Positioning control of heavy load transport overhead cranes with retrofitted laser distance sensors.
When transporting heavy objects, use a laser distance sensor instead of an encoder to measure and control the positional information on the X-axis/Y-axis within 50-100m.
When transporting heavy objects over a distance of 50-100m, using encoders can lead to slippage, resulting in cases where accurate positioning is not possible. While it would be ideal to implement a mechanism that prevents slippage, it can be costly and inefficient. In such cases, an increasing number of users are employing laser distance sensors to measure positional information and control the crane's motor. This also eliminates the risk of collisions between cranes. The system operates at temperatures as low as -40°C, making it suitable for use in cold storage warehouses. With a measurement accuracy of 1mm, a repeatability of 0.3mm, and a measurement speed of 250Hz (maximum), sufficient positioning accuracy can be achieved for crane motor control. This eliminates the need for mechanisms to suppress slippage, resulting in a cost-effective system. This laser distance sensor is useful for transporting heavy objects and for use in cold storage warehouses. Our company provides comprehensive technical support, including usage guidance, implementation, control software development, and post-installation support.

Company information
Since its establishment, we have been involved in the development of our own products, starting from gathering ideas, and have repeated the processes of mechanical design, processing, circuit design, and embedded programming every year. Currently, we are engaged in both OEM production and the sale of our own products, and we intend to continue developing measuring instruments that can further meet our customers' needs. We are also the general agent for Dimetix in Switzerland and are focusing on the sales of red laser distance meters. This product has been adopted for measuring the height of the Tokyo Skytree, the tallest structure in the world. We believe there are still many applications for this technology, and we would like to explore each one. In recent years, we have also been focusing on measuring instruments for railway-related construction limits. We have started to receive inquiries from East Japan Railway Company regarding the development of measuring instruments for construction limits in various fields such as construction, civil engineering, signaling, and power. Additionally, we received an Encouragement Award at the 28th Ota City Small and Medium Enterprises New Products and New Technologies Competition for our graphic-integrated construction limit measuring instrument.
