The profile (1)
Light, compact and self-supporting
aluminium profile construction.
Available in the following cross-
sections:
100x100 mm (HLEZ100)
150x150 mm (HLEZ150)
All profiles have a total of seven
grooves along their length for
clamping further mechanical com-
ponents and for joining several
HLEZ and HLE units. These
grooves also serve as attachment
and mounting points for sensors
and mechanical switches.
Together with the cover profiles
(2), these can be used as cable
ducts.
The carriage (3)
Lightweight, rigid carriage with
plastic wheels mounted on roller
bearings (4) and eccentric axles for
playfree carriage settings on all
sides.
Overall, this results in high mecha-
nical efficiency and virtually wear-
free operation. The carriage can be
supplied in two lengths either stan-
dard or extended.
We can also produce special car-
riages for customised applications.
The load attachment plate (5)
The longitudinal grooves integrated
on the top of the plate offer many
options for the assembly of attach-
ments. When used together with
the clamping profiles (refer to page
26) this allows simple incorporation
in a multi-axis system.
Simple and adjustable attachment
of operating cams or switch lugs is
provided by longitudinal grooves
on the sides and on the underside
of the plate.
Special designs are also available
on request.
The drive module (6)
Compact drive module, can option-
ally be supplied fitted on either
side of the load attachment plate.
For a description of the drive prin-
ciple, refer to page 18.
The optional Parker servo motor
(7) with resolver and an appropri-
ate planetary gearbox forms an
optimum drive for dynamic and
accurate applications.
When used together with the
COMPAX compact servo-control-
ler, the HLE becomes a complete,
ready-to-run automation system for
single and multi-axis travel and
continuous path controls.
