Explosion-Proof Single Girder Overhead Crane LB

INTRODUCTION

Why this LB type 3-20 ton single girder overhead crane is an explosion-proof crane? Because the motors, electrical appliances, hoist trolley, rope guide, driving wheels, and hoists are all processed with spark-free.


The structure of this crane is the same as that of the LD-type single girder overhead crane. Both cranes are constituted by main beam, end carriage, electric hoist with a trolley, and electrical control system, but LB type is explosion-proof.


The explosion-proof marks are ExdIIBT4 (explosion-proof class III), ExdIICT4 (explosion-proof grade 4). According to regulations, the motor and electrics of this crane are explosion-proof type, and when the explosion-proof level is ExIICT4, the operating mechanism shall be treated with spark prevention.
