For huge building construction projects, tower cranes are utilized quite often. These equipments are rather needed for heavy lifting as well as placing materials and equipment. Tower cranes offer a different design which offers lots of benefits over more traditional cranes. These advantages consist of: quiet electrical operation, higher vertical lift, increased capacities, and reduced space requirements.
Hammerhead Crane
The hammerhead crane is frequently associated with a tower crane. The long horizontal jib is attached to a vertical tower, in this situation. One end of the jib acts as a counterweight and the other end of the jib extends horizontally over the worksite. 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 costs too. Self-erecting cranes are usually remote-controlled from the ground, though there are several 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 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 environments 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 ideal for such confined spaces. Nearly all tower cranes have a fixed horizontal jib. The driver is able to lower or raise a luffing jib in order to enable the crane to swing in a reduced radius.
