That pile of iron in your workshop is stuck again, isn't it? Motor humming, belt slipping in place, heavy cargo dead and refused to go forward ... this scene is not particularly familiar? Don't worry, let's break it up and talk about it today--Should I choose a belt line, a doubler chain or a roller line for heavy-duty handling?After reading this, you are guaranteed to stop being fooled by equipment vendors!
First, first understand: what is meant by "heavy load"?
The easiest pitfall for newbies to step into is - thinking that moving a couple of hundred kilos is called a heavy load! In reality:
- light duty: ≤ 500kg (e.g. a box of mobile phone and home appliance casings)
- medium-load: 500-2000kg (car engines, small machine tools)
- True Heavy Duty: ≥ 2 tonnes (steel coil, complete excavator chassis)
Here's the kicker.: If you're moving tonnes of big loads in your workshop, and you're still hardwired to use a belt line...wait for the belts to be changed in three days!
Second, the three major players hardcore PK: who can carry the most?
Directly on the comparison table, even a white person can understand it in seconds:
| comparison term | belt conveyor | Speed Chain Conveyor Line | roller conveyor |
|---|---|---|---|
| Maximum Single Point Load | ≤250kg | ≤4000kg | ≤ 20 tonnes |
| Shock absorption | Weak (belts tear easily) | Medium (steel chain impact resistant) | Strong (steel drum) |
| High Temperature Adaptability | ≤80°C (rubber aging) | ≤600°C (hardened steel chain) | ≤200°C |
| maintenance cost | High (frequent belt changes) | Medium (regular lubrication) | Low (10-year exemption) |
translate into human language::
- leather belt line: Moving cardboard boxes is okay, heavy cargo is a straight pass!
- doubled speed chain: Under 2 tonnes of closed-eye choice, car factories move engines on it
- platen5 tonne coils, 20 tonne machines? Straight up! Mining dock standard.
Third, the actual selection guide: do not worry about the right seat
Scenario 1: Moving engines (1.5 tonnes) in a car factory
Select the multiplier chain!Why?
- The chain bites hard and the workpiece stays in place.
- Speed up to 8 metres per minute. Steady as an old dog.
- add one or twoPneumatic stopperPositioning accuracy ±1mm
lesson learnt through blood and tears: A factory that was not using a belt line to transport engines lost $300,000 when the belt collapsed and shut down production!
Scenario 2: transport of steel coils (5 tonnes) from the logistics warehouse
Roller lines are exclusively customised!Core Operations:
- platenRubber covered non-slip(Friction coefficient↑40%)
- Double chain driveRefuse to slip
- Slope > 10°? AddAnti-Reverse Ratchet!
Scenario 3: delivery of high-temperature parts (500°C+) in foundry workshop
Look directly at the multiplier chain::
- changeHeat-resistant alloy steel chainThe temperature dislikes up to 600℃ without soft feet.
- Don't choose a belt - it turns into "playdough" when it's baked in the heat.
Fourth, the soul torture: my production line should choose who?
Q1: Can I make do with a beltline with a 3 tonne load but on a tight budget?
Don't look for death!To give you the maths:
- Belt line overloading → motor burnt out (20,000 for repairs + loss of production downtime)
- Conversion of drum line ≈ one-time investment of 150,000→I'll lose if I don't get my money back in ten years!
Q2: The speed requirement is 20 metres per minute, can it still carry heavy loads?
Difficulty!Speed vs load is a dead ringer:
- Multiplier chain: For >10 m/min, the load must be cut in half!
- Roller line: recommended ≤ 5 m/min (acceleration under heavy load = suicide)
prescription: Split into two sections of line! The front section feeds at high speed, the back section carries at reduced speed
Q3: What should I do if I always slip in a wet workshop?
Three life-saving moves:
- platen→ WeldingNon-slip pattern(Friction ↑50%)
- doubled speed chain→ UseCeramic Covered Wheel(Running as usual in the rain)
- leather belt lineWhat? Hurry up and change it...
Editor's view
After ten years of production line design, I am afraid that customers will ask for "universal equipment"!There is no such thing as the most pressure-carrying equipment, only the most knowledgeable engineers.--
- Moving an electric enclosure? Multiplier chains are too wasteful, belt lines are sufficient!
- Coil ore? Get on the roller line and don't sweat the difference!
Next time before selecting the type, first to the material over the scale, and then feel the workshop temperature and humidity...With data in hand, the selection is not shaky!
