Demag wheel block, with its excellent performance and high load capacity, has become an ideal solution for heavy-duty automatic guided vehicle (AGV) applications. In the context of the Industrial 4.0 era, heavy-duty AGV has become indispensable intelligent transportation equipment in heavy manufacturing, port logistics, warehousing, aerospace, and other fields. This type of equipment needs to meet the extreme load requirements of 10-100 tons, and at the same time faces multiple tests such as complex ground conditions, high-frequency start and stop, and precise positioning. Traditional travel units often cause downtime accidents due to metal fatigue, bearing failure, or drive system overload, which directly threatens production continuity.

Technical breakthroughs of Demag wheel block system

• Super load-bearing design

Demag wheel block systems adopt a series of innovative designs, which give them the super load-bearing capacity and can cope with the working requirements of heavy-duty AGVs under extreme working conditions. The static load-bearing capacity of the wheel set is up to 180 tons/group, ensuring that the AGV can operate stably in an environment with a load of up to tens of tons. The wheel body material is GGG70 ductile iron, which has higher toughness and fatigue resistance than traditional steel, and its fatigue life is increased to 3.2 times that of conventional products, effectively reducing the risk of failure caused by long-term operation.

In addition, the V-shaped flange design of the Demag travel wheel block can effectively reduce contact stress and reduce the risk of track collapse by 37%, ensuring that the wheel range can still run smoothly under high load, reducing wear on the track and extending the service life of the track.

• Intelligent drive wheel block system

In order to improve the power efficiency of AGV, Demag wheel set adopts a combination of integrated variable frequency motor and planetary reducer, with an output torque range of 1800-6500Nm, which can adapt to various high-load conditions. The drive system has a high transmission efficiency of 94%, which is 21% energy-saving compared to the traditional chain drive system. This optimized design not only improves the power performance of AGV, but also reduces power consumption and extends battery life.

In addition, the Demag wheel box is also equipped with a torque limiting device that can respond to overload conditions within 5 milliseconds to avoid mechanical damage caused by overload in time. This intelligent protection mechanism significantly improves the operating safety and reliability of the AGV and reduces maintenance costs.

• Enhanced environmental adaptability

AGVs often face various harsh environments during use, including extreme working conditions such as dust, oil, moisture, and high or low temperatures. Industrial drive wheel ranges have made special enhancements in environmental adaptability to ensure that they always maintain excellent performance in complex working environments. Its IP67 protection level can effectively prevent the intrusion of external pollutants such as dust and oil, and can withstand high-pressure washing to ensure the cleanliness and stable operation of the internal parts of the wheel block.

In addition, the Demag wheel block is also equipped with a temperature-controlled lubrication system that can work stably in an extreme temperature range of -30°C to +80°C, greatly improving the adaptability of AGVs in cold or hot environments, ensuring that they can maintain excellent operating performance under various temperature conditions.

• Modular design and fast maintenance

The modular design of high-quality universal travel wheel system enables each key component to be replaced or repaired independently. This design makes on-site maintenance more efficient, and the MTTR (mean time to repair) is shortened to 45 minutes, greatly improving the operational efficiency of AGV. In addition, the modular design also supports the rapid replacement of different components of the wheel block on site, reducing maintenance costs and downtime, and providing a solid guarantee for the efficient operation of the AGV system.

With the continuous improvement of industrial automation and intelligence, the role of AGV in heavy-duty transportation is becoming more and more important. Heavy Loads travel wheel systems have become an ideal solution for heavy-duty AGV applications with their excellent performance, high load capacity, intelligent drive system and strong environmental adaptability. Whether in manufacturing, logistics, aerospace and other fields, Demag wheel blocks can provide stable and reliable support for AGV systems, helping the industry to achieve more efficient and safe transportation operations.
