The machine is equipped with an air self-unloading device, which can realize air disarming; high power, stable rotation, strong wind resistance, high speed and high efficiency; standard section main chord adopts angle steel main chord angle steel square and inclined web Steel pipe; square boring head and pin shaft connection, not only beautiful appearance, but also small windward area and good rigidity, which is beneficial to reduce the load of the tower crane, improve the stability of the tower crane, and the force is more reasonable. The crane operation is safer and more reliable. The hook can automatically change the magnification and the switching efficiency is high; the introduction platform of the climbing frame adopts the introduction, and the work is safer and more reliable.
