Normal for all forks.I have to say, I'm underwhelmed by my Artillian forks. They lock in place on the top, but not on the bottom--they can and do move on the track. I've tried to pick up items such as a balled tree, and as I drive the bottom of the forks start to spread and the tree drops. There should be a locking mechanism on the bottom too. If you're just lifting pallets, they will work fine.
