Tower cranes are being utilized frequently for large building construction projects. They are needed for the heavy lifting and positioning of materials and machines. Tower cranes offer a unique configuration which offers a lot of benefits over more traditional cranes. These advantages consist of: quiet electrical operation, higher vertical lift, 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 extends horizontally over the worksite and the other end of the jib acts as a counterweight. On the hammerhead crane, there is a trolley. 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 another crane. This really saves time in equipment expenses and provides a huge benefit in setup time as well. Self-erecting cranes are normally remote-controlled from the ground, though there are some models that have an operator cab built onto the jib.
The self-erecting crane is normally freestanding to allow them the opportunity to be moved around. There are some models that have a telescoping tower which enables the crane to work at various heights without the need to reconfigure the tower.
Luffing Jib Tower Crane
The majority of urban work environments 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 confined areas. Most tower cranes have a fixed horizontal jib. The operator could lower or raise a luffing jib in order to enable the crane to swing in a reduced radius.
