Wire rope ratio

Value specified in table is rated lifting capacity of the crane under the condition that the crane parks on the flat and solid ground under leveling state;

Values above the thick solid line are determined by the strength of the crane and below the thick solid line are determined by the stability of the

crane;

Rated lifting capacity determined by the stability shall comply with ISO4305;

Rated lifting capacity in the table includes the weights of lifting hook and hanger (main hook: 320 kg; auxiliary hook: 90 kg)

Rated lifting capacity when pulley at boom tip is used can not exceed _3500_kg; after the jib installs, rated lifting capacity of the boom shall be a

value that a total is subtracted by the weight of jib (450 kg);

If actual boom length and range are both between two values in the table, the larger value is used to determine the lifting capacity;
