Tower cranes are being utilized often for big building construction projects. They are needed for the heavy lifting and positioning of supplies and machinery. Tower cranes provide a unique configuration which provides many benefits over more conventional cranes. These advantages consist of: higher vertical lift, quiet electrical operation, 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 case. 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 has 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 location with the assistance of a different crane. This provides a huge benefit in setup time and greatly saves time in equipment costs too. Self-erecting cranes are normally remote-controlled from the ground, though 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 some models which have a telescoping tower which enables the crane to work at various heights without the need to reconfigure the tower.
Luffing Jib Tower Crane
Usually, within urban work settings, there is not enough clearance or space for the jib to rotate freely without being blocked by existing buildings. A luffing jib tower crane is great for such confined areas. The majority of tower cranes have a fixed horizontal jib. The driver can lower or raise a luffing jib in order to enable the crane to swing in a reduced radius.
