The invention relates to a method for controlling a crane, the method comprising defining, at each time, the distance the crane moves before stopping and without swinging of the load fastened to it by summing up a stopping distance, which is calculated on the basis of the internal target velocity, i. The inventive iron-based alloy is based on the observation that by very tightly controlling the composition of the metalloid moiety of the Fe-based, P-containing bulk metallic glass alloys it is possible to obtain highly processable alloys with surprisingly low shear modulus and high toughness. The second leg has a valve arrangement to prevent fluid flow through the second leg from the stent graft. The initial separation can be performed by way of incision, perforation and the like.
