Tower cranes are being utilized often for big building construction projects. They are necessary for the heavy lifting and positioning of materials and machines. Tower cranes offer a different configuration which provides many benefits over more conventional cranes. These advantages consist of: quiet electrical operation, higher vertical lift, reduced space requirements and increased capacities.
Hammerhead Crane
The hammerhead crane is usually associated with a tower crane. The long horizontal jib is attached 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 holds the lifting cable and travels 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 provides a huge advantage in setup time and greatly saves time in equipment expenses too. Self-erecting cranes are usually remote-controlled from the ground, even if there are several models that 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 that have a telescoping tower that allows the crane to work at multiple heights without the need to reconfigure the tower.
Luffing Jib Tower Crane
The majority of 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 great for such tight areas. Most tower cranes have a fixed horizontal jib. The driver is able to lower or raise a luffing jib in order to allow the crane to swing in a reduced radius.
