Which gravity conveyor speeds up your line in 2026?

Short answer: For staging and loading, the 18 in x 5 ft roller table with stand is the strongest single buy; folding models like the Threlaco 15 in x 78 in pack away between truck days, and replacement rollers keep any frame running.

Conveyors (2026)

Gravity roller conveyors turn carrying into rolling - packing benches, staging lanes, and truck loading all move faster when boxes glide. The lineup covers steel roller tables and light-duty frames, folding portable units, a 4-meter heavy track, and the 1.5 and 2 inch replacement rollers that fit standard frames.

Which one should you buy?

• Buy the 18 in roller table as the fixed staging and packing lane.
• Buy the Threlaco folding unit for truck-day duty that stores flat after.
• Buy the 4 m heavy track to span dock to trailer nose in one run.
• Buy the 12 in light-duty frame for cartons and totes on a budget.
• Buy replacement rollers before a seized roller becomes the whole line's speed.

How to choose

Gravity means slope discipline

A few degrees moves cartons; more than that launches them. Set fall per foot low, test with your heaviest carton, and guard the discharge end with a stop.

Roller pitch vs carton size

Three rollers under the smallest carton at all times - that is the spacing rule. The 1.5 in rollers on light frames suit totes and cartons; 1.9-2 in steel takes heavier boxes.

Fixed vs folding

Fixed tables anchor a permanent pack station; folding frames earn their price the day the trailer leaves and the aisle comes back.

Hands off moving loads

Pinch points live between carton and roller - push from behind the carton, never brake one from the side, and keep loose cuffs off the line.

Regulatory context

Unpowered gravity conveyors sit under OSHA's general materials-handling and walking-working-surface rules rather than the powered-conveyor standards - the practical duties are guarded ends, controlled slopes, clear aisles alongside, and loads within the frame rating. Every capacity and dimension in the table is the manufacturer's published figure.

Frequently asked questions

What is a gravity conveyor?

An unpowered roller track - loads move by push or slope, no motor. It is the cheapest meters-per-dollar flow equipment a small operation can buy.

How much slope does a gravity conveyor need?

Start near half an inch of fall per foot for medium cartons and tune from there - heavier loads need less, light boxes need a touch more. Test before you commit the line.

How much weight can these hold?

Frame and roller ratings vary by model - the listings publish per-roller or per-frame figures and our table quotes them. Distribute loads; a conveyor is not a shelf.

Can I connect multiple sections?

Yes - matching-width frames butt or hook together; the collocatable light-duty unit is built for exactly that. Keep joints flush so cartons do not catch.

What size replacement rollers do I need?

Measure roller diameter (1.5 and 2 in are the standards here), between-frame width, and axle type - spring-loaded axles drop into standard frames. The roller packs in this lineup cover both diameters.

Gravity or powered conveyor?

Powered belongs to fixed production lines with controls and guarding engineering. For staging, packing, and loading, gravity does the job at one-twentieth the cost - which is why this collection is gravity-only.

Can a conveyor go through a truck door?

That is the classic use - a folding or 4 m section from dock floor to trailer nose, fed by a pallet jack or cart at the back.

Do conveyor lines need guards?

End stops at discharge, clear standing zones alongside, and no reaching across moving cartons - the hazards are pinch points and runaway boxes, both controlled by setup.

How do I clean and maintain rollers?

Keep grit off the line, spin-check rollers monthly, and swap any that drag - one seized roller slows every carton and wears its neighbors. Replacements here cost less than the labor of working around them.

What pairs with a conveyor lane?

Stretch wrap at the end of the line, rated shelving beside it, and tie-downs for what rolls into the truck.
