The following chart and graphs show the speeds and air consumption for the various capacities of Frame 2 Herculink at different loads. This chart is useful in calculating cycle times when the loads are known. Choose a load on the left hand column, read across to find the up and down speeds. The graphs allow you to pinpoint speed and air flow for a selected capacity. All performance figures are based on a 980 psig (6.2 bar) at the inlet with the motors operating (dynamic vs. static). Loads are in metric tons (2200lbs/ton).
