8. A crane comprising:
- a lower traveling body;
an upper rotating body rotatably mounted on the lower traveling body, the upper rotating body constituting a base machine together with the lower traveling body;
a weight mounted on the base machine; and
an overload preventing apparatus installed to the upper rotating body, the overload preventing apparatus performing an overload preventing operation based on a crane capability that has been set using mounting conditions of the weight as one factor of the crane capability, wherein the overload preventing apparatus sets the crane capability based on weight mounting conditions detected by a weight detecting apparatus comprising an identification (ID) information holding medium which is installed on the weight, and in which ID information on weight mounting conditions has been written; and
an ID reader for reading the ID information, the ID reader being installed to the upper rotating body, wherein the mounting conditions of the weight are detected by wireless communications between the ID reader and the identification information holding medium, and wherein said weight mounting conditions include the mass and the position of the weight on the base machine. - View Dependent Claims (9, 10)
