Tower cranes are being used often for large building construction projects. They are essential for the heavy lifting and placing of supplies and equipment. Tower cranes provide a unique design that provides lots of benefits over more conventional cranes. These benefits comprise: 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 connected 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. There is a trolley on the hammerhead crane. This trolley has the lifting cable and could travel along the length of the jib. The tower crane can operate anywhere within the jib's radius.
Self-Erecting Tower Cranes
Self-erecting cranes are normally assembled on site with the assistance of another crane. This greatly 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, even though there are several models which 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 which have a telescoping tower which enables the crane to work at various heights without the need to reconfigure the tower.
Luffing Jib Tower Crane
The majority of 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 tight spaces. The majority of tower cranes have a fixed horizontal jib. The driver could raise or lower a luffing jib in order to enable the crane to swing in a reduced radius.
