Top Technique Single Beam European Style Electric Overhead 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.

Compared with the general QD bridge crane, its weight is reduced by about 15-30%. The maximum wheel pressure is reduced by about 10-35%, which can the requirements of crane for factory building structure and reduce production cost. As the core component of the driving mechanism, reducer gear pair with the hard tooth surface and high accuracy, together with steel reel forged wheel and variable-frequency speed regulating system, which makes this type of crane become renewal product of traditional general bridge crane and applied in the industry of machinery production, assembling petrochemicals, warehouse logistics, electric power construction, paper making and railways

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.

Safety systerm

Overload protection in the event of overload, the hoist unit switches off and only the lowering motion is possible

Long and cross travel limited by means of preliminary and final limit switches or Wireless anti-collision device

Anti-falling protection for the Three-in-One electric motor of trolley and crane prevents from accidental falling

All movements can be switched off by actuating the emergency-off switch at the control station via a main contact

High quality long time bearing polyurethane materials buffer fixed at the end of trolley travelling and crane travelling to prevent over traveling

Safety hook latch used for avoiding the lifted material out off from the hook

Audible and visual alarm device to inform the person stay near by the travelling crane.

Rain Cover for lifting mechanism of outdoor cranes, electric cabinet and driving mechanism

Protective earth conductor is fitted as standard

Voltage lower protection system

Current overload protection system

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.
