NLH European Standard Electric Hoist Double Girder Overhead Crane

Lifting Weight: 5-70 tons

Lifting Height: 6-12m or Design

Span: 10.5m-31.5m or Design

NLH double girder overhead crane is designed and manufactured with European standard. The lifting capacity of this crane can be up to 70 tons. The trolley is installed between two main girders. Thus it increases the traveling scope of spreader. This crane is with reliable performance, flexible application range, easy to operate and convenient to maintain.

Lightweight and Modular Design:

1. Overall height is 20%~25% lower than traditional cranes;

2. Self-weight is lighter by 20%~30%;

3. Max load reduces 15%~20%;

4. Smaller limiting size increases working scope;

5. Light structure reduces the cost of workshops;

6. Every component designed to be a standard series and interchangeable;

7. Modularization design is easy for transporting;

8. Standard modular design makes good quality and fast delivery.

Advanced Manufacturing Technology:

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:

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.
