Light Structure European Overhead Crane High Reliability For Construction

Product Specification

European Style Hoist Novel End Trucks Design For Double Girder Overhead Crane Manufacture

Product Description

European type cranes have such design concepts as small dimension, light dead weight. Compared with traditional cranes, the limiting distance is minimum from hook to wall, and headroom is the lowest, which makes cranes work more close to the front, and lifting height more higher that increases effective working space of workplace.

New workshops can be designed more smaller and have more functions because the dead weight is light, and the wheel pressure is small. Smaller size workplace means saving a huge amount of money from initial construction investment, long-term heating, air conditioning and other maintenance free.

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.

4. Welding seams are tested by X-ray and ultrasound;

5. Forged wheels;

6. Compact structure, small volume and light weight trolley;

7. Lifting mechanism is open type winch trolley;

8. Compact reducer motor drive, step less control,hardened gears and safety disc brake;
9. Good operation performance, stepless speed regulating and running smoothly;

10. Main girders Shot blasting sa2.5 after welding to release internal stresses;
11. Painting high quality epoxy zinc-rich primer, and the thickness of oil film is 140μm.

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.

Operation

Several operation ways such as: ground flashlight door, remoter, flashlight door+remoter, etc.

Ground operation is simple, no need of professional operators, and operators have more freedom on the ground.

Double stop button or rocker type joystick

Customers can choose what they need.

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;

Main Features of European crane:

1.The small wheel pressure and small volume can reduce the investment in the preliminary works such as the factory building.

2.Using high-quality components can reduce failure rate and maintenance costs.

3.Low consumption of total power can reduce the costs, it had remakeable energy-saving effect.

4.Variable Frequency control make cranes run smoothly.

5.Standardize the whole crane coninguration to make the whole machine more stable.

6.Real-time security monitoring while crane running.

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.

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.

Packaging & Shipping

1. Electric parts are packed by high quality plywood crate, to reduce distortion in conveying.
2. Main beams, end beams and trolly/winch are packed by plastic woven cloth. It can reduce abrasion during the transportation.
3. If the size are suitable for container ship, usually by container.
4. Big size, usually by bulk ship or by container after truncation.
5. Transport ways are based on reducing cost & keep safety.
