Cranes Are Often The Most Powerful Equipment On The Job

Cranes are some of the most powerful and essential machines on construction sites. Their ability to lift and move heavy loads makes them indispensable, but this power also brings significant risks if not handled properly. Operators must be trained and certified to ensure that everyone on site remains safe.

According to OSHA and BLS data, about 40 construction workers lose their lives each year due to crane-related accidents. To mitigate these risks, cranes weighing over 2,000 pounds are strictly regulated, and operators must hold a valid certification from the National Commission for the Certification of Crane Operators (NCCCO). Companies operating cranes are legally responsible for any damage or injury caused, which is why many opt for specialized insurance coverage.

Checklist of critical items to monitor before moving a load

  1. Inspect the area for overhead obstructions such as power lines, trees, or structures.
  2. Ensure slings, chains, and straps are rated for the load and have clear tags showing their safe working limit.
  3. Identify and mark pinch and crush points around the crane and the landing area with paint or chalk.
  4. Set up barriers in the swing radius of the crane to prevent unauthorized access.
  5. Confirm the load is balanced and free of obstructions in its path.
  6. Follow a detailed lift plan for all major lifts and share copies with the crew.

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 during lifting operations.
  3. Operators must remain focused and avoid distractions like phone calls or texting.
  4. A trained signalman is required to communicate with the operator using standardized hand signals.
  5. Only one person should give signals at a time unless it's an emergency situation.
  6. Use an air horn to alert people when a lift is in progress.
  7. Avoid raising the load higher than necessary.
  8. Never leave a load hanging in the air unattended.

Toolbox Talk Outline

  • Start by discussing the task at hand.
  • Go over the pre-lift and during-lift checklists.
  • Review safety protocols, including PPE, first aid, and emergency procedures.
  • Encourage questions and feedback from the team.
  • Conduct a quick quiz to ensure everyone understands the key points.

Safety Equipment - Signs, Stickers, Air Horns & Lights

Safety Signs and Stickers

Clear and visible safety signs are crucial for communicating hazards on a job site. OSHA and ANSI guidelines recommend specific visual cues for crane areas. These signs are typically made from durable materials like vinyl, polyester, or aluminum and can be found online or at local suppliers.

In multilingual areas, consider using bilingual signs to ensure all workers understand the warnings.

Air Horns and Audible Signals

Before a lift, use an air horn or audible alarm to notify nearby workers. After the lift, use an "all clear" signal. Different horn patterns help distinguish between warning and clearance.

These signals are especially important because not everyone may see the crane in action.

Safety Lights

Lighting is essential for visibility, especially in low-light conditions or bad weather. Warning lights can be placed around the crane to alert workers of its presence and the associated risks.

Transportation

Transporting large cranes requires careful planning, especially in busy urban or industrial areas. Measure the intended route and account for extra space around corners and tight spots.

Having spotters on either side of the crane can help guide the driver safely through narrow passages. Always maintain communication between the driver and spotters.

Oversized load signs and flags are often required, and in some cases, police escorts may be necessary. Check local regulations to ensure compliance.

Lift Plan

A lift plan is similar to an architectural blueprint—it outlines how a lift will be executed safely. It includes details such as load weight, center of gravity, dimensions, lifting points, and risk mitigation strategies.

Engineers or experienced professionals typically create these plans, and they should be shared with all involved parties. Updates should be communicated promptly to ensure everyone follows the same procedure.

OSHA Crane Safety Hand Signals

Effective communication between the crane operator and the signal person is vital. OSHA has established standard hand signals to ensure clarity and safety. Below are some of the most commonly used signals.
