Learn Russian: Они никогда не возят оборудование на носилках. - They never transport equipment on stretchers.

Возят is the multidirectional verb (from возить). Because the sentence uses никогда (never), it is talking about a general rule or repeated lack of action rather than a single specific trip happening right now. For general habits or recurring events, we always use the multidirectional verb.

I thought возить meant transporting by vehicle. Are stretchers considered a vehicle?

In Russian, you use возить (multidirectional) or везти (unidirectional) whenever the object is being supported by wheels, an animal, or some kind of carrying device, even if a person is powering it. So moving things on a cart, in a wheelchair, or on a stretcher (на носилках) all use these vehicle verbs instead of the carrying-by-hand verbs (носить or нести).

Why does the sentence use both никогда and не?

Russian requires a double negative. When you use a negative word like никогда (never), you must also put не (not) right before the verb. It literally translates to 'They never do not transport'.

What case is оборудование in?

It is in the accusative case because it is the direct object (the thing being transported). Since оборудование is an inanimate neuter noun, its accusative form looks exactly the same as its dictionary form.
