For big building construction projects, tower cranes are used quite often. These equipments are quite necessary for heavy lifting as well as placing supplies and equipment. Tower cranes provide a different configuration that offers numerous benefits over more traditional cranes. These benefits comprise: quiet electrical operation, higher vertical lift, reduced space requirements and increased capacities.
Hammerhead Crane
A hammerhead crane is another design which is most typically associated with a tower crane. In this situation, a long horizontal jib is attached to a vertical tower. 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 is capable of operating anywhere within the jib's radius.
Self-Erecting Tower Cranes
Self-erecting cranes are normally assembled on location with the assistance of a different crane. This really saves time in equipment expenses and provides a huge advantage in setup time as well. 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 generally freestanding to enable them the opportunity to be moved around. There are several models which have a telescoping tower that enables the crane to work at multiple heights without the need to reconfigure the tower.
Luffing Jib Tower Crane
Most urban work settings do not have enough space or clearance 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.
