Product description:
High quality LB type electric traveling overhead single girder crane with explosion proof performance
LB type 1-20 ton explosion-proof single-beam bridge crane: motors, electrical appliances, electric hoist sports cars, rope guides,driving wheels and hoists are all explosion-proof.The structure of the explosion-proof single-girder overhead crane is the same as that of the ordinary LDA electric single-girder overhead crane. Both are composed of a single main beam, end beam, and electric hoist, but it is explosion-proof.
The explosion-proof marks are ExdIIBT4 (three-level explosion-proof), ExdIICT4 (fourth-level explosion-proof).
LB type explosion-proof electric single beam crane According to regulations, the motor and electrical of this crane are explosion-proof type, and when the explosion-proof level is ExIICT4, the operating mechanism shall carry out spark-proof treatment.The whole machine complies with the regulations of B 7T10219 2001 "Explosion-proof Beam Crane", explosion-proof gradeThey are ExdIIBT4 and ExdIICT4. They have reasonable structure, beautiful appearance and strong explosion-proof.
The proof marks are Exd ll BT4 and Exd ll CT4. Explosion proof Single girder overhead bridge crane is applied to sites, where is not higher than the II B or II C-class, and the sites with explosive air mixture formed with inflammable gas (or steam) and air whose factory ignition temperature groups of not less than the T4 group. We designs and manufactures the material handling equipment for the harsh and hazardous application environments, such as chemical plants, gas power plants, paint shops, oil refineries, and waste water treatment plants, etc.
