Bus Seat Tester-QINSUN

1. Function and Application

The Bus Seat Tester is designed to evaluate the durability, strength, and fatigue performance of bus seating systems in compliance with FMVSS 222 and NHTSA S5.1.3 / S5.1.4 standards.

It can be mounted directly to the customer’s existing bedplate or supplied with a dedicated base. All mechanical functions are fully electric, eliminating hydraulic systems, for precise, repeatable testing.

The system is ideal for manufacturers, quality control, and safety compliance laboratories, providing both static and dynamic load testing in tension and compression to simulate real-world usage and safety conditions.
