In the Retail world, the shopping trolley is a constant companion. Although its appearance may seem unchanged since Watson's horizontally stackable cart prototypes in 1946, a thorough exploration reveals a significant evolution over the years.
In this article, let's explore the details of this silent transformation.
Wheels Rolling Toward the Future:
Today, we find double ball-bearing wheels that don't lock, as the rotational movement relies on a series of internal balls rather than an axle. The wheels have a quality coating (rubber, gum...) that provides smooth and silent movement.
This is essential for today's trolleys to glide effortlessly through aisles, offering a seamless shopping experience.
Relevant detail: In Europe, most trolleys have four swivel wheels, while on the other side of the Atlantic, the preference is often for two fixed rear wheels and two swivel wheels at the front.
Ingenious Options: Coin Slots, Scan Holders, and More:
The introduction of options such as integrated coin slots, mobile or fixed scan holders, and ergo-stick handles has added a practical dimension to our shopping experience.
These clever additions have simplified the purchasing process, transforming the trolley from a simple carrier into a multifunctional tool.
The Quest for the Perfect Materials: Metal vs. Plastic:
One of the ongoing debates in the trolley universe is the choice of materials. Metal, sturdy and durable, has long been the favorite. However, plastic carts are gaining popularity due to their lightweight, customization options, and resistance.
The dilemma between the robustness of metal and the versatility of plastic is at the heart of this evolution. Many retailers opt for hybrid trolleys, combining a metal base with a custom plastic basket, tinted in the color of their choice..
Highly Resilient Metal Coating:
The raw steel used to manufacture the trolley is now coated with quality options to ensure a long lifespan:
Galvanization : Applying a layer of zinc to protect the steel from corrosion. This process is often applied through electroplating, where the trolley is immersed in an electrolyte bath containing zinc ions.
Epoxy : A durable and shock-resistant option, available in different colors, offering protection against corrosion.
Stainless Steel : Although expensive, stainless steel carts are extremely resistant to corrosion and offer excellent durability. They are often used in specific environments, such as upscale supermarkets.
Eco-Friendly Plastics:
Recycled polypropylene (PPR) is now used in trolley manufacturing. It boasts high strength, durability, and versatility. When recycled, polypropylene can be used to create new products, contributing to reducing dependence on virgin plastics and minimizing environmental impact.
Derived from the collection and sorting of waste, which can include various plastic packaging, containers, and products found both on land and in the seas. These wastes are then cleaned, crushed, and transformed into small particles called granules. These granules are used as raw material for the manufacturing of new products..
Towards the Future: The Race Continues:
While we admire the past evolution, what about the future? Will self-service trolleys continue to reinvent themselves? The integration of smart technologies, increased sustainability, and even more ergonomic designs could be the next chapters in this ever-evolving story.
The self-service cart, often taken for granted, actually hides a fascinating history of discreet innovation. As a faithful companion to our shopping trips, it remains to be seen how it will continue to adapt to the changing needs of consumers.
Stay tuned for the next developments in the dynamic world of shopping carts!
