For huge building construction projects, tower cranes are utilized quite frequently. These equipments are quite necessary for heavy lifting as well as placing supplies and equipment. Tower cranes provide a different design which offers lots of benefits over more conventional cranes. These advantages include: higher vertical lift, quiet electrical operation, reduced space requirements and increased capacities.
Hammerhead Crane
The hammerhead crane is frequently 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 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 help from another crane. This really saves time in equipment expenses and provides a huge benefit in setup time as well. Self-erecting cranes are normally remote-controlled from the ground, even though there are several models that have an operator cab built onto the jib.
Self-erecting cranes are normally freestanding and this allows them the opportunity to be able 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
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. Most tower cranes have a fixed horizontal jib. The driver is able to lower or raise a luffing jib in order to enable the crane to swing in a reduced radius.
