Key components of a construction crane

When you think of towering structures in construction projects, cranes are often the backbone of progress.

At BJW Crane Hire, we provide a variety of cranes tailored to meet the demands of every project.

But what makes a crane such an essential machine on construction sites? Keep reading to find out.

 

1. The boom

The boom is the most visible and recognisable part of a crane. It’s the long arm that extends from the crane’s base and is used to lift heavy materials. There are two types of booms commonly used in cranes:

• Lattice boom – A lighter boom with greater reach, often seen in crawler cranes.
• Telescopic boom – Consists of multiple sections that extend and retract for easy transportation and storage.

Both types have their advantages depending on the project requirements, but their purpose remains the same: reaching elevated heights and supporting large loads.

2. The jib

Also known as the jib arm or the jib extension, this component works as an extension of the boom.

The jib increases the overall reach of the crane, making it possible to lift loads over greater distances. This is especially useful in congested construction sites or when working at extreme heights.

3. Counterweights

To ensure stability during lifts, cranes are equipped with counterweights. These are placed at the rear of the crane’s base to balance the load being lifted by the boom.

Without counterweights, the crane could easily become unbalanced, making it unsafe for operators and workers on site.

 

4. The slewing unit

Slewing refers to the crane’s ability to rotate the boom and jib horizontally.

The slewing unit enables the crane to turn in a full circle or at various angles, giving operators the flexibility to position materials wherever needed. This is a crucial feature for any crane, especially on projects requiring precision.

 

5. The hook

The hook is attached to the end of the crane’s boom via cables, pulleys, and hoists, and lifts the load.

Modern cranes use high-strength steel hooks to safely and securely lift loads that can weigh several tons. The hook also includes safety latches to prevent the load from slipping during lifting.

 

6. Outriggers

Outriggers are the stabilising legs that extend from the base of mobile cranes. These adjustable legs provide additional support and prevent the crane from tipping over during operations.

They are especially important when working on uneven terrain or handling particularly heavy loads.

7. The hoist

The hoist is responsible for raising and lowering the load. It is typically operated by a hydraulic system, allowing for smooth and controlled movements.

Hoists work together with the hook and the boom, ensuring that the load is safely moved to its destination.

 

Why do these components matter?

Each of these components plays a vital role in ensuring the crane operates smoothly and safely.
