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.

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. And cranes can be debided into different types such as Overhead Crane, Gantry Crane& and Port Crane.

While there are many different types of cranes, there are a few basic components or Crane Accessories like Hoist and Trolley worth mentioning. The main parts that can be found on a crane are as follows.

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.

The Jib

The jib crane is the lattice-type structure attached to the end of the boom. Using a lattice-type build helps to reduce the weight it adds to the front of the boom. It is fixed in length and cannot be extended or retracted like a boom can. Some versions of mobile cranes have a jib fixed to the end of the boom to help move and lift materials. The jib or jib arm has one main purpose: to help keep the material clear of the main support so that it doesn't hit it while being moved. That being said, jibs are not always required and are often looked at as extra pieces that can be used when needed.

The Rotex Gear

The Rotex gear is the mechanism below the cab of the crane. It allows the cab and boom to rotate left and right. A simple movement, but incredibly important for the function of the machine.
