Operator’s Manual for Crawler Crane
3.11.5 Crane operation
a) Operating conditions
1) All components of the crane are in running-in state at the initial operating period. So,
for the first 100 operating hours, the working load should not be too great and the
working speed should not be too high. The maximum lifting load cannot exceed 80%
of its rated load. And the maximum working speed is forbidden.
Figure 3-79
2) The ground on jobsite should be firm and flat and the gradient should not be greater
than 5/1000. The complete vehicle should be level and the supporting ground should
not collapse during operation. If the ground is soft, the steel plates should be placed
under the track pad.
