The Hidden Engineering Power Behind Today’s Road Sweeper Systems

Most people who are passing by a road sweeper silently taking rounds will just know that that is a cleaning machine. Nothing more than sophisticated engineering, however, lies behind the rotating brushes under the rugged chassis. At Nantong Mingnuo Electric Technology Co., ltd., this hidden technology has been honed over the last 20 years. We have grown since we were founded in 2004 as one of the early pioneers in China to become a high tech manufacturer possessing more than 100 patents. Now we would like to draw the curtain aside and see the wonders of the modern sanitation, which is run on by engineering.

The Intelligence of the Integrated Chassis

Contemporary sweeping starts a long time before the brush touches the pavement. It is the design and manufacturing accuracy of a sweeper that makes it powerful. We have modern production lines at our Nantong facilities where all construction stages are monitored. From the first sheet metal weld to the final paint finish, every part is made to be structurally sound. By overseeing the over-all machining, electroplating, and assembly we design chassis which will sustain the strenuous requirements of 24-hour use in the municipal service, so that the vehicle will be stable and dependable even in the most difficult streets of the cities.

The Science of the Airflow System

The airflow of a road sweeper and its filtration system is the most important but non-observable factor that is highly needed. It is not only about vacuuming debris but controlling dust. We have a very active R&D center, which is involved in the aerodynamics in the hopper and the filter. We also make use of the advanced technology in such a way that we collect the large debris, but retain fine particulate matter (PM2.5 and PM10). This eliminates secondary pollution which is a major problem with the older models. We make sure that our engineering processes do not pollute the environment, and that the machine purifies the air just like purifies the streets.

Advanced Manufacturing and Quality Assurance

The correct tools and standards are needed in order to achieve engineering excellence. We have several large-scale equipment stations that are precision-oriented. This enables us to be quick in innovating such as coming up with new waste sorting vehicles and high-performance floor scrubbers. Safety and quality are, however, nothing without raw power. We are also committed to global standards and this can be seen in our certifications such as ISO9001 on quality, ISO14001 on environment management and OHSAS18001 on occupational health. All our products, ranging in size as garbage trucks and all the way down to wash vehicles, have the reliability of this high level of engineering.

Sustainable Power and Global Support

The secret engineering is not limited to the mechanics, but to the core of the machine itself the power source. Being the first in electric sanitation cars, we have invested heavily in the battery technology as well as energy management system. Our electric sweepers will have the power to clean with the strength necessary to tackle the tough chores and the battery life to last an entire day of work, which is achieved through our design of our own batteries and powertrains.

We also know that sanitation departments cannot afford costly downtime. That's why we back our engineering with robust after-sales support. With nearly 100 service centers in over 50 countries, and certifications like CE ensuring compliance, our global team ensures that your equipment performs at its best, day in and day out.

The road sweeper can be found in the welding shop to inside the street of the city, and it is a testament of engineering that is hidden. At Nantong Mingnuo, we are delighted to drive the clean cities of tomorrow with the technology of today.
