Total length of suspending outside is less than1/3 of the span and 90%of suspending limiting-position (Gn). In addition, the trolley cannot travel until the heavy objects moved inside the support. If the trolley must travel outside the support, its heavy objects (Gn) should reduce 10%-20%. If total length of suspending outside is more than 1/3 of the span, the heavy objects (Gn) should reduce step by step, In a word, the trolley cannot travel until the heavy objects are near the support, and the crab isn’t suitable for traveling outside the support. Wind pressure should be less than 150pa.
