冶金钢丝绳电动葫芦工作级别M5、M6；工作环境温度不高于60℃。，海拔高度在1000m以下，其使用场地不得有易燃易爆及腐蚀性气体，其适用电源为三相交流、50HZ、380V。
Metallurgical wire rope electric hoist, M6 level M5; working environment temperature is not higher than 60 ℃. , altitude below 1000m, the site has no flammable explosive and corrosive gas, suitable for three-phase AC power supply, 50HZ, 380V.
电动葫芦起升机构工作级别为M6，设有支持（工作）制动器和安全制动器。正常工作时由设在锥形转子电动机上的支持制动器对传动机构进行制动。如果从电动机至卷筒之间传动系统的任一环节发生故障，致使吊钩及载重物超速下降时，则由设在卷筒上的安全制动器将卷筒制动停止以防止载重物超速下降造成事故。
Electric hoist lifting work level mechanism for M6, a support (work) brake and safety brake. Normal working hours by a conical rotor motor on the brake on the transmission mechanism for braking. If from any link between the transmission system to the reel motor failure, the hook and weight was speeding down, by a safety brake drum drum brake to stop the will to prevent load speeding down the accident.
电动葫芦不仅设置了双制动而且设置有双起升限位和下降限位装置，同时设置了过流保护、失压保护、相序保护、起重量超载限制器、下降超速断电保护等多种安全保护装置。增强了电动葫芦的安全使用性能。电动机的绝缘等级为H级，采用钢芯6×371WR钢丝绳满足了冶金生产条件的需要。
Electric hoist only set up double braking is also provided with the double ceiling and drop limiting device, and set the overcurrent protection, under voltage protection, phase sequence protection, overload limiter, lifting weight down speeding power-off protection and other safety protection device. Enhancing the safety performance of the electric hoist. The insulation of the motor level is the H level, the steel core wire rope of 6 * 371WR meets the needs of metallurgical production conditions.
当减速器及电动机的下面设置了高温隔热保护功能，在电动葫芦卷筒外壳下方设计安装整机隔热板，以隔离熔融金属的高热辐射。
When the reducer and motor is provided with the high temperature heat insulation protection function, in the installation of the insulation board electric hoist reel casing is designed, high isolation of molten metal radiation.
