Beyond the loads, the boom angle contributes an essential part to safer lifting operations. A minor change in angle can have a drastic impact on safe lifting.

What do people generally ignore?

The same crane can handle varied loads based on the boom position. The changes in angle change the lifting capacity and risk level.

Understanding the Crane Boom Angles

70° – High Boom Angle – Safe Lifting Zone

  • The load is closer to the crane
  • Delivers utmost strength and stability

45° – Mid Boom Angle (Caution Zone)

  • Lowered lifting power
  • Demands cautious verification with load charts

30° – Low Boom Angle (Danger Zone)

  • Load shifts away from the crane
  • Leads to instability and ripping risks

Core Rules

The risk increases if the boom angle reduces.

Why is it important?

Improper angles can cause overloading of the crane, resulting in equipment failure, tipping, or even causing fatalities.

Hidden Risk

A minor change in boom angle can lead to major impacts on lifting capacity.

Safety Checklist Before Every Lift

  • Review the crane load chart
  • Ensure the load is close
  • Unless needed, don’t plan low-angle lifts

Conclusion

Boom angles have a direct impact on lifting safety. Right planning and angle selection ensure stable and safe crane tasks.
