How to Choose a Double Speed Chain Conveyor
A Practical Buying Guide for Manufacturers to choose a double speed chain conveyor
In modern assembly production lines, the double speed chain conveyor (also called double speed assembly line) is widely used in automotive parts, electronics, home appliances, and machinery industries.
However, many buyers face one key question:
👉 How do I choose the right double speed chain conveyor for my production line?
This practical guide will help you evaluate, compare, and select the most suitable system based on real production needs.
What Is a Double Speed Chain Conveyor?
A double speed chain conveyor is a modular conveying system that uses a special chain structure where the pallet runs at twice the chain speed. It allows:
Flexible station layout
Accumulation and buffering
Independent workstation operation
High-efficiency assembly flow
It is suitable for manual , semi-automatic and full-automatic assembly lines.
1️⃣ Clarify Your Production Process
Before choosing a model, you must clearly define your production requirements.
Ask Yourself:
What product am I assembling?
What is the product size and weight?
What is the production capacity per hour?
Is the line manual, semi-automatic, or fully automatic?
Do I need buffering between stations?
Is there inspection and testing equipment, screwing, labeling, or robotic machine integration?
Why This Matters
The structure, chain size, motor power, and pallet specification all depend on:
Product load
Cycle time
Line length
Number of stations
⚠️ Many buyers focus only on price, but process clarity is the real foundation of correct selection.
2️⃣ Choose the Right Load Capacity
Different double speed chains have different load capacities.
Common models:
60 type
80 type
100 type
General Reference:
| Model | Typical Load per Pallet | Application |
| 60 | Light products (≤30kg) | Electronics, small parts |
| 80 | Medium load (30–80kg) | Auto parts, appliances |
| 100 | Heavy load (80kg+) | Machinery components |
If your product weight is underestimated, the chain may:
Wear quickly
Produce vibration
Reduce lifespan
✔ Always consider both product weight + fixture weight.
3️⃣ Determine Line Layout Structure
Double speed chain conveyors support various layouts:
Straight line
L-shape
U-shape
Rectangle loop
Multi-layer return structure
Selection Tips:
Small workshop → U-shape saves space
Long process with many stations → Straight or loop type
Need continuous circulation → Closed-loop design
This is a Rectangle loop layout.
Space planning is critical. Provide your supplier with:
Workshop layout drawing
Power supply location
Air source position
4️⃣ Decide on Pallet Type and Size
Pallet selection affects:
Stability
Positioning accuracy
Fixture installation
Future product compatibility
Key factors:
Product base size
Need for anti-static?
Need RFID?
Need lifting or rotation mechanism?
✔ Choose a pallet slightly larger than the product base to allow fixture flexibility.
5️⃣ Evaluate Speed & Production Capacity
Cycle time calculation example:
If your target output is 120 units/hour:
Each unit = 30 seconds
Station quantity must match rhythm
Conveyor speed must match takt time
Adjustable speed motor is recommended.
✔ Suggestion: Choose frequency control motor (VFD) for flexible adjustment.
6️⃣ Consider Automation Integration
Modern double speed assembly lines often integrate:
Screw tightening machines
Vision inspection systems
Barcode scanning
Robotic loading/unloading
Testing equipment
So you must check:
Is the frame strong enough for automation modules?
Are electrical interfaces reserved?
Is the control system expandable?
A future-upgradable line saves long-term investment cost.
7️⃣ Safety & Ergonomic Design
Do not ignore safty guarding system:
Emergency stop buttons
Safety covers
Anti-pinch design
Operator working height
Noise level
For overseas markets, check compliance:
CE standard
ISO requirements
Electrical safety regulations
8️⃣ Material & Structural Quality Comparison
Aluminum Profile vs Steel Structure
| Feature | Aluminum Structure | Steel Structure |
| Weight | Light | Heavy |
| Installation | Modular & flexible | Welding required |
| Maintenance | Easy replacement | More complex |
| Cost | Slightly higher | Lower initial cost |
For flexible assembly lines, industrial aluminum structure is more recommended.
9️⃣ Choose Standard vs Non-Standard Customization
Standard model may be cheaper, but:
May not match your process perfectly
Limited expansion
Low efficiency improvement
Non-standard customization advantages:
Designed according to real workflow,flexible connection with automated assembly equipment
Higher efficiency
Better ergonomic design
Future expansion reserved
For growing manufacturers, customized solutions are usually more cost-effective in the long run.
🔟 Evaluate Supplier Capability
Before choosing a supplier, check:
Years of manufacturing experience
In-house design team?
In-house production workshop?
Past industry cases?
Overseas export experience?
After-sales service support?
A reliable supplier should provide:
2D / 3D layout drawings
Load calculation
Electrical diagram
Installation guidance
Debugging support
Common Mistakes When Choosing Double Speed Chain Conveyor
❌ Only comparing price
❌ Ignoring future production expansion
❌ Not calculating real load
❌ No communication of actual process flow
❌ Choosing underpowered motor
Final Checklist Before Purchase
✔ Product weight confirmed
✔ Production capacity calculated
✔ Layout drawing ready
✔ Future automation considered
✔ Supplier technical proposal reviewed
✔ Safety standard confirmed
