For huge building construction projects, tower cranes are utilized rather frequently. These machinery are quite required for heavy lifting as well as placing materials and equipment. Tower cranes provide a unique configuration that provides a lot of benefits over more conventional 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 connected to a vertical tower, in this case. 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 has the lifting cable and travels 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 usually assembled on site with the assistance of a different crane. This greatly saves time in equipment expenses and provides a huge advantage in setup time too. Self-erecting cranes are usually remote-controlled from the ground, even though there are several models that have an operator cab built onto the jib.
Self-erecting cranes are normally freestanding and this enables 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 multiple heights without the need to reconfigure the tower.
Luffing Jib Tower Crane
Most urban work settings 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 great for such confined spaces. Most tower cranes have a fixed horizontal jib. The operator could lower or raise a luffing jib in order to enable the crane to swing in a reduced radius.
