In testing to AS 2359 of similar ISO standards, with single drive wheel and outrigger forklift
configurations, forklifts are allowed to tilt until the structure makes contact with the tilt surface. Testing may
then continue until the required test angle is reached. However, in travel, if the unit tilted till the structure hit
the ground, a moment would be generated that would tend to cause the unit to pivot about the point of
contact. This has the possibility of making the situation worse.
