General instructions:
When operated in areas with explosion hazard the instructions identified by the
symbol are to be observed. They have been prepared on the basis of the ignition dan-
ger rating KGA 130.
ATTENTION!
The observance of the operating and maintenance instructions is prerequisite for trouble-free
operation of the system and the acceptance of possible warranty claims.
Therefore read these instructions before starting work with the screw-jack gearbox! Pay spe-
cial attention to the safety instructions!
These operating and maintenance instructions are part of your product and contain important
information regarding maintenance and service; therefore they should always be kept close to
the screw-jack gearbox.

Important information
Directions and instructions for the operation in areas with explosion hazard
1. Short description
The ATLANTA high-performance (series 60) and standard (series 61) screw-jack gearboxes are used for
the conversion of rotary motions into linear motions. They are mostly driven by three-phase motors. Manual
operation is also possible. On consultation with ATLANTA other motors, e.g. servo motors, may be permis-
sible as special versions.
The gear units are available with rotating or non-rotating spindles. As standard version they are equipped
with trapezoidal-thread spindle and nut. Ball-screw drive is possible as special version.
The light-metal housing ensures optimal heat dissipation.
The gear units are delivered test-run, tested for tightness and consequently ready for operation. The spin-
dles are provided with an initial grease-lubrication sufficient for approx. 10 strokes.

2. Proper application
When operated in areas with explosion hazard the instructions identified by the symbol are
to be observed.
The ATLANTA screw-jack gearboxes may only be used for the conversion of rotary motions
into linear motions in mechanical engineering applications under atmospheric pressure condi-
tions.
The permissible input speed and output torque must not be exceeded. The layout instructions
according to the ATLANTA catalogue have to be observed.
The gear unit may be operated only in rooms with normal ambient pressure. The gear unit
must not be operated outdoors or at increased ambient pressure, and also not under water or
other liquids.
The gear unit may be operated only at ambient temperatures between +10 °C and +40 °C.
The gear unit is designed for intermittent operation. The duty cycles mentioned in the cata-
logue must not be exceeded.
Continuous operation (S1 acc. to DIN EN 60034-1) is not permissible without written approval
by ATLANTA.
The gear unit must not be used in combination with combustion engines – danger of overheat-
ing, inadmissible shock loading!
The gear unit is designed for power input via the worm shaft. The efficiency rating stated refers
to power input via the worm-shaft.
In combination with trapezoidal-thread spindles the gear unit is statically self-locking, but not
self
braking. The self-locking capacity can be weakened or neutralised by vibrations, unfavourable
lubricating conditions and smoothing of the surfaces after some time of operation.
In combination with ball-screw spindles the gear unit is neither self-locking nor self-braking.
The surface temperature of the gearbox must not exceed 80°C during operation.
When used in areas with explosion hazard, it may be necessary to measure the surface tem-
perature and to ensure warning or cut-off, if the temperature is exceeded.
Differing working conditions require written approval by ATLANTA.

3. Transport
Transport and handling may be carried out only by qualified or specially trained personnel.
Observe the safety regulations applying to transport and handling with lifting tackle.
The load must be handled and set down slowly and cautiously.
No special bores or threads are provided for transporting the gear unit. There are, however,
many threaded fastening holes in the gearbox where eye-bolts can be screwed in, thus ena-
bling safe transportation and handling.
It must be assured that no loads (particularly no bending stresses) act upon the spindle and the
gear unit.
Improper transportation of the gear unit can cause damage to the output-shaft bearing or the
spindle drive resulting in a considerably reduced service life of the gear unit and the spindle.

4. Preparing the installation
Installation work may be carried out only by qualified or specially trained personnel.
Inspect the gear unit for outside damage and soiling. A damaged or soiled gear unit must not
be installed or operated.
Cleaning with high-pressure cleaners is not permissible. It leads to the destruction of the
seals and penetration of water into the gearbox and consequently to premature failure of the
gear unit.
Do not clean the gear unit, and in particular the area of the seals, with sharp-edged objects
and liquid cleaning agents.
4.1. Check for true-running at the spindle of gear units with rotating spindle:
In order to make sure that there is no transport damage, check the spindle for true-
running before installing the gear unit in the system!
Position and clamp the gear unit horizontally. Place the dial indicator on a level support on
the workbench and put the measuring sensor on the nut. With motor disconnected, turn the
input shaft by hand until at least one full revolution of the spindle is completed.
Measuring point 1:
Permissible radial divergence (=value indicated by dial indicator): 0.1 mm
Measuring point 2:
Permissible radial divergence (=value indicated by dial indicator) depending upon the spindle
length measured from the front edge of the gear unit:
Spindle length Radial divergence
Up to 500 mm 0.25 mm
500-1000 mm 0.5 mm
1000-1500 mm 0.8 mm
Please contact us, if the permissible radial divergence is exceeded.

