Extra long jib(50/48m), large coverage area, chaneable.

Large standard section(1615*1615),(1500*1500), good rigidity, stable complete machine when loading and swing small.

Large material type of standard main jib(160*160*12/140*140*12)

The system of the electric apparatus adopts the high-grade or imported components with stable and reliable performance.

The main pieces(parts)such as section, tie rod and upper and lower frame etc all adopt CO2, gas shielded welding with deep weld penetration.

Slewing mechanism adopts wound-rotor motor with stable and reliable strating and no impact, and the arm with the length of 50 madopts double rotation.

The hoisting mechanism has good perfornace of speed regulation with no impact and smooth operation during the hoisting and descending.
