The profile (1)
Li

ht, compact and self-supportin
g
aluminium
profile construction. Available in the followin
g
cross-sections:
80x80 mm (HLE80)
100x100 mm (HLE100)
150x150 mm (HLE150)
All profiles feature a total of ei
g
ht lon
g
itudinal
clamping grooves for the attachment of addi-
tional mechanical components and for the
connection of several HLE units. These
grooves also serve as attachment and mount-
ing points for initiators and mechanical swit-
ches.
To
g
ether with the HAUSER cover profiles (8),
these can be used as cable ducts.
The carriage (2)
Li

ht, ri
g
id carria
g
es with plastic rollers
mounted on roller bearin
g
s and eccentric axles
for pla
y
-free carria
g
e settin
g
s on all sides.
Overall, this results in high mechanical effi-
cienc
y
and virtuall
y
wear-free operation. The
carria
g
e can be supplied in two len
g
ths, either
standard or extended.
We can also produce special carria
g
es for
customised applications.
The tensioning station (3)
An easily maintained and assembly-friendly
tensioning station for setting the tension re-
quired for the timing belt and its orientation
(parallelism of pulleys).
The drive station (4)
Robust cast casin
g
with standard flan
g
e. Man
y
g
earboxes can be directl
y
flan
g
e-mounted (for
bore pattern, refer to dimensions).
On request, this can be supplied with the drive
shaft on the right, on the left or on both sides.
The timing belt (5)
The timin
g
belt has no pla
y
and is reinforced
by integral steel wires, thereby ensuring maxi-
mum travel speeds and repeatability.
Clamping of timing belt (6)
The timin
g
belt clampin
g
an
g
le
g
uarantees a
secure connection between the timin
g
belt and
the carriage.
The clampin
g
s
y
stem allows the timin
g
belt to
be replaced without the load attachment plate
having to be dismantled. This means that at-
tachments do not normally need to be re-
moved.
The load attachment plate (7)
The longitudinal grooves integrated on
the top of the plate offer many options for
the assembly of attachments.
When used in conjunction with the
clampin
g
profile (pa
g
e 26) this allows for
simple incorporation in a multi-axis sys-
tem.
Simple and adjustable attachment of oper-
atin
g
cams or switch lu
g
s b
y
means of
lon
g
itudinal
g
rooves on the sides and on
the underside of the plate.
Hei
g
ht and bolt points are unaffected when
the steel strip cover is attached at a later
date.
Special designs are also available on request.
The optional drive motor (9)
Parker servo motor with resolver and an ap-
propriate planetar
y
g
earbox form an optimum
drive for dynamic and accurate applications.
When used together with the COMPAX com-
pact servo controller, the HLE becomes a
complete, read

-to-run automation s
y
stem for
sin
g
le and multi-axis travel and continuous
path controls.
The V2A version (option V)
Minimum particle emissions and hi
g
h levels of
resistance to water and various cleanin
g
a
g
ents make the V2A version the number one
choice for use in clean rooms or the food in-
dustry.
The steel components are made of V2A mate-
rial and the rollers and pulle

mountin
g
s are
fitted with corrosion-resistant bearings.
