A key safety feature in elevator design concerning load limits is the implementation of weight sensors in the car. These sensors play a crucial role in ensuring that the elevator operates within its designated load capacity. When passengers enter the elevator, these sensors continually measure the current load. If the weight exceeds the specified limit, the system is designed to prevent the elevator from operating, thereby avoiding potential mechanical overloads that could compromise safety.

In addition to protecting the elevator itself, weight sensors contribute to passenger safety by preventing accidents associated with overcrowding. This helps to maintain the reliability and longevity of the elevator's mechanical components, as running an elevator beyond its load limit can lead to excessive wear or catastrophic failure.

Other safety features, such as emergency communication devices, regular inspection protocols, and visual indicators of weight load, are important for overall safety and operational efficiency but do not address the specific mechanism of limiting the elevator's load during operation. Visual indicators may inform users of the current weight, but they do not actively monitor or prevent operation if a weight limit is exceeded. Similarly, emergency devices and inspection routines enhance safety but rely on proper functioning systems that include features like weight sensors.
