Tower cranes are being utilized often for large building construction projects. They are needed for the heavy lifting and placing of materials and equipment. Tower cranes provide a different design that provides a lot of benefits over more traditional cranes. These advantages include: higher vertical lift, quiet electrical operation, reduced space requirements and increased capacities.
Hammerhead Crane
The hammerhead crane is commonly 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. There is a trolley on the hammerhead crane. This trolley holds the lifting cable and could travel along the length of the jib. The tower crane can operate anywhere within the jib's radius.
Self-Erecting Tower Cranes
Self-erecting cranes are often assembled on site with the help of a different crane. This greatly saves time in equipment expenses and provides a huge benefit in setup time too. Self-erecting cranes are normally remote-controlled from the ground, although there are several models which have an operator cab built onto the jib.
Self-erecting cranes are normally freestanding and this enables them the opportunity to be able to be moved around. There are some models that have a telescoping tower that enables the crane to work at various 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 great for such tight areas. The majority of tower cranes have a fixed horizontal jib. The operator can raise or lower a luffing jib in order to enable the crane to swing in a reduced radius.
