HD-F738 Chair universal test machine

Chair universal test machine

Main function:

The machine is designed to test office chair arm( vertical and horizonal test ) and back strength. It with PLC controller, touch screen interface to input test parameters, test force and times can be set, count the time when reach setting force and return back automatically when time over.

Design standard: BIFMA  X5.1-2011  5、6、10、13、14、15、16、19、20

Backrest Strength Test - Static - Type l Applicability 

This backrest strength test shall be performed on Type I chairs.  For chairs with tilt locks, locking the chair changes the chair type (See Section 4) and must also be tested according to Section 6 in the upright locked position.  An additional chair may be used for the Section 6 testing.   Note: This test does not apply to chairs with backrest height less than 200 mm (7.9 in.). 

Arm Strength Test - Vertical – Static Applicability

This test applies to all chairs with arms. The purpose of the test is to evaluate the ability of a chair and arm to withstand stresses caused by applying vertical forces on the arm(s).

Main technical parameters:

Main Parameters:

1、 Tension mechanism, servo motor and the strap pulley architecture, the intensity of the rotation transformed into tension and supplemented force values ​​turn sensor read correctly tension, the action of the closed-loop control of servo motor to achieve a number of pull. Static and cyclic testing. Rally and speed can be set free. Mainly used for 5, 6,13,14,15, and 16 test.

2、In addition to this machine is also configured with two groups of electric actuator, respectively, for a group of the vertical apparatus and the horizontal apparatus 1 group, each group independently adjust the speed and thrust. Stroke is 500mm

3、 The vertical means of the servo motor can be used for the actuator, the vertical position adjustment, mainly used for the first 11.4,22,23 and 24 of the test; the maximum pressure is 150 kg.

4、 Level device servo motor caused the brake position adjustment of the pieces up and down and left and right mobile and flexible to meet the demand for different test location, is mainly used for 10,12.3 and 12.4 testing. 50 kg maximum thrust, adjustable up and down the range from 500 mm to 1200 mm。

5、 the bottom plate of the test machine drilling multiple rows of screw holes for easy installation of different attachments and fixed test conditions

6、 each electric actuator front-end with a quick connector for easy replacement of the load block and fixture

7、 control mode: PLC with LCD touch screen

8、 the maximum tension value：150kg

9、 the maximum thrust value（horizontal）：50kg

10、the maximum pressure value（Vertical）150kg

11、Can be equipped with computers, recording force and displacement changes.

12、  Capacity: 0-500kg

13、Setting time: 0-99S

14、 Machine size: （L×W×H）1500×1400×1800mm

15、Test accessories:  One test platform for arm test; arm vertical test grips; one back strength test grips.
