The utility model provides an engineering machinery can alleviate the burden of hydraulic piping when the utility model provides an engineering machinery vibrates, can restrain hydraulic piping and structure contact on every side to can restrain the damage of hydraulic piping. The portion midway that the coupling part (T1, T2) that possesses contrast hydraulic piping (T) and control valve (14) and rotary joint (15) more is located the hydraulic piping T of below carries out keep parts (16) that keep and is used for the supporting institution in bearing surface (21c) the upper support keep parts (16) of saddle (11) at preset. The supporting institution is following state with keep parts (16) supporting, promptly: upwards separate from bearing surface (21c) keep parts (16), and restriction keep parts (16) removes and allow the state that keep parts (16) removes for the direction of saddle (11) beyond specific direction for saddle (11) in specific direction. |
