If I'm reading this correctly, this is one of the few cases where it is easy to get pneumatic cylinders to stop halfway.

Just dump all of the air on the other side - if the tote is between the arms of the cylinders, and unless the cylinders can exert enough force to deform or brake the totes, the arms will stop shortly after meeting the ends of the tote, and hold it with a steady pressure. The grabber is "self-adjusting".
