Household carts on wheels - as it was. ..
For all of its history, mankind has made not so many epoch-making, ingenious inventions, and one of them literally turned the world-the wheel. Elementary wheel, which turns rotary motion into translational motion. With the sharply increased speed of movement, the carrying capacity of vehicles has increased at times. Yes, and the very concept of a vehicle, in fact, appeared only with the invention of the wheel.
All kinds of utility carts allow you to move large loads with the application of relatively small forces precisely due to this ingenious invention. To date, there are many kinds of household carts. And the question itself, which model to call economic, causes a lot of controversy.
With housewives the housewives go shopping, while their husbands are already transporting bricks and land to other dachas. They are also used for moving goods in warehouses, ramps, factories and farms-in short, in all branches of the economy.
But the main external difference is in the number of wheels they are equipped with. There are trolleys one-, two-, three- and four-wheeled, but today we are more interested in household trolleys, which are compact in size with relatively high carrying capacity. That is, such options that find daily application in our life.
Household trolleys - what kinds of products can be found on the market?
All modern household carts on wheels with a soft drive of the raised passableness are assembled, thanks to what the silent movement with the minimal application of efforts is achieved. Most of them are two-wheeled, as the most convenient to operate.
Such carts take up a minimum of storage and transportation space, unlike single-wheelers do not roll over and do not heel sideways when driving, are simple and obedient to use.
The industry produces and bag-trolleys, which are a conventional folding shopping cart with a cloth bag attached to its frame. Such assistants are especially convenient when visiting shops and on country trips, since with a large volume of internal space they are equipped with a large number of all kinds of pockets and valves.
Also for this type of trolley is characterized by convenient external fasteners, which allow additional placement of the load directly on the surface of the bag. If necessary, a bag of dense material is quickly removed from the frame, after which the cart can be used to transport oversized cargo weighing up to 60 kg.
An economic cart - what should you remember when designing yourself?
Speaking of shopping bags, shopping carts, you can not fail to mention such a form of them as a folding trolley economic reinforced. This is a platform-type truck on 4 wheels, capable of carrying a cargo of up to 100 kg on stony roads. To increase maneuverability, it is equipped with a rotatable wheel support. When folded, it takes up little space in one plane.
To all household carts, the requirements are quite stringent:
- Compact. Compliance with this requirement is ensured by a folding structure;
- Strength. The presence of a lot of folding and detachable parts should not affect the strength and durability of the assembled structure;
- Light weight. The ability to carry significant weights at its own small mass is the most important characteristic of the trolley;
- Affordable price. As a rule, people who do not have sufficient means to purchase a car resort to the help of this auxiliary tool.
In conclusion, I would like to note that there are a lot of drawings and schemes for self-made household carts, but all of them must meet the above requirements.
