What is the purpose of an elevator's load weigh scale?

The purpose of an elevator's load weigh scale primarily revolves around its function to monitor and ensure that the elevator does not exceed its rated load capacity. This is crucial for several reasons: it helps maintain passenger safety by preventing overloading, which can lead to equipment failure or accidents. Additionally, adhering to the rated load capacity ensures the efficient functioning of the elevator system, as elevators are designed to operate optimally within specified weight limits.

The load weigh scale continuously monitors the weight of the elevator car’s contents and can provide feedback to the control system. If the weight exceeds the predetermined limit, the system can trigger warning signals or prevent the elevator from moving, thereby protecting both the passengers and the elevator equipment. This feature is integral to elevator safety protocols and is a critical element of elevator design and maintenance.
