For huge building construction projects, tower cranes are used rather frequently. These equipments are rather necessary for heavy lifting as well as positioning supplies and equipment. Tower cranes provide a unique configuration that provides a lot of benefits over more traditional cranes. These advantages comprise: quiet electrical operation, higher vertical lift, reduced space requirements and increased capacities.
Hammerhead Crane
The hammerhead crane is usually associated with a tower crane. The long horizontal jib is attached 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. On the hammerhead crane, there is a trolley. This trolley holds the lifting cable and travels along the length of the jib. The tower crane is capable of operating anywhere within the jib's radius.
Self-Erecting Tower Cranes
Self-erecting cranes are usually assembled on location with the assistance of a different 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 several models that have an operator cab built onto the jib.
The self-erecting crane is normally freestanding to enable them the opportunity to be moved around. There are some 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
Normally, in urban work settings, there is not enough space or clearance for the jib to freely rotate without being blocked by existing buildings. A luffing jib tower crane is great for such confined spaces. Nearly all tower cranes have a fixed horizontal jib. The driver could lower or raise a luffing jib in order to enable the crane to swing in a reduced radius.
