For large building construction projects, tower cranes are utilized rather often. These equipments are quite essential for heavy lifting as well as placing materials and equipment. Tower cranes offer a unique configuration which offers many benefits over more traditional cranes. These benefits include: quiet electrical operation, higher vertical lift, increased capacities, and reduced space requirements.
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 extends horizontally over the worksite and the other end of the jib acts as a counterweight. On the hammerhead crane, there is a trolley. This trolley has 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
Self-erecting cranes are usually assembled on site with the help of a different crane. This really 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, although 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 several models which have a telescoping tower that enables the crane to work at multiple heights without the need to reconfigure the tower.
Luffing Jib Tower Crane
Most urban work settings do not have enough space or clearance for the jib to freely rotate 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 is able to raise or lower a luffing jib in order to allow the crane to swing in a reduced radius.
