Cranes Are Often The Most Powerful Equipment On The Job

Cranes are one of the most powerful and essential pieces of equipment on construction sites. Their ability to lift and move heavy loads makes them indispensable, but it also means they come with significant risks. These machines require trained operators who understand how to handle them safely. Without proper training and adherence to safety protocols, cranes can lead to serious accidents.

According to the Bureau of Labor Statistics (BLS) and OSHA, approximately 40 construction workers die each year due to crane-related incidents. To mitigate these dangers, cranes weighing over 2,000 pounds must be operated by certified professionals through the National Commission for the Certification of Crane Operators (NCCCO). Companies that use cranes are legally responsible for any harm caused to workers or bystanders, 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, and structures.
  2. Ensure slings, chains, and straps meet or exceed the load's weight rating and have clear tags indicating their safe working limit.
  3. Identify potential pinch and crush points around the crane and the landing area, marking them with paint or chalk for visibility.
  4. Set up barriers around the crane’s swing radius to prevent unauthorized access to hazardous zones.
  5. Confirm the load is balanced and all items are clear of the path of movement.
  6. Follow a detailed lift plan for all major lifts, distribute copies to the team, and update as needed.

Checklist of critical items to monitor while moving a load

  1. Never allow anyone to work or stand under a suspended load.
  2. Maintain a safe distance from the crane during lifting operations.
  3. The operator must remain focused and avoid distractions like phone calls or texting.
  4. A trained signalman must be present, using standardized hand signals to communicate with the operator.
  5. Only one person should give signals at a time to avoid confusion.
  6. Use an air horn to alert workers of ongoing lifts and ensure everyone is aware of the crane's activity.
  7. Avoid raising the load higher than necessary.
  8. Never leave a load hanging in the air unattended.

Toolbox Talk Outline

  • Discuss the task at hand and its objectives.
  • Review the checklists provided above.
  • Address safety concerns, including environmental hazards, PPE usage, first aid, and emergency procedures.
  • Allow time for questions and feedback from the crew.
  • Conduct a brief quiz to ensure all team members understand the safety guidelines.

Safety Equipment - Signs, Stickers, Air Horns & Lights

Safety Signs and Stickers

Safety signs and stickers are vital for communicating risks to workers and bystanders. OSHA and ANSI provide guidelines for signage at job sites. Crane warning labels are typically made from durable materials like vinyl, polyester, or aluminum. You can find these signs on platforms like SafetySign.com and Amazon.

Bilingual signs may be necessary in areas where multiple languages are spoken to ensure all workers understand the warnings.

Air Horns / Audible Alarm Sirens

Before lifting, use an air horn or audible alarm to notify nearby personnel and clear the area. After the lift, signal “all clear.” Different horn patterns help distinguish between pre-lift, mid-lift, and post-lift alerts. This ensures everyone is aware of crane activity, even if they aren’t directly watching the machine.

Safety Lights

Proper lighting is essential for visibility, especially when natural light changes throughout the day. Warning lights around the crane help identify its location and reduce the risk of accidents. These lights are particularly important in low-light conditions or during inclement weather.

Transportation

Transporting large cranes requires careful planning, especially in urban or complex industrial environments. Before moving, map out the route and measure clearance to ensure the crane can pass safely. Extra space should be allowed for turns and tight spaces.

Spotters are often used to guide the crane through tight areas, and communication between the driver and spotters must be constant. Oversized load signs, bright flags, and police escorts may be required depending on local regulations. Always check weight limits, especially when crossing bridges or elevated roads.

Lift Plan

A lift plan is crucial for ensuring safe and efficient crane operations. It outlines the details of the lift, including the weight of the load, the crane’s capacity, and the location of the center of gravity. The plan also includes information about rigging gear, height restrictions, and risk mitigation strategies.

The lift plan should be shared with all involved parties and updated regularly. Everyone on the site must have access to the latest version to maintain consistency and safety.

OSHA Crane Safety Hand Signals

Hand signals are a key part of crane operation, allowing operators and signal persons to communicate visually. OSHA has established standard hand signals for crane operations. Below are some of the most common ones:

OSHA Crane Hand Signal - Stop
Stop
With arm extended horizontally to the side, palm down, arm is swung back and forth.
OSHA Crane Hand Signal - Emergency Stop
Emergency Stop
With both arms extended horizontally to the side, palms down, arms are swung back and forth.
OSHA Crane Hand Signal - Hoist
Hoist
With upper arm extended to the side, forearm and index finger pointing straight up, hand and finger make small circles.
OSHA Crane Hand Signal - Raise Boom
Raise Boom
With arm extended horizontally to the side, thumb points up with other fingers closed.
OSHA Crane Hand Signal - Swing
Swing
With arm extended horizontally, index finger points in direction that boom is to swing.
OSHA Crane Hand Signal - Retract Telescoping Boom
Retract Telescoping Boom
With hands to the front at waist level, thumbs point at each other with other fingers closed.
