A tower crane is an important part of every construction site worldwide. Their towers, which look like they go on forever, can be seen hundreds of feet above the ground in almost every major city. These huge machines may save lives when working on a project requiring heavy lifting at great heights. However, buying a tower crane cost can be quite expensive. Because of this, contractors often look for tower cranes that are available to rent.
Tower cranes are the most beautiful buildings in cities and are also very useful for lifting steel, concrete, and other heavy materials. They also make it easier to move heavy equipment.
Tower Crane Components
In several ways, the parts that make up a tower crane are directly responsible for its work. Let’s look at the basic parts of a tower crane so we can get a better idea of what it can do.
- Base Support
Usually, the base support is attached to a concrete pad on the ground, which may be at the bottom of the tower. The base support could also be connected to a steel grillage or a ballasted chassis placed on the ground or top of an existing structure.
The tower, also called the mast, is the crane part that stands up straight and gives it its impressive height. This part of the structure goes from the ground up and supports parts like the cab, the hook, and the counterweights. Latticework made of steel is often put on towers to make them stronger.
The arm of the crane can turn because of a part called the “turntable.” This part is made with the same technology often found in windmills. Because of this, the jib can move in a wider range of ways.
- Cabin of Operator
The tower crane’s operator will sit in the cab while doing their work with the crane. It has compartments inside that hold the computer, joysticks, and control systems.
- Working Arm or Jib
The jib is the crane part that sticks out horizontally from the top of the tower. It is also called the working arm of the crane. This part will support and keep the weight in place while it is lifted.
- Block Trolley and Hook
The trolley is called the crane part that moves back and forth over the jib. The hook block has a pulley system that allows the hook to move up and down the tower.
- Counter Jib
With the help of the counter jib, which goes in the opposite direction of the jib, the tower crane is better able to keep its balance.
Counterweights keep the lift’s load from being too heavy or too light. If they weren’t there, the load limit would have to be cut down by a lot for the structure to stay stable. This important part is on the counter jib’s back, on the side that faces away from the jib. Counterweights are often made of steel or concrete that has been strengthened.
