Inground Hydraulic Elevators
The Inground Hydraulic Elevator is the traditional design used for hydraulic elevators. It utilizes a single hydraulic jack installed in the ground. The hydraulic jack is located directly below the elevator car, near the center of the platform.
- Easiest elevator type to install.
- Accommodates front and rear openings with any configuration.
- No extensive pit or overhead clearance is required.
- Less moving parts, less maintenance, and lowest cost of operation.
- Cost-effective solution for low-rise buildings with only a few landings. Typically, 3-4 stories or less.
- The hydraulic cylinder should be checked during maintenance to avoid leaks that could lead to oil contamination in the ground.
- Because the hydraulic jack goes into the ground the same distance as the travel of the elevator, this option requires jack hole drilling which can be expensive and not always possible in some conditions.
