For large building construction projects, tower cranes are used rather frequently. These machines are rather essential for heavy lifting as well as positioning materials and equipment. Tower cranes provide a different configuration that offers lots of advantages over more traditional cranes. These advantages comprise: quiet electrical operation, higher vertical lift, reduced space requirements and increased capacities.
Hammerhead Crane
The hammerhead crane is commonly associated with a tower crane. The long horizontal jib is connected 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 has 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 usually assembled on location with the help of a different crane. This provides a huge benefit in setup time and really saves time in equipment expenses too. Self-erecting cranes are usually remote-controlled from the ground, although there are some models which have an operator cab built onto the jib.
The self-erecting crane is normally freestanding to allow them the opportunity 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
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. The majority of tower cranes have a fixed horizontal jib. The operator is able to lower or raise a luffing jib in order to allow the crane to swing in a reduced radius.
