This is the chain ball lifter ,with high and low limit switches .

How does it work?

It is design for loading under speed like a fork lift , the arms have just the proper rake on
them to lift the ball as you drive forward. As you drive forward all you do is pop the arm up and you are ready to fire the hammer ,the hammer swings around and KaBOOM shoots the ball . You can also catch if you drive around with the
arm up and in the right place for a catch . Limit switches are used to provide
protection for the motor. It is a very simple ,but effective. :slight_smile:
