Hammerhead Tower Crane:

Design: The hammerhead crane has a horizontal jib, and its tower is shaped like an 'A', with the tie-bars from the tip of the tower head (cat head) to the sections of the main jib to offer support. 

Functionality: The hammerhead crane is suitable for construction sites with limited space. Its design allows for easier slewing and better lifting capabilities in a confined area. Generally speaking hammerhead has higher lifting capacity as compared to other types of tower cranes at the same level of max. capacity. 

Flat Top Tower Crane:

Design: Unlike the hammerhead crane, a flat top crane does not have the cat head at the top of the tower. Instead, the jib and the tower head are at the same level, creating a flat appearance.

Functionality: Flat top cranes are versatile and can be used for various construction tasks. Their design allows for easier transportation and assembly on the construction site.

Luffing Jib Tower Crane:

Design: The luffing jib crane has a jib that can be raised and lowered independently of the tower. This allows the crane to operate in congested areas where a horizontal jib might be impractical.

Functionality: Luffing jib cranes are particularly useful in urban construction projects with limited space. They can lift heavy loads vertically and are known for their ability to work around obstacles.

Self-Erecting Tower Crane:

Design: A self-erecting crane is designed to be easily transported to a construction site and can be assembled without the need for an external crane. It typically comes on a wheeled chassis and has a telescoping mast.

Functionality: Self-erecting cranes are convenient for smaller construction projects or projects with a short duration. They offer the advantage of quick setup and dismantling, making them more mobile and efficient for certain applications.

 

The choice of which type of tower crane to use depends on the specific requirements of the construction project, such as the available space, lifting capacity, and the nature of the construction tasks involved. Each type of crane has its own advantages and limitations, and selecting the right one contributes to the overall efficiency and safety of the construction process.
