Ninghe Office Chair Comprehensive Tester

No device directly named 'Ninghe Office Chair Comprehensive Tester' was found, but there are several similar office chair comprehensive testing devices available for reference.

1. Office Chair Armrest Comprehensive Tester: This device focuses on testing the armrests of office chairs and features core three-directional testing capabilities, covering left-right swing, up-down movement (lifting durability), and forward-backward movement (push-pull durability) tests. It adopts a three-in-one integrated design, allowing a single device to simultaneously cover these three sets of actions, effectively saving laboratory space and procurement costs. The left and right armrests can be tested synchronously or independently. In terms of standard compliance, it meets the armrest durability testing clauses of the American standard BIFMA X5.1, the Chinese national standard QB/T 2280, and the European standard EN 1728, satisfying the needs of office chair factory quality inspections and third-party laboratory certifications. Its loading method is high-precision pneumatic loading, and the universal adjustable fixtures can accommodate armrests of different sizes.
2. Office Desk and Chair Comprehensive Tester: This device is equipped with five pneumatic brakes, including one vertical unit and four horizontal units. Each unit can independently adjust speed and thrust, with a stroke of 500mm. The brakes of the vertical unit can be adjusted in forward-backward and up-down positions, while the four brakes of the horizontal unit can be adjusted in up-down amplitude positions and moved left and right. The tester's base plate is drilled with multiple rows of screw holes, facilitating the installation of different accessories and the fixation of testing conditions. Each pneumatic brake is equipped with a quick connector at the front end for easy replacement of different loading blocks and fixtures. Its controller uses a PLC and a color touch screen, with a maximum pulling force of 200kg, a maximum pushing force (horizontal) of 60kg, and a maximum pressing force (vertical) of 130kg.
3. LT - JJ10 - A Office Chair Comprehensive Mechanical Tester: It integrates multiple mechanical testing functions, enabling a single device to complete a full range of tests on office chairs, including static strength, dynamic fatigue, stability, and impact. Core testing items include seat surface static pressure and repeated impact tests, backrest pull-back fatigue tests, armrest strength and durability tests, lateral stability and swing tests, and special tests for footrests and reclining mechanisms. This device offers core advantages such as multi-functionality, cost reduction and efficiency enhancement, modular independent control, precise measurement and reliable data, strong versatility and wide adaptability, and multiple safety protections.
4. Office Chair Impact Comprehensive Tester: Its impact speed can be adjusted within the range of 5 to 40 cycles per minute or as specified. The power supply is 1∮, AC220V, 50Hz, 5A, and it weighs 290kg. It can be customized. The control method is a touch screen + PLC. The machine dimensions are 25009001700mm, with a maximum output stroke of 600mm, a test platform width of 1000mm, a cylinder output force greater than 150 kgf, and a vertical pressing plate diameter of ￠127±13 mm.
