Pit Depth Pit Depth = 4′ -0″ • Overhead Minimum Overhead (See Below), Denotes Minimum Overhead = 12′ -5″
• Cab Height = 8′ -0″ • **Hoistway width may vary for two-stage.

Guidelines for determining overhead required:
For 1 Stage Jack:

  1. Car Speed = Up to 150 FPM
  2. Top Overtravel = 5″
  3. Bottom Overtravel = 12″
  4. Pit Depth = 4′ -0″
  5. Cab Height = 8′ -0″

 

For 2 Stage Jack:

  1. Car Speed = Up to 150 FPM
  2. Top Overtravel = 12″
  3. Bottom Overtravel = 10′
  4. Pit Depth = 4′ -0″
  5. Cab Height = 8′ -0″

 

One Stage Jack Overhead Requirement:
Minimum of 12′ -0″ overhead required for 12′ -0″ of travel and under. If over 12′ -0″ travel, overhead must equal or be greater than total travel.
Two Stage Jack Overhead Requirement:
Minimum of 12′ -8″ overhead required for 20′ of travel and under. Add 1/2” to 12′ -8″ for ever additional 1″ of travel over 20′ -0″

Code year adoptions and local code variations may affect the hoistway size. Verify all dimensions with MEI prior to construction.

This design utilizes two hydraulic jacks and provides maximum structural stability. The jacks, located on each side of the car, are either single-stage or telescopic. The appropriate jack type is determined by the amount of travel and the project conditions. The single-stage jacks are popular for two-stop arrangements, while telescopic jacks are generally used for three- and four-stop projects.

  • No jack hole is required. This eliminates the cost of drilling and the risk of oil contamination.
  • Accommodates front and rear openings in any configuration.
  • Available for both low and high capacity cars.
