Wheel diameter
The diameter of the wheel(s) of a wheelbarrow or trolley (see "Type"). Permeability primarily depends on this parameter: the larger the wheel, the less sensitive it is to pits and irregularities, and the easier it is to carry the entire structure over rough terrain. At the same time, in carts (including ladders, see "Type"), the diameter of the wheels is relatively small — it rarely exceeds 250 mm. But for wheelbarrows 200 – 250 mm is considered a very limited indicator — most models use wheels with a diameter of 300 to 400 mm.
Body capacity
The total volume of the body of a wheelbarrow or trolley (if any, see "Type"). The larger the body, the more cargo can be placed in it, especially when it comes to liquid or bulk materials. At the same time, it should be noted that manufacturers usually choose a body for a particular model taking into account its carrying capacity; therefore, when choosing, it makes sense to look first of all at the weight of the cargo being transported, and only then — at the volume of the body.
In addition, note that the volume is measured to the upper edge of the body — this means that loose or other materials that can be loaded “with a slide” can fit more in a wheelbarrow than stated in the volume specifications.
Body thickness
The thickness of the material from which the body is made.
Large thickness - more than 1 mm for metal bodies - has a positive effect on strength and reliability. On the other hand, it increases the dead weight of the product. In addition, do not forget that the overall quality of the wheelbarrow/trolley also depends on the specific body material (see below) and assembly features; and a durable body in itself does not mean high load-carrying capacity (see above).
Body material
The material from which the body of a wheelbarrow or trolley is made.
The most popular nowadays are
metal bodies — both painted and without paint; however, there are also
plastic products. Here are the main features of different materials:
— Unpainted metal. The most popular material nowadays. Most often, steel is used as a metal, supplemented with a protective zinc coating (see "Galvanized body"), less often — aluminium, which is lighter and does not require special coatings, but less durable and reliable. Anyway, there is no paint on such bodies. In general, unpainted metal is noticeably stronger than plastic, it is suitable for even the most capacious and lifting wheelbarrows / carts; at the same time, such material is much cheaper than the same metal, but painted. On the other hand, zinc coating is still not as resistant to adverse conditions as special paint, it requires careful observance of the operating rules and certain care (primarily cleaning and storage in a dry place); and aluminium bodies have their drawbacks mentioned above. In addition, all such cars have a characteristic metallic grey colour, there are no other shades among them (this moment does not affect performance, but may be important for some users).
— Painted metal. Metal (usually steel) coated with a special paint — usually powder. Like unpainted metal, it is reliable in itself and can be used even in the m
...ost "heavy" models. Specifically, the coating is not inferior to galvanizing in terms of mechanical strength, and surpasses it in terms of corrosion resistance: the paint is absolutely insensitive to moisture and most of the contaminants that a wheelbarrow / trolley has to deal with in fact. In addition, this type of coating can have almost any shade. Its main drawback is its rather high cost, which is why painted metal is much less common today than unpainted metal.
— Plastic. Plastic is noticeably inferior to metal in strength, so it is poorly suited for wheelbarrows and carts with a high load capacity. On the other hand, this material is noticeably lighter — so even a roomy plastic body will weigh less than a relatively small metal one. Therefore, many wheelbarrows and carts with a plastic body have a very significant capacity. And you should pay attention to this material first of all in cases where you need a device for transporting large quantities of relatively light, but voluminous cargo — such as fallen leaves or mowed grass. In addition, it is worth noting that plastic is completely insensitive to moisture.Galvanized body
This feature means that the wheelbarrow has a bare metal body (see "Body Material") with a protective zinc coating.
Galvanized nowadays is the majority of unpainted metal bodies. The presence of such a coating is practically guaranteed that the body is made of steel (for aluminium, inferior to steel in terms of performance, a special coating is not required). And the meaning of this feature is to protect against corrosion: a thin oxide film forms on the surface of zinc, which prevents the occurrence of rust. However galvanized metal is more demanding to care for and more sensitive to scratches than coated with a special paint (and scratches break the protective layer and lead to corrosion); on the other hand, paint is noticeably more expensive.
Support leg
The type of support posts provided for in the design of the wheelbarrow. Support legs are devices on which the wheelbarrow leans during parking (along with wheels).
— Non-
removable. Fixed support legs are usually part of the frame on which the body is mounted. They are stronger and more reliable than removable ones, but not as versatile.
—
Removable. Support legs that can be removed if necessary. This can be useful, for example, when driving over rough terrain, where the racks can touch various objects on the ground, or in cases where there is a separate support (bench, step, etc.) at the place where the wheelbarrow is installed. In addition, the removed racks somewhat reduce the overall weight of the wheelbarrow. Of their shortcomings, it is worth noting the lower reliability than non-removable ones (however, this becomes noticeable only during long-term operation at maximum loads).
Weight
Total weight of an empty wheelbarrow/cart in standard working configuration (if equipped with detachable support legs — with legs installed, see above). This parameter allows you to estimate how much excess weight you will have to carry with you in addition to the actual cargo. However it doesn't always make sense to chase light weight — it can mean less strength.
