Supports various parts of the conveyor to ensure stable operation. It offers adjustable height to form a horizontal or inclined conveying surface. Its load-bearing capacity must exceed the combined weight of the conveyor components and the conveyed items to ensure safe operation.

Common materials include steel and aluminum alloy (along with wood and plastic for lighter/special uses). Steel supports are high-strength and impact-resistant, suitable for heavy industrial applications. Aluminum alloy supports are lightweight and corrosion-resistant, commonly used in the food and pharmaceutical industries.

Available in C-shaped steel, square/rectangular tube, and other structures. C-shaped steel is an open structure facilitating installation and adjustment. Square/rectangular tubes are closed structures offering strong torsional resistance, ideal for long-span support. Truss structures are also used to distribute loads and reduce resonance during long-distance transport.

Fixed supports are typically bolted to the ground for stable, permanent positioning. Mobile supports are equipped with casters for easy movement, suitable for temporary or frequently repositioned applications. Based on application, they are also divided into standard supports for general use and driven supports that add stability to the drive section.

Key parameters include span, height, and load-bearing capacity. The span of the support is closely related to the load and must be engineered based on specific load weights and allowable material stress parameters to guarantee structural strength and long-term stability.
