For huge building construction projects, tower cranes are utilized quite often. These machinery are rather necessary for heavy lifting as well as placing supplies and equipment. Tower cranes provide a different design which offers numerous advantages over more traditional cranes. These benefits consist of: quiet electrical operation, higher vertical lift, reduced space requirements and increased capacities.
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 holds the lifting cable and travels 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 often assembled on location with the assistance of a different crane. This provides a huge advantage in setup time and greatly saves time in equipment costs as well. Self-erecting cranes are often remote-controlled from the ground, even if there are several models that have an operator cab built onto the jib.
Self-erecting cranes are normally freestanding and this enables them the opportunity to be able to be moved around. There are some models that 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 confined spaces. Nearly all tower cranes have a fixed horizontal jib. The driver could raise or lower a luffing jib in order to enable the crane to swing in a reduced radius.
