Road sweeping machines are construction vehicles that mechanically perform surface cleaning in urban and intercity road networks, airport runways, and industrial facility sites. These machines are used for purposes such as ensuring environmental hygiene, suppressing dust, collecting waste, and improving occupational health and safety.

History and Early Areas of Use

The development of street sweeping machines dates back to the mid-19th century, when urbanization accelerated after the Industrial Revolution. The first recorded sweeping device was a horse-drawn mechanical broom developed in 1843 by Joseph Whitworth in Manchester, England. This machine used rotating brushes to collect dust and debris from streets and marked a significant milestone in the hygiene practices of the time.

Later, in the 1860s, as the need for street cleaning grew in large U.S. cities such as Philadelphia and New York, manual brooms became insufficient. As a result, mechanization progressed and sweeping carts were developed. In 1870, the first patented motorized sweeper was invented. Although still horse-drawn, these machines featured brush systems powered by motors, enabling more systematic cleaning.

In 1911, the first fully motor-powered road sweeping machine was introduced in the United States. From that point on, vacuum systems and water-spraying technologies were integrated into the machines to suppress dust and improve cleaning efficiency. From the mid-20th century onwards, sweeping machines were equipped with diesel engines, becoming autonomous cleaning vehicles. Today, they are being designed with electric, hybrid, or low-emission engines to enhance environmental sustainability.

Types of Road Sweeping Machines

Technical Structure and Functional Components

According to the MEB (Ministry of National Education) Construction Machinery Module, road sweeping machines are classified as special-purpose machinery equipped with mechanical cleaning functions. Their main systems include:

• Brush and Sweeping Mechanism: Typically consists of front and side brushes that direct solid and dust particles toward a central vacuum or conveyor system.
• Vacuum System: Ensures suction of waste guided by the brushes; critical for dust collection and suppression.
• Water Spray Unit: Works alongside the brushes to prevent dust formation and increase cleaning efficiency.
• Waste Container (Storage Unit): The compartment where swept and vacuumed debris is stored. It is usually emptied using a hydraulic system.
• Hydraulic System: Powers various functions such as brush movement, vacuum control, and hopper door operations.
• Cabin and Control Panel: The operator manages the machine from here. Modern cabins include ergonomic seats, air filtration systems, and digital displays.

These components can be configured differently depending on surface types and environmental conditions. In major cities, machines are equipped with high-capacity water tanks and advanced maneuvering capabilities.

Areas of Use and Operational Principles

Road sweeping machines are widely used in the following areas:

• Municipal cleaning services
• Industrial site cleaning (factories, ports, industrial zones)
• Shopping mall and parking lot floor cleaning
• Airport apron and runway cleaning
• Highway and urban road networks

These machines are typically operated in the early morning or late at night to avoid disrupting traffic. During operation, attention must be paid to environmental emissions, noise levels, and waste management.

Operator Training and Certification Process

According to the Ministry of National Education Operator Guidelines, individuals operating road sweeping machines must possess an operator certificate issued by authorized training centers. The training process includes:

• Theoretical Training: Covers machine classification, technical specifications of road sweeping machines, occupational health and safety, environmental impacts, traffic regulations, and daily maintenance.
• Practical Training: Candidates perform sweeping, dumping, maintenance, and fault detection tasks on actual machines.
• Evaluation and Certification: Candidates take theoretical and practical exams at the end of the course. Those who pass receive a “Construction Machinery Operation Certificate,” which is valid only for the specific type and class of machine.

According to the guidelines, operator training must be conducted at MEB-approved institutions and follows a modular curriculum. The use of personal protective equipment (gloves, vests, goggles, etc.) is also mandatory during training.

Occupational Health and Safety

Due to the presence of moving parts, road sweeping machines pose various physical hazards. Therefore:

• Daily maintenance and fault inspections must be carried out before use.
• During operation, protective equipment such as seat belts, noise-insulating ear protection, and reflective vests must be worn.
• The water spray and vacuum systems must operate at full capacity to prevent dust dispersion.

According to the MEGEP module, these machines must undergo periodic inspection every six months and be properly recorded.
