Supports the various parts of the conveyor ensuring stable operation. Height is adjustable to create horizontal or inclined conveying surfaces. Load-bearing capacity must exceed the combined weight of 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 for heavy industry; aluminum alloy is lightweight and corrosion-resistant for food & pharma; wooden supports suit light loads or temporary systems; plastic supports resist water and chemicals for special environments.

Available in C-shaped steel, square/rectangular tubing, and truss structures. C-shaped steel is an open structure easy to install; square/rectangular tubing is closed with strong torsional resistance for long-span support; truss structures distribute loads and reduce resonance during long-distance conveying.

By mobility: Fixed supports (bolted to ground) vs. Mobile supports (caster-equipped for easy relocation). By application: Standard supports for general use vs. Driven supports that reinforce the drive end for enhanced stability of the drive section.

Key parameters include span, height, and load-bearing capacity. The support span is determined by load requirements and must be designed based on specific load values and material allowable stress to ensure adequate strength and stability.
