3. Interpretation of core parameters and application cases

3.1 Maximum lifting weight series (Table 1)

Maximum lifting weight series: Table 1 lists the recommended maximum lifting weights of lifting machinery, ranging from 0.1 tons to more than 5,000 tons. It is particularly important to note that the values in brackets are non-preferred values. In actual applications, the non-bracketed parameters indicated in the table should be selected as much as possible.

3.2 Span and gauge series (Table 2)

Span and gauge: Table 2 specifies the preferred span values for bridge cranes and gantry cranes, and allows for negotiation and adjustment based on actual needs. For example, the span can be selected from standard values such as 7 meters, 9 meters, and 16 meters, and the gauge of the jib crane can also be implemented by reference.

3.3 Amplitude series (Table 3)

Amplitude series: Table 3 provides recommended values for the amplitude range of lifting machinery, which is applicable to different types of cranes. For example, the amplitude can select standard values such as 2 meters, 6 meters, and 28 meters, and it is allowed to adjust every 5 meters when it is greater than 100 meters.
