Tower cranes are being used regularly for large building construction projects. They are essential for the heavy lifting and positioning of materials and machinery. Tower cranes offer a unique design that offers lots of advantages over more conventional cranes. These advantages comprise: higher vertical lift, quiet electrical operation, reduced space requirements and increased capacities.
Hammerhead Crane
The hammerhead crane is commonly associated with a tower crane. The long horizontal jib is attached to a vertical tower, in this situation. One end of the jib extends horizontally over the worksite and the other end of the jib acts as a counterweight. 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 could operate anywhere within the jib's radius.
Self-Erecting Tower Cranes
A self-erecting crane is capable of completely assembling itself at the jobsite without any help from a secondary crane. This really saves time in equipment expenses and provides a huge benefit in setup time too. Self-erecting cranes are usually remote-controlled from the ground, though there are some models that have an operator cab built onto the jib.
The self-erecting crane is normally freestanding to allow them the opportunity to be moved around. There are several models which have a telescoping tower which allows the crane to work at multiple heights without the need to reconfigure the tower.
Luffing Jib Tower Crane
Usually, within urban work settings, there is not enough space or clearance for the jib to rotate freely without being blocked by existing buildings. A luffing jib tower crane is great for such confined spaces. The majority of tower cranes have a fixed horizontal jib. The driver can raise or lower a luffing jib in order to allow the crane to swing in a reduced radius.
