LT-JJ05 Office chair pull back repeated testing machine

The product description

This machine is suitable for testing the life of the chair tilting mechanism and the durability of the chair back. This equipment is multi-functional test equipment. The cylinder can rotate with the beam and move along the beam. The beam height can be adjusted electrically. Cylinder can choose the output force or according to the specified position to do repeated linear motion. The loading pad is separated from the back of the chair, and the back of the chair is naturally restored to its original state by its own elastic force after unloading. Precise manual pressure regulating valve ensures stable and reliable cylinder output force, and digital display cylinder output force value. RPM speed is displayed and can be adjusted continuously.
