Product Overview and Product Advantages

Product Overview
Tower cranes are mainly composed of three major parts: the metal structure, the working mechanism, and the electrical system. The metal structure serves as the framework of the entire machine and includes components such as the base frame, tower body, turntable, tower cap, lifting arm, and balancing arm; the working mechanism is the core for performing lifting operations, covering four major mechanisms: lifting, slewing, rotation, and traveling; the electrical system is responsible for the power transmission and intelligent control of the entire machine.
Product Overview
In terms of lifting height, tower cranes can reach over 100 meters with the help of the vertical tower body and the top lifting mechanism; for super high-rise buildings, the internal climbing tower crane can climb along with the construction progress, reaching an operation height of several hundred meters. In terms of the working range, tower cranes can conveniently approach buildings and, through the slewing and rotation of the lifting arm, form a large continuous operation area, greatly improving construction efficiency. In recent years, tower cranes are rapidly evolving in the direction of precise design, modular components, intelligent control, and green manufacturing, with overall performance and safety significantly improved.

Product Advantages
Large lifting height and high amplitude utilization: The tower crane can meet various height requirements by adding standard sections or attaching to buildings. Its vertical tower body combined with the top lifting arm allows close proximity to buildings, maximizing amplitude utilization.
Wide operation range and high efficiency: The crane covers a broad working area around the tower body. Mobile tower cranes can move with loads along tracks, creating a continuous work zone that greatly enhances efficiency.
Light structure with high load capacity: Modern cranes use high-strength cold-formed steel and bolts, reducing boom weight and foundation load while improving lifting performance and wind resistance.
Precise control and intelligence: Equipped with a full variable frequency control system and worm gear speed control, the crane achieves flexible operation and millimeter-level positioning accuracy.
Applicable venue

Real estate and construction sector: Suitable for the hoisting of steel bars, formworks and prefabricated components for high-rise and super-high-rise residential buildings and commercial complexes.
Infrastructure and venue construction: In projects such as bridges, large sports venues, and airports, it is used for the precise assembly of large-span and heavy-duty steel structures.
Energy and power engineering: In thermal power, hydropower and wind power projects, it is used for the ultra-high and ultra-heavy hoisting of boiler steam drums, stators and large fan blades.
