Top 10 hazards with Mobile Cranes

1. Boom or Crane Collapse

• Overloading or exceeding the crane’s rated capacity can lead to structural failure.
• Improper assembly or disassembly can also cause collapses.

2. Two-Blocking

• Occurs when the hook block, overhaul ball, or similar component contacts the boom tip or fixed upper block.
• This can snap the hoist rope, dropping the load or causing catastrophic failure.

3. Overhead Power Lines (Electrocution Hazard)

• Cranes operating near power lines can accidentally contact them, resulting in severe injury or fatalities.
• Electrocution can occur even without direct contact due to arcing.

4. Load Drops & Unsecured Loads

• A load can fall due to rigging failures, improper lifting techniques, or sudden movements.
• Poorly secured loads can shift, increasing the risk of injury.

5. Instability & Tip-Overs

• Working on uneven or unstable ground without proper outriggers or counterweights can cause tipping.
• Improper setup or extending the boom too far can also make the crane unstable.

6. Poor Weather Conditions

• High winds can cause loads to swing uncontrollably or make the crane unstable.
• Rain, ice, or snow can reduce traction, visibility, and control.

7. Mechanical Failures & Lack of Maintenance

• Worn-out ropes, malfunctioning brakes, or hydraulic system failures can lead to serious accidents.
• Routine inspections and proper maintenance are crucial to prevent these issues.

8. Struck-By Hazards (Swing Radius & Load Movement)

• Workers in the swing radius of the crane risk being hit by the boom or counterweight.
• Moving loads can strike workers, causing severe injuries or fatalities.

9. Communication Failures

• Miscommunication between the operator and signal person can lead to dangerous movements.
• Poor visibility or lack of proper signals increases accident risks.

10. Improper Training & Human Error

• Untrained or inexperienced operators may make poor decisions under pressure.
• Mistakes in rigging, signaling, or equipment operation can lead to accidents.
