Supports all conveyor parts ensuring stable operation. Height-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.

Steel: High-strength, impact-resistant — ideal for heavy industrial use.
Aluminum Alloy: Lightweight, corrosion-resistant — common in food & pharma.
Wood: Low-cost, easy to process — suitable for light loads or temporary systems.
Plastic: Water & chemical-resistant — used in special environments.

C-shaped steel: Open structure, easy to install and adjust.
Square/Rectangular tubing: Closed structure, strong torsional resistance, ideal 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 (with casters for easy repositioning).
By Application: Standard supports (general support) vs. Driven supports (reinforced at drive end for stability).

Key parameters 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 values and material allowable stress parameters to ensure the support's overall strength and stability.
