The AW–DZ type explosion-proof vehicle stopper consists of an explosion-proof controller and a gate; it is primarily used in conjunction with a quantitative loading control system. It automatically controls the release of vehicles based on various interlock conditions, while also providing standard dry-contact signals to the loading device and other automatic control systems, thereby enabling effective interlock control for safe loading. The equipment meets the requirements of relevant safety standards and is particularly suitable for handling flammable, explosive, and other liquid petrochemical products. Product features: (1) The control input/output sections use optocoupled relays respectively ； (2) There is no issue of gear wear without a belt, and no oiling is required ； (3) The gate is controlled by an explosion-proof controller, which receives commands from third-party devices to enable automatic lifting and lowering of the gate ； (4) High adaptability, with no vibration in the lift rod. Technical parameters: (1) Input voltage: 220VAC; (2) Explosion protection rating: ExdⅡBT4 Gb; (3) Dimensions of the equipment enclosure: 400*270*1050; (4) Effective rod length: 2–6 meters; (5) Rod lowering speed: 3/6 seconds, selectable; (6) Equipment power: 120W; (7) Input/output signals: dry contact input/output; (8) Operating temperature of the mechanism: -25 ℃ to +85 ℃; (9) Operating temperature of the electrical control box: -20 ℃ to +75 ℃; (10) Weight: 60KG ；
