For huge building construction projects, tower cranes are utilized quite frequently. These equipments are rather essential for heavy lifting as well as positioning supplies and equipment. Tower cranes provide a different configuration that provides lots of advantages over more conventional cranes. These benefits consist of: 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. 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 could operate 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 assistance from a secondary crane. This really saves time in equipment expenses and provides a huge benefit in setup time as well. Self-erecting cranes are often remote-controlled from the ground, although there are several models which have an operator cab built onto the jib.
The self-erecting crane is normally freestanding to enable them the opportunity to be moved around. There are some models that have a telescoping tower that allows 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 clearance or space for the jib to freely rotate without existing buildings blocking its movement. A luffing jib tower crane is great for such confined spaces. The majority of tower cranes have a fixed horizontal jib. The driver could raise or lower a luffing jib in order to enable the crane to swing in a reduced radius.
