The IntelliSafe Crane Hook Proximity Limiter is an advanced, state-of-the-art safety system designed to prevent costly collisions and dangerous accidents by automatically monitoring and controlling the hook’s proximity to the crane’s boom tip or other critical structures. This system is the definitive solution for enhancing safety, protecting your infrastructure, and maximizing operational uptime.

A primary cause of crane-related damage and failure is the over-hoisting of the mobile crane hook block, leading to catastrophic “two-blocking” incidents. The IntelliSafe Proximity Limiter acts as an intelligent guardian, continuously measuring the distance between the hook and the boom tip. It provides clear warnings and, if necessary, automatically cuts hoist power to prevent contact, safeguarding your crane, load, and most importantly, your crew.

Crane Hook Proximity Limiter Key Features & 好處

• 1. Automatic Collision Prevention: The system intervenes automatically by disengaging the hoist function when a dangerous proximity is detected, eliminating reliance solely on operator vigilance.
• 2. Two-Stage Warning System:
  • 階段 1 – Pre-Warning: An audible alarm and visual beacon activate at a pre-set safe distance, alerting the operator to slow down.
  • 階段 2 – Hard Shutdown: If hoisting continues, the system triggers an immediate and automatic cut-off of the hoist-up motion at the second, closer set-point, preventing impact.
• 3. Advanced Sensing Technology: Utilizes highly reliable non-contact sensors (例如。, ultrasonic, laser, or radar) immune to environmental factors like dust, 水分, and temperature fluctuations, ensuring consistent performance in harsh conditions.
• 4. Robust and Durable Design: Engineered with industrial-grade materials, the sensor and all components are built to withstand shock, vibration, and exposure, guaranteeing longevity and reliability on any job site.
• 5. Easy Installation & Calibration: Designed for retrofitting onto existing cranes of all types (mobile, tower, overhead) and seamless integration into new builds. The intuitive setup wizard allows for quick and precise calibration.
• 6. Self-Testing Diagnostics: The system continuously performs self-checks upon startup and during operation to confirm all components are functioning correctly, providing peace of mind and meeting safety compliance requirements.
• 7. Data Logging Capability (選修的): Records operational data and event history (例如。, near-misses, shutdowns), providing valuable insights for safety audits, maintenance planning, and operator training.

How It Works

• 1. Sensing: A robust sensor is mounted on the crane’s boom tip, continuously measuring the exact distance to the hook block or ball.
• 2. Processing: The distance data is transmitted to the central processing unit (CPU) in the cab.
• 3. Alerting: The CPU compares the real-time distance to the pre-programmed setpoints.
• 4. Action: The system activates alarms and executes a controlled shutdown sequence if the hook approaches the danger zone, preventing a collision.
