Buying a shopping trolley: what to look for in load capacity, wheels and storage space

A shopping trolley should reliably carry groceries, laundry, parcels or crates of drinks. In practice, however, some models disappoint because key details are unclear: the stated load capacity may apply only to the frame, the storage space may be smaller than expected, or the wheels may not be suitable for cobbled streets and stairs.

Check these three common pitfalls before you buy:

• Don’t confuse load capacity with bag volume: A shopping trolley described as holding 25 kg may refer to the frame’s maximum load. That doesn’t automatically mean the bag should safely carry 25 kg of contents.
• Check what “waterproof” really means: Many bags are made from coated Oxford fabric, which makes them water-resistant. According to the product description, this protects against light rain and dust, but it’s no substitute for packaging that is waterproof over a prolonged period.
• Match the wheel size to where you’ll use it: Small standard wheels are suitable for smooth pavements and supermarket floors. For kerbs, gravel, cobbles or stairs, a shopping trolley with large wheels or a model with a stair-climbing mechanism is more practical.

The key things to consider when choosing a shopping trolley

1. Load capacity and frame construction

A stated load capacity of 20 to 25 kg is often enough for everyday shopping. If you’ll be carrying crates of drinks, parcels or heavy groceries, check the construction carefully. A steel frame offers different levels of stability from a very lightweight frame. For a folding sack truck or transport trolley, it’s also important to check whether the stated capacity applies to the unfolded platform or to a bag attached to the frame.

Before you buy, check:

• the maximum load for the frame and the bag;
• the frame tube material and diameter;
• the axles, joints and connecting parts;
• how evenly the weight is distributed when pulling the trolley.

Do not exceed the permitted load. Place heavy items as low down and as close to the axle as possible. This reduces the risk of tipping, but it doesn’t guarantee safe use on every surface.

2. Wheels for pavements, kerbs and stairs

A shopping trolley with two EVA wheels can move quietly on flat surfaces. EVA foam wheels are not the same as air-filled tyres: they don’t need a pump, but the level of comfort varies depending on their diameter and the surface.

A shopping trolley with a stair-climbing mechanism may be a good option for stairs. Models with six wheels, arranged in two three-wheel rotating systems, can tackle steps one at a time. Always move the trolley slowly and carefully. Product details are no substitute for the instruction manual; when carrying a load on stairs, secure it and don’t push the trolley over the steps if the manufacturer advises against doing so.

3. Bag, capacity and folded dimensions

Don’t choose a shopping trolley with a bag based on its litre capacity alone. Also look out for:

• Bag capacity: 25 to 30 litres is suitable for smaller shops; 38 to 45 litres gives you more room for a weekly shop.
• Material: 600D Oxford polyester is a commonly used, durable fabric.
• Closure: A cover protects the contents from dust and light rain.
• Extra pockets: A zipped pocket can hold keys, a phone or a purse.
• Folded dimensions: A shopping trolley that folds flat is easier to store behind a door, under a bed or in the boot.

A genuine 2-in-1 model can also be used as a transport aid without the bag. This means a 2-in-1 shopping trolley can also carry parcels, crates or laundry.

How to use and care for your shopping trolley

Before using it for the first time, check that the bag, frame and wheels are securely attached. If you have a folding shopping trolley, test the folding mechanism too. Keep your fingers clear of the joints and regularly check the screws, axles and wheel bearings.

To help your trolley last longer:

• dry the bag thoroughly after it gets wet;
• remove sand, hair and dirt from the wheels;
• distribute heavy loads evenly;
• store the trolley somewhere dry and out of prolonged direct sunlight;
• stay within the manufacturer’s maximum load capacity.

Frequently asked questions about shopping trolleys

How much weight should a shopping trolley be able to carry?

Models with a stated load capacity of 20 to 25 kg are often enough for everyday shopping. If you’ll be carrying crates of drinks or heavy parcels, check the load limits for the frame, bag and wheels separately. The lowest relevant limit is the one that matters.

Are shopping trolleys with six wheels suitable for every staircase?

No. A stair-climbing system can make it easier to move the trolley over certain steps, but it doesn’t remove the need to handle it carefully. Take the shape of the stairs, step height, load and instructions into account. When carrying a heavy load, pull the trolley carefully with both hands.

How long does a shopping trolley last?

Its lifespan depends on the load, surface, exposure to moisture, how often it’s folded and how well it’s maintained. A sturdy frame alone doesn’t guarantee a particular lifespan. Staying within the load limit, keeping the wheels clean and storing the trolley somewhere dry can help reduce common causes of wear.
