Product Description
Product Overview

The HK-811 Office Chair Backrest Cycling Durability Testing Machine is designed to evaluate the fatigue resistance and wear performance of office chair backrests when subjected to repeated backward forces. It is widely used by R&D teams, quality inspection departments, and certification labs to ensure furniture complies with international standards.
Functions & Applications
* Simulates repeated pulling forces on the backrest to test fatigue and durability.
* PLC control with touchscreen interface for easy operation.
* Adjustable pull force from 0–200 kg to meet different testing requirements.
* Automatic stop when preset cycle count is reached, with power-off memory function.
* Applicable for office chair backrest evaluation in compliance with BIFMA standards.
