European Standard Double Girder Bridge Crane

European Standard Double Girder Bridge Crane

Description

European type double girder bridge crane is a new type double girder bridge crane, compared with the normal double girder bridge crane, NLH adopts the FEM standard, structure is more compact, working more steady with low noise, the motor is ABB, reducer uses SEW, Siemens main electric parts, all these characteristics makes it more has more advantages compared with normal bridge crane.

The whole technical level reach to international and domestic advanced leading level. The crane's steel mechanism with professional design, structure optimization, meet the requirements of strength, rigidity and sability. During the design progress, we also take into account about the working environment, the design of steel structure considering the manufacture, inspection, transportation, installation and maintenance convenience. 

The electric hoist trolley adopt ND type steel wire rope electric hoist trolley, the standard traveling speed of crane is 3-30m/min, standard traveling speed of trolley is 2-20m/min. As for lifting speed, frequency control makes it has optional speed besides the standard speed to meet customers different requirement.

Light self-weight and compact structure can greatly reduce the cost of the warehouse, also spare more room for the lifting height, greatly take advantages of the warehouse.

Features

Lightweight and Modular Design:

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

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

3. Max wheel 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.

Specifications

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.

Safety:

1. Safety supervision system is with an overload limiter and shows the load value on screen to warn operator to avoid overload;

2. Before start up, the whole system will carry out self-checking includes: power supply voltage, default phase, validity of the safe protection device and the zero button;

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;

Intelligent:

1. Electric anti-sway tech realize accurate positioning;

2. Advanced electric control tech turn it into a crane robot with semi-automatic control and full-automatic control;
