Counterweight Operated Hose Retriever [1]

In a counterweight operated hose retriever, the rope or wire cable clamped to the hose is led over a pulley mounted at the top of a pole and fastened to a counterweight at the other end. The counterweight rises and falls in response to the movement of the dispensing hose, minimizing the slack in the hose at all times.