5. Mounting
Mounting work may be carried out only by qualified or specially trained personnel.
Warning!
Rotating or straight moving parts may catch pieces of clothing, hair and members of
the body and injure persons. The installation must ensure that persons cannot be en-
dangered by any rotating or straight moving components.
Screw-jack gearboxes or any individual components must always be mounted free from ten-
sions.
5.1. Mounting the set of limit-switches for gear units with rotating spindle:
The limit switches are suitable both as operating limit switches and as safety limit switches.
The mechanic limit switches are equipped with forced mechanical disconnection. This feature
permits their utilisation as safety limit switches in accordance with the accident-prevention
regulations of the German professional association.
The protective tube is delivered with the necessary bores.
If additional holes are to be drilled after delivery, the following points are to be observed:
•Arrange the bores so that after the assembly they will be covered by the plate in
which the limit switch is screwed in.
•Do not use any extended slotted holes, because they could cause an unacceptable
reduction of the strength of the protective tube.
•Clean the tube from chips after drilling and remove any burrs on the inside and the
outside of the holes.
•The protective tube of the 100kN gear unit has a welding seam on its inside. This
must be fitted into the recesses on the protective-tube flange and the twisting protec-
tion.
•Always use the same screw length and insert the spring washer when mounting the
protective tube again. If screws are too long, they will block the spindle and if they are
too short, their retaining strength is insufficient.
Screw the limit switches into the plate as specified. Proceed according to the table below and
as shown on the drawings 1 and 2. Tighten the nut at the limit switch only slightly.
Fasten the plate with the clamp on the protective tube. The limit switch must sit in the middle
of the bore. Tighten the screws only slightly.
Then start up the gear unit as described under step 7.

After installing the gear unit in the system check whether the limit switches function as re-
quired. The switching point can be changed by moving the limit switch in the bore of the pro-
tective tube in axial direction.
Do not reduce the screwing depth! The mechanic limit switch is provided with mechanical
forced disconnection. The installation dimension is co-ordinated with this switching point.
The limit switch can be screwed in slightly further, if the required switching point cannot be
reached by axial displacement.
When using a mechanic limit switch, be careful not to exceed the maximum switching range.
In the case of an inductive limit switch, make sure that it does not project into the protective
tube.
After determining the switching positions, tighten the screws at the clamp with an indicating
torque wrench to 3.5 Nm and lock the nut of the limit switch .
When used in areas with explosion hazard, only limit switches meeting the ATEX require-
ments may be used. The limit switches of the standard program are not suitable there.
When used in areas with explosion hazard, suitable corrosion protection (e.g. greasing) must
be provided, if there is a risk that mechanical sparking may occur.
When used in areas with explosion hazard, use corrosion-protected screws, if there is a risk
that mechanical sparking may occur.

5.2. Mounting the fork link/link-rod head for gear units with non-rotating spindle:
The fork link / link-rod head are usually supplied unassembled.
Screw the fork link / link-rod head onto the spindle end and adjust according to the mounting
position. After the installation there must not be any tension between fork link / fork-rod head
and the turning-out protection.
The fork link / link-rod head must be connected with the spindle in such a way that the spindle
torque is reliably transmitted. The kind of connection chosen should be checked by calcula-
tion.
When used in areas with explosion hazard, suitable corrosion protection(e.g. greasing) must
be provided, if there is a risk that mechanical sparking may occur.
5.3. Mounting the spindle nut for gear units with rotating spindle:
Spindle and nut must be exactly aligned. Lateral forces and bending moments are not per-
missible. They are responsible for increased wear and tear.
The proper alignment of spindle and nut must be carefully checked in order to exclude any
risk of overheating the spindle drive. This check must be repeated after 10 hours of operation
under operating conditions.
The installation of the nut under the load support must be carried as shown on the following
sketches.

Self-aligning running nuts can counterbalance an existing angle error of max. 3°between
spindle axis and nut screwing face. This can reduce the wear of the nut if the screwing face of
the nut is a welded construction.
Self-aligning running nuts can neither make up for an existing parallelism error between spin-
dles nor for deviations from right angles between fixing surfaces of gearboxes and guiding
devices.
5.4. Mounting the safety grip nut for gear units with rotating spindle:
In the case of gear units with non-rotating spindle the safety grip nut is optional equipment.
Please request our special documentation.
In the case of gear units with rotating spindle the safety grip nut is already mounted at deliv-
ery.
In most cases the running nut must be removed for the installation of the screw-jack gearbox
in the system. When mounting it again it is necessary to readjust the distance between run-
ning nut and safety grip nut correctly. The distance “X” originally set is stamped upon a
nameplate on the gear unit.
5.5. Mounting the flanged-nut swivel bearing / the support for gear units with ro-
tating spindle:
Screw the flanged-nut swivel bearing / the support in the proper position to the flanged nut.
Tightening torque as indicated on the chart below.
Choose the flow of forces, if possible, in such a way that the force passes over the supporting
surface and not over the screws.
When used in areas with explosion hazard, suitable corrosion protection(e.g. greasing) must
be provided, if there is a risk that mechanical sparking may occur.
