Genesis Enclosure and Shaftway Lifting Heights

From Garaventapedia

The mast size required for a particular site is determined by the vertical travel required between the upper and lower landings. When the site is measured, the lift height “H” is always defined as the distance from the surface at the lower landing (pit or floor) where the lift will sit to the upper landing floor as shown in the diagram below.

Floor Mount: If the lift is to be mounted directly on the surface of the lower landing and an entry ramp is used, then “H” equals the elevation change between the upper and lower landings.

Pit Mount: If the lift is pit mounted, then the measurement “H” is taken from the bottom of the pit. This should add 76mm (3”) to the elevation change between landings.

This "H" measurement is crucial for your custom designed lift. Be certain the height you provide is accurate. We recommend using the “as built” dimension.

The width of the mast is 998mm (39 1/4”) and is standard for all mast heights.

Based on the measured value of “H” the drive mast is selected as follows;

Mast Size Max. “H” Value Mast Structure Height *Mast Tieback Heigh

The diagrams below are based on a two stop lift in a pit and floor mount application. An optional three stop unit is also available.
