The internal structure of a running wire rope electric hoist typically consists of several key components that work together to lift and move loads safely and efficiently. While specific designs may vary depending on the manufacturer and model, the following are common components found in most electric hoists:

1. Electric Motor: The electric motor is the primary power source of the hoist. It converts electrical energy into mechanical energy to drive the lifting mechanism. Electric motors in hoists are often either AC (alternating current) or DC (direct current) motors, depending on the application and design.

2. Gearbox: The gearbox is responsible for transmitting power from the electric motor to the hoist's drum or gear train. It contains a series of gears that provide torque multiplication and speed reduction to optimize the hoist's lifting capabilities.

3. Drum or Sheaves: The drum or sheaves are components around which the wire rope is wound or routed. In a wire rope electric hoist, the drum is typically used to wind and unwind the wire rope during lifting and lowering operations. Sheaves may be used for redirecting the wire rope's path, especially in hoists with multiple reeving arrangements.

4. Wire Rope: The wire rope is a critical lifting element of the hoist, providing the means to lift and lower loads. It consists of multiple strands of steel wire wound together to form a strong and flexible cable. The wire rope is wound around the drum or routed through sheaves to support and move the load.

5. Brake System: The brake system is essential for controlling the movement of the load and preventing it from slipping or falling when the hoist is not in operation. Electric hoists typically use either mechanical brakes, electromagnetic brakes, or regenerative braking systems to hold the load securely when the motor is not engaged.

6. Control System: The control system comprises switches, relays, and other electrical components that regulate the hoist's operation. It includes controls for lifting, lowering, and traversing (if applicable), as well as safety features such as limit switches, overload protection, and emergency stop buttons.

7. Frame and Housing: The frame and housing provide structural support and protection for the internal components of the hoist. They are typically made of durable materials such as steel or aluminum and designed to withstand the rigors of lifting heavy loads in industrial environments.

8. Limit Switches: Limit switches are safety devices that prevent the hoist from overtraveling or reaching the end of its lifting range. They are installed at predetermined points along the hoist's travel path and automatically stop the hoist when activated, helping to prevent accidents and damage to the equipment.

9. Hook or Lifting Attachment: The hook or lifting attachment is the point of connection between the hoist and the load being lifted. It is typically equipped with a latch or safety catch to secure the load during lifting and prevent accidental disengagement.

10. Optional Features: Depending on the hoist's design and application requirements, additional features such as variable speed control, remote operation capabilities, and load monitoring systems may be included to enhance performance, safety, and convenience.

Overall, the internal structure of a running wire rope electric hoist is designed to provide reliable and efficient lifting capabilities while prioritizing safety, durability, and ease of operation in various industrial settings. Regular maintenance and inspection of these components are essential to ensure the hoist operates safely and effectively over its service life.
