For large building construction projects, tower cranes are utilized rather often. These machinery are quite needed for heavy lifting as well as placing supplies and equipment. Tower cranes offer a different configuration that offers lots of benefits over more traditional cranes. These benefits comprise: quiet electrical operation, higher vertical lift, increased capacities, and reduced space requirements.
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 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 advantage in setup time and really saves time in equipment expenses too. Self-erecting cranes are often remote-controlled from the ground, even if there are some models that have an operator cab built onto the jib.
The self-erecting crane is usually freestanding to allow them the opportunity to be moved around. There are several 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 rotate freely without existing buildings blocking its movement. A luffing jib tower crane is great for such tight spaces. Most tower cranes have a fixed horizontal jib. The operator can raise or lower a luffing jib in order to allow the crane to swing in a reduced radius.
