Carts and Trolleys — Ergonomics,Capacity and Wheels
Carts & Trolleys — Ergonomics, Capacity & Wheels (Canada)
1) Key cart types & where they fit
- Platform carts (flat deck) — boxes, totes, bulk moves.
- Shelf/service carts — parts picking, tools, bins.
- Hand trucks/dollies — cases, appliances, cylinders.
- Stock carts — narrow aisles; tall shelves.
- Order-picking carts — compartments, label holders.
- Heavy-duty steel — >450 kg loads & rough floors.
2) Ergonomics: handle height & push forces
- Handle height: set around 90–110 cm from floor so elbows are ~90°.
- Push vs pull: push when possible — lower strain and better view.
- Starting force: big wheels (150–200 mm) reduce initial push, especially when loaded.
3) Capacity & frame materials
| Material | Pros | Watch-outs | Typical Capacity |
|---|---|---|---|
| Steel | Strong, repairable | Heavier; paint chips → rust | 450–900+ kg |
| Aluminum | Light, no rust | Cost; weld repairs | 200–450 kg |
| Structural plastic | Quiet, chemical-resistant | Lower max load | 100–300 kg |
4) Wheels/casters: diameter, tread & bearings
- Diameter: 125–200 mm for mixed floors; larger rolls easier over thresholds.
- Tread: thermoplastic rubber (quiet, floor-safe), polyurethane (durable), pneumatic (outdoor/uneven).
- Bearings: sealed precision on high-use; plain bore for washdown.
5) Floor compatibility (concrete, epoxy, tile, outdoors)
- Epoxy/painted: soft TPR/PU to protect coating; avoid steel wheels.
- Tile/VCT: non-marking treads; larger diameter to bridge grout lines.
- Outdoors/docks: pneumatic or soft PU; rust-resistant hardware.
6) Brakes, bumpers & accessories (EN/FR)
- Foot brakes or total-lock casters on slopes and elevators.
- Corner bumpers protect doors and fixtures; add reflective tape for dim areas.
- Bins, peg panels, clipboards, and barcode holders for picking.
- FR/EN: Installer des freins et pare-chocs / Use brakes & bumpers where needed.
7) Cold rooms & winter loading docks
- Use low-temp grease or sealed bearings; avoid brittle plastics below −10 °C.
- Non-slip decks and glove-friendly brakes in ice/snow zones.
- Rinse salt; pick stainless or galvanized hardware where possible.
8) Maintenance checklist
- Monthly: tighten axle nuts, check caster stems/plates, inspect cracks and loose handles.
- Replace flat-spotted or chunked wheels; keep spares on hand.
- Clean decks; remove tape residue to keep loads stable.
9) Common mistakes to avoid
- Undersized wheels on rough floors → high push force and tip risk.
- Overloading shelves → frame twist and caster failure.
- No bumpers in tight doors → constant wall repair.

Important Legal/Compliance Note (Canada)
This page is informational, not legal advice. Manual material handling and cart use fall under provincial Occupational Health & Safety regulations and ergonomics policies. Where standards or site rules specify maximum loads, braking, or aisle widths, those documents prevail. Confirm with your authority having jurisdiction (AHJ) and your internal safety program.
