提供する。【解決手段】ホイールローダの荷役装置は、バケットの基準点が地面に対して平行に移動するように設計されたリンク機構を備える。バケットがチルトストッパ作動状態であることを検出するチルトストッパ作動状態検出部２３と、リフトシリンダボトム室１３ａへ圧油を供給するリフトシリンダボトム室側油路１３Ａおよびチルトシリンダロッド室１４ｂへ圧油を供給するチルトシリンダロッド室側油路１４Ｂを互いに連通する連通位置と互いに遮断する遮断位置に切換えられる連通／遮断弁１７と、少なくともチルトストッパセンサ２３がチルトストッパ作動状態を検出すると連通／遮断弁１７を連通位置に切換える制御部２２とを備える。【選択図】図６
