An espresso cart is a rolling counter loaded with heavy, water-filled equipment. Stabilize the machine and grinder, drain the water, and lock the wheels so nothing rolls or slides mid-move.
Pro tip: Photograph the machine's plumbing and electrical hookups so the cart is service-ready the moment it lands.
Watch out: Never move an espresso machine with a hot or pressurized boiler; drain and cool it first to avoid burns and internal damage.
