The Operator’s Field of Vision (FOV) test, conducted in accordance with IS/ISO 5006:2017, is a vital assessment to ensure the safety and operational comfort of personnel operating Construction Equipment Vehicles (CEVs) / Earth-Moving Machinery. IS/ ISO 5006:2017 defines rigorous guidelines for evaluating the operator’s visibility from the driver's seat, with particular emphasis on the Filament Position Centre Point (FPCP), determined from the Seat Index Point (SIP) coordinates. The test includes assessment of masking areas, focusing on the Visibility Test Circle (a 24-meter diameter ground-level circle around the machine), and on the Rectangular Boundary on which a vertical test object is placed at a height specific to the machine type and its operating mass. These parameters are designed to simulate real-world operating conditions.
This paper introduces a portable testing setup developed specifically for conducting the Operator’s FOV test as per IS/ISO 5006:2017. The setup facilitates include accurate verification of X and Y coordinates of the SIP, Integration of a high-intensity light system to project and assess masking areas, and Quick & repeatable deployment in field conditions, enhancing usability across various types of CEVs and earth moving machinery. The portable design ensures adaptability, reduces overall testing time, and upholds the accuracy requirements stipulated by IS/ISO 5006:2017. This solution not only enables more efficient visibility assessments but also supports enhanced safety compliance for manufacturers and operators. It presents a cost-effective, field-deployable solution for ensuring visibility requirements in construction equipment vehicles / earth-moving equipment.
