For big building construction projects, tower cranes are used quite frequently. These machinery are rather essential for heavy lifting as well as positioning materials and equipment. Tower cranes offer a different design which provides 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 frequently 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 can travel along the length of the jib. The tower crane is capable of operating anywhere within the jib's radius.
Self-Erecting Tower Cranes
A self-erecting crane is capable of completely assembling itself at the jobsite without any help from another crane. This really saves time in equipment costs and provides a huge benefit in setup time too. Self-erecting cranes are usually remote-controlled from the ground, although there are several models which have an operator cab built onto the jib.
The self-erecting crane is generally 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
Nearly all urban work environments do not have enough space or clearance for the jib to rotate freely without existing buildings blocking its movement. A luffing jib tower crane is great for such confined areas. Most tower cranes have a fixed horizontal jib. The operator is able to raise or lower a luffing jib in order to allow the crane to swing in a reduced radius.
