Advanced Manufacturing Technology of Overhead Crane with Electrical Diagram
1. Sandblast pretreatment on steel plates and the surface quality reaches Sa2.5;
2. CNC cutting machine cuts webs plate to insure the curved surface is smooth and accurate;
3. Seams are soldered by automatic arc welding and detected by ultrasonic and X-ray ;
4. The structure of girder and trolley is manufactured by floor-type boring lathe to insure flatness.
High Reliability of Overhead Crane with Electrical Diagram
1. Use imported motor with insulation grade of F and protection degree of IP54. With overheat alarm. The motor is shielded by aluminum alloy stretching cover with good heat dissipation performance;
2. Imported reducer from Germany. hardened gears with good bearing capacity, excellent seal without penetration of grease;
3. Main electric components imported from international brands such as: Siemens, Schneider and ABB etc. with protection degree not lower than IP54;
4. Wheels are forged by 65mn alloy steel with features of wear-proof, anti-fatigue and long service life.
5. Low energy consumption and maintenance free;
6. Whole crane energy saving about 30%;
7. All-in-one transmission mechanism making it work more efficient;
8. Variable frequency control whose high and low rotating speed ratio is 1:10 and work efficiency increases more than 20%;
9. Less and easy maintenance reduces the cost of maintenance;
10. Manufactured by advanced technology and constituted by high quality imported components greatly reducing malfunction and cost;
1. Trolley conductor or angle steel conductor power supply
2. Hoist and crane separately control, move separately or together
3. Flat cable or special cable power supply for electric hoist
4. Galvanize slide and cable trolley, smoothly moving, appearance is aesthetics
5. Electrical non-contact speed regulation control module
6. Operation, hoisting, the point start are very smoothly
7. Power leading has both methods of current collector and flexable cable
