发明名称 VENTILATING SYSTEM FOR TRAVELLING CRANE CABS, EXHAUST HOODS AND THE LIKE
摘要 The ventilating, system is for travelling fume hoods and cabs of travelling vehicles such as cranes wherein an air supply or exhaust unit is located outside the area in which the hood or vehicle operates. The air supply or exhaust unit blows air to or exhausts gases through a duct having an elongated slot therein. In the case of the travelling vehicle an air scoop, receiving air from the slot and delivering it to the crane cab, travels back and forth in the slot as the crane travels and a special sealing device keeps the slot sealed in front of an behind the air scoop. The procedure is reversed when gases are being exhausted from a travelling fume hood or other travelling exhaust system.
