HYDRAULIC TUBING SUPPORT STRUCTURE AND OPERATING MACHINE PROVIDED THEREWITH
It is aimed to reduce noise transmitted to an operator due to pulsation of hydraulic oil in a junction tube. A hydraulic tubing support structure includes a floor plate 15, a driver's seat 35 provided on the floor plate 15, a pair of operating levers 36 provided at both left and right sides of the driver's seat 35, a pair of left and right remote control valves 16, 17 for generating pilot pressures for the plurality of hydraulic actuators in response to an input operation performed on each operating lever 36, pump-side tubes P1, P2 and tank-side tubes T1, T2 respectively extending from the respective remote control valves 16, 17, a junction tube 24 for allowing communication of the tubes P1, P2 guided to below the floor plate 15 through a through hole 32a and communication of the tubes T1, T2 guided to below the floor plate 15 through a through hole 32b, and a middle reinforcement beam 15b extending in a right-and-left direction and fixed to the lower surface of the floor plate 15. The junction tube 24 is fixed to the middle reinforcement beam 15b in a non-contact state with the floor plate 15.
