E4 modular system | With crossbars every link,
with crossbars every 2 link, more special solutions
nd
Almost endless combination options
The igus ® E4 modular system off ers almost unlimited combination options. For example, many
special solutions can be implemented, such as swarf protection using lids and bottoms (e-tubes) E4: four-piece energy
or the guidance of large vacuum hoses by using an extender crossbar. In the fi eld of standard chains. The largest
applications, the question is usually whether it has to be an e-chain ® with crossbars every link or product family in the
whether a more cost-eff ective version with crossbars every 2 nd link is suffi cient. There are technical igus ® product range. E4
requirements that make the use of an e-chain ® with crossbars every link necessary in order to e-chains ® : E4/4, E4.1,
achieve an optimum service life of the overall system. Generally speaking, in very demanding E4.1L and E4Q
applications and environmental conditions, the e-chain ® with crossbars every link off ers more
safety and stability, e.g. port cranes, steel mills, waste bunkers and composting plants.

When to use a version with crossbars every link?
● When guiding very thin cables to prevent the cables from moving out of place
● For narrow e-chains ® , to improve lateral stability
● For high lateral accelerations (> 5m/s²), e.g. for highly dynamic linear robots
● In high humidity, because the holding force of the crossbars is lower, e.g. in train washing E4 e-chains ® with
facilities, composting plants crossbars every link
● When guiding hydraulic hoses, in order to distribute the force of the hoses over more crossbars
● For travel lengths over 100m
● For gliding e-chains ® with travel speeds above 2m/s

When to use a version with crossbars every 2 link?
nd
If a version with crossbars every link is not required and the following advantages are to be gained:
● Interior separation easily attainable/accessible
● Less installation work (less crossbars) E4 e-chains ® with
● Approx. 10-15% more cost-eff ective depending on width crossbars every 2 nd link
● Up to 20% lighter depending on the width

E4 system special solutions: e-tubes, e-chains with extender crossbars and lids
®
e-tubes are used where cables need to be protected from
the impact of swarf and other small parts, e.g. in the working
area of machine tools.

The e-chains ® with extender crossbars are exceptionally
suitable for guiding very large vacuum hoses that have large
diameters and are relatively low weight. A large E4 extender
crossbar product range enables many application-specifi c
solutions
The use of additional extension links increases the fi lling
capacity and the maximum fi ll weight of the E4 e-chains®
while maintaining the same maximum unsupported length.
