 This application will accommodate front and rear openings in any configuration. A jack is mounted on each side of the car, attached to the rails. This application is the most popular for 2-stop applications but can be used for up to 3 or 4 stops with low travel dimensions. The pistons are attached to the top of the car, thus eliminating the jack hole. It can be used with both passenger and freight applications.
- No jack hole is required, thus eliminating the risk of oil contamination into the ground.
- The twin jack arrangement allows for maximum car support, which will accommodate the use of both low and high capacity applications.
- Generally the pit and overhead requirements may be greater than those required for a borehole. The greater the travel, the greater the overhead and/or pit must be.
- Hoistway width requirements are generally greater than that of a borehole, with higher capacity cars because of the jack placement between the platform and hoistway wall.
