Platform size decides whether the load sits on the trolley at all, and it is the figure to settle before capacity. A load that overhangs is unstable however far the capacity figure exceeds its weight, because the trolley tips on the axle rather than failing under load. Deck height also decides how far a load has to be lifted before it is on the trolley at all.
Capacity then follows, at 80kg on the foldable cart through 150kg and 300kg on the platform trolleys and up to 2.5 tonne on the pallet trucks. Pallet trucks are a different machine, lifting a pallet on forks rather than carrying a load on a deck. Pallet trucks also need a pallet, which a platform trolley does not, so the load form decides between them.
Wheel type decides where the trolley will actually go. Small hard wheels roll easily on smooth concrete and stop dead at a threshold or a cable. Large wheels cross rough ground and a yard, at the cost of a higher deck and more effort to steer. An interlocking plastic dolly at 150kg covers moving a load short distances on a flat floor.
Removable sides turn a flat platform into a container so loose items do not slide off, and a canvas folding trolley at 70kg collapses when empty. Beam clamps and a gantry beam trolley are seated on the leaf.
