Strength Durability Tester for chest desk and bed is used to simulate under the normal use or wrong use condition,to test the strength and durability of furniture suffered one-off or repetitive load.It is used for testing the mechanical performance of all kinds of desk chest and bed.

Testing :

This tester can be used for doing the horizontal static loading test and also can do horizontal durability test.Strength Durability Tester for chest desk and bed use four horizontal cylinders to loading cycling specificed force to the edges of specimen.

After a certain test number,check the structure of specimen,function etc. whether there is any damage.Then we could know the performance and defect of products.

Furture:

• The tester adopts the frame structure to design.The frame is made of high quality industrial aluminum, beautiful and generous.
• The adjustable part of the frame adopts pulley structure to design in order to adjust the loading position to adapt to different specifications of sample.
• The position handle is convenient to locate so that the tester can improve the work efficiency.
• The fixed block at the bottom can be adjusted freely different position to adapt to different specifications of sample.
• PLC controller to control the motion of the tester.It is simple to operate.
• Force value can be adjusted through the pressure changes in the precision pressure regulating valve.
• With high precision power sensor,sense the force value immediately.
• Every load group can be individual adjusted to control.Load force value is stable and reliable.The loading cushion is dismountable so that it is convenient to change different cushion to meet different test requirement.
