Get the name of a game object with position ?

I’m creating a Sokoban game and I want that my player push the crate.

I found how to detect if there is a game object in front of the cube, but I don’t know how to get the name/tag of the cube, so I can’t push the crate.

Actual code :

    checkPosition = transform.position + Vector3(0f,32f,0f);
    		hitColliders = Physics.OverlapSphere(checkPosition, 1);
    		if(hitColliders.length < 1) 
    			transform.position.y += 32f;

Sorry for the faults, English is not my mother language.

The script at:

shows how to iterate over the objects that the test has found. Inside the while loop just Debug.Log the name of the collider.
