Tower cranes are being utilized regularly for big building construction projects. They are necessary for the heavy lifting and positioning of materials and machines. Tower cranes offer a different design that provides many advantages over more conventional cranes. These benefits consist of: higher vertical lift, quiet electrical operation, reduced space requirements and increased capacities.
Hammerhead Crane
The hammerhead crane is usually 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. 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 normally assembled on site with the assistance of another crane. This provides a huge advantage in setup time and really saves time in equipment costs as well. Self-erecting cranes are usually remote-controlled from the ground, even though there are several models which have an operator cab built onto the jib.
Self-erecting cranes are generally freestanding and this allows them the opportunity to be able to be moved around. There are some models that have a telescoping tower that allows the crane to work at various heights without the need to reconfigure the tower.
Luffing Jib Tower Crane
Often, within 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. The majority of tower cranes have a fixed horizontal jib. The driver is able to lower or raise a luffing jib in order to allow the crane to swing in a reduced radius.
