How is the working height of an elevating platform measured?

The working height of an elevating platform is measured from the ground to the highest platform rail. This measurement is significant because it indicates the maximum reach of the platform, ensuring that users know how high they can safely work while on the platform. It is crucial for ensuring safety regulations are met, as it directly relates to the platform's capacity to elevate to certain heights for various tasks. This standard allows operators to compare the performance of different elevating platforms and ensure that they select the appropriate device for their specific application, leading to safer work practices and compliance with safety requirements.

The other measurement methods do not accurately represent the reach and capabilities of the platform in relation to worker safety and potential hazards since they either measure from an incorrect reference point or do not account for the maximum height accessible for completing tasks.
