Buying a shopping trolley: what to look for in load capacity, wheels and folding features

A shopping trolley can make it much easier to transport groceries, drinks, laundry or parcels. However, models vary considerably in load capacity, weight, wheel design and weather protection. If you focus only on a large bag or a low price, you could overlook important details.

The most common problems when buying one come down to three typical pitfalls:

  1. Unclear load capacity: The stated weight limit does not always clearly apply to the bag, frame or converted hand truck.
  2. Overstated weather protection: “Water-resistant” does not automatically mean waterproof. In heavy rain, moisture can get in through seams, zips or the opening.
  3. Unsuitable wheels: Two large wheels are suitable for pavements and trips around the supermarket. A six-wheel shopping trolley is designed quite differently to handle kerbs and stairs.

Key things to consider when buying a shopping trolley

1. Load capacity and actual weight

First, check how much weight the trolley can carry and how heavy it is. A lightweight shopping trolley weighing 1.15 kg is easy to lift into a car or carry up a few steps. However, the hand-truck function on this model is limited to 20 kg.

A higher load capacity can be useful for crates of drinks, parcels or moving boxes. A folding shopping trolley with a detachable bag can often be used as a folding sack truck or hand truck. What matters is whether the manufacturer gives the load capacity for the frame or for the complete bag.

Also look for a stable base, an even weight distribution and a handle that suits your height. A high load capacity does not make the trolley safe to handle on sloping ground.

2. Wheel type and suitability for stairs

A traditional shopping trolley with two EVA wheels usually rolls smoothly on pavements, paving and indoors. However, this design has its limits when it comes to high kerbs or stairs.

A stair-climbing shopping trolley usually has three rotating wheels on each side. This allows it to move step by step over edges. The design makes it easier to tackle stairs, but you still need to pull it carefully and load it evenly. Always follow the safety instructions for the product when using it on stairs.

A trolley with a brake or lockable wheels can be more practical at bus stops, on ramps or when loading. If you have a basic folding shopping trolley without a brake, don’t leave it unattended on a slope.

3. Bag, folded size and material

A shopping bag on wheels is practical for everyday use when its capacity and accessibility suit the way you shop. A capacity of 20 to 30 litres is often enough for a daily shop. If you’re looking for a shopping trolley with a large bag for your weekly shop, consider the strength of the bag’s base as well as its capacity.

Several models list 600D Oxford polyester as a hard-wearing bag material. A water-resistant coating helps protect against light rain and splashes. Even so, check claims that a shopping trolley is waterproof carefully: without specific information about seams, fastenings and prolonged exposure to wet conditions, “water-resistant” is the more accurate description.

A folding shopping trolley should fit in your boot, behind a door or in a storage cupboard when folded. So check the folded dimensions as well as the size when it’s open.

Frequently asked questions about shopping trolleys

How many litres should a shopping trolley hold?

For smaller shops, 20 to 25 litres is often enough. Models with a capacity of 30 to 38 litres are more practical for families or a weekly shop. The usable capacity also depends on the lid, internal compartments and the shape of the bag.

Are six-wheel shopping trolleys suitable for every staircase?

No. A six-wheel shopping trolley is designed to handle kerbs and steps more easily than a two-wheel model. However, the width of the stairs, step height, load and your own strength all matter. Pull the trolley slowly and follow the instructions.

How do you care for a folding shopping trolley?

Regularly remove sand, hair and dirt from the wheels and joints. The bag can usually be cleaned with a damp cloth. Store the trolley somewhere dry, and only fold it away once the fabric is thoroughly dry. Before carrying a heavier load, check the screws, axles and folding mechanism.
