They are often used in processes that require constant lifting or lowering of products, such as transferring materials to different levels of a production line or loading and unloading at different levels.

Special conveyors

Some industrial operations have specific requirements and need custom-built conveyors. Special conveyors are designed to meet these unique demands, whether through specific materials, custom dimensions or unique features that meet the customer's needs exactly, ensuring maximum efficiency and fit with the process.

2. Roller conveyors

Roller conveyors are sturdier and ideal for conveying heavy loads. They use rollers arranged in series to support and convey the materials. Depending on the application, these conveyors can be configured in different ways:

Gravity roller conveyors

This type of conveyor operates without a drive, allowing materials to move by gravity or be pushed by hand. They are ideal for environments where flow control is not critical, such as storage areas or assembly lines where products need to be moved by hand over short distances.

Powered roller conveyors

Equipped with powered rollers, these conveyors offer precise control over the movement of heavy materials. They are particularly useful in automated processes, where conveying speed and direction need to be regulated to ensure continuous, efficient flow, as in high-volume production lines.

Curved roller conveyors

Designed to change the direction in which materials are conveyed, curved conveyors are essential in industrial facilities where space is limited or the layout requires changes of direction. They allow smooth, continuous movement of materials around curves, without compromising conveying speed or stability.

Flexible/extendable conveyors

Flexible or extendable conveyors are highly adaptable, designed to fit different layouts and distances as needed. They can be extended, retracted and adjusted in shape and length, which makes them ideal for dynamic work environments, such as logistics centers and factories that need conveying solutions that can be quickly set up for different tasks. These conveyors are especially useful where space is limited and flexibility in moving materials is essential to maintain operating efficiency.

Main components

Belt

The surface on which materials are conveyed; it can be made of rubber, PVC, metal and other materials.

Structure

The base that supports the belt and the other components.

Gearmotor
