Understanding the different types of cranes can help in selecting the most suitable one for a specific job. Here is an overview of three common types of cranes: 

Mobile Cranes

Mobile cranes are versatile and easily transportable, making them ideal for projects that require frequent relocation. With their wheeled or tracked chassis, they can efficiently manoeuvre around job sites. Offering flexibility and the ability to handle different lifting capacities, mobile cranes are suitable for a wide range of construction projects.

Tower Cranes

Tower cranes are commonly found on large construction sites, featuring a vertical mast and an adjustable horizontal jib. They offer exceptional lifting capacity and height reach, making them well-suited for tall structure construction. Tower cranes provide stability, enabling the lifting of heavy loads to significant heights, but require a sturdy base and anchorage for safe and stable operation.

Overhead Cranes

Overhead cranes are versatile machines commonly used in industrial settings. They excel in moving heavy loads within a fixed area, offering precise control and efficient material handling capabilities.

 

To ensure safe and efficient lifting operations in the construction industry, crane operators and project managers must consider the following factors when selecting a crane for a specific job:

  • Weight and Dimensions: Determine the weight and dimensions of the load to ensure that the crane’s lifting capacity is sufficient. Consider factors like load radius and the crane’s load chart to determine its suitability.

  • Height and Reach: Evaluate the required height and reach of the crane based on the project’s needs. Tower cranes are well-suited for tall structures, while mobile cranes with telescopic booms are versatile for various height requirements.

  • Terrain and Environment: Consider the terrain and environment of the job site. Rough terrain cranes are designed for off-road conditions, while mobile cranes with outriggers provide stability on uneven ground.

  • Access and Site Constraints: Evaluate the available space and any site constraints that may affect the crane’s movement and operation. Tower cranes require sufficient space for their base and clearance for their jib.

 

Crane Components

 Understanding the key crane components and their functions is crucial for safe and efficient crane operation. Let’s explore them:

Boom

The boom is a component that extends horizontally from the main body of the crane. It provides the crane with its reach and lifting capacity. The boom can be adjusted in length and angle to accommodate various lifting requirements and reach specific heights or distances.

Hoist

The hoist is a vital component of a crane responsible for lifting and lowering loads. It consists of a motorised drum or pulley system with ropes or chains that are used to suspend and control the movement of the load. The hoist enables precise lifting and positioning of heavy objects, allowing for efficient material handling during crane operations.

Jib 

The jib is an optional component that extends from the main body of the crane. It provides additional reach and manoeuvrability. The jib can be fixed or luffing, allowing for vertical movement. Luffing jibs are especially useful for operations that require the crane to lift loads to different heights and angles.

Controls

Crane controls are located in the operator’s cab. The joysticks, buttons, and switches allow operators to extend or retract the boom, rotate the crane, raise or lower the load, and perform essential functions. Advanced cranes may include computerised load monitoring and automatic positioning features in their control systems.

Component Maintenance

Proper maintenance of crane components is essential for safe and reliable operation. It can include lubricating moving parts, inspecting wire ropes, checking hydraulic systems, and verifying safety device functionality. By maintaining components, crane owners enhance equipment longevity and reduce the risk of accidents.

 

Pre-Operational Checks

Pre-operational checks are vital for crane operators to ensure safety, verify crane readiness, and prevent accidents or equipment failures. Here is a concise checklist for crane operators to follow before starting lifting operations:

  • Visual Inspection: Check for visible damage, loose or missing parts, leaks, and signs of wear on the boom, hook, outriggers, jib (if applicable), and safety devices.

  • Load Chart: Review the accessible and legible load chart that provides lifting capacities at different boom lengths, angles, and configurations.

  • Wire Ropes and Slings: Inspect wire ropes and slings for damage, such as broken wires or excessive wear. Ensure proper reeving, secure attachments, and lubrication.

  • Outriggers and Stabilisers: Verify proper extension, level positioning, secure locking mechanisms, and absence of fluid leaks. Ensure stable ground support.

  • Tires or Tracks: Check tire condition, inflation, tread depth (if applicable). For tracks, ensure intact and properly tensioned tracks without excessive wear.

  • Safety Systems: Test emergency stop buttons, limit switches, alarms, and load moment indicators to ensure they are functional and responsive.

 

When interpreting the load chart, operators should:

  1. Identify the crane’s configuration and boom length.

  2. Determine the maximum allowable load based on specified radius and boom angle.
  3. Verify the weight and dimensions of the load to ensure they are within the crane’s capacity.
  4. Consider additional factors mentioned in the load chart, such as wind speed, ground conditions, or attachment restrictions.

 

Following these pre-operational checks and effectively utilising the load chart, operators ensure crane safety and the ability to lift loads within its capacity. Regular training, referencing guidelines like the Construction Plant-hire Association (CPA), and collaboration with competent personnel are essential for safe and efficient crane operations.

 

Safe Lifting Practices

Safe lifting practices are paramount for crane operators to prevent accidents, ensure the well-being of personnel, and protect equipment. By following proper rigging techniques, maintaining clear communication, and adhering to safety protocols, operators can minimise risks and maintain a safe work environment. Let’s explore key aspects of safe lifting practices:

Rigging Techniques

  • Use appropriate and inspected rigging equipment, including slings, shackles, and hooks.

  • Rig loads correctly, ensuring proper weight distribution and secure attachments.

  • Avoid sharp edges or rough surfaces that could damage the rigging or compromise load stability.

  • Use taglines to control load swing and ensure precise positioning.

Load Positioning 

  • Position the load directly beneath the hook, maintaining stability and preventing swinging.

  • Avoid placing loads near the crane’s capacity limits to prevent overloading and compromising stability.

  • Ensure the load is clear of obstructions or obstacles during lifting and movement.

  • Pay attention to the centre of gravity of the load to maintain stability.

Clear Communication 

  • Establish clear communication channels with ground personnel, using standardised hand signals or two-way radios.

  • Confirm that all personnel involved in the lifting operation understand the signals and instructions.

  • Maintain constant communication to ensure safe coordination between the operator and ground personnel.
