A wheeled conveyance, such as a shopping cart, a luggage cart, a utility cart, a wheel chair, a gurney, or a tricycle has a metal chassis and wheels, which support the metal chassis above a supporting surface, such as a floor surface, and which may isolate the metal chassis electrically from the supporting surface. The metal chassis is grounded to the supporting surface by an elongate, flexible member, which is made from a non-metallic, static-dissipative material, such as a polyvinyl chloride, and which is arranged to drag along the supporting surface when the wheeled conveyance is moved along the supporting surface. Each wheel has an axle, on which such wheel is rotatable, and the elongate member can be mechanically and electrically connected to the axle of one of the wheels.
