igus E2 hydraulic chain securely guiding hydraulic hoses in small spaces

Treotham has introduced a new energy chain designed to
reduce maintenance intervals of construction machinery and mobile cranes.

The new igus E2 hydraulic chain functions as an energy and media guide even for the smallest installation spaces on
support legs. Strong, space-saving and easy to install, the igus e-chain guides
two hydraulic hoses in addition to power and control cables. The E2 hydraulic
chain is an ideal solution for special mechanical engineering, and its use
significantly reduces the costs of maintenance and downtime.

Special challenges require innovative solutions. This
is particularly true for support legs on many construction machines, such as
concrete pumps or mobile cranes, which are characterised by a large variety of
models. The safe guidance of hydraulic hoses is of crucial importance here,
because they need to provide the machines constantly and reliably even under
high mechanical stress and strong weather conditions. The igus E2 hydraulic
chain from Treotham not only protects the internal cables, but also prevents
torsion and bending of the hoses through the predefined minimum bend radius.

Proven
technology even for heavy construction machinery

For a long time, igus has been using the principle of
the ‘extender crossbars’ when it comes to creating more interior space for the
guidance of hoses. For the E2/000 series and the E4.1 and E4.1L systems,
extender crossbars, in addition to normal crossbars, can be used with high
holding power to accommodate additional hoses with larger diameters. Thus the
entire energy and media guidance can be provided by one system.

For the new E2 hydraulic chain, the concept was
applied to the installation space-specific conditions of support legs on
concrete pumps and mobile cranes. A one-piece, very solid extender crossbar
design and the heavy-duty pin/bore connection ensure high strength, even for
large unsupported lengths. The extender crossbars are injection moulded
directly on the side link, offering optimal hose guidance and stability. It is
also possible to place two hoses safely one above the other.

Since energy and hydraulics can be guided within a
single hydraulic chain, the requirement for installation space is greatly
reduced. The hydraulic chain has an external width of just 41.2mm and an
external height of 57.5mm. The predefined minimum bend radius is 75mm. The
total required installation height for the chain is only 255mm. Thus, the E2
hydraulic chain can be integrated into almost any application, such as close to
the base or on the side wall of support legs, a concrete pump or a mobile
crane.

Gentle
hose guidance for less maintenance

Since hydraulic hoses, which are usually operated at
extremely high pressure, have to endure a lot in dynamic applications, they are
very maintenance-intensive. The E2 hydraulic chain meets this challenge in two
ways: The extender crossbars and e-chain are made of tribologically optimised
plastic, reducing the abrasion and protecting the hoses. In addition to this
material advantage of tribo-polymers, its special design also reduces wear to a
minimum. Both the extender crossbars and the interior of the chain are designed
to protect the hose. Rounded contours and wide and smooth contact surfaces keep
abrasion and wear of the hydraulic hoses low. The segmentation of the cable
types also reduces the strain on the cables.

Electrical and hydraulic guidances are completely
separated by chambers. This follows the principle that cables and hoses with
very different diameters should always be run separately. This is important
because power or control cables have a maximum thickness of 5mm, while the
hydraulic hoses can be up to 20mm. Normally, a clearance space of 20% must be
allowed for, since hydraulic hoses expand transversely and lengthwise when
pressurised. Designed to the last detail, the E2 hydraulic chain can offer
freedom from maintenance.
