Tower cranes are being utilized regularly for big building construction projects. They are necessary for the heavy lifting and positioning of supplies and machinery. Tower cranes offer a unique configuration that provides many advantages over more traditional cranes. These advantages consist of: quiet electrical operation, higher vertical lift, 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 case. 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 can operate anywhere in 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 costs too. Self-erecting cranes are often remote-controlled from the ground, even if there are some models which have an operator cab built onto the jib.
Self-erecting cranes are usually freestanding and this allows them the opportunity to be able to be moved around. There are several 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 ideal for such confined areas. Most tower cranes have a fixed horizontal jib. The operator can lower or raise a luffing jib in order to enable the crane to swing in a reduced radius.
