■Boom of super-length (*0/*5 meters), widely
coveringrange.
■Sizable standard knot (***0mm****0mm), good
rigidity. The complete machine is stablewith little shimmy while lifting
weightiness.
■The limb
material of the standard knot has alarge
style (**5***5**0)
■All the main piece such as standard knot,
tie, up and down tumtable adopt CO2 gasscoverage weld whose depth is big and the
deformation is small. The assembling ofstandard knot can
interchange.
■The lifting frame has good speed regulation
performance. Ascending and descending isstable without
impact.
