For big building construction projects, tower cranes are utilized quite frequently. These equipments are quite required for heavy lifting as well as placing materials and equipment. Tower cranes offer a different configuration which provides many benefits 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 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 can travel along the length of the jib. The tower crane is capable of operating anywhere within the jib's radius.
Self-Erecting Tower Cranes
Self-erecting cranes are often assembled on location with the assistance of another crane. This greatly saves time in equipment expenses and provides a huge advantage in setup time as well. Self-erecting cranes are normally remote-controlled from the ground, although there are some models that 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 some models that have a telescoping tower which enables the crane to work at various heights without the need to reconfigure the tower.
Luffing Jib Tower Crane
Normally, 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 tight areas. Most tower cranes have a fixed horizontal jib. The driver is able to raise or lower a luffing jib in order to enable the crane to swing in a reduced radius.
