LT-JJ06 Office chair rotary life testing machine

The product description

This machine is suitable for all kinds of chairs with rotating seat cushion. The motor drives the test platform to rotate, and the frequency converter controls the motor's rotating speed and speed conversion. Precise pressure regulation ensures stable and reliable cylinder output force. Cylinder output ends with universal joint, and adapts to different Angle of the chair surface. Simple clamping structure, automatic centering, no vertical stress on the chair foot, simulating the real state. The cylinder output force height is adjustable to suit different chair heights.
