Conveyor Support — 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 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.
🧱 Materials
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.
🔧 Structural Forms
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.
🗂️ Types
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
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.
❓ Frequently Asked Questions
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 chosen depends on the material being conveyed, conveyor belt width, and the load requirements of the system.
Q
What materials are commonly used for conveyor supports?
Common materials include steel, aluminum alloy, wood, and plastic. Steel is preferred for heavy industrial use due to its high strength; aluminum alloy is popular in food and pharmaceutical applications for its light weight and corrosion resistance; wood suits light or temporary setups; plastic works well in chemically harsh environments.
Q
What surface treatment is required for conveyor bracket steel parts?
Steel conveyor brackets must undergo rust prevention treatment, typically through hot-dip galvanizing or spray coating. These treatments protect the metal from corrosion, extending the service life of the support structure significantly.
Q
What is the difference between fixed and mobile conveyor supports?
Fixed supports are bolted directly to the ground, offering maximum stability for permanent conveyor installations. Mobile supports are fitted with casters, allowing them to be repositioned easily — ideal for temporary setups or applications where the conveyor layout changes frequently.
Q
Which international standards apply to conveyor roller brackets?
The primary international standards are ISO 1537:2018 "Continuous Mechanical Handling Equipment" and the DIN 22112 "Belt Conveyor" standard system. These provide guidelines for dimensional specifications, material requirements, and performance benchmarks for conveyor supporting components.
Q
How should I choose the right size roller bracket for my conveyor?
Since bracket dimensions vary across manufacturers and product models, it is strongly recommended to consult a professional belt conveyor manufacturer or supplier. Provide details such as conveyor belt width, load capacity, conveying distance, and operating environment to receive the most accurate size recommendation.
