Automatic Lubrication System Specification Example for Utility Trailers: Heavy Duty
Automatic Lubrication System Specification Example for Utility Trailers: Heavy Duty
This is a worked specification for automatic lubrication system in a heavy duty programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.
The heavy duty version exists because the duty cycle on utility trailers is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually documentation that arrived after the container shipped.
Example specification
| Item | Automatic Lubrication System |
|---|---|
| Application | Utility Trailers |
| Version | Heavy Duty |
| Base material | Cast Iron |
| Controlled dimensions | 5 key dimensions, recorded per lot |
| Tolerance band | ±0.5 mm |
| Finish | zinc plated |
| MOQ | 200 pieces per specification |
| Sampling | 10 working days, 3 days per revision |
| Compliance | SGS |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Cast Iron, in this example.
- List the dimensions that are actually controlled and the tolerance on each.
- Name the finish and what it has to survive.
- State the inspection level and who pays when a lot fails.
Processes involved
- ultrasonic cleaning
- anodising
- injection moulding
- robot welding
- electroplating
- sintering
Where this example applies
Programmes that run heavy duty most often specify this build for utility trailers. Related applications include camper conversions, rental motorcycles, light trucks, agricultural trailers, racing teams.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 2.5 sampling on the finished lot.
- Finish inspection under agreed lighting.
- Carton drop test on the first lot of a new packing specification.
Questions buyers ask
What testing is included?
Standard lots ship with dimensional and hardness reports. SGS documentation is issued with the shipment when your market requires it.
How long does sampling take?
Samples leave the factory in 10 working days, and each revision round adds about 3 days once you have seen the first piece.
Can you match an existing sample?
Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 200 pieces per line.
Share a sample or a drawing and we will quote against a written specification, not against a photograph.
