foundry industry

We have specifically for foundry industry metallurgical crane, and has obtained the country allow manufacturing production license, and sent us to the domestic and international numerous casting enterprise excellent crane products, our products, we strictly follow the national standards and requirements:
1. Adopt special metallurgy lifting motor, when the environment temperature for more than 40 ℃, should choose class H insulation of the motor;
2. Installed two sets of independent action of the brake (double brake);
3. Must furnish the weight limiter;
4. Hold different forms of rotary and (generally as heavy hammer) the rise of the double stop limit position (double spacing), and should be controlled different cut-off device, lifting height is more than 20 m crane, should also be installed according to need down limit position limit;
5. Use silicon controlled the stator voltage regulator, eddy current brake, brake energy consumption, thyristor power supply, dc power supply control unit and other may cause because of the speed speeding and more than 20 t used for lifting hoist gm bridge crane molten metal must have the overspeed protection;
6. Lifting mechanism should have positive and negative to the co
