123 Long travel "o ff the reel." Up to 100m travel pre- assembled and ready to install Automated storage/retrieval system with system E2 and chainflex ® cables - travel lengths up to80mand speedof v =4.5m/s Travel speeds and accelerations Travel speeds up to 5m/s in continuous operation are possible and in use on current applications. In special cases, up to 10m/s possible after consultation with igus ® . For example, E4 e-chains ® achieve speeds of 22m/s and accelerations of 784m/s 2 in crash test units. In these cases, however, only a few thousand cycles are required per year. Acceleration plays a crucial role in the life calculation. Di ff erentiations must be made between normal operational acceleration and a sudden jolt of acceleration such as unexpected stops or so-called "E-stops." Even in these situations, igus ® e-chains ® prove to be very durable. Service life We offer service life calculations for your application based on our extensive gliding Gliding | Long travels Corrosion-free igus ® guide troughs are available in the material: ● Galvanised steel ● AISI 316Ti/AISI 316L stainless steel material 1.4571/1.4404 upon request ● Seawater resistant aluminium application experience. As developers of polymer plain bearings, we possess vast material behaviour knowledge which we apply to the development of e-chains ® as well. Units with 200m travels have been in operation for 8 yearswithminimummaintenance. Units up to 60m travels have been in operation for 15 years with almost no maintenance. Please consult igus ® for references and calculations for your project. The maintenance-free aspects of igus ® e-chain systems ® over long periods and under harsh operating conditions is often the deciding factor in choosing igus ® . Our system guarantee (depends on the application) provides additional peace of mind. Technical environment Long travel applications using igus ® e-chains ® run in water, in dirt, in the tropics, in explosion risk areas (with special design features) and many other conditions. You will find more details in the Technical Environment section of this chapter. Guide troughs can be supplied in corrosion- free materials. Calculation Comprehensive tests place us in the position of knowing our products capabilities. Important factors in these tests are: ● Push/pull forces under both ambient and extreme temperatures ● Humidity and dirt ● Friction values of the polymers, alone and against various glide surfaces ● Behaviour of electrical cables under push/pull conditions ● Behaviour of hydraulic and media hoses under push/pull conditions ● Service life, and noise generation. If we cannot calculate your application based on these factors, we can carry out a test for you in our laboratory.
