Cranes - Classification - Part 5: Overhead travelling
and portal bridge cranes
1 Scope
This Part of GB/T 20863 specifies the classification of overhead travelling and
portal bridge cranes according to the number of work cycles that are completed
by the crane and its mechanism during the expected life and the load spectrum
coefficient representing the nominal load state.

GB/T 20863.1, Cranes - Classification - Part 1: General (GB/T 20863.1-2007,
ISO 4301-1:1986, Cranes and lifting appliance - Classification - Part 1:
General, IDT)
3 Working level
The whole crane and its mechanism shall be classified according to GB/T
20863.1.
The general principles of the classification of overhead travelling and portal
bridge cranes according to the conditions of use are shown in Table 1.
When the crane's service level and load status are unknown, the working level
of the crane should be considered in accordance with the lowest working level
of the same type of crane.
