Claim 1
Independent Claim
131 words
An eductor truck comprising a frame, a settling tank pivotally mounted on said frame, said settling tank having an eductor unit thereon, a control valve mounted on said settling tank for operating said eductor unit, said control valve being operable from a point remote from its position on the settling tank, said control valve having a control arm extending therefrom, said control arm being located outside of said eductor unit whereby it is accessible for optional manual operation, a hydraulic motor mounted adjacent the settling tank to operate the control valve, said hydraulic motor having a piston which is operatively connected to the control arm of said control valve, said hydraulic motor being remotely controlled, whereby remote operation of said hydraulic motor will operate said control valve through said control arm.
