What a Pipe of Water Can Do. When the conductor in a hydraulic elevator wants the cage to go down, he pulls the rope to raise the plug. The high-pressure water is then shut off, and the water in the cylinder runs away, so that the plunger rod slides down, bringing the cage with it. It must be clearly understood that the rope does not pull the cage up or down. It simply moves the plug, and the water provides the power to drive the cage. the cage can be stopped at any desired point by moving the plug so that it shuts both the high-pressure pipe and the waste-water pipe. In many elevators, the plunger rod, instead of being under the cage, is arranged at the side.
