Double Arm Floating Suction Unit

When a tank is taller than it is wide, a single straight arm cannot reach the top filling level. The Vens double arm floating suction unit uses two arms joined by an intermediate swivel, so the assembly folds like an elbow as the level falls and opens out as the tank fills.
The lower arm turns on a swivel joint at the tank outlet and the upper arm carries the pontoons and the suction inlet just below the surface. The geometry is set so the arms cannot lock in a straight vertical line, and floor supports carry the assembly at low level.
