Original product description
The HY-644 is an office chair reclining durability tester intended for chairs equipped with a reclining seat base. It evaluates durability under repeated loading by securing the chair, applying a 225 lb load to the seat, and using an external force to move the chair between its front and rear stop positions.
The stated test procedure supports up to 3,000,000 reciprocating cycles at an adjustable cycle speed of 10–30 rpm, or at another specified speed. The machine has a 0–500 mm cylinder stroke and a cylinder pivot-height range of 70–150 cm with electric adjustment.
Test operation is managed through a PLC touch-screen controller. A Chinese-language micro-printer is included for test reports. The listed power requirement is single-phase AC 220 V, 0.5 A. Overall machine dimensions are 140 × 120 × 170 cm, and the listed equipment weight range is 100–500 kg.
The equipment is supplied in a wooden case. The product information identifies the test method as based on ANSI/BIFMA X5.1;buyers should confirm the exact standard edition, required test configuration, and whether the proposed machine setup covers their internal or third-party compliance program.
Before procurement, confirm the chair sizes and reclining mechanisms to be tested, fixture and clamping details, the required cycle count and speed, report language and data fields, electrical compatibility at the installation site, calibration documentation, accuracy interpretation, safety provisions, included accessories, commissioning requirements, and the final configured machine weight.
Customization availability and a one-year warranty are listed, but their scope and conditions should be documented in the purchase specification.
