BIFMA Furniture Testing Equipment Office Chair Seat Forward Stability Tester
Application
The Chair Stability Tester is used to perform the forwards overbalancing test.
Principle
Put the test-piece on the test table, blocked the front leg, apply specified force with forward 20N applied at seat loading point, check the article tends to oventurn forward or not to determine the test-piece forward stability performance.
Install the loading basket under the table which is lifting by Pneumatic actuator, max loading capacity up to 150kg, the lift of cylinder is controlled by pneumatic attenuation device, Load-bearing basket adopt rubber cushioning device to ensure that fall to final position will not produce damage, the operation unit of table can control loading basket to rise or go down, dynamical movement can position device adjustment, easy to operation.
