Erik: The specification format changed over the years. For the 922A the lift capacity was 16,500 lb at ground level and 8,500 lb at max height. This is a hydraulic capacity, the machine will tip (raise rear wheels) at less than 16,500 lb load. The exact tipping load depends on engine and counterweight options. The 922B has increase wheelbase, 78" --> 86", and thus greater actual lift capacity. For the B the tipping load is listed as 10,500 lbs., but again depends on engine and counterweight options.
