Not sure about this equipment, but if a palletizer cannot last 4 years, that’s a big problem.
I’m in food and beverage, not cannabis, but we certainly do have effective off shifts. In many cases they can outperform 1st shift. We run 7 days a week most of the year.
If a machine goes down, our maintenance team is held to the fire until they can get it running - which they always deliver on. I’d be very nervous to rely on an outside stakeholder - who does not have their job on the line in the same way.
