Product Description

Product Description

Office Chair Backrest & Armrest Strength Tester

   The Office Chair Backrest and Armrest Strength Testing Machine is designed for comprehensive strength testing of office chair armrests and backrests. It simulates horizontal and vertical loads that may occur during normal use, heavy loading, and habitual misuse.

   The machine evaluates the load-bearing capacity and structural strength of chair armrests under static or repeated loading conditions, while the backrest test simulates the pressure applied when a user leans backward against the chair. It is suitable for functional-load and destructive-load testing, helping manufacturers and laboratories evaluate chair safety, durability, and structural reliability.

   The equipment adopts PLC control and a touchscreen interface for real-time monitoring of force, speed, frequency, and test cycles. A precision pressure-regulating system helps maintain stable cylinder output force for consistent testing results.

Specification

Product Advantages
1.Comprehensive Chair Testing – Combines armrest and backrest strength testing in one machine.
2.Stable Loading Force – SMC automatic or precision pressure regulation ensures reliable cylinder output.
3.Wide Load Range – Armrest loading force can be configured from 50 lb to 300 lb or as specified.
4.PLC Touchscreen Control – Displays force, speed, frequency, and test cycles in real time.
5.Adjustable Test Position – Loading position and cylinder stroke can be adjusted for different chair designs.
6.Functional and Destructive Tests – Supports both functional-load and destructive-load testing of chair backrests.
