YBJ2 series winch with explosion-proof motor is driven scheduling winch coal mine or on the ground, in the middle of the roadway tub and traction winch heavy machinery and equipment for special motors. This series motors with high efficiency, appearance, safe and reliable operation, long life, excellent performance, easy installation and other maintenance features.

YBJ Explosion-proof performance motor execution GB3836.1-2000 "Electrical apparatus for explosive gas atmospheres - Part 1: General requirements" and GB3836.2-2000 "Electrical apparatus for explosive gas atmospheres - Part 2: flameproof" d "requirement, also attached together IEC79-1, BS4683 and EN50018 regulations made flameproof. Ex logo ExdⅠ, for a coal mine with a combustible gas (methane) with air to form an explosive gas atmosphere or the presence of explosive coal dust hazardous locations. As the lifting and pulling heavy machinery driving force purposes. YJ common type is suitable for environments where explosive gas mixtures
