For big building construction projects, tower cranes are utilized quite often. These machinery are rather necessary for heavy lifting as well as positioning materials and equipment. Tower cranes provide a different configuration that provides numerous advantages over more traditional cranes. These advantages include: higher vertical lift, quiet electrical operation, increased capacities, and reduced space requirements.
Hammerhead Crane
The hammerhead crane is frequently associated with a tower crane. The long horizontal jib is attached 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 holds the lifting cable and could travel 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 usually assembled on site with the help of a different crane. This really saves time in equipment costs and provides a huge advantage in setup time too. Self-erecting cranes are normally remote-controlled from the ground, even though there are some models that have an operator cab built onto the jib.
The self-erecting crane is generally freestanding to allow them the opportunity to be moved around. There are some models that have a telescoping tower that enables the crane to work at multiple heights without the need to reconfigure the tower.
Luffing Jib Tower Crane
Usually, in urban work settings, there is not enough clearance or space for the jib to rotate freely without being blocked by existing buildings. A luffing jib tower crane is great for such confined areas. Most tower cranes have a fixed horizontal jib. The operator could lower or raise a luffing jib in order to allow the crane to swing in a reduced radius.
