Tower cranes are being used frequently for huge building construction projects. They are essential for the heavy lifting and placing of materials and machinery. Tower cranes offer a different configuration that offers many benefits over more traditional cranes. These benefits comprise: higher vertical lift, quiet electrical operation, increased capacities, and reduced space requirements.
Hammerhead Crane
The hammerhead crane is usually associated with a tower crane. The long horizontal jib is connected to a vertical tower, in this situation. One end of the jib acts as a counterweight and the other end of the jib extends horizontally over the worksite. There is a trolley on the hammerhead crane. This trolley has the lifting cable and could travel along the length of the jib. The tower crane is capable of operating anywhere within the jib's radius.
Self-Erecting Tower Cranes
A self-erecting crane is capable of completely assembling itself at the jobsite without any assistance from a secondary crane. This provides a huge advantage in setup time and greatly saves time in equipment costs too. Self-erecting cranes are normally remote-controlled from the ground, though there are several models that have an operator cab built onto the jib.
Self-erecting cranes are generally freestanding and this enables them the opportunity to be able to be moved around. There are several models that have a telescoping tower which allows the crane to work at various heights without the need to reconfigure the tower.
Luffing Jib Tower Crane
The majority of urban work settings do not have enough clearance or space for the jib to freely rotate without existing buildings blocking its movement. A luffing jib tower crane is great for such tight areas. Nearly all tower cranes have a fixed horizontal jib. The operator can lower or raise a luffing jib in order to enable the crane to swing in a reduced radius.
