Cranes are popular machines that are used at construction sites. Despite their popularity, crane accidents occur very commonly, leading to severe injuries, deaths, and losses. Knowing how the major accidents that arise when using cranes occur and how they can be cured is vital to achieving safety in the workplace.
Most Common Causes Of Crane Accidents
Many factors of human factor mistakes, mechanical aid faults, and climatic conditions cause crane accidents. The most known accidents are:
Mechanical Failures
- Brake failure caused by lack of maintenance.
- Unexpected drops due to worn-out wire rope.
- Overloaded or faulty hoists and cranes.
Operator Errors
- Inadequate training of crane operators.
- Not monitoring the load or weight balance within the cranes.
- Boom swing radius collisions due to poor operator judgment.
Environmental Factors
- Unstable, strong winds.
- Crane tip-overs from the unlevel ground or bad foundation.
- Fog, rain, or dark can obstruct visibility.
Preventive Measures to Reduce Crane Accidents
Regular Maintenance and Inspections
- Daily operation checks before beginning work.
- Adherence to maintenance schedule.
- Turn staff on before they fail out worn parts.
Comprehensive Operator Training
- OSHA-trained crane operators are certified to use the device.
- Educated crane operators on disciplines periodically.
- Simulated crane maneuvering exercises to improve operators’ responses in case of highly dangerous situations.
Developing Safety Management Systems
- Load limitations are set and monitored through the use of Load Moment Indicators (LMI).
- Operators and ground personnel are integrated for effective teamwork.
- Proper rigging is performed to achieve the desired balance of the load.
Improving Worksite Vigilance
- Barriers are erected around the crane working zones.
- Wind velocity and terrain roughness evaluation is made before any lifts are attempted.
- Use of guides and signalers to assist in crane maneuvering.
Policies for Safety and Risk Management
Safety policies issued by governments and other organizations seek to crane accident risks. Such key policies consist of:
- OSHA Crane Standards in Construction Safety.
- American National Standards Institute (ANSI) for crane usage.
- ISO 12480-1 guidelines on cranes in the heavy industry.
Following these policies can help reduce accidents and legal liability in many cases.
Technological Advances in the Safety of Cranes
There have been technological improvements concerning the operation of cranes. These improvements are:
- Crane movement sensors that automatically avert the crane’s movements from any objects.
- Crane operation through remote control in danger zones.
- AI-based predictive maintenance, where intelligent systems provide warnings for potential failures in machinery.
Standard Guidelines for the Safety of Crane Operators and Worksites
It is advisable to take further safety measures as follows:
- Ensure that the crane is stable before lifting heavy weights.
- Eliminate jerky movements and swift side-to-side movements.
- Require all personnel in and around the work area to wear relevant PPE.
- Prevent unapproved persons from being in the area covered by the lift.
Case Studies for Reducing Crane Accidents
- Installing Load Cells for Overloading Prevention: The construction company was able to integrate overloading sensors in real-time, which helped reduce overloading by 40%.
- Safe Lifting Operations Through Wind Speed Monitoring: Wind speed sensors were fitted to prevent accidents by terminals due to unexpected wind gusts.
