Boom of super-length (50/60 meters), widely covering range.
Sizable standard knot (1800mm*1800mm), good rigidity. The complete machine is stable with little shimmy while lifting weightiness.
The limb material of the standard knot is 125*125*12 buckle or square-mouth 135*135*12.
Electric apparatus system adopts domestic or imported components whose performance is stableand reliable.
All the main piece such as standard knot, tie, up and down tumtable adopt CO2 gass coverage weld whose depth is big and the deformation is small. The assembling of standard knot can interchange.
The lifting frame has good speed regulation performance. Ascending and descending is stable without impact.
The turning gear adopts winding electric machine, so it is stable and takes its place conveniently and efficiently.
