Latest company cases about Types of tower cranes

Tower cranes are divided into the following types:

Topkit Tower Crane

The typical for topkit tower crane is it with tower head and connet working jib and counter-jib by pull rods. The structure are stable.

The type of tower crane cost is cheaper than other types.

Hammerhead or Flat top Tower Crane

In the hammer head crane, a long horizontal jib is attached to a vertical tower. One end of the jib extends horizontally at the workplace, while the other end has balance weights.

This type of tower crane typically requires a second crane to assemble and disassemble parts at the workplace.

Self-erecting Tower Cranes

Self-erecting or self-assembling tower cranes can be assembled on site alone without the need for a second crane. This advantage will be very important in reducing launching time and project costs.

Self-erected tower cranes are often remotely controlled from the ground. These types of towers are usually independent and can be equipped to move around the workplace.

Luffing Jib Tower Crane

In tight urban spaces, there is usually not enough space to rotate the jib. Luffing jib tower cranes are used for such spaces. While most tower cranes have a fixed horizontal jib, the operator can raise or lower a luffing jib to allow the crane to be reduced in radius.

A luffing jib does not use an electric wagon, but raises and lowers the jib if needed for lifts closer to the tower. Due to the complexity of these types of cranes, luffing cranes are expensive and can only be used when absolutely needed.
