Tower cranes are being used regularly for huge building construction projects. They are required for the heavy lifting and positioning of materials and equipment. Tower cranes offer a different configuration that offers numerous 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 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. 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 could operate anywhere in the jib's radius.
Self-Erecting Tower Cranes
Self-erecting cranes are usually assembled on location with the help of a different crane. This provides a huge advantage in setup time and really saves time in equipment costs 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 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 enables the crane to work at various heights without the need to reconfigure the tower.
Luffing Jib Tower Crane
Normally, in 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 could lower or raise a luffing jib in order to allow the crane to swing in a reduced radius.
