Office Chair Caster Equipment
The TST-F731 Rotating Chair Caster Dynamic Testing Machine is a professional instrument designed to evaluate the performance of office chair casters. Its core functions and design features are as follows:
1. Core Functions and Testing Standards
This device is primarily used to test the durability and wear of rotating office chairs during long-term use by simulating repeated rotational pressure to assess the reliability of the caster system. Its testing standards include internationally recognized BIFMA 5.1 (unidirectional/bidirectional rotation tests) and EN 1335 (forward/reverse rotation tests), ensuring that test results comply with industry norms. The equipment supports adjustable rotation angles (45ยฐ-355ยฐ) and can achieve continuous unidirectional 360ยฐ rotation. The rotating platform has a diameter of 800 mm, accommodating office chairs with a maximum seat width of 1000 mm, covering the size requirements of most office chairs.
2. Performance Parameters and Adjustment Range
The rotation speed can be adjusted between 5 and 20 cycles per minute, allowing users to customize settings based on testing needs. The device is equipped with a 113 kg weight and an electric lifting mechanism to accurately simulate various load conditions. The maximum number of test cycles is 999,999, meeting the demands of long-term durability testing. It operates on a single-phase AC 220V power supply, suitable for conventional laboratory or production environments.
3. Control System and Operational Convenience
The system combines a programmable logic controller (PLC) with an LCD display, supporting customization of test angles, directions, and dwell times to meet diverse testing requirements. For example, it can be set to perform reciprocating rotation within a specific angle range or simulate scenarios where users frequently start and stop. The high level of automation reduces manual intervention, enhancing testing efficiency and data accuracy.
4. Production and Application Scenarios
Manufactured by Dongguan Test Instrument Co., Ltd., with production in mainland China, this equipment is suitable for office chair manufacturers, quality inspection agencies, and R&D departments. It is used for performance verification during product development, quality control during production, or third-party certification testing. Its design balances functionality and safety, providing a scientific basis for evaluating the reliability of caster systems.
