What is the difference between a crane and a tower crane?

There are obvious differences between cranes and tower cranes in terms of structure, usage scenarios, and operation methods. Let's take a closer look.

1. Definition of cranes and tower cranes
A crane is a mobile lifting machinery, usually composed of a chassis, a lifting mechanism, legs, and a cab. The main function of a crane is to load, unload, and transport goods at a construction site or on site. Therefore, a crane is also called a mobile crane.
A tower crane is a static lifting machinery, usually composed of a main tower, a lifting mechanism, and a control device. A tower crane is usually supported and fixed at a construction site by a special fixed bracket, and is mainly used for lifting and transporting heavy objects in high-altitude construction.

2. The structures of cranes and tower cranes are different
The structure of a crane is relatively simple, its legs can be folded and reduced, and it is easy to carry, which is suitable for cargo handling, loading and unloading, and construction on the ground.
The structure of a tower crane is relatively complex, mainly composed of a tower crane, a balance arm, and a hook. Tower cranes often need to work in high-altitude construction scenes and need to be fixed at a specific location to ensure safety and stability.

3. The use scenarios of cranes and tower cranes are different
Crane is suitable for moving goods at civil and industrial construction sites and other places, such as loading and unloading goods on vehicles and building bridges, large buildings, etc.
Tower cranes are mainly used in construction sites such as high-rise buildings, bridge projects, and transportation construction. Their construction scenes are usually high-altitude and narrow, and they need to give full play to their high-quality and efficient operation characteristics.

4. The use methods of cranes and tower cranes are different
During use, the crane needs to be operated by a full-time driver, and its center of gravity is relatively low, so it is easier to move and operate the lifting objects.
Tower cranes need to be remotely controlled by professional operators or operated in the cab of the head. Because of its complex structure, its operation technology requirements are relatively high.

5. Development trend of cranes and tower cranes
With the continuous development of science and technology, modern lifting machinery is constantly emerging, and more and more models are not only unique in structure and diversified in function, but also have the characteristics of autonomy and intelligence. In the future, both cranes and tower cranes will usher in new changes and will become a powerful assistant for humans in the fields of construction and heavy industry.

In general, both are lifting machinery, but each has its own advantages and limitations. In actual applications, choosing different types of lifting machinery according to construction scenarios and needs can better improve work efficiency and safety.
