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 size
The size of the body is usually indicated by two numbers indicating the width and length along the upper edge — for example, 600x800 mm. With the same volume (see above), the larger the dimensions of the body, the smaller its depth; and knowing the volume and dimensions, you can approximately estimate the depth.
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.
