Crown is harder in that you can cause serious injury/death much more easily. In my years at Target, we had a couple "near misses"..... whole pallets coming down from the top of the steel and almost landed on someone.
Personal grievance here: It's called a Stacker. Crown is the manufacturer, they make both the Stacker and the Wave equipment.
I've been with Target for over two years now, and I just learned how to use a pallet jack a few weeks ago. Then again, when would a cashier use a pallet jack?
Just take your time, look around 360 & you will be ready to go. Practice with crown & wave, when not busy. Learn to look for safe pallets up in steel, thank those tm's for being safe. Take down & fix any unstable pallets, that you deem unsafe. More practice for you & faster to pull the product for guests or during pulls.The sketchiest thing about the Wave in terms of difficulty is getting the hang of turning while going in reverse. But that doesn't take long to master.
With the other one, it just boggles my mind how overnight must be using it. I try to get pallets down that they put up, and I wonder how in the holy f*** they got it up there in the first place. It should be so simple to put stuff up in the steel, yet I somehow always find myself needing to straddle a green upright, run over the bolts in the ground on the green uprights, UNstack the pallet partially with the Wave first because it's going to hit pipes otherwise, stabilize the pallet while it's still on the steel because even one single millimeter of movement makes half of it fall over, etc. I wish I could watch them use it. It must be a sight to behold.
