Crane load condition

Load condition indicates that the degree of the crane load, related to two factors, Namely the ratio of hoisting of the load and the rated load Pi/Pmax, and the ratio of the role of various hoisting load number and the general work cycles ni/N. Indicated the two relations of load spectrum factor　and Kp calculated by type:

Dans la formule :

Kp—load spectrum factorand;
ni—the effect number of load Pi;
N—general work cycles, N= ;
Pi—the I hoisting load, i=1,2….n;
Pmax—max lifting load;
m—index, in here m=3.

Crane load condition according to nominal load spectrum coefficient is divided into four (see table 2)
