Description
請求項2においては、請求項1記載の掘削作業機のブームにおいて、前記ブーム支点部(16)、ブームシリンダーロッド支点部(18)及びアーム支点部(19)は同一とし、前記第一ストレート角型管(61)と第二ストレート角型管(62)により構成した標準ブーム(15)に対して、前記ストレート角型管(61・62)の少なくとも一方の長さを変更して、ロングストレート角型管(71・72)を構成し、該ロングストレート角型管(71・72)により、ロングブーム(51)を構成し、該ロングブーム(51)を前記上部旋回体(30)に装着可能としたものである。
すなわち、ブームの部品数を削減することができる。また、汎用の角型管の採用並びに部品数の削減により部品コストが削減できる。また、汎用の角型管を用いることで溶接箇所が削減するので製造工数が削減できる。
つまり、掘削作業機におけるブームの汎用性を向上できる。
