ZL-2003 Office Chair Rotation Durability Tester
1.Introduction:
Suitable for all types of chairs with swivel seat. The motor drives the test platform to rotate, and the frequency converter controls the rotation speed and speed conversion of the motor at multiple speeds; precise pressure regulation ensures stable and reliable output force of the cylinder; the output end of the cylinder is equipped with a universal joint to adapt to different angles of chair surfaces; simple clamping structure, automatic Alignment, no vertical force on the legs of the chair, simulating the real state; the height of the output force of the cylinder is adjustable to adapt to different chair heights.
