Why do wheelbarrows that are used to lift heavy things have longer handles?

Because longer handles distribute weight more evenly, as apposed to shorter handles which are for lighter objects that don't require the same weight distribution.
add. And the length between the handles and the wheel axle may be considered as a lever, with the load carried in between.
[note. Chinese wheelbarrows of old used to have the wheel under the load, which makes for a more maneuverable wheelbarrow, but suited really to smooth country.]
