Double Main Girders Warehouse Overhead Crane Reliable Structure With Long Life Span

Customized European Double Girder Overhead Crane Bridge Crane

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.

Product advantages:

1. Double main girders, box-type shaped by wielding;

2. High quality carbon steel Q235B and Q345B;

3. Double girder connected by high strength screws;

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.

Mechanical parts

Steel plate material Q235 or Q345B ( similar with foreign steel plate Fe3 or Fe52).

Main wels joint adopts union melt welding, nondestructive inspection.

After welding, main girder is through shot blasting treatment, gets Sa2.5 class, and eliminate welding stress.

Main girder and end girder adopts bolted connection to ensure strength and accuracy of the whole set.

The trolley and crane adopt three-trinity driving mechanism, frequency stepless speed regulating, hard-tooth surface, disc brake.

Crane driving IP55, F class insulation, contact continuity reaches 40% ED.

Epoxy zin-rich paint, a long service life, beautiful outlook and lustre.

Crane buffer block, anti-derail end plate

Electrical parts

Safe slide wire provides power whose conductivity is high and voltage drop is small, and current collector slide speed is swift.

Lifting mechanism, trolley and crane can be controlled independently, and work synchronously or individually.

Reasonable layout, simple maintenance and insulation class IP55 for electric control box

Flat cable, galvanized track and cable pulley for trolley traveling power supply, smooth traveling

Electric contactless module speed regulation controlling

Smooth traveling, lifting, and pushing-on

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.

To guarantee the normal operation of crane and avoid the personal casualty and mechanical damage, the safety device we provide are not only the electric protective devices or alarm bell but also other equipments as following:

1.Overload Limit Switch

2. Rubber Buffers 3.Electric Protective Devices

4.Emergency Stop System

5.Voltage Lower Protection Function

6. Current Overload Protection System

7. Rail Anchoring
8.Lifting Height Limit Device

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.

Attention:

Safety is the most important issue for cranes. To ensure the safety,It is prohibited to use the equipment in the combustible, explosive or corrosives environment.(Need explosion proof type for this).the following safety devices are equiped in Crane.

1.Crane traveling limit switch.

2.Weight overload protection device.

3.Lifting height limit device.

4.Voltage lower protection function.

5.Emergency stop function.

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.

FAQ

1. What certificates can your factory provide?

We have CE and ISO certificates. If you need special certificates such as special CO(certificate of origin), please let me know in advance. We need to verify the manufacturing cost of the certificates.

2. What kind of documents will be delivered together with the crane?

In general,there will be instruction manual,product certificate,technical specifications table,factory inspection report,and crane general drawing,etc.

3. How to ensure that the purchased crane can reach my factory safely and put into production smoothly?

1) The most important thing for a company's long-term development is its reputation.

2) We have perfect production process control system, storage system, packaging system, QC system and pre shipment inspection system;

3) After the crane arrive at the site, we will send an engineer to guide the installation. After the installation, we will train the operators until they can operate the crane normally;
