In recent years, eco-friendly conveyor belts have gained traction, powered by solar energy or crafted from recycled materials. Additionally, smart technology and modern advancements are driving the evolution of conveyor belts, with computerized systems enhancing efficiency and functionality.

To ensure durability and longevity, conveyor belts are often treated with weatherproof coatings. These coatings safeguard the belts from environmental factors, such as moisture and temperature variations, which could otherwise compromise their integrity and lead to operational disruptions. By investing in durable materials and weatherproofing techniques, airport operators can minimize the risk of conveyor belt failures and maintain the smooth flow of baggage handling operations.

The choice of belting material is critical, as the wrong material could hinder productivity or pose safety hazards. Therefore, careful consideration is given to selecting the most suitable material for each application, taking into account factors such as flexibility, strength, and resistance to wear and tear.

The belts are supported by rollers to keep objects in place and prevent sagging

Conveyor belts are designed to increase efficiency and speed up processes, especially when dealing with a large number of orders. They are used in various industries, including airports, warehouses, and construction sites, to transport materials and products quickly and efficiently.

At airports, conveyor belts play a crucial role in baggage handling processes. They help move baggage from check-in to the baggage handling system and then to the proper terminal. These belts are typically made of robust fabrics with weatherproof coating materials to ensure reliable conveying and prevent disruptions.

The rollers also play a crucial role in keeping objects stable and secure during transportation. By preventing sagging, the rollers minimize the risk of objects shifting, falling, or rolling back on the belt. This stability is particularly important in airport settings, where baggage comes in various shapes and sizes, and the smooth operation of the conveyor system is essential for efficient baggage handling.

Furthermore, the rollers enable the conveyor belt to operate at a constant speed, which is crucial for effective baggage screening at airports. By maintaining a consistent speed, the rollers help ensure that the belt tracks in a straight line through X-ray equipment, preventing shadows that may obscure the X-ray image.
