Maintenance precautions for explosion-proof electric hoists: 1. Maintain explosion-proof performance: This is the goal of maintenance for explosion-proof hoists. Any operation that damages the explosion-proof structure (especially the flameproof surface, fasteners, introduction devices) may cause it to lose its explosion-proof capability, which is extremely dangerous when used in hazardous locations! It is strictly forbidden to modify or repair the explosion-proof structure by oneself. 2. Use original or certified spare parts: When replacing key components such as chains, hooks, sprockets, brake pads, fasteners, seals, etc., it is necessary to use original equipment parts provided by the manufacturer or certified spare parts that fully comply with the original equipment's explosion-proof level and specifications. Arbitrary replacement may destroy the explosion-proof performance. 3. Prohibit the use of non-explosion-proof lubricants: Ordinary greases may contain volatile solvents, metal powders, or generate static electricity, which can become ignition sources in hazardous environments. It is essential to use the explosion-proof type of lubricant specified in the equipment manual.
