The telescopic arm is easier to control the vertical takeoff and landing.

A telescopic boom using a wire rope retractable lifting mechanism can strictly control the taking off and landing of hanging objects.

1.  Using a two-section telescopic cylinder design

one of the cylinders pushes the second large boom, another cylinder pushes the rest of the telescopic boom by the pulley block and wire rope；

To ensure the strong lifting capacity in the middle distance and effectively protect the wire rope in the boom.

2.  U-shaped arm

The lateral bending stiffness and torsional stiffness are better than other arm types;

The tensile stress of the upper half is larger, which improves the stability coefficient of the side plate;

The lower bottom plate is beneficial to improve the resistance to local instability. Ability;

Under the same force with the same cross-sectional area, the U-shaped section boom greatly improves its anti-deformation ability.

3.  Boom head adopted integral structure

Greater intensity(Spithead design reduces the boom head carrying capacity).
