Tower cranes are being utilized regularly for huge building construction projects. They are needed for the heavy lifting and placing of materials and machinery. Tower cranes offer a different design that provides a lot of advantages over more conventional cranes. These benefits include: quiet electrical operation, higher vertical lift, reduced space requirements and increased capacities.
Hammerhead Crane
The hammerhead crane is frequently 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. On the hammerhead crane, there is a trolley. This trolley holds the lifting cable and can travel along the length of the jib. The tower crane is capable of operating anywhere in 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 really saves time in equipment expenses and provides a huge advantage in setup time too. Self-erecting cranes are normally remote-controlled from the ground, although there are some models which have an operator cab built onto the jib.
Self-erecting cranes are usually freestanding and this enables them the opportunity to be able to be moved around. There are some models that have a telescoping tower that enables the crane to work at various heights without the need to reconfigure the tower.
Luffing Jib Tower Crane
Often, within urban work environments, there is not enough space or clearance for the jib to rotate freely without being blocked by existing buildings. A luffing jib tower crane is ideal for such confined spaces. Nearly all tower cranes have a fixed horizontal jib. The operator can lower or raise a luffing jib in order to allow the crane to swing in a reduced radius.
