Cranes are different from other pieces of construction equipment because – at their most basic function – they do not require other machinery or power to function. The bulldozer, excavator or tractor required some form of power – whether it be steam or gas, or oil. Many modern construction equipment dates back to some time in the 1900s. Not the crane. The crane is the grandfather of all construction equipment.
What Is a Crane?
A crane is a machine that is used to lift and move heavy loads, machines, materials, and goods for a variety of purposes. They are used in all different sectors of industry, from construction to manufacturing to shipbuilding and material loading. Cranes are common along skylines as they are necessary to build the skyscrapers we so often see in our cities today.
The Basic Components of the Crane
While there are many different types of cranes, there are a few basic components worth mentioning. The main parts that can be found on a crane are the:
Boom
- Jib
- Rotex Gear
- Outriggers
- Counterweights
- Reinforced-steel cable
- Hook
The Boom
The boom is the most recognizable part of a crane. The boom is a long arm that can either be telescopic or fixed. They take on a variety of roles depending on the type of crane and how it is built. They are able to work without jibs and are sometimes the main component on a crane.
The primary purpose of the boom is to lift, move and position material. They bear the majority of the load and are responsible for determining the reach of the crane.
