🏗️ Conveyor Supports — Detailed Overview
Conveyor supports are a crucial component of conveyor systems, used to support and secure the various parts of the conveyor, ensuring stable operation.
⚙️ Function
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.
🧱 Materials
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.
📦 Structural Forms
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.
🔀 Types
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
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.
❓ Frequently Asked Questions (FAQ)
Q
What is the standard installation angle for groove type roller groups?
The standard installation angle for groove type roller groups is typically 30° or 35°. The specific angle selected depends on the material being conveyed and the belt width, and should be confirmed with the conveyor manufacturer before installation.
Q
What materials are conveyor supports commonly made from?
Conveyor supports are commonly made from steel, aluminum alloy, wood, and plastic. Steel is preferred for heavy-duty industrial applications due to its high strength; aluminum alloy is popular in food and pharmaceutical industries for its light weight and corrosion resistance; wood is suitable for light or temporary systems; and plastic is used in chemically aggressive environments.
Q
What surface treatments are recommended for conveyor brackets?
The two primary surface treatments are hot-dip galvanizing and spray coating (painting). Hot-dip galvanizing offers superior long-term rust protection especially in outdoor or humid environments, while spray coating provides both corrosion resistance and a cleaner aesthetic finish for indoor applications.
Q
What is the difference between fixed and mobile conveyor supports?
Fixed supports are bolted directly to the floor, providing maximum stability and load-bearing capacity — ideal for permanent conveyor installations. Mobile supports are fitted with casters, allowing the conveyor to be repositioned easily, making them suitable for temporary setups or applications that require frequent layout changes.
Q
Which international standards apply to conveyor bracket design?
Key international standards include ISO 1537:2018 ("Continuous Mechanical Handling Equipment") and the DIN 22112 ("Belt Conveyor") standard system. These provide reference guidelines for structural dimensions, materials, load capacities, and safety requirements for conveyor bracket design and manufacturing.
Q
How do I choose the right size of roller bracket for my conveyor system?
While standard dimension references (such as 1200–1500 mm center distance for flat roller groups) serve as a starting point, the correct roller bracket size depends on factors including belt width, conveyed material weight, span length, and load-bearing requirements. It is strongly recommended to consult a professional belt conveyor manufacturer or supplier to select the most appropriate bracket specifications for your specific application.
