Lat Down Machine

Hey everybody,
my colleague Michele because of a pain all around his left elbow is not able at the moment to perform any pulling/pushing exercise.
A trainer in our gym told him to use a lat down machine as an alternative to vertical and horizontal pulling exercises. Here is a description of this machine:
you perform this movement seated, at the beginning bent arms up overhead. Below the elbows are positioned two rollers. With the side of both arms you push down these rollers along your body.
I’d like to know your opinion and if there are other better alternatives.
