Only quoting the largest product
The smallest or least rigid base often controls roller pitch and transfer support. The lightest, emptiest or tallest format may control stability and sensing.

Specification control
Record what is known, what is assumed and what still requires a trial.
A useful conveyor specification is not a shopping list of belt width, motor power and frame length. It describes the duty the equipment must perform and the evidence that will show the duty has been met. Keep product data, route dimensions, control interfaces, environment and acceptance criteria in one revision-controlled record so that changes are visible to purchasing, engineering, production and the equipment supplier.
| Specification block | Information to capture | Reason it changes the design |
|---|---|---|
| Product and load | Minimum and maximum dimensions, mass, base condition, centre of gravity, stability, surface and any soft or projecting features. | Controls support surface, width, roller pitch, guides, transfer detail and drive duty. |
| Flow requirement | Target rate, intended pitch, accumulation demand, normal stops, restart conditions and expected format mix. | Separates transport speed from line-control, buffering and release requirements. |
| Route and interfaces | Centreline, infeed and discharge heights, curves, inclines, floor level, neighbouring machines and handover points. | Defines geometry, support, access, guarding boundaries and installation scope. |
| Operating environment | Temperature, moisture, dust, cleaning method, chemicals where known, drainage and working hours. | Influences materials, bearings, electrical protection, access and maintenance planning. |
| Controls and safety | Run permits, blocked and fault signals, modes, speed reference, emergency-stop boundary, isolation and responsible parties. | Prevents gaps between mechanical supply, line control and the project risk assessment. |
| Validation | Representative products, test sequence, measurable acceptance criteria, evidence format and deviation process. | Turns a general expectation into an observable FAT and SAT result. |
Working method
Develop the brief in a sequence that exposes missing information early.
Start with the physical product and actual route, then add the operating sequence and project boundaries. Component selection belongs after those inputs have been reviewed. A motor, belt, chain or sensor chosen before the duty is understood can appear adequate in isolation while failing at a transfer, during accumulation or on a loaded restart.
- Define the product envelopeList every relevant format and identify the smallest base, greatest mass, highest centre of gravity and least stable condition.
- Draw the route and interfacesRecord centreline dimensions, top heights, clearances, operator positions, doors, columns, drains and machine handover points.
- Describe normal and abnormal flowInclude starts, stops, downstream blockage, accumulation, release, fault recovery and manual intervention.
- Set environmental boundariesState cleaning, moisture, dust, temperature, chemical exposure and the maintenance access method.
- Allocate responsibilitiesIdentify who provides supports, guards, wiring, line signals, software changes, installation, conformity work and validation evidence.
- Agree acceptance criteriaUse representative products and observable results rather than unsupported headline speed or reliability claims.
Downloadable input sheet
Use one workbook as the enquiry and design handover record.
The blank CSV separates product, flow, route, environment, interfaces, controls, safety, utilities and validation inputs. It does not calculate or approve a conveyor; it gives the engineering review a consistent starting point and makes unknown items explicit.

Use the site survey checklist for measured site data, the controls integration guide for signal ownership and the FAT and SAT guide for acceptance evidence.
Common omissions
Small missing details often become expensive interface changes.
Giving rate without pitch
Products per minute does not define surface speed unless the intended product spacing is also known. Accumulation and process dwell can further change the requirement.
Ignoring failure and restart states
A line that runs normally may still jam when the downstream machine stops, a sensor is blocked or a loaded incline restarts. These states belong in the brief.
Missing ownership at interfaces
State who provides the mechanical transfer, supports, guarding, isolators, field wiring, software and final validation for the combined line.
Using nominal room dimensions
Confirm actual clearances, floor levels, door swings, access routes and overhead services. A marked-up photograph does not replace measured interface heights.
Uncontrolled sample selection
Identify why each sample is representative. Include difficult formats, normal production variation and the product condition expected during FAT or SAT.
Buyer questions
Conveyor specification workbook FAQs
What information is essential for an initial conveyor quotation?
Provide the product range, dimensions, mass, base condition, target rate, intended route, transfer heights, environment and connected equipment. Mark unknown items rather than estimating them as facts.
Should the buyer specify a motor size?
Normally the buyer should specify the required duty, utilities and operating conditions. Final motor and gearbox selection depends on resistance, load, incline, starts, speed range and the selected components.
How detailed must the layout be?
An initial sketch can establish feasibility, but manufacture and installation require controlled dimensions, top heights, obstacles, access, supports and interface ownership.
What products should be supplied for trials?
Include the smallest and largest formats, the lightest and heaviest condition, the least stable base and any product with flexible, soft or projecting features.
Can one workbook cover a complete line?
Yes, provided it identifies each equipment boundary and interface. Separate schedules may still be needed for controls, safety, utilities and acceptance testing.
Who approves the final specification?
The project should identify authorised technical and commercial approvers. Safety and conformity responsibilities require competent, project-specific decisions rather than approval by a generic web checklist.
