🏗️ Understanding the Key Parts of a Tower Crane Anti-Collision Device (ACD)
Ensure Safety & Precision with Cangraft ACD Systems (Model: HL-50)
📘 Introduction
In today’s high-rise construction projects, tower cranes often operate in close proximity, making collision risk a critical concern. The Anti-Collision Device (ACD) is an intelligent safety system that helps prevent accidents by monitoring crane movement and stopping unsafe actions. At Cangraft Equipment Pvt. Ltd., our HL-50 model is designed with advanced components to ensure real-time monitoring and maximum safety.
Let’s explore the key parts that make up a reliable ACD system.
🔧 Core Components of an ACD Unit
| Component | Function |
|---|---|
| 1. Display / Monitor (with Fixing Cable) | Acts as the control interface for the crane operator. Displays crane position, speed, angle, and alerts. |
| 2. CPU / Mainframe | The central processing unit that receives sensor inputs and processes commands to control crane operations. |
| 3. Transmission Radio | Enables communication between multiple cranes to detect proximity and potential collisions. |
| 4. Antenna (with 10m Cable) | Facilitates signal transmission between cranes and central units. |
| 5. Slewing Encoder (with Cable) | Tracks the crane’s rotation and sends data to the CPU for collision detection. |
| 6. Trolley Limit Switch with Potentiometer & 25m Cable | Detects trolley position on the jib and signals if movement exceeds the safe working range. |
| 7. PLC Control Cable (15/24C) | Industrial-grade cable used to connect all components to the PLC controller. |
| 8. Power Cables & Sockets | Provide stable power connections to all units in the system. |
🔄 Additional Components in ACD + SLI Configuration
For enhanced safety, Cangraft offers a combination of ACD + SLI (Safe Load Indicator), integrating load and wind safety features:
| Component | Function |
|---|---|
| 1. Hoist Limit Switch with Potentiometer & 25m Cable | Monitors vertical hoisting limits to avoid over-travel or dangerous lifting angles. |
| 2. Anemometer with 10m Cable | Measures wind speed and sends alerts if wind conditions are unsafe for crane operation. |
| 3. Load Sensor with Cable | Detects actual load on the hook to prevent overloading, a key component of the Safe Load Indicator. |
✅ Why These Components Matter
Real-time Prevention: The combination of sensors, encoders, and radios ensures immediate response.
Multi-Crane Communication: Ideal for sites with multiple cranes working close to each other.
Plug-and-Play Setup: All components are pre-configured and tested for quick installation.
Integrated Safety: When combined with the SLI system, it prevents both collision and overload—the two most common causes of crane accidents.
🚧 Conclusion
The effectiveness of a tower crane’s Anti-Collision System depends on the quality and integration of each component. At Cangraft, we ensure each part in our HL-50 ACD and ACD+SLI systems is optimized for precision and durability, making your site safer, smarter, and compliant.
