3 Stations Chair Seating and Back Testing Machine GT-LB04-3B

Applications:

The chair seating and back tester tests the strength and durability of the seats and backrests by simulating the routine use loading of the seat.

The machine is equipped with 3 working position, which can test a three-seat chair or sofa at the same time.

Each working position equips with two drive units, and can be individually controlled to repeatedly load the test points of the seat. Through different parameter settings, the machine can complete the following types of test functions on the seat:

1. Seat and back static load test.

2. Seat and back durability test.

3. Seat front edge static load and durability tests;

4. Horizontal forward static loading test for backrest.

5. Headrest static load test,

6. Legs forward static load test,

7. Leg lateral direction static load test.

8. Arm and wing sideways static load test

9. Arm downwards static load test

10. Seat impact test

11. Back impact test

12. Arm impact test

Feature:

1.The machine adopts frame structure design. The frame is made of high quality industrial aluminum,  beautiful and easy to maintain.

2. Servo motor and air cylinder drive, the test loading control is more accurate, and the noise is even smaller.

3. PLC touch screen control makes the operation more convenient.

4. In addition, the machine loading device using electric control movements, more extensive test space.

FAQ:

Q1: As a premier furniture and chair testing equipment manufacturer, how does GESTER guarantee that this massive 3-station machine won't lose calibration during international shipping?
A1: Unlike local distributors who ship knocked-down parts, we engineer the GT-LB04-3B with an integrated rigid framework that undergoes structural stress relief before leaving our factory. The entire unit is anchored to a heavy-duty steel base, vacuum-sealed with anti-rust desiccant, and crated in IPPC-standard export plywood, ensuring your precision sensors and automated lifts arrive 100% calibrated and ready to run.

Q2: Running 3 stations and 6 pneumatic actuators simultaneously sounds like an energy drain. What are the actual infrastructure requirements?
A2: It requires standard 1-phase AC 220V (50/60Hz) power and a continuous compressed air supply of ≥0.6Mpa. To save your lab thousands in annual electricity costs, we combine high-precision servo proportional valves with low-friction cylinders. This smart, closed-loop system dynamically regulates air intake based on real-time force feedback, cutting air consumption by up to 35% compared to conventional multi-station pneumatic testers.

Q3: Can this machine test an entire 3-seater sofa and three completely different office chairs at the same time?

A3: Yes. The wide-span frame allows you to secure and test an entire 3-seater sofa or large lounge layout as a single component. Alternatively, because all 3 working positions feature fully independent PLC channels and isolated servo lines, you can test 3 independent chairs under completely different standards, forces, and cycle limits simultaneously to maximize your laboratory throughput.

Q4: Millions of cycles cause sensor drift in cheap machines. How does GESTER maintain long-term data accuracy for accredited labs?

A4: We build this machine utilizing premium, fatigue-rated load cells with cross-talk isolation. Backed by our high-speed closed-loop control system, the machine tests and self-corrects its output force millisecond-by-millisecond. Even during continuous 24/7 durability testing over hundreds of thousands of cycles, the force deviation is strictly held within a razor-thin ±1%, keeping your lab fully compliant with strict internal and external audits.
