For big building construction projects, tower cranes are utilized quite often. These machines are rather necessary for heavy lifting as well as placing supplies and equipment. Tower cranes provide a different configuration which provides a lot of advantages over more traditional cranes. These benefits include: quiet electrical operation, higher vertical lift, reduced space requirements and increased capacities.
Hammerhead Crane
The hammerhead crane is frequently 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 travels along the length of the jib. The tower crane can operate anywhere in the jib's radius.
Self-Erecting Tower Cranes
A self-erecting crane is capable of completely assembling itself at the jobsite without any assistance from a secondary crane. This provides a huge advantage in setup time and really saves time in equipment costs too. Self-erecting cranes are often remote-controlled from the ground, though there are several models which 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 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 clearance or space for the jib to freely rotate without existing buildings blocking its movement. A luffing jib tower crane is great for such tight areas. The majority of tower cranes have a fixed horizontal jib. The operator could lower or raise a luffing jib in order to allow the crane to swing in a reduced radius.
