Cranes Are Often The Most Powerful Equipment On The Job

Cranes are typically the largest and most powerful machines found on construction sites. Their immense size and lifting capabilities make them essential for moving heavy materials, but these same features also pose significant risks if not handled properly. Operators must be well-trained to ensure that everyone on site remains safe, from workers to nearby bystanders.

According to data from the Bureau of Labor Statistics (BLS) and the Occupational Safety and Health Administration (OSHA), about 40 construction workers lose their lives each year due to crane-related accidents. To prevent such tragedies, cranes weighing over 2,000 pounds are subject to strict regulations. Operators must be certified by the National Commission for the Certification of Crane Operators (NCCCO). Additionally, companies are legally responsible for any damage or harm caused by crane operations, which often leads to the purchase of specialized insurance coverage.

Checklist of critical items to monitor before moving a load

  1. Check for overhead obstructions like power lines, trees, and structures before starting the lift.
  2. Ensure that slings, chains, and straps have proper load ratings and safety tags indicating their maximum working capacity.
  3. Identify and mark areas where pinching or crushing hazards may occur, both around the crane and at the landing zone.
  4. Establish a clear barrier around the crane’s swing radius to prevent unauthorized access during operation.
  5. Confirm the load is balanced and free of obstacles in its path of movement.
  6. Develop and share a detailed lift plan with all relevant personnel. Any changes should be communicated immediately.

Checklist of critical items to monitor while moving a load

  1. Never allow anyone to stand under a suspended load.
  2. Keep all personnel at a safe distance from the crane during lifting operations.
  3. Crane operators must remain focused and avoid distractions like phone calls or texting.
  4. A trained signal person must be present, using standardized hand signals to communicate with the operator.
  5. Only one person should give signals at a time unless it's necessary for safety reasons.
  6. Use an air horn to alert people when a lift is in progress.
  7. Avoid raising the load higher than needed.
  8. Never leave a load hanging in the air unattended.

Toolbox Talk Outline

  • Start with a brief discussion of the day’s tasks.
  • Go over the pre- and during-lift checklists.
  • Cover safety concerns, including PPE, first aid, emergency procedures, and environmental hazards.
  • Encourage open dialogue and questions from the crew.
  • Consider a short quiz to ensure everyone understands the key points.

Safety Equipment - Signs, Stickers, Air Horns & Lights

Safety Signs and Stickers

Safety signs and stickers are crucial tools for communicating risks on a job site. OSHA and ANSI provide guidelines for effective signage, especially for cranes. These signs help raise awareness among workers and visitors, reducing the likelihood of accidents.

Common materials used for crane warning labels include vinyl, polyester, aluminum, and plastic. Many suppliers, such as SafetySign.com and Amazon, offer a variety of options. In multilingual areas, consider using bilingual signs to ensure clarity for all workers.

Air Horns and Audible Alarms

Before lifting, use an air horn or audible alarm to notify nearby personnel and clear the area. After the lift is complete, use an “all clear” signal. Different horn patterns can be used for different stages of the process.

These auditory cues are important because not everyone may be directly watching the crane, especially in busy environments.

Safety Lights

Proper lighting is essential for visibility, especially in low-light conditions or bad weather. Warning lights help distinguish the crane from its surroundings, making it easier for workers to spot and avoid potential hazards.

Installing spotlights around the crane can help increase awareness of its presence and reduce the risk of accidents.

Transportation

Transporting large cranes requires careful planning, especially in urban or complex industrial settings. It's vital to study the route beforehand and measure all dimensions to ensure the crane can move safely. Extra space should be accounted for around turns and tight spaces.

Having spotters on either side of the crane during maneuvering can improve safety. The driver and spotters should maintain constant communication through visual or auditory means.

Oversized load warnings, such as flags and signs, are often required by law. Some routes may even need police escorts or special permits. Always check weight limits, especially when crossing bridges or elevated roads.

Lift Plan

A lift plan is similar to an architectural blueprint—it requires careful design and preparation. Engineers create these plans based on specific job requirements, ensuring all aspects of the lift are considered.

Key elements of a lift plan include:

  • Load weight and crane capacity
  • Center of gravity location
  • Maximum load dimensions
  • Lifting points and rigging gear
  • Height restrictions and obstacles
  • Risk assessment and mitigation strategies
  • Detailed method statement, including costs and site impact

Once created, the lift plan must be shared with all involved parties. Changes should be updated and distributed promptly to avoid confusion.

OSHA Crane Safety Hand Signals

Clear communication between the crane operator and signal person is essential. OSHA has established standard hand signals that must be followed to ensure safety and coordination.
