Advantages and Features
Technical Parameters

Stable Operation:


Reasonable Structure: The DH5612-6 tower crane adopts a scientific structure design. The connections of the main components such as the tower and boom are reliable and strong, which enables it to withstand heavy working loads and complex working conditions. This ensures that there will be no structural problems during construction, ensuring the smooth running of the construction work.


Reliable Electrical System: The electrical control system features stable operation, high control precision for actions such as hoisting, slewing and luffing. It can work stably in various environmental conditions, reducing the downtime due to electrical faults and improving the working efficiency of the crane.


Strong Load Capacity:


Large Maximum Lifting Weight: The maximum lifting weight of this type of tower crane generally reaches 6 tons, which meets the needs of lifting heavy building elements and materials in most construction projects. This greatly improves the construction efficiency.


Large Working Radius: Its working radius is large enough to cover a large construction site, reducing the number of crane movements. This reduces the labor intensity of construction site planning and costs.


High safety:


A complete set of safety devices: Equipped with a series of advanced safety devices such as overload limiter, torque limiter, height limiter, slewing limiter, etc. These safety devices can monitor the working status of the crane in real time and immediately give an alarm signal and take appropriate braking measures when abnormal situations occur, ensuring the safe operation of the crane.


High strength steel structure: The steel structure such as the tower and boom are made of high-strength steel and have undergone strict quality and strength tests. They have high strength and toughness, can withstand large external impacts, and provide reliable protection for the safe operation of the crane.


Easy to operate:


Ergonomic operator cabin: The operator cabin has a reasonable layout, simple and clear control interface. The operator can conveniently control various operations of the crane. In addition, the cabin is equipped with comfortable seats and good ventilation and lighting facilities, which creates a good working environment for the operator, reduces operator fatigue, and improves the accuracy and efficiency of control.


Convenient maintenance: The crane components are easy to dismantle and install, making daily maintenance easier. At the same time, Dahan's service system is perfect, and it can provide professional technical support and repair services in a timely manner, ensuring the normal operation of the crane.


Strong adaptability:


Suitable for various working conditions: No matter the construction of high-rise buildings in cities, bridge construction or industrial building construction, the DH5612-6 tower crane shows good adaptability and can meet the needs of various construction projects.


Suitable for various environments: It can work normally in various harsh environmental conditions, such as high temperature, low temperature, humidity, sandstorm, etc.
