Holed
Direct System
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 Two Speed Valve and
Submersible motor provides precise control while reducing demands on
a building's electrical system and our Fiber Coated Cylinder lowers
the risk of soil and ground-water contamination caused by corrosion.
Key Attributes
• Well hole drilling required
• Fiber Coating protection surrounds wall and bottom of in-ground
cylinder to prevent contact with
underground
contaminants
• Solid-state starter improves performance through precise control
of electric current
• Available in both passenger and service elevator configurations
and capacities
