Carts & Trolleys in Canada
Carts & Trolleys — Ergonomics, Capacity & Wheels (Canada)
1) What types of carts/trolleys are common?
- Platform carts — flat deck + one/two handles; general freight.
- Shelf/utility carts — 2–3 shelves; picking, kitting, housekeeping.
- Service/linen carts — hospitality/healthcare.
- U-boats — long narrow deck for retail replenishment.
- Hand trucks/dollies — stair, appliance, convertible 2-in-1.
2) How do I size capacity (kg) safely?
| Use Case | Typical Load | Target Capacity |
|---|---|---|
| Light picking / office | 50–120 kg | 150–250 kg |
| Warehouse general | 150–300 kg | 300–500 kg |
| Heavy duty / docks | 300–600 kg | 600–1000 kg |
Capacity is only as good as the casters and frame. If your floor has joints/ramps, step up rating and wheel diameter.
3) Which wheel/caster should I pick for my floor?
| Wheel Material | Best For | Pros | Watch-outs |
|---|---|---|---|
| Thermoplastic rubber (TPR) | Indoor smooth floors | Quiet, floor-friendly | Lower load than PU |
| Polyurethane (PU) | Warehouses, mixed floors | High load, low rolling resistance | Can be noisy on rough concrete |
| Rubber | Outdoor ramps, thresholds | Grip, shock absorption | Higher push force |
| Pneumatic / semi-pneumatic | Uneven outdoor, gravel | Excellent shock isolation | Less precise, larger turning radius |
Bearings: Sealed precision ball bearings roll easier and last longer in wet/salty environments.
4) Ergonomics: handle height, push forces, and aisles.
- Handle height: typically wrist height of primary users (~90–110 cm from floor).
- Push force: keep initial push under ~23 kgf for heavy loads; larger wheels help.
- Aisles: allow turning radius; long U-boats need wider ends or 2-swivel/2-rigid caster mix.
5) Deck materials: steel, aluminum, plastic — pros/cons.
- Steel — strongest, best for docks; powder-coat or galvanized for rust.
- Aluminum — lighter to push, corrosion-resistant.
- Plastic (HDPE) — quiet, chemical-resistant; lower max load.
- Deck tops: anti-slip mats, ribbed surfaces, or wire for drainage.
- Edges: lips keep boxes; flat edges ease side-loading.
6) Two-shelf vs three-shelf vs platform — what’s best?
- Two-shelf: taller items, quicker access.
- Three-shelf: small parts, tools, kits.
- Platform: bulk cartons, appliances, irregular items.
7) Brakes, bumpers, guards & noise control.
- Brakes: total-lock casters for ramps/elevators.
- Bumpers: corner rubber to protect walls and corner guards.
- Noise: TPR wheels and mat-lined shelves cut rattle.
- Guards: vertical rods or nets prevent box fall-off.
8) Cold rooms, outdoors & winter ramps (EN/FR).
- Use sealed bearings and stainless hardware in wet/salt areas.
- Rubber or PU wheels grip better on cold smooth floors.
- FR/EN: Choisir des roues adaptées au froid et au sel / Choose cold- and salt-ready wheels.
9) Inspection & maintenance checklist.
- Monthly: check caster forks, axle nuts, bearings, and deck cracks.
- Replace flat-spotted or chunked wheels; lube where specified.
- Tag-out damaged carts; don’t keep “mystery squeakers” in service.
10) Recommended bundles & add-ons.
- Edge guards/boards to protect cargo.
- Stretch wrap & tape for secure loads.
- Convex mirrors at blind cross-aisles.
- Wheel stoppers in loading bays.
- Posts & chains to guide pedestrian paths.
- Corner guards to protect pillars.
Important Legal/Compliance Note (Canada)
This guide is informational, not legal advice. Manual material handling and cart use fall under provincial Occupational Health & Safety requirements (ergonomics, ramps, brakes, PPE). Where company policy, OHS regulations, or building/fire codes specify equipment or limits, those rules prevail. Consult your safety officer or the authority having jurisdiction (AHJ) for site-specific requirements.
