★ Description of the lifting weight in the above lifting performance table

1) The value indicated by the rated lifting capacity in the table is the maximum lifting capacity that the crane can guarantee on a flat and solid ground. The starting amount does not exceed 75% of the tipping load;

2) The rated lifting weight in the table includes the weight of the hook and spreader;

3) The working range in the table is the actual value including the deformation amount of the boom, so the lifting work must be carried out based on the working range;

4) 75% of the tipping load considering wind 6, i.e. pressure of 125N / m allows up crane legs still fight when six jobs wind, and prohibits operation of the tire with the carrier tape job.
