Document Type and Number:
WIPO Patent Application WO/2011/111347
Kind Code:
A1
Abstract:
Provided is a hydraulic tubing support structure wherein a reduction is made in noises caused by pulsations of hydraulic oil in junction tubing. This hydraulic tubing support structure is provided with a floor plate (15); a driver seat (35) provided on the floor plate (15); a pair of operating levers (36) provided on both sides of the driver seat (35), said both sides consisting of a left side and a right side; a pair of remote control valves (16, 17) which generate pilot pressure for hydraulic actuators according to input operations for the operating levers (36), said pair of remote control valves (16, 17) consisting of a left remote control valve and a right remote control valve; pump tubes (P1, P2) and tank tubes (T1, T2) which extend from the remote control valves (16, 17), respectively; the junction tubing (24), which joins the pump tubes (P1, P2) to each other and the tank tubes (T1, T2) to each other, said pump tubes (P1, P2) and said tank tubes (T1, T2) being guided into an area below the floor plate (15) via through-holes (32a, 32b); and an intermediate reinforcing beam (15b) which extends in the lateral direction and is fixed to the lower surface of the floor plate (15). The junction tubing (24) is fixed to the intermediate reinforcing beam (15b) in a non-contact state with the floor plate (15).
