Types Of Cranes Used In Construction (12 Types)

A crane is a powerful machine designed to lift and move heavy loads, machinery, materials, and objects for various purposes. These machines play a crucial role in many industries, including construction, manufacturing, shipbuilding, and material handling. In this article, we’ll explore different types of cranes commonly used in construction.

Components of a Crane

While there are various types of cranes tailored for specific project requirements, they generally share some basic components:

  1. Boom: The long arm responsible for lifting, moving, and placing materials. It can be telescopic or fixed, determining the crane’s range.
  2. Jib: A lattice-type structure attached to the end of the boom to keep the main support material clear when in motion.
  3. Rotex Gear: A mechanism under the crane cab allowing the rotation of the cab and boom to the left and right.
  4. Outriggers: Support structures that distribute the load over a large area, preventing the crane from falling or becoming unstable.
  5. Counterweights: Additional weights placed opposite the load to counterbalance the equipment.
  6. Reinforced Steel Cable: Used to lift, move, and position materials.
  7. Hook: The attachment point for materials, facilitating the lifting process.

Types of Cranes Used in Construction

1. Truck-mounted Crane

A crane with a single engine is used for both the chassis and the crane. Mounted on a rubber trolley for easy maneuverability, it can rotate up to 180 degrees.

2. Level Luffing Crane

Characterized by a hinged jib, maintaining a level hook while the jib moves up and down. Ideal for unloading and loading container ships.

3. Railroad Crane

Designed for railway construction, repair, and maintenance, equipped with flanged wheels for movement on rails.

4. Telescopic Crane

Features a large extendable boom with tubes that increase in length using a hydraulic system. Suitable for various tasks, including disaster rescue operations.

5. Aerial Crane

Also known as sky cranes, these helicopter-like cranes carry large loads, especially in challenging terrains like mountains or during disaster rescue operations.

6. Tower Crane

Widely used in building tall structures, fixed on the ground during construction and anchored with large screws.

7. Floating Crane

Utilized in bridge and port construction and loading and unloading ships. Capable of rescuing sunken ships with a high capacity of up to 9000 tons.

8. Telescopic Handler Crane

Equipped with a forklift-type end of the boom, used for handling pallets of bricks, installing steel trusses, and more.

9. Harbour/Port Crane

Specifically used in harbors for loading or unloading ships, known for their flexibility and ease of use.

10. Crawler Crane

Mobile cranes with belt movement, eliminating the need for outriggers. Suitable for heavy-load transport on construction sites.

11. Rough Terrain Crane

Designed for new and undeveloped sites, offering increased mobility and better traction with outriggers for stability.

12. All-terrain Crane

A mobile crane capable of working on both paved roads and uneven terrain, equipped with more wheels for versatility.

Understanding these types of cranes helps in choosing the right one for specific construction needs. Stay tuned for more updates on construction equipment and safety tips.
