Технические параметры

a.base size -1.5m(W)×2m(L)×2m(H)

b.Vertical post- Quantity:2 units Height:1.5m

c.Cross bar-Quantity:1 unit Height:adjustable(powered)

d.Horizontal force application (strength test)

-1 unit pulley sistem(pneumatic) to pull& push (specifice force) the arm rest of single or multiple seating chair

-Height adjustable- 500-1500mm.

-The minimun horizantal distance between pulley and arm rest -30mm(adjustable).

-Timer- 1 minute pull& 1 minute push.

e.Vertical force application(strength test)

-Can use the same pulley for horizontal force but the postion is under the arm rest to creat a vertical force.

-The minimum vertical distance armrest and pulley shall be 30 min(adjustable)

Timer- 1 minute vertical downward force.

f.Horizontal (outward)force (durability test)

-1.Pulley system using cable /strap to apply horizontal force for 50.000 cycles on the arm rest (heavy duty).

-The minimum horizontal distance between pulley and armrest -30mm(adjustable)

-Height adjustable- 500-1500mm.

-Control -6 digit

-Speed- 10-30 cycle/minute

g.Vertical (downward) force (durability test)

- 1 pulley system using cable/strap to apply

Vertical force for 10.000 cycle on the arm test (heavy duty)

The minnimum vertical distance between pulley and armrest -30mm(adjustable)

-Fixible positioning on the platform (under the arm rest)

-Counter -6 digit

-Speed - 10-30 cycle 1minute.

h.Pneumatic cylinder to operate the pulley system

Type of cylinder:Double-acting cylinder

Maximum force:2000 Newton

Air supply requirement:6 bar (Minimum)

i.Stopper - to restrain the chair base from sliding

j.Control Panel

-ON/OFF button

-LCD display- load meter,speed,cycle,time

-Load sensing setting -to ensure the furniture under test is not overloaded.

-Force selector - To select the predetermine force for testing

-Air regulator -Air regulator completed with pressure indicator shall be provided.

k.Safety feature

-Safety feature shall be installed to stop the operation of machine in case of emergency or when needs arise. This shall,result in retraction of pneumatic cylinder and unloading of the test sample. The safely feature shall also be able:

-To stop the test machine in the event of test sample failed.

-To protect test machine from mechanical damage in event of test sample failed, and the pneumatic cylinder will retract unloading the test sample.

-To stop the machine in the event of interrupted power supply.

-To stop the test machine at the end of a predetermined number of cycles/strokes.
