Pit Depth Pit Depth = 4′ -0″ • Overhead Minimum Overhead (See Below) • Cab Height = 8′ -0″

Guidelines for determining overhead required:

For 3 Stage Jack

  • Car Speed = Up to 150 FPM
  • Top Overtravel = 12″
  • Bottom Overtravel = 8″
  • Pit Depth = 4′ -0″
  • Cab Height = 8′ -0″

3 Stage Jack Overhead Requirement:

Minimum of 12′ -8″ overhead required for 30′ -6″ of travel and under. Add 11/32” to 12′ -8″ for every additional 1″ of travel over 30′ -6″.


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 telescopic jacks are located on each side of the car.

  • 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.
  • Less overhead required than 2 stage holeless
