BOOM RAISING MECHANISM OF BUCKET-TYPE EXCAVATOR FOR BUILDING DEMOLITION
PROBLEM TO BE SOLVED: To provide a boom raising mechanism of a simple structure, capable of extending a boom used in a bucket-type excavator and others from a prescribed height of the boom to a desired height.SOLUTION: A bucket-type excavator has a boom fitted on a swing post installed on a base, a working arm fitted on an end of the boom, and a bucket fitted on an end of the working arm, each in a way that allows swinging, and cylinders are fitted along the boom and the working arm, between the swing post and the boom, between the boom and the working arm, and between the working arm and the bucket. A boom raising mechanism for the bucket-type excavator has a riser pole fitted detachably between the swing post and the boom for dividing the boom into a lower boom and an upper boom, and the boom position may be switched as appropriate between a standard fitting position in which the lower boom and the upper boom form an angle and a straight fitting position in which the lower boom and the upper boom are extended straight.
【課題】バケット式掘削機等に用いられる所定高さのブームを、簡単な構造で所望の高さまで伸長することができるようにしたブームかさ上げ機構を提供する。【解決手段】基台に設けたスイングポスト上にブームを、該ブームの先端に作業用アームを、該作業用アームの先端にバケットをそれぞれ首振り自在に取付けるとともに、前記スイングポストとブームとの間、前記ブームと作業用アームとの間、該作業用アームとバケットとの間にそれぞれ前記ブームおよび作業用アームに沿ってシリンダを取り付けたバケット式掘削機において、前記スイングポストとブームとの中間に立上げポールを着脱可能に取り付け、前記ブームを元ブームと先ブームとに２分割し、該元ブームと先ブームとをくの字状に屈曲した標準取付位置と直線的に伸ばしたストレート取付位置とを適宜切り替えられるようにしたバケット式掘削機のブームかさ上げ機構。【選択図】図３
