A platform trolley is simple — until you buy the wrong one. The frame looks identical across suppliers; what separates a trolley that runs five years from one that wobbles in six months is three decisions: load rating, deck size, and wheel specification. This guide walks through each with real numbers.
Load capacity: buy for the peak, not the average
The most common buying mistake is matching the trolley rating to the average load. A 200 kg average with a 350 kg Friday peak will destroy a 250 kg trolley. Work from your heaviest recurring load:
| Your peak load | Recommended rating | Typical frame |
|---|---|---|
| 150 kg | 250 kg class | Light platform, 5″ casters |
| 300 kg | 450-500 kg class | Reinforced deck, 6-8″ casters |
| 500 kg+ | 800 kg class | Ribbed HDPE deck on steel frame |
Injection-moulded HDPE decks flex to absorb impact and never rot or splinter like plywood decks. The static versus dynamic load logic we covered for pallets applies here too: a trolley rated 500 kg static may only be rated 350-400 kg rolling.
Deck size: match the footprint, not the door
Measure your most common load first — carton, crate stack, or luggage set — then add 10 cm per side for hand placement and strap routing. Common trap: buying a deck that fits through the door but is too small for the load, forcing two trips that erase the trolley’s purpose.
If you move stackable plastic crates or euro-format boxes, decks sized to 600×800 mm or 800×1200 mm footprints let you build stable loads without overhang. Overhang is the leading cause of load drops in corridors.
Wheels: where trolleys live or die
Wheels are the highest-wear component and the cheapest place to upgrade at purchase:
- Nylon / PP casters — near-indestructible on smooth concrete, noisy and harsh on tile. Best for warehouses and dock work.
- Rubber-tread casters — quiet, floor-friendly, ideal for hotels, hospitals and front-of-house. Slightly lower load per wheel.
- Polyurethane tread — the compromise: high load, moderate noise, resists oil and swarf. Best all-round industrial choice.
- Caster layout — two fixed + two swivel is the stable default; four swivel only for tight-turn spaces like linen rooms.
Wheel diameter is the underrated spec. A 200 mm wheel crosses a dock plate or door threshold almost unnoticed; a 100 mm wheel stops dead and tips the load. For mixed floor conditions, never go below 150 mm on a workhorse trolley.
Handle configuration and fleet logistics
Fixed handles are strongest. Folding or removable handles pay off at fleet scale: empty trolleys nest or stack flat, cutting storage footprint by half and letting a container hold 30-40% more units. If you are importing container loads — as most of our B2B buyers do — folding handles materially change your landed cost per trolley.
Buying checklist
- Peak load + 25-30% headroom = rating to order
- Deck footprint = your load + 10 cm per side
- Wheel material matched to floor (rubber front-of-house, PU industrial, nylon warehouse)
- Minimum 150 mm wheels for threshold-heavy routes
- Folding handle if storage space or container packing matters
- Spare casters quoted with the order — the first thing to wear is the cheapest thing to stock
