Tower cranes are being utilized regularly for big building construction projects. They are essential for the heavy lifting and placing of supplies and machinery. Tower cranes offer a unique configuration that offers numerous advantages over more conventional cranes. These benefits consist of: 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 attached to a vertical tower, in this case. 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 travels along the length of the jib. The tower crane could operate 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 help from a secondary crane. This greatly saves time in equipment expenses and provides a huge advantage in setup time as well. Self-erecting cranes are normally remote-controlled from the ground, though there are some models which have an operator cab built onto the jib.
Self-erecting cranes are normally freestanding and this allows them the opportunity to be able to be moved around. There are some models which have a telescoping tower that allows the crane to work at multiple heights without the need to reconfigure the tower.
Luffing Jib Tower Crane
Most urban work environments do not have enough space or clearance for the jib to rotate freely without existing buildings blocking its movement. A luffing jib tower crane is ideal for such tight spaces. Nearly all tower cranes have a fixed horizontal jib. The driver can lower or raise a luffing jib in order to enable the crane to swing in a reduced radius.
