ENGINE SUPPORT METHOD AND ENGINE SUPPORT STRUCTURE IN CONSTRUCTION MACHINE
PROBLEM TO BE SOLVED: To facilitate position adjustment work and fixation work for an engine support member in the case of supporting an engine on a revolving frame via the engine support member and an engine mount that is fitted on the engine support member and has a vibration prevention function.SOLUTION: An engine support member is configured using: support plates 19X, 19Y fixed on lengthwise frames (center lengthwise frame, side lengthwise frame) 11R, 12R constituting a vehicle body frame in a state in which the plates are positionally adjusted in the vertical direction; and L-shaped mount fitting brackets 18A to 18D including top plates 18Ab to 18Db on which engine mount fitting holes 18Aa to 18Da are formed and hanging plates 18Ac to 18Dc hanging from the top plates Ab to 18Db, the mount fitting brackets being fixed on the support plates 19X, 19Y and the longitudinal frames 11R, 12R in a state in which the engine mount fitting holes 18Aa to 18Da are positionally adjusted in longitudinal and lateral directions.SELECTED DRAWING: Figure 5
【課題】エンジンを、防振機能を有したエンジンマウントと、該エンジンマウントが取付けられるエンジン支持部材とを介して旋回フレームに支持する場合に、エンジン支持部材の位置調整作業および固定作業を容易にする。【解決手段】エンジン支持部材を、車体フレームを構成する縦フレーム（センター縦フレーム、サイド縦フレーム）１１Ｒ、１２Ｒに上下方向の位置調整がなされた状態で固定される支持板１９Ｘ、１９Ｙと、エンジンマウント取付孔１８Ａａ〜１８Ｄａが形成された天板１８Ａｂ〜１８Ｄｂおよび天板Ａｂ〜１８Ｄｂから垂下される垂下板１８Ａｃ〜１８Ｄｃを備えたＬ字形状をし、エンジンマウント取付孔１８Ａａ〜１８Ｄａの前後左右方向の位置調整がなされた状態で支持板１９Ｘ、１９Ｙおよび縦フレーム１１Ｒ、１２Ｒに固定されるマウント取付ブラケット１８Ａ〜１８Ｄとを用いて構成した。【選択図】図５
