For huge building construction projects, tower cranes are used rather frequently. These equipments are quite needed for heavy lifting as well as positioning materials and equipment. Tower cranes provide a different design that provides numerous advantages over more traditional cranes. These benefits include: quiet electrical operation, higher vertical lift, increased capacities, and reduced space requirements.
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 acts as a counterweight and the other end of the jib extends horizontally over the worksite. On the hammerhead crane, there is a trolley. This trolley holds the lifting cable and could travel 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 normally assembled on site with the help of another crane. This provides a huge benefit in setup time and greatly saves time in equipment costs too. Self-erecting cranes are normally remote-controlled from the ground, even if there are some models that have an operator cab built onto the jib.
Self-erecting cranes are generally freestanding and this enables them the opportunity to be able to be moved around. There are some models which have a telescoping tower that enables the crane to work at various 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 rotate freely without being blocked by existing buildings. A luffing jib tower crane is ideal for such tight areas. Nearly all 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.
