Description

発明の詳細な説明Detailed Description of the Invention

産業上の利用分野Industrial application fields

本発明は従来の油圧ショベル又は、垂直掘りテレスコープクラム又は、解体用ハイリフト等に応用が可能とする メンテナンス向上機構  The present invention can be applied to a conventional hydraulic excavator, a vertical digging telescope crumb, a high lift for dismantling, or the like.

従来の油圧ショベルにおいて（図１） ▲１５▼自走体上部に運転室上部本体が設けられ自走体に対し運転室上部本体は左右方向に旋回する構成である。運転室上部本体では▲４▼カウンターウエイト ▲２▼燃料タンク ▲３▼油圧作動油タンク ▲１▼ブーム等が独立設置されているIn the conventional hydraulic excavator (FIG. 1) (15) The cab upper main body is provided on the upper part of the self-propelled body, and the cab upper main body turns in the left-right direction with respect to the self-propelled body. (4) Counterweight (2) Fuel tank (3) Hydraulic oil tank (1) Boom etc. are installed independently in the upper body of the cab

発明が解決しようとする課題Problems to be solved by the invention

運転室上部本体中心部ではスイヘルジョイント（走行油圧回路）旋回モーター、メインコントロールバルブ又は、油圧配管等が密集しており作業上トラブル発生時瞬時に対応ができないと共にメンテナンス員に対しても火傷、はさまれ等の危険性がある。たとえば破損場所により手が届かない所ではその他の部分を分解する必要性があり時間的なコストがかかる  The swivel joint (running hydraulic circuit) swivel motor, main control valve, or hydraulic piping, etc. are densely packed in the center of the cab upper body. There is a danger of being pinched. For example, it is necessary to disassemble other parts in a place that is out of reach due to the damaged place, which costs time
