Task
Flexible cables and cords must be able to withstand the flexing and bending movement which occurs in normal usage. The stress in practical use is simulated by means of the test with e.g. 60 000 load cycles.
During the test the sample is bent after each other into two opposite directions over a prescribed bending radius. For this purpose the cable to be checked is led over two pulleys on a carrier which moves to and fro.
Test Machine
The PTL Flexibility Test Machines are suitable for the stress by means of pulleys up to diameter 200 mm. The carrier is equipped with recirculating-ball bearing bushes which run on hardened and ground guideways. In accordance with the standards it is driven by means of a circulating chain. A connecting rod with ball-bearings is used for coupling the carrier with the driving chain. These features ensure that the carrier guide has almost no slackness, is easy to maintain and relatively quiet.
Attaching and removing the sample
s
The PTL Flexibility Test Machines have been designed so that the time required for attaching and removing the cables under test is kept as small as possible. It is not necessary - even in the case of the multiple test machines - to thread the cables.
For this reason the table has side slots. All clamps to fasten and to load the samples are designed in such a manner that, without changing parts, 16 different openings are provided to suit the different cable shapes and dimensions. Tightening is carried out by knurled nuts. It is possible to exchange the pulleys quickly.
