Over-long boom (50/55m) ; wide range of coverage.
Heavy in section of mast section(1600 by 1600 or 1800 by 1800), good steel performance, complete crane is stable and little swing as load.
Main material of mast section is 160 by 160 by 16 or 125 by 125 by 10 or 135 by 135 by 10square tube.
Electric system adopts domestic fine quality or import components, performance is stable and reliable.
Mast section, tie bar, upper and lower bracket and so on main parts all adopt CO2, GSAW with large in weld penetration, small in transformative, mast section can exchange combination.
Hoisting mechanism has good speed governing performance, rise and fall are stable, shockless. Swing mechanism adopts winding motor, operating balance, efficient, fast and convenient in position.
