trolleys

Trolleys are wheeled devices designed to move goods and items with minimal lifting. They include pushcarts, hand trucks, hospital service trolleys, and shopping trolleys, among others. They are used in retail, hospitality, healthcare, logistics, and transit settings. In some regions, the term trolley is preferred over cart for shopping devices, while in North America the term cart is common.

Shopping trolleys consist of a metal or plastic frame with a basket mounted above a base or cage, four wheels, and a handle. Front wheels may swivel for maneuverability; some models have fold-down seats or child seats. Many systems use a coin, token, or electronic mechanism to release a trolley and require a return deposit.

Other trolleys include hand trucks (dollies) used to move heavy items; hospital trolleys for transporting patients, meals, and medicines; hotel service trolleys for room service; luggage trolleys in airports and stations; and catering or banqueting trolleys. Trolleys are also used in manufacturing and distribution to move components and supplies between work areas.

Design and safety considerations vary by application. Materials range from steel and aluminum to high-density plastics; wheels may be solid rubber, polyurethane, or pneumatic. Weight capacity varies widely; professional trolleys often include brakes, anti-tip mechanisms, and ergonomic handles. Regular maintenance includes wheel inspection, lubrication, and cleaning to prevent corrosion and ensure smooth operation.

History and regional variations reflect the device’s broad utility. Early carts developed from simple pushcarts, with modern four-wheeled designs becoming standard in many industries during the 20th century. The word trolley is common in Britain and many Commonwealth countries, while cart is prevalent in the United States for shopping devices, and trolley may refer to trams or service carts in other contexts.
