4 Types Of Cranes And Their Functions

Did You know Cranes Have Been Around for around 2,000 Years?!

The main purpose of a crane is to lift extremely heavy amounts of weight. A typical crane is equipped with a hoist rope, wire ropes or chains and sheaves. These machines use levers and pulleys that perform jobs which humans are not able to do on their own. They are used to lift and lower materials and also to move them horizontally and transport these items to other places. Cranes date back 2,000 years and were used to build huge monuments, Egyptian pyramids and even medieval churches.

Modern day cranes are used for:

  • Construction Materials
  • Bridges
  • Railroad Tracks
  • Shipping Materials/Equipment
  • Cars
  • Scrap Metal
  • Mobile Homes

These are just a few of the items cranes are able to transport, but they are equipped to virtually move any heavy item that needs to be moved. Let’s take a look at a few different types of cranes and their functions. If your business depends on heavy lifting, fast loading cycles or the most delicate precision, loader cranes are a great investment.

4 Types of Cranes –

    1. Mobile Crane – Mobile cranes are the most basic type of crane and are mounted on a mobile platform. Mobile cranes can be just a telescopic boom on a platform, or they can be a full sized crane. These cranes functions are to lift heavy objects, with the flexibility to access sites that may be difficult for other types of cranes to access. They are equipped with a wire rope drum, chains and a control panel.


    1. Loader Cranes – Loading cranes main function is to load and unload trucks and other vehicles. They are operator friendly and offer a high level of cost efficiency. To load equipment onto a trailer, a loader crane with hydraulically powered articulated arm is used to load items onto a truck. They can also be used for loading and unloading of heavy cargo and machinery in tight and restricted spaces. The knuckle boom loader crane is an excellent crane for this type of work.


    1. Tower Cranes – Tower cranes are used during the construction of tall buildings/skyscrapers and are considered to be the tallest types of cranes. Some tower cranes can reach up to 256 feet and outwards of 230 feet. The cranes are fixed to the ground by mounting a strong concrete pad, so anchor bolts can be embedded into the pad. While being secured, this allows the crane to balance when lifting heavy loads. These cranes are also often assembled and affixed inside the building itself during construction.


  1. Overhead Cranes – Overhead cranes are also known as suspended cranes. These cranes are used in factories and lift very head loads. Since the load is extremely heavy, the hoist is set on a trolley that will move in one direction along one or two beams, which move along an elevated or ground level tracks.
