Application Case | Enhancing Safety and Efficiency: The Role of Laser Scanners in Rail Guided Vehicles (RGVs)
Customer's Background
Zoomlion was founded in 1992 and primarily engages in the research, development, and manufacturing of high-tech equipment such as construction machinery, agricultural machinery, and new building materials. The company's leading products cover 18 major categories, 105 product series, and 636 models. Zoomlion is the first company in the industry to be listed on both the A and H stock exchanges, with a registered capital of 8.678 billion RMB and total assets of 133 billion RMB. Zoomlion was incubated from a national-level research institute and is a standard setter in the industry.
Zoomlion's manufacturing bases are spread across the globe, with 14 domestic industrial parks including Zoomlion Technology Park, Zoomlion Lugu Industrial Park, and others. Internationally, it has several industrial parks including the Italian CIFA Industrial Park, German M-TEC Industrial Park, and more, with plans to establish new factories in Turkey and Saudi Arabia.
In some of Zoomlion's equipment manufacturing industrial parks, many large and heavy workpieces are transported using RGV intelligent rail transfer vehicles. RGV automated rail vehicles, also known as RGV rail guided vehicles, are widely used in logistics systems, featuring high speed, high reliability, and low cost. They can operate on straight or circular tracks, with no limitations on operating distance or time, making them suitable for long-term, high-intensity, and frequent use.
What is Rail Guided Vehicle (RGV)
The RGV rail guided vehicle has a maximum operating speed of 200m/min and can communicate with an upper-level system or WMS. By integrating RFID, barcode, and other identification technologies, it enables automated identification, storage, and retrieval functions. The RGV rail guided vehicle typically uses battery power, rail power, or sliding contact line power, with the choice depending on the vehicle's operating distance. It operates on preset tracks using barcode or laser positioning technology to connect multiple logistics nodes, characterized by high speed, flexibility, simple configuration, and easy maintenance. With the addition of an encoder, the RGV rail vehicle can achieve multi-point docking with minimal error, making it a flagship product for automation in production lines.
Using Rail Guided Vehicles (RGVs)to create a more flexible and efficient production environment
Requirement:
Zoomlion places a high priority on production safety and efficiency. In one of its intelligent equipment manufacturing industrial park workshops, Zoomlion seeks to protect workers from harm caused by moving equipment during the transportation of large or heavy workpieces by RGV rail-guided vehicles. They aim to reduce accident risks and enhance the safety and efficiency of RGV operations.
Solution：
Install DADISICK's LD-20D series safety laser scanner at the front of the RGV rail-guided vehicle. The laser radar is a technology that uses laser pulses for distance measurement. By emitting laser beams and measuring the time taken for the reflection to return, it can accurately determine the position, orientation, and other characteristics of the target.

Advantages for Customer
Enhanced Production Safety: The safety laser scanner can detect and measure the distance to surrounding objects (such as workers, other equipment, or obstacles) in real time, effectively preventing collision accidents. This technology protects workers from moving equipment and reduces accident risks.
Optimized Production Process: Through precise measurement and positioning, the safety laser scanner can help Zoomlion optimize material handling and transportation processes. It ensures that transport equipment stays on the correct track, avoiding deviations or collisions with other equipment, thereby improving production efficiency and accuracy.
Increased Equipment Intelligence: As part of the intelligent sensor system, the safety laser scanner can be integrated with Zoomlion's automated control system to achieve intelligent upgrades to the equipment. Through real-time data feedback and intelligent algorithm analysis, the system can automatically adjust the speed and direction of the transport equipment to adapt to different production needs and environmental changes.
Improved Corporate Image: Zoomlion's choice of your company's safety laser scanner as one of its production safety solutions not only reflects the company's commitment to employee safety and production efficiency but also demonstrates its leadership in technological innovation and intelligent manufacturing. This helps to enhance Zoomlion's corporate image and brand value.
