Tower Head Crane
Tower cranes deliver irreplaceable lifting solutions for modern high-rise urban projects and complex constructions, with core competitive advantages in 3D spatial flexibility, millimeter-grade positioning, and intelligent safety systems.
Core Components & Functions
| Base | Concrete/steel foundation platform bearing full dynamic loads |
| Tower Mast | Primary load-bearing structure (standard/reinforced sections) |
| Climbing System | Hydraulic frame enabling self-climbing height adjustment |
| Slewing Unit | 360° horizontal rotation drive (slewing ring + geared motor) |
| Hoisting Unit | Main winch system for vertical load movement (±5mm VFD positioning) |
| Counter Jib | Counterweight blocks balancing load moments (balance ratio ≥1.4) |
| Main Jib | Truss/tubular load-bearing member (60-100m modular design) |
| Trolley | Sheave block assembly moving on jib rails (direct hook load carrier) |
| Tower Top | Triangular structure anchoring jib suspension ropes |
| Operator Cab | Panoramic control center (ISO 10218 ergonomic compliance) |
| Luffing System | Trolley traverse drive along jib (wire rope/rack-and-pinion transmission) |
The self-climbing process of a tower crane involves the following steps: First, the climbing sleeve is raised upward, creating a space between the main tower and the sleeve. A standard section is then installed within this space. The sleeve is subsequently lifted further, and another new standard section is installed beneath it. By continuously adding standard sections in this manner, the tower crane elevates itself.
The second-hand tower crane sold by our company is full of frequency conversion, stable and easy to use, and the installation time of the whole machine is shortened by 3 hours compared with the industry, the arm length is 60m~30m, 5m per variable arm, and 7 kinds of arm length combinations; The tower body is multi-matched, the independent height is high, and the attachment is overhanging. The reliability test of the whole machine exceeds 10,000 working cycles, and the key components are specially tested and verified, and the rope is not messy, and the wire rope has a long life; Panasonic PLC, reliable and durable. Hook top anti-falling device, invention patent, TSM tower crane safety monitoring system, full monitoring of lifting capacity, torque, etc.
Advantages of tower cranes
Superior lifting performance: the use of full frequency conversion speed regulation technology, smooth operation, high operation efficiency, reduce impact, improve the service life of the wire rope. The capacity of the wire rope reaches 610m, which meets the height needs of high-rise construction at home and abroad. The lifting and luffing rope rows are neat, which further improves the service life of the wire rope.
Diversified configuration: The tower body has a variety of size options, such as 1.8m× 1.8m× 2.8m and 1.6m×1.6m×3.0m, to adapt to different construction needs. The boom length is varied, including 65m, 60m, 55m, 50m, 45m, 40m, 35m, etc., providing flexible use scenarios.
Advanced electrical control system: PLC control is adopted to improve the reliability and safety of the system. The key electrical components adopt international well-known brands to ensure the stability and durability of the equipment.
The driver's cab design is user-friendly: the driver's cab is spacious, comfortable, and has a wide field of vision, providing a good working environment. The open climbing frame design allows multiple machines to share a single climbing frame, saving costs.
Stability and reliability: Frequency conversion control is used for rotation and luffing, which makes the tower crane run more smoothly. The design of the electronic control system improves the overall stability and reliability.
Applicable Scenarios
High-rise building construction: suitable for material hoisting of super high-rise residential, commercial buildings and other projects.
Bridge construction: It can easily cope with the hoisting needs of large bridge components.
Industrial installation: suitable for the installation of large industrial equipment such as power plants and chemical plants.
Port terminal: It can be used for loading and unloading containers and heavy equipment.
