Wtau Anti-Collision System Integrated Solutions: UWB, Laser, 3D Spatial

Anti-Collision Systems: Which One Is Right for You? Many customers have asked us: “Wtau offers so many anti-collision systems—laser, microwave, spatial algorithm… Which one is the best fit for us?” There’s no need to worry. Every Wtau anti-collision system is designed for specific application scenarios. In this article, we explain them in plain language to help you quickly choose the right solution for safe and efficient lifting operations.

Wtau anti-collision systems are developed based on three core technologies, each with clear technical priorities and performance to precisely match different operational needs.

1. Microwave Radar (UWB) Anti-Collision System

Core Technology:Adopts non-contact microwave ranging technology to realize real-time monitoring of distance, speed, and direction via radio waves, completing dynamic data calculation within 0.1 seconds.

Key Performance:Strong anti-interference capability, unaffected by environmental factors such as electromagnetic interference, rain, snow, smoke, and dust; works normally in dark or poor lighting conditions.

Outstanding Advantages:Compact size, easy installation, controllable cost, no need for complex debugging, and adaptable to rapid integration with various machine types.

Application Scenarios:Environments with harsh conditions, such as metallurgical plants and bulk cargo loading/unloading sites; scenarios with heavy dust, frequent rain/snow, or insufficient lighting.

Typical Applications:

Overhead Crane Anti-Collision:Prevents collisions between cranes on the same track or different levelsClick for details

Tower Crane Anti-Collision:Avoids collisions between tower cranesClick for details

Mobile Crane Anti-Collision:Protects crane booms from hitting obstaclesClick for details

2. Spatial Algorithm Anti-Collision System

Core Technology:Based on "spatial modeling + real-time calculation", it builds a 1:1 3D model of the site and equipment, updates the equipment position in real time through a unified coordinate system, and calculates the minimum distance between components.

Key Performance:Flexible adjustable monitoring distance, strong anti-interference capability (almost unaffected by the environment, only influenced by Beidou positioning status), and support for collaborative obstacle avoidance of multiple devices.

Outstanding Advantages:Enables three-level progressive protection (early warning, deceleration, and stop), and adapts to multi-device cross-operation in complex dynamic scenarios.

Application Scenarios:Scenarios with cross-operation, movement, and combined lifting of multiple lifting devices, such as docks, shipyards, nuclear power/hydropower construction sites, and large-scale infrastructure sites.

Typical Applications:

Multi-tower Collaborative Anti-Collision:For complex tower crane groupsClick for details

3D Anti-Collision for Ports & Shipyards:Between gantry cranes, portal cranes, bridge cranes and ship hullsClick for details

3. Laser Radar Anti-Collision System

Core Technology:Centered on "laser ranging + point cloud processing", it acquires 3D point cloud data through multi-line laser scanning, and accurately identifies the outline of obstacles by combining clustering and target recognition algorithms.

Key Performance:High measurement accuracy (up to ±3 cm), high resolution (0.2°), wide field of view (supporting 360°×90° stereo scanning), and minimal blind spots.

Notes:Requires a certain level of environmental cleanliness; rainy or snowy weather may affect detection performance.

Application Scenarios:Environments with high cleanliness and high precision requirements, such as industrial robotic arms, indoor overhead cranes, and precision manufacturing workshops; also applicable to outdoor operations in good weather, e.g., port loading/unloading and tower cranes for construction.

Typical Applications:

Anti-collision for the “Linglong One” reactor crane at CNNC:The system accurately detects a 5 cm-diameter steel pipe entering the protected zone.Click for details
