Stop Two-Blocking Accidents Before They Happen: Protect Your Crew & Bottom Line

Is your crane operation a ticking time bomb? One overlooked detail – a missed warning – could lead to catastrophic two-blocking, resulting in equipment damage, injuries, or even fatalities. Don't let complacency compromise safety. This isn't just a sticker; it's an investment in peace of mind and regulatory compliance.

Our Anti Two Blocking (A2B) sticker provides a clear, visible reminder to prevent two-blocking incidents. Ensure your operators are constantly aware of the risks and maintain a safe working environment. Avoid costly repairs, downtime, and potential legal liabilities.

  •   Durable & Reliable: Made from high-quality, weather-resistant vinyl with a permanent adhesive, ensuring long-lasting visibility even in harsh environments. Specifically designed for greasy surfaces!

  •   Protect Your Reputation: Avoid costly accidents and fines that can damage your company's reputation and put your business at risk.

  •   Easy to Install: Simply clean the surface, peel off the backing, and apply. Get your cranes compliant and protected in minutes. Sticker Size: 3.75" x 4.75".

  •   Peace of Mind on Every Lift: Helps prevent dangerous situations by reminding operators about critical safety precautions related to Load Moment Indicators (LMI), Rated Capacity Limiters (RCL), and Boom Angle Indicators.

Imagine the scene: a seasoned operator, momentarily distracted, starts a lift... Without a clear visual reminder, the hook block approaches the boom, causing a two-blocking incident. The crane groans, metal screams, and the whole operation grinds to a halt.

Two-blocking – when the hook block or load block comes into contact with the boom tip – is a completely preventable disaster. Our Anti Two Blocking sticker acts as a constant visual cue, reminding operators to stay vigilant and maintain safe distances. It's a simple, cost-effective solution to a potentially devastating problem.

Ensure your Two Blocking Sticker warning language meets ANSI Z535 standards.

This Anti Two-Blocking Sticker is printed with the text:

DANGER, Two Blocking The Crane Will Cause Death, Serious Injury, Or Property Damage. Do not allow the hook block to contact the boom tip by hoisting up, extending, or lowering the boom.

Our Two Blocking Sticker for A2B Crane Safety is created, printed, cut, and shipped in the USA.

On a boom truck, the decal is designed to be mounted inside the operator cab in a prominent position within the operator's direct line of sight. It can also be applied to the exterior housing of the truck or directly onto the boom structure near the control station. This layout provides a constant visual cue to prevent hook block contact with the boom tip during operations.

This decal is designed to meet or exceed the safety signaling requirements of the ASME B30.5 standard for mobile and locomotive cranes. It supports these standards by providing a highly visible warning regarding the dangers of hook block contact with the boom tip. Additionally, the sticker's warning language is designed to meet ANSI Z535 standards to ensure proper compliance during crane operations.

Absolutely not. This sticker is a supplemental safety tool. It reinforces the importance of proper training, regular inspections, and adherence to established safety protocols. It's one layer of protection in a comprehensive safety program. The sticker provides a visual warning in conjunction with Load Moment Indicator (LMI) and Rated Capacity Limiter (RCL) Systems.

For mobile cranes, the anti two-blocking sticker mounts either inside the operator's cab in a highly visible area near the controls or on the crane superstructure at eye level. It features a high-strength permanent adhesive specifically designed to bond securely to greasy or painted metal crane surfaces. This ensures the warning remains legible and in place even in demanding operating environments.
