1. The flat head tower crane has a quick and convenient segmented installation of the lifting arm and balance arm, and can also change the arm in the air;
2. The standard section of the tower body adopts the L69 type sheet mounted structure design and is equipped with an inclined ladder;
3. The lifting arm can achieve multiple arm length combinations according to user requirements;
4. The lifting, slewing, and amplitude are all controlled by frequency conversion. The lifting mechanism has zero servo anti fall function, and the slewing mechanism has anti sway function.
The standard section is a piece assembly structure connected by a fishplate and a pin shaft, which is suitable for long-distance transportation; The climbing ladder is an inclined ladder, which is safe and convenient for climbing up and down tower cranes.
Design a rope supported trolley to reduce the sagging of the lifting wire rope and increase the passability of tower operations.
The crane arm is installed in sections, connected in the air, and designed with various installation brackets for quick and convenient installation.
The lifting mechanism is controlled by frequency conversion and adopts a large-diameter double fold groove drum for rope arrangement. It has closed-loop control, stepless speed regulation, smooth starting and braking, and zero servo function.
The small car amplitude mechanism adopts a variable frequency motor and variable frequency control, with a compact structure and accurate positioning.
