TYSCI Technologies has designed and manufactured a machine for testing straps and webbing used in the lifting and transport industries.
The customer was specific in the requirement and the final design was a three metre test length with dual loading systems allowing straps to be tested from 2.5kN to 25kN and from 25kN to 250kN using 600mm stroke hydraulic cylinders.
Extension is measured using a potentiometer and, through the data acquisition system, % extension versus load is plotted.
Precision load cells were employed to measure the load and this is displayed on digital displays and, through using LaBVIEW, a test report is automatically generated.
Control of the load was kept simple using a manually controlled relief valve and pushbuttons.
Calibration of the machine was undertaken to Australian standard AS 2193 and certified to as a grade A machine on both load ranges.
As testing involves production testing it also involves destruction or proof testing. In the latter the operator is protected using sliding polycarbonate guards electrically interlocked with the loading system.
