For mechanical fatigue test of finished functional sofa, developed according to WSI standards. Pull-back function sofa, set the force value under the seat surface → pull-back open leg support pop out → pull-back working cylinder reset → backrest push out set force value → backrest reset → leg support work, reset leg support → seat surface unload, repeat this action 25000 times, fix the armrest fixture on the armrest. Set the setting force value when the seat surface is pressed down → the armrest cylinder places the weight on the fixture → the backrest is pushed out and the setting force value → the backrest is reset → the leg support work, reset the leg support → the seat surface is unloaded → the armrest weight is lifted and unloaded. Repeat this action 25000 times.

Seat surface standard loading module, 100kg

Backrest standard loading module, backrest applied 34-45kg (according to the finished product)

The leg support part is reset by pulling down the rope, the stroke is 1000mm (electric)

Pull button function sofa: pull button fatigue design a special fixture to fix the pull button, connect the cylinder through the pull rope, the cylinder can adjust the stroke to meet the test of different pull button sizes

No pull button functional sofa: two sets of armrest fixed frame, by lifting heavy objects to achieve loading (2-10kg), for no pull button functional sofa

Machine size: L1600×D1500×H2100mm

Weight: 350kg

Voltage: 220V, 1000W
