A tray used to support maintenance tools and service materials along an open bay in the side of a vehicle. The tray prevents these items from being damaged, or becoming foreign objects or debris that enter the open bay. The tray includes hanger assemblies that releasably attach the tray to bay door latches. Adjustable length standoffs connect the tray to the side of the vehicle to support and prevent swaying of the tray.

Portable tray and installation method

An air curtain arrangement and method of operating the arrangement are provided. The arrangement includes at least one air curtain unit having a supply plenum, a return air duct, and an intermediate air duct therebetween and separates relatively warm and cold areas. The air curtain discharges an air stream across a doorway from an outlet aperture of a discharge plenum toward an air return duct, at a discharge angle. A portion of the air stream is received at an inlet aperture of the return air duct. The portion of the air stream that is received at the air return duct is monitored. The discharge angle is adjusted to maximize the portion of the air that is received. One embodiment controls the discharge angle based on the temperature of the received portion of the air stream. Another embodiment senses the force of the air stream received proximate the inlet aperture.
