Does the charcoal tray on the BarbeSkew II raise and lower?

No. Because of the size limitations of the BarbeSkew II, the charcoal tray simply sits on the base of the body. However since everything rotates, the food does not burn. However the charcoal tray does lift out meaning it can be cleaned easily – we recommend that you line the charcoal tray with silver foil prior to lighting the charcoal as this makes it simple to clean the next day.
