ZTT296 12ton Tower Crane Properties
1. Integrated cab and built-in ABB electric control cabinet which make topless tower crane with air conditioner has easy and intelligent operation, long service life, humanized design, and comfortable tower working environment.
2. Topless tower crane with air conditioner has diagonal ladder design, that is, every 3 meters a galvanized platform which is safer for climbing.
3. Low voltage full load operation
■ Even if the incoming voltage of frequency converter is lowered to 308V (usually 342V to meet the working requirements of frequency converter), it can ensure stable operation with a full load.
■ It can avoid the hidden danger of hoisting safety caused by voltage instability.

FAQ
What is the main use of a tower crane?
Tower cranes are mainly used in high-rise construction, especially when there is a need to vertically lift heavy loads or large components. They provide an efficient lifting solution on construction sites.
What is the working principle of a tower crane?
A tower crane operates with a rotating mast and jib. It lifts heavy objects using a hook powered by an electric motor, with steel cables that carry the load during lifting operations.
What are the main safety measures for tower cranes?
Safety measures for tower cranes include regular inspections and maintenance, operator training, overload prevention systems, and the installation of limit devices.
What is the lifting capacity of a tower crane?
The lifting capacity of a tower crane depends on the model and configuration, typically ranging from several tons to several hundred tons.
Are tower cranes suitable for all construction projects?
Tower cranes are primarily used for high-rise buildings and large-scale construction projects. They may not be suitable for low-rise buildings or smaller projects.
What is the typical rental cost for a tower crane?
The rental cost of a tower crane varies depending on the crane's specifications, rental duration, and location, typically ranging from several thousand to tens of thousands of RMB.
