For big building construction projects, tower cranes are used rather frequently. These equipments are quite necessary for heavy lifting as well as positioning supplies and equipment. Tower cranes offer a different configuration which offers a lot of advantages over more traditional cranes. These benefits comprise: 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 case. 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 in the jib's radius.
Self-Erecting Tower Cranes
Self-erecting cranes are often assembled on location with the assistance of another crane. This really saves time in equipment costs and provides a huge advantage in setup time as well. Self-erecting cranes are usually remote-controlled from the ground, although there are some models that have an operator cab built onto the jib.
Self-erecting cranes are usually freestanding and this enables them the opportunity to be able to be moved around. There are several models that have a telescoping tower that enables the crane to work at various heights without the need to reconfigure the tower.
Luffing Jib Tower Crane
Normally, in urban work settings, there is not enough space or clearance for the jib to freely rotate without being blocked by existing buildings. A luffing jib tower crane is ideal for such tight areas. The majority of tower cranes have a fixed horizontal jib. The operator could raise or lower a luffing jib in order to enable the crane to swing in a reduced radius.
