3.3 MACHINE FUNCTIONS
[1] CARRIER
• The carrier is of a crawler type, which facilitates running in rough terrain and soft ground.
• Operating the two travelling levers enables not only travelling direction changes (forward,
backward, right and left) but also pivot turns and spin turns.
[2] UPPER SLEWING BODY
• The upper slewing body is allowed to perform 360 degrees slewing by slewing operation.
• Through the combined use of the telescopic boom, derrick and slewing systems besides the
winch system, the crane can raise and lower the hook block to move the lifted object to the
desired position within the rated total load and the specified working envelope.
