Here’s a comparative table that categorizes different parts of an Electric Overhead Traveling (EOT) crane based on their function and importance in the overall operation of the crane:
| Component Category | Components | Function |
|---|---|---|
| Structural Elements | Main girder(s), End trucks, Bridge, Cross girders | Provide structural support and enable movement along the runway. |
| Lifting Mechanism | Hoist, Drum, Wire rope, Hook block | Facilitate the lifting and lowering of loads. |
| Movement System | Trolley frame, Wheels, Bridge motor, Trolley motor | Allow horizontal movement of the load along the bridge and vertical movement across the workshop. |
| Control System | Pendant control, Remote control, Operator’s cabin, Control panels | Enable operators to control the crane’s movements and operations safely and efficiently. |
| Safety Devices | Overload protection, Emergency stop system, Rail clamps, Anti-collision devices | Ensure the crane operates within safe parameters to prevent accidents. |
| Power Transmission | Motors, Gearboxes, Reduction gears, Couplings | Transmit power from the motor to the crane components, facilitating their movements. |
| Braking System | Hoist brake, Trolley brake, Bridge brake | Control the stopping and holding of the crane and its components to ensure safe operation. |
| Electrical Equipment | Electrical panel, Limit switches, Festoon system, Conductor bars | Distribute and regulate electrical power to various crane components and control movements. |
| Auxiliary Equipment | Cable reels, Light fixtures, Warning alarms | Provide additional functionality and safety measures such as lighting and signaling during crane operation. |
This table organizes EOT crane parts into functional categories, illustrating their roles in ensuring the efficient and safe operation of the crane. Each component is vital for specific tasks, contributing to the overall functionality and reliability of the crane system.
