LIFT

 MEKASTAR 

---

Electric lifts, commonly known as elevators, are electrically powered devices designed for vertical transportation of people and goods in multi-story buildings. They operate using a traction system where a motor drives cables over pulleys, balancing the lift car with a counterweight to save energy. 

**Benefits include:**

**Safety:** Reduces accidents associated with stairs, especially for vulnerable individuals.

- **Efficiency:** Consumes less energy and offers predictive maintenance.

**Comfort:** Provides smooth travel with minimal vibrations.

**Versatility:** Suitable for various applications, from residential to commercial settings.

What are the main safety features of electrical lifts

Electric lifts incorporate several critical safety features to ensure passenger safety and prevent accidents:

**Overload Sensors:** Prevent operation if weight exceeds capacity, displaying a warning message.

**Overspeed Governor:** Engages brakes if the lift exceeds safe speed, preventing free fall.

**Door Lock Safety Switches:** Ensure the elevator cannot move if doors are not fully closed, avoiding accidents during entry and exit.

**Anti-Trap System:** Detects obstructions and prevents doors from closing on passengers.

**Buffers:** Absorb shock in case of a free fall, protecting passengers and equipment. 

These features work together to maintain a high level of safety in electric lifts.
