About Elevators
HOLED HYDRAULIC
Otis' Holed Hydraulic system provides safe operation, reliability and consistent ride quality for rises up to 60 feet.
In Holed Hydraulic systems, a car is connected to the top of a piston that moves up and down in a cylinder. Movement is controlled by a hydraulic valve. As fluid is pumped into the cylinder, the car rises; as the fluid returns to the reservoir, the car lowers.
The 'soft-start' motor provides precise control while reducing demands on a building's electrical system. And Otis' double-bottom cylinder with sealed PVC protection lowers the risk of soil and ground-water contamination caused by corrosion.
Double-bottom cylinder with sealed PVC protection

Otis' sealed PVC protection provides a means to monitor the space between the cylinder wall and the PVC. Its evacuation port enables the removal of liquids that may collect between the PVC protection and the cylinder.
