The LXD-type multi-point suspension crane is a specialized suspended crane designed specifically to meet the requirements of large-span industrial plants or warehouses such as aircraft manufacturing factories and aircraft maintenance workshops. This suspended crane can reduce the impact of the crane's weight on the roof structure of the building, helping to lower the overall building height and save significant construction costs for the facility.
The LXD multi-point suspension crane is driven by gear reduction motors for stable and reliable operation. The wear-resistant engineering plastic travel wheels effectively prevent wear against crane rails. Equipped with variable frequency speed regulation system, its wide speed range ensures higher positioning accuracy. The PLC control system enables synchronized operation of multiple cranes, significantly expanding working range. With a working class up to A5, it is particularly suitable for intensive applications in aircraft manufacturing plants and large maintenance workshops with wide-span requirements.
The LXD type multi-point suspension crane is suitable for material handling in large workshops or long-span production lines. It is installed beneath the workshop roof structure and distributes the load evenly through multiple suspension points. It is especially applicable in areas spanning multiple workstations or where floor rail installation is not feasible.

Its products are exported to over 100 countries and regions, including the United States, Russia, and Southeast Asia.
Annually, Dafang manufactures 30,000 single-girder cranes, more than 12,000 double-girder and gantry cranes, and 30,000 electric hoists. Based on production scale, sales volume, and brand recognition, the company ranks among the top three in China’s crane industry.
2. Core Technologies
Dafang’s R&D team consists of over 260 members, including 104 with senior or intermediate engineering qualifications. The company invests 3.8% of its annual sales into technology development. It has obtained 12 international invention patents, 50 national invention patents, 415 utility model patents, and achieved 43 scientific and technological milestones. Dafang was the first in the industry to adopt anti-sway and automatic positioning technologies.
In 2016, Dafang became the first enterprise in Henan Province to implement smart crane applications and to introduce remote monitoring technology. The company also developed the multifunctional brewing crane, filling a domestic market gap. In 2021, Dafang was the first in the industry to be certified for unmanned intelligent cranes. In 2022, it undertook a project for a tower crane at a commercial satellite launch site.
3. Manufacturing Capability
Dafang Heavy Machinery is equipped with advanced in-house designed manufacturing equipment, including 1,500-ton press grooving machines, extrusion machines, and roller machines. The company has established leading domestic workshops, including an electrical assembly line, steel pre-processing line, paint finishing line, and China’s first practical single-girder lean production line. Precision machinery includes imported German NILES CNC gear grinding machines and Japanese MAZAK machining centers.
Dafang strictly follows refined manufacturing processes, adhering to the principle of “doing it right the first time, zero defects.” This commitment to quality is deeply ingrained in every employee, ensuring that every product delivered meets the highest standards.

It is suitable for workshops with strong roof structures, large spans, or where floor rails are difficult to install, commonly used in assembly shops and automotive production lines.
The roof beams must have sufficient load-bearing capacity and allow for the layout of multiple suspension points. Structural strength assessment is required before installation.
The standard lifting capacity can reach 20 tons, and the span can be customized to over 35 meters. Specific parameters can be designed according to user needs.
Yes. It can be equipped with a PLC control system to achieve synchronized lifting at multiple suspension points, ensuring stable operation and preventing equipment distortion or unbalanced loads.
It has a simple structure and is easy to maintain. Regular inspection of suspension points, rail systems, and electrical circuits is required to ensure even load distribution and prevent abnormal wear.
