Arm arrangement for supporting coupler section carried at end of nurse vehicle fluid transfer conduit

摘要

A sprayer nurse vehicle includes an arm arrangement which carries a coupler section that is connected to the discharge end of a fluid transfer conduit that extends from the nurse tank carried by the vehicle. The arm arrangement is constructed so that it may be extended outwardly from the nurse vehicle and moved vertically and laterally. An outer end of the arm arrangement is provided with a fluid coupler section mounting bracket that permits the coupler section to be swiveled about an upright axis and tilted about a transverse axis. A torsion bar is arranged along the transverse axis and is preloaded to counterbalance the weight of the hose and liquid contained therein so as to minimize the effort an operator must exert to tilt the fluid coupler section. The various movements of the arm arrangement and fluid coupler section mounting bracket permit the coupler section to be aligned with, and coupled to, a mating fluid coupler section carried by a sprayer vehicle when replenishing of the fluid carried by the sprayer tank is required.
