WKJC-100 computerized scaffold member testing machine

Inquiry
  Post Date: Dec 09,2016
  Expiry Date: Dec 09,2017
  Detailed Description: 1. Test standard
GB/T16491-2008 electronic universal testing machine
JJG139-2014 verification regulation of tension, compression and universal testing machines
GB/T24911-2010 bowl-coupler type steel tube scaffolding members
GB/T 15831-2006 steel tube scaffold couplers

2. Applications
It is mainly used to test mechanical performance of scaffold couplers made of malleable cast iron or cast steel with diameter various from 48.3mm to 51mm.
Max. Tensile force, tensile strength, deformation and elongation of Couplers or fastenings, used in the industries like municipal administration, water conservancy, chemical industry, metallurgy, coal and watercraft, etc, can be examined and tested by the testing machine as well.
Strength of bell shape cap, bowl shape socket, flat tube cross joint, weld strength of flat tube cross joint and compression strength of jack support etc.

3. Features
1) Adopting aluminum alloy cover, with attractive streamline structure
2) lead screws bear tension force only to prolong life-span and stiff stability
3) Adopting original ball screw loading mode. Interval is eliminated by double nut to make sure high rigidity of frame.
4) Adopting AC servo motor and driver, low noise precise planetary reducer, small volume, high efficiency, low noise, high accelerated speed, high reliable and less adjustment link.
5) Speed can be adjusted freely from 0.01mm/min to 500mm/min quickly and easily.
6) Closed loop control of constant displacement, constant force and constant strain, high antijamming capability and stability.

4. Brief introductions of relative test requirements
Slip resistance test right angle coupler When load value is 7KN,displacement of flat tube cross should less than 7mm;

when load value is 10KN,displacement of coupler cover plate on standing tube should be less than 0.5mm
swivel coupler hen load value is 7KN,displacement of flat tube cross should less than 7mm;

when load value is 10KN,displacement of coupler cover plate on standing tube should be less than 0.5mm
damage resistance test right angle coupler When load is 25KN, each part of coupler should not be damaged
swivel coupler When load is 17KN, each part of coupler should not be damaged
torsional rigidity test right angle coupler When torsional moment is 900Nm, displacement should be less than 70mm
tension test sleeve coupler When load is 4KN, displacement should be less than 2mm
compression test base-plate coupler When load is 50KN, each part of coupler should not be damaged

tension test of bell shape cap 1.Loading from 0KN to 15KN and then release completely
2.after release completely, loading from 0KN to 30KN and keep at 30KN for 2min, each part of coupler should not be damaged
strength of bowl shape socket 1.loading from 0KN to 30KN and then release completely
2.after release completely, loading from 0KN to 60KN and keep at 60KN for 2min, each part of coupler should not be damaged
strength of flat tube cross joint 1.loading from 0KN to 25KN and then release completely
2.after release completely, loading from 0KN to 50KN and keep at 50KN for 2min, each part of coupler should not be damaged
weld strength of flat tube cross joint 1.loading from 0KN to 10KN and then release completely
2.after release completely, loading from 0KN to 25KN and keep at 25KN for 2min, each part of coupler should not be damaged
compress test of jack support 1.loading from 0KN to 50KN and then release completely
2.after release completely, loading from 0KN to 100KN and keep at 100KN for 2min, each part of coupler should not be damaged
