For big building construction projects, tower cranes are utilized rather frequently. These equipments are rather required for heavy lifting as well as positioning supplies and equipment. Tower cranes offer a unique design which offers a lot of advantages over more conventional cranes. These advantages include: quiet electrical operation, higher vertical lift, 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 extends horizontally over the worksite and the other end of the jib acts as a counterweight. 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 in the jib's radius.
Self-Erecting Tower Cranes
Self-erecting cranes are often assembled on location with the help of another crane. This greatly 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 several models which have an operator cab built onto the jib.
Self-erecting cranes are normally freestanding and this allows them the opportunity to be able 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
The majority of urban work settings do not have enough space or clearance for the jib to rotate freely without existing buildings blocking its movement. A luffing jib tower crane is great for such tight spaces. Nearly all tower cranes have a fixed horizontal jib. The operator can raise or lower a luffing jib in order to enable the crane to swing in a reduced radius.
