额定起重量

选取既能满足强度又能满足稳定性要求的起重量，来作为相应工况下的额定起重量。

Lifting capacity which meets the requirements of strength and stability is selected as the rated load in relevant I mode .

为此，如何设计更为合理的抓斗形式，充分利用起重机的额定起重量，提高抓取比，成为当今我们抓斗设计的一大课题。

Therefore , how to designing more reasonable grab type , making the best of the rated load of the port machine , increasing the parameter of grab 's performance , has been a grand task for grab design .
