 A Borehole type elevator can be utilized for front and/or front and rear openings in any configuration. Typically, the industry’s standard design, it has been in use for years. A hydraulic cylinder (jack) is installed in the ground directly under the car platform. The rails are mounted to the hoistway on each side of the car. This arrangement can accommodate high and low capacity cars for passenger and freight applications.
- Usually is the most economical of designs and material costs. A single stage cylinder must be installed in the ground roughly the same distance as the desired travel.
- The simplest installation available in comparison to the other car types available.
- Oil contamination in the ground is a possibility, however, precautions can be taken by installing the cylinder within a PVC pipe, lining the inside of the well hole. (Additional cost involved for the liner)
- A jack hole is required directly under the car. Sometimes the cost of drilling a jack hole can be costly, in some geographic areas, and is sometimes impossible in certain areas or under existing conditions.
