Q & A
Hydraulic elevators are elevators which are powered by a piston that travels inside a cylinder. An electric motor pumps hydraulic oil into the cylinder to move the piston. The piston smoothly lifts the elevator cab. Electrical valves control the release of the oil for a gentle descent.
Hydraulic elevators are used extensively in buildings that are up to five or six stories high, in rare cases up to eight stories. These elevators, able to operate at speeds of up to 200 ft/minute, don't require significant overhead hoisting machinery, as geared and gearless traction systems do. Traditional designs utilize a single hydraulic jack, located directly under the platform and installed in the ground. They are offered as both low and high capacity elevators, can accommodate front and rear opening configurations, and have minimal pit and overhead requirements. For heavy-duty lifting, the capacity of hydraulic elevators can be extended to over 80,000 lbs, based on application and project need.
Holed Hydraulic Elevator
With holed hydraulic systems, the elevator car is mounted on a piston that travels inside a cylinder. The cylinder extends into the ground to a depth equal to the height the elevator will rise. As hydraulic fluid is pumped into the cylinder through a valve, the car rises. As the fluid returns to the reservoir, the car descends. This system is often called Inground hydraulic.
Holeless Hydraulic Elevator
Holeless hydraulic systems use direct-acting pistons mounted inside the hoistway to raise and lower the car. Travel may dictate the depth of the pit and potential overhead clearance requirements.
