Office furniture comprehensive testing instrument
is simulated in everyday conditions, inspection rocking chair bearing durability. The test will be a certain shape, quality of load modules, placed on the seat in the rear seat back repeatedly push and pull action until after a certain number of test bearing conditions, this test can always conducive to improved product mix, eliminating potential quality problems, improve product durability and reliability.
2, the principle
Rocking chair with a seat surface shaped back position, the weight of the horizontal load of the module to load in the form of the predetermined frequency repetitive load movement.
3, the main technical parameters

Seat & the back testing: Load 950N on the seat, then load 330N on the back, action repeatedly 200000 times in the frequency less than 40 times/min.
Caster durability testing: Fix the office chair, load 400N on the caster repeatedly in the speed of 10~30 times/min, loading 60000 times in all.
The frame of this tester is used aluminium profile , pneumatic drive mode which is very clean and convenient.
