Mast Sizes (Genesis OPAL)

From Garaventapedia

The mast size required for a particular site is determined by the vertical distance between the upper and lower landings.

When the site is measured, the lift height “H” is always defined as the distance from the lower finished floor or bottom of pit to the finished floor of the upper landing as shown in the diagram below. If the lift is to be mounted directly on the surface of the lower landing and an entry ramp (stationary or folding) is used, then “H” equals the elevation change between the upper and lower landings. If the lift is pit mounted, then the measurement “H” is 76mm (3”) greater than the elevation change between landings. This measurement is crucial for your lift so be certain the height you provide is accurate.

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
(see note below)
GVL - 42 1143mm (45") 1737mm (68 3/8") 1572mm (61 7/8”)
GVL - 60 1600mm (63”) 2194mm (86 3/8") 2029mm (79 7/8”)
GVL - 72 1905mm (75”) 2498mm (98 3/8”) 2333mm (91 7/8”)
GVL - 96** 2515mm (99”) 3108mm (122 3/8”) 2943mm (115 7/8”)


  • The standard width of all masts is 998mm (39 1/4”).
  • **Not compliant to US code, ASME A18.1-2003 only allows unenclosed lifts up to 60” of travel.
