For huge building construction projects, tower cranes are utilized rather often. These equipments are quite necessary for heavy lifting as well as placing materials and equipment. Tower cranes offer a unique design which offers many benefits over more traditional cranes. These benefits comprise: higher vertical lift, quiet electrical operation, 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 case. 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
Self-erecting cranes are usually assembled on location with the assistance of another crane. This provides a huge benefit in setup time and greatly saves time in equipment expenses too. Self-erecting cranes are normally remote-controlled from the ground, although there are some models that have an operator cab built onto the jib.
The self-erecting crane is generally freestanding to allow them the opportunity to be moved around. There are several models that have a telescoping tower that 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 rotate freely without existing buildings blocking its movement. A luffing jib tower crane is ideal for such tight spaces. Nearly all tower cranes have a fixed horizontal jib. The driver can lower or raise a luffing jib in order to enable the crane to swing in a reduced radius.
