  • Hatch depth can be reduced by 1" to 5'-9" clear front to back.
  • 2000-lb. car complies with NEII recommendations for car to accommodate wheelchair.
  • 2500-lb. car complies with NEII recommendations for car to accommodate ambulance size stretcher.

 

MACHINE ROOM

  • An area 5’-6" x 7’-0" x 8’-0" high is adequate with 3’-0" wide door opening for access.
  • All materials are furnished for machine room located adjacent to elevator hoistway at lowest landing.
  • Adequate heating and ventilation to meet code requirements must be provided.

Calculation of Pit, Overhead, Hole Depth Requirements

All jack units are built for "even" foot increments. Therefore, for "travel" values in following formulas, round floor to floor travel up to next even foot (i.e., for 12’-6"- use 13’-0").

FOR 2-STOP HOLELESS

Maximum floor to floor distance available is 16’-0"

  • Pit depth - 4’-0" minimum is standard.
  • Minimum clear Overhead required by code (based on 8’-0" high cab):
    For up to 100 FPM = 11’-11".
    For 100 FPM and over = 12’-12".
  • Total hoistway height required (pit floor to clear under roof) is:
    For up to 100 FPM: (2) x (FL to FL travel) + 2'-6''.
    For 100 FPM and over: (2) x (FL to FL travel) +3'-8''.

If total hoistway height is not sufficient, (2) holes can be provided to make up required dimension. In this case, add an additional 6" to required height.

For up to 100 FPM - add 3’-0" in lieu of 2’-6".

For 100 FPM and over - add 4’-2" in lieu of 3’-8".

(If "open" holes are provided - jack unit sits on pad at bottom of hole - do not add additional 6".)
Note that clear Overhead as required by code must always be maintained.

For example (FOR HOLELESS ONLY):

For FL to FL distance of 15’-4" use 16’-0"
Speed of 90 FPM, Pit 4’-0", Overhead 13’-0"

Available     Required  
Actual FL to FL 15'-4"   (2) Travel = (2) 16'-0" = 32'-0"
Pit 4'-0"   Over FPM +2'-6"
O.H. 13'-0"     34'-4"
  32'-4"   Available 32'-4"
      Holes required 2'-2"
      Additional add 6"
      Hole depth required 2'-8"

 

FOR 3 STOP HOLELESS

Maximum floor to floor distance available is 39’-0"

100 FPM
(1/2 Travel) + 58" = Pit and Overhead required.
Minimum Overhead is 12'-6"
Minimum Pit is 4'-0".

125 FPM
(1/2 Travel) + 67" = Pit & Overhead required.
Minimum Overhead is 12'-9".
Minimum Pit is 4'-0".

FOR HOLED INSTALLATIONS

Maximum floor to floor distance available is 26’-0"

  • Pit depth - 4’-0" minimum is standard.
  • Hole depth from lower terminal landing is approximate Travel + 6'-0".
  • Minimum clear Overhead required (based on 8'-0" high cab):
    For up to 100 FRM = 11'-10".
    For 100 FPM and over = 12'-1".
