MR Electric motor lifting hoist’s Advantage
MR 电动起重葫芦的优势 1. Electric motor partial outer cover: They are made of high strength aluminum system through compression casting formation. 1、电动机局部外盖： 采用高强度铝体系，经压铸成型而成。
Features: Solid and light, Fast release heat, Continuous use, Enclosed structure. Can be used in the chemical plants, electroplating factories, and other places.
特点：坚固轻便，快速释放热量，连续使用，封闭结构。可用于化工厂、电镀厂等场所。 2. Side kind braking: This masterly structure ensure the hoist absolutely safty when the power off. And ensures it is safe when has excess load. Also it combine to the motor braking as the double brake system to strengthen security and durability. 2.侧向制动： 这种精湛的结构确保了起重机在断电时绝对安全。并确保在有超负荷时是安全的。此外，它还与电机制动相结合，作为双制动系统，以增强安全性和耐用性。 3. Gear: The gear made of alloy steel and through the heat treatment 3.齿轮： 由合金钢制成并经过热处理的齿轮 4. Antiphase protector: When power-supply wiring mistake, the control circuit is unable to move. 4、反相保护器 ： 当电源接线错误时，控制电路无法移动。 5. Hooks: They are made by hot forging and heat treatment. 5、挂钩： 经热锻和热处理制成。 6. Chain: It is made of FEC80 ultra strong heat treatment alloy steel. 6、链条： 采用 FEC80 超强热处理合金钢制成。
Advantages: It is safely approximately when used in the rain water, the sea water, under the chemical and other bad conditions.
优点：在雨水、海水、化学品等恶劣条件下使用时，大约是安全的。 7. ISO: M5 /FEM: 2AM Insulation grade: F 7. ISO：M5 /FEM：2AM 绝缘等级：F 8. Protection class (hoist and push button): IP55 8.防护等级（提升机和按钮）：IP55 9. Powder supply: 3 phase, 200-600v, 50HZ 9.粉末供应： 三相，200-600v，50HZ 10. Noise (single/ double speed): 81dB. 10. 噪音（单速/双速）：81dB。
