Single Beam European Style Travelling Bridge Crane Remote Control

Top quality remote control European single beam bridge traveling crane

Product Description of European Type Single Beam Overhead Crane

European single girder overhead crane based on bringing in and assimilating foreign advanced technology, this type of crane takes modular design theories as guidance, uses modern computer technology as means, introduces optimized and reliable design methods, Which is a new type of crane made by employing import configuration, new material and technology and has features in light-weight, generalizing energy-conservation and environmental protection, maintenance-free and high technology content design, production, and inspection carry out the last issued relevant national standard, equivalently adopts some foreign criteria including FEM, DIN and IEC.

Main Features of European single girder overhead 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.

Descriptions of Main girder:

1. Main beam uses bias-rail box-type structure, with optimized design and light self-weight.

2. Steel plate material Q235-B.

3. The cover and web of main beam should get surface rust removal by roller-way conveyor blasting machine before welding, this blasting machine can perform blanking, sandblasting, painting and drying, and after that they get to Sa2 level.

4. Prepared deflection upwards for feeding of main beam web complies with principles of quadric parabolic, use CAD to compute the corresponding high point and CNC plasma cutting machine to conduct cutting and blanking.

5. The welding of main beam should be performed on working platform. In order to avoid distortion of main beam, our company adopts U-shaped main beam assembly machine with hydraulic forming which has won national patent ensuring that vertical deflection degree between joint edge of stiffened and web plate and upper cover should not more than H/200, and also efficiently reduce the partial wave of web plate.

Electric meahanism:European Electric Hoist

The hoisting mechanism employs double-winding squirrel-cage pole-changing motor to achieve speed ratio of 1:6 shell of motor is made of aluminum alloy by extruding, which has good dissipation. The fan is installed to the end of motor in order to enhance cooling effects, thermal resistor is embedded into winding group of motor to prevent probable motor overheating.

The motor has F insulation level and protection level IP54

As to the variable-frequency motor of hoisting mechanism, encoder is allowed to install, which is ordinarily installed to fan shaft end of motor.

Technique features:

• It has low current for start and large torque;
• With soft starting and good performance in speed up;
• Have long service life;
• The technique parameter comply with standards of FEM and HMI;

With high rotational speed and low noise;

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.
