For huge building construction projects, tower cranes are utilized rather frequently. These machines are rather necessary for heavy lifting as well as positioning supplies and equipment. Tower cranes provide a different configuration which offers a lot of advantages over more traditional cranes. These advantages consist of: higher vertical lift, quiet electrical operation, increased capacities, and reduced space requirements.
Hammerhead Crane
The hammerhead crane is commonly 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 could travel 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 really saves time in equipment expenses and provides a huge benefit in setup time too. Self-erecting cranes are often remote-controlled from the ground, even if there are some models which have an operator cab built onto the jib.
Self-erecting cranes are usually freestanding and this allows them the opportunity to be able to be moved around. There are some models which have a telescoping tower that enables the crane to work at various 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 great for such confined areas. Nearly all tower cranes have a fixed horizontal jib. The driver can lower or raise a luffing jib in order to allow the crane to swing in a reduced radius.
