Both are composed of a single main beam, end beam, and electric hoist, but it is explosion-proof.
LB Explosion proof Single Girder Overhead Crane is improved and designed on the basis of LDA model. It is characterized by more reasonable structure, beautiful appearance and strong anti explosion characteristics, Used together with HB model, HBS model explosion-proof electric hoist as a complete set, mainly used in machinery manufacturing and places like assembling plants,storage houses.with the advantages of low energy consumption, strong rigidity, light weight, outstanding structural design, etc.
1). Light structure,easy installation and maintenance;
2). Widely used in different places for hoisting such as factories,warehouses and material yards;
3). Reasonable structure,strong bearing capacity ;
4). Low noise, soft starting and stopping ;
5). Safe and reliable operation ;
6). Low cost maintenance, long working life;
7). Strong box type,welding by machine hand;
8). Wheels,wirerope drum,gears, couplings are processed by CNC manchine center, TOP quality control;
9). Heavy duty slipring motor,or Sq.cage motor with VVVF, IP54 or IP44,insulation class F or H,soft starting and smooth running;
10). Siemens main electric parts are used for durable and safe operation;
