Tower cranes are being used frequently for huge building construction projects. They are essential for the heavy lifting and positioning of materials and machinery. Tower cranes provide a unique configuration which provides lots of advantages over more traditional cranes. These advantages comprise: 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 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. 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 is capable of operating anywhere in the jib's radius.
Self-Erecting Tower Cranes
Self-erecting cranes are often assembled on site with the assistance of a different crane. This really saves time in equipment costs and provides a huge advantage in setup time as well. Self-erecting cranes are often remote-controlled from the ground, although there are some 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 enables the crane to work at various heights without the need to reconfigure the tower.
Luffing Jib Tower Crane
Most urban work environments do not have enough clearance or space for the jib to freely rotate without existing buildings blocking its movement. A luffing jib tower crane is ideal for such tight spaces. The majority of tower cranes have a fixed horizontal jib. The driver could lower or raise a luffing jib in order to enable the crane to swing in a reduced radius.
