For huge building construction projects, tower cranes are utilized rather often. These equipments are quite necessary for heavy lifting as well as placing supplies and equipment. Tower cranes provide a unique design which offers many benefits over more conventional cranes. These benefits consist of: 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 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 could travel along the length of the jib. The tower crane is capable of operating 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 assistance from another crane. This provides a huge advantage in setup time and greatly saves time in equipment expenses too. Self-erecting cranes are often remote-controlled from the ground, although there are several models which have an operator cab built onto the jib.
The self-erecting crane is generally freestanding to enable them the opportunity to be moved around. There are some models which have a telescoping tower that allows the crane to work at multiple heights without the need to reconfigure the tower.
Luffing Jib Tower Crane
Usually, in 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. Most tower cranes have a fixed horizontal jib. The driver is able to raise or lower a luffing jib in order to enable the crane to swing in a reduced radius.
