Office Chair Backrest & Armrest Strength Tester LT-JJ02-B

Short Description:

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.

Product Advantages

Combined Armrest and Backrest Testing – One bench covers both armrest strength and backrest strength, replacing two separate single-purpose rigs.
Standards-Correct Load Values – 50–300 lbf armrest loads and 890 N / 1334 N backrest loads match BIFMA X5.1, so results are comparable with certification laboratory data.
Ø127 mm Vertical Loading Pad – The standard armrest loading pad geometry distributes force exactly as the test method assumes, avoiding point-load distortion.
Functional and Destructive Backrest Loads – 890 N held 1 minute verifies function, and 1334 N held 1 minute verifies destruction resistance, on the same platform.
SMC Precision Pressure Control – Imported auto-adjust regulators hold cylinder force stable, with digital readout so the actual load is verified rather than assumed.
Real-Time PLC Monitoring – Speed, frequency, cycle count and force are displayed live on the touchscreen for a complete, auditable test record.
