An elevator system barbecue is a type of grill where the height of the cooking surface or the charcoal tray can be adjusted. In this system, the grill or charcoal tray can be moved up or down using a mechanism, often a handle or a crank. This allows for more precise control of the heat while grilling.

In simple terms, an elevator system barbecue enables you to adjust the distance between the food and the charcoal fire, making it easier to control the heat and ensuring the food cooks evenly and to the desired level. This system is especially useful for grilling meat, allowing for controlled cooking without burning while achieving the perfect doneness.
