All the above value in the table is rated loading capacity on the condition that ground is flat and hard enough, the value above heavy line is mainly affected by intensity, the value below heavy line is affected by the stability. 2. The radius value is in the actual working condition, jib working radius value is in actual working condition, when main is fully extended(45m)and jib is unfolded. 3. The above value in the table is suitable for 360degree working if the 5th outrigger is extended. But keep off lifting things over the driving cab in case of dropping. 4. The above value in the table includes hook's and lifting device's. Main hook 800KG 320KG,auxiliary hook140kg. The main hook should reduce KG if jib is unfolded. 5. When the actual length or working radius is between 2 values, adopt the larger value to calculate the lifting load. 6. Prohibit luffing exceeding min.. 7. If the auxiliary hook is working, main hook is still attached to the tip, the rated load of auxiliary hook should reduce main hook's (800KG or320kg).
