How does the garbage man pick up the smaller trash can?

So we have the normal two dump trash cans. One is for recycling and the other for waste. And then we have two additional ones for grass and natural wastes. How does the garbage man pick up these two cans?

The latter trash cans look more like this

So I’m wondering if the garbage man manually picks it up, or if the truck also carries it with some kind of lifter. My company is EDCO, in San Diego.
