Matters needing attention in the selection Overhead Travelling Cranes

 Overhead Travelling Cranes

1. The user shall make appropriate requirements for the working level of the Overhead Travelling Crane in accordance with this standard, If possible, it is necessary to improve the working level of the Overhead Travelling Cranes. To ensure that the manufacturer can design and manufacture in accordance with this requirement;

2. Working grade of Overhead Travelling Cranes. Two factors are determined by Overhead Travelling Crane usage grade and Overhead Travelling Crane load state level. The use grade of the Overhead Travelling Crane indicates the working busy degree of the Overhead Travelling Crane. It is determined by the total working cycle number of the Overhead Travelling Crane , It can be used by Overhead Travelling Crane expected years (before the Overhead Travelling Crane scrap or be updated using a number of years), the average number of working days a year, Every working day average number of lifting work cycle, the number of three products obtained. The level of the Overhead Travelling Crane's load state indicates the degree of the Overhead Travelling Crane's lifting load.

Note: these two calculations need only be estimated. There is no need for very accurate calculations.

3. The work level of Overhead Travelling Crane,  each agency as a separate assessment conducted. It represents the overall working condition of the mechanism determined by its use grade I design life, number of hours of work) and its load state level f, which reflects the level of load state or load spectrum). In the same way, the calculation of the use grade and the load state level of the mechanism only needs to be estimated, and no very accurate calculation is needed.

4. If the user is unable to provide the relevant data of the Overhead Travelling Crane required, it is not possible to select the working level of the Overhead Travelling Crane or its mechanism by calculating and looking up the table according to the universal method described in 2 / 3 above. By referring to the relevant information in Appendix A and Appendix B, you can also roughly select the working level of the Overhead Travelling Crane and its mechanism. However , it must be noted that these selection guidelines in Appendix A and Appendix B are not binding and are merely examples of the selected reference . In the Overhead Travelling Crane tender and order form on the Overhead Travelling Crane identified its work level institutions, Only by the Overhead Travelling Crane user and make the final determination

5. The Overhead Travelling Crane users shall specify the weight , span , hoisting height and working level to be selected in order to provide technical information such as workshop and site working environment and usage status .
