Re: Breaking gears in PG77
We were looking at a similar problem with our pickup arm for Aerial Assist. One of our interim solutions used a belt reduction rather than gears. When the arm was struck, the belt jumped teeth rather than shattering anything.
However, we switched to pneumatics a few days later for concerns of consistency; this was long before bag-and-tag.
Another route might be not to use spur gears, but a lead screw/jack screw for the final reduction.
