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 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).
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.
