For big building construction projects, tower cranes are utilized quite often. These machinery are quite essential for heavy lifting as well as placing materials and equipment. Tower cranes offer a different configuration that provides many advantages over more conventional cranes. These advantages consist of: 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 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. 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 can operate anywhere in the jib's radius.
Self-Erecting Tower Cranes
Self-erecting cranes are often assembled on location with the assistance of a different crane. This greatly saves time in equipment expenses and provides a huge advantage in setup time too. Self-erecting cranes are usually remote-controlled from the ground, though there are several models which have an operator cab built onto the jib.
The self-erecting crane is usually freestanding to enable them the opportunity to be moved around. There are several 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
Nearly all urban work settings do not have enough clearance or space 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 operator can raise or lower a luffing jib in order to enable the crane to swing in a reduced radius.
