Explosion-Proof Single Girder Overhead Crane LB
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.
1). Light structure, easy installation, and maintenance;
2). Widely used in different places such as factories, warehouses, and material yards;
3). Reasonable structure, big lifting capacity;
4). Low noise, soft starting, and stopping;
5). Safe and reliable operation;
6). Low-cost maintenance, long service life;
7). Strong box type girder, welded by welding robot;
8). Wheels, wire rope, drum, gears, couplings are processed by CNC machine center, TOP quality control;
9). Heavy-duty slip ring motor, Or squirrel cage motor with VVVF, IP54 or IP44, insulation class F or H, soft starting and smooth running;
10). Siemens's main electric parts are used for durable and safe operation.
