Foreword
This standard replaces JB/T 1306-1994 “Electric single girder crane”.
As compared with JB/T 1306-1994, the main changes of this standard are as
follows.
- MODIFY the contents of the normative references;
- EXTEND the rated voltage and rated frequency of the main circuit of the
crane from the original 380V and 50Hz to 220V ~ 660V, 50Hz or 60Hz;
- MAKE additions and adjustments for such basic parameters as the rated
capacity, span, and working speed, etc;
- CANCEL the model representation and marking examples;
- CANCEL the Appendix A and Appendix B.
This standard was proposed by the China Machinery Industry Federation.
This standard shall be under the jurisdiction of the National Hoisting Machinery
Standardization Technical Committee (SAC/TC 227).
