• • With each section fully retracted, the boom of the TTC025G truck crane is about 11m long while lifting. If the length of the boom is beyond the specified values, the hoisting machine with short boom bears more load than that with longer one.
  • The tabulated load includes the weight of hooks. Therein, the main hook weighs 543kg and the auxiliary hook weighs 102kg. While the jib is extended, the rated lifting load capacity of the main boom should be reduced by 1500kg. When the main hook is at the head of main boom, the lifting capacity of the jib has to be reduced by 543kg.
  • If the head pulley is adopted, the rated lifting capacity at each section must be reduced by 543kg, but the maximum lifting capacity of the truck crane is 4000kg. As the main hook is used when the auxiliary hook is at the head of pulley at the end of the boom, the rated lifting weight of each part of the lifting boom should be reduced by 102kg.

When the fifth outrigger is used, the truck crane keeps tabulated rated lifting capacity rotating within 360°.

The minimum boom angle of elevation is listed in the table based on different boom length. It is strictly banned to elevate the boom below the corresponding minimum angle.
