How do Cranes Lift and Move Heavy Load in a Project Site?

May 24, 2021

One of the most prominent industries today that carry out dangerous activities is the construction industry. This specific industry is known for carrying out tons of projects on various sites around the world, ensuring that structures and buildings will be built for different purposes.

What makes the construction activities dangerous is that there are a lot of elements on project sites that can pose risks to the people and cause damages to the surrounding objects. That is why most contractors and project managers of construction projects have to ensure that safety precautions will be followed. The use of appropriate machines is also required by these professionals, as well as their thorough assessment and maintenance to avoid generating any issues during operations.

Cranes are one of the machines that are typically used during construction.They can easily lift and move heavy loads in a project site without any difficulties, as long as they are established on site correctly.

Basic Components of Cranes

Cranes are comprised of vital components that allow them to conduct their operations. Some of the components of cranes are the following.

  • Tower: Cranes, particularly tower cranes, rely heavily on this specific component for them to rise and reach the intended height of the structure or property. The tower is typically comprised of lattice sections that are stacked on top of each other. A turntable is then situated right on top of the tower, allowing it to rotate fully.
  • Operator’s Cab: Situated near the turntable, the operator’s cab houses the location where the crane operator can manoeuvre and control the actions of the crane.
  • Jib or Boom: The jib, also known as the boom, is a component that is located near the operator’s cab. It stretches out forward for it to reach the areas where the load must go. Connected along this part is a trolley, which enables the heavy load to move around the site.
  • Counter Jib: Counterweights, which are located in the counter jib, help stabilise the crane during the load movement. The counter jib also houses winch and motors. These components help steadily lower or raise the rope to hoist the heavy load.

Lifting and Movement of Load

The safe lifting and movement of the load, which can be structural steel materials and other necessary materials, are often conducted by the crane operator and the riggers. They must work harmoniously to ensure that the whole load movement will be done properly.

No matter what type of crane a project utilises, the lifting and movement of load involve the same basic steps. The first step in lifting and movement of heavy load is to lower the rope so that the load can be connected and attached. And then, the riggers must secure the load into the hook and perform other things that can ensure the security and stability of the lift. Once the load is attached properly, the crane operator will control the whole crane to finally lift and move the load towards its intended location.
