Supports various parts of the conveyor, ensuring stable operation. Height is adjustable to create horizontal or inclined conveying surfaces. Its load-bearing capacity must exceed the combined weight of the conveyor components and conveyed items to ensure safe system operation.

Common materials include steel, aluminum alloy, wood, and plastic. Steel supports are high-strength and impact-resistant, suitable for heavy industrial applications. Aluminum alloy supports are lightweight and corrosion-resistant, commonly used in food and pharmaceutical industries. Wooden supports are low-cost and easy to process, suitable for light loads or temporary systems. Plastic supports are water-resistant and chemically resistant, often used in special environments.

Structures include C-shaped steel, square/rectangular tubing, and truss structures. C-shaped steel is an open structure, easy to install and adjust. Square/rectangular tubing is a closed structure with strong torsional resistance, suitable for long-span support. Truss structures distribute loads and reduce resonance during long-distance conveying.

Based on mobility: Fixed supports are typically bolted to the ground for stable support; mobile supports are equipped with casters for easy movement, suitable for temporary or frequently repositioned applications.
Based on application: Standard supports are used for general support; driven supports add a support structure at the drive end to ensure the stability of the drive section.

These include the support's span, height, and load-bearing capacity. The support span is related to the load and must be designed based on specific load parameters and allowable material stress to ensure the support's strength and stability.
