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.

5.6. Mounting the mating bearing flange for gear units with rotating spindle:
Hold the mating bearing flange against the spindle end and mount it by tapping slightly with
the plastic hammer.
Rotate the bearing and check for easy running.
Screw it to the system. Tighten the screws as stated in the table below.
Choose the length of the screws in such a way that the available depth of the thread is used
as completely as possible.
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.

5.7. Mounting the bellows:
When used in areas with explosion hazard, it must be ensured that the bellows does not
come in touch with any attachments and does not brush against anything during operation, in
order to avoid electrostatic charging.
Measure the electrostatic charge.
Gear units with non-rotating spindle:
The bellows is attached at the gear unit and at the spindle mounting flange. It must still be
fixed, however, to the fork link or the link-rod head after they are mounted.
Mounting with fork link:
Slide the Delrin sleeve over the fork link and push the flange of the bellows over it. Fix with a
hose clamp. Make sure that the bellows is not twisted.
Mounting with link-rod head:
Slide the split Delrin sleeve with the O-ring over the link-rod head and push the flange of the
bellows over it. Fix with a hose clamp. Make sure that the bellows is not twisted.
Gear units with rotating spindle:
In the case of gear units with rotating spindle one bellows is attached to the gear unit and the
other one is enclosed loosely because the nut must be removed for the installation of the
gear unit in the system. The bellows can be fixed only after the gear unit is installed in the
system. See also Chapter 7.5.
Depending upon the mounting situation, supporting rings are provided in the bellows in order
to prevent the bellows from touching the spindle. They must not be removed!

5.10. Mounting the input flange:
The input flange is usually already mounted when the unit is delivered.
After a removal we recommend to proceed as follows for reassembling:
Before attaching the input flange clean all contact surfaces.
Insert the input flange into the gear centring piece and tighten the screws at first only
slightly.
Then tighten the screws uniformly by turning them alternately crosswise. Tightening torque as
shown in the table below.
Choose the length of the screws so as to make optimal use of the available depth of thread.
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, the opening in the input flange (for tightening the
fixing screw for the coupling) should be mounted so that it looks to the side or downward.
When used in areas with explosion hazard, improper installation can lead to unacceptably
high temperatures.
When used in areas with explosion hazard, use corrosion-protected screws, if there is a risk
that mechanical sparking may occur.

5.11. Mounting the drive coupling:
If the drive coupling is supplied by ATLANTA, it will usually be enclosed separately.
Mount and fix the coupling as described in the enclosed operating and mounting instructions
of the coupling manufacturer.
When used in areas with explosion hazard, only couplings meeting the ATEX requirements
may be used.
Observe the references in the operating conditions of the coupling!
Choosing unsuitable couplings or improper installation may increase the ignition risk.
The maintenance intervals specified in the operating conditions must be strictly observed!
Check for true-running after 10 hrs of operation under operating conditions.
•Torsionally flexible ROTEX claw coupling: at the large hub diameter
•BoWex fast flexible coupling: at the hub diameter.
Recommended mounting procedure:
•Clean all contact surfaces and coat them with a thin oil film before mounting.
•Slide the coupling halfway onto the motor-shaft.
•Tighten the threaded pin of the coupling and secure against loosening (e.g. with Loctite

5.12. Mounting the motor:
Mount and attach the motor as described in the enclosed operating and mounting instructions
of the motor manufacturer.
When used in areas with explosion hazard, only motors meeting the ATEX requirements may
be used.
Observe the references in the operating instructions of the motor!
The choice of unsuitable motors or improper installation may increase the ignition risk.
When used in areas with explosion hazard, use corrosion-protected screws, if there is a risk
that mechanical sparking may occur.
We recommend to proceed as follows::
•Before attaching the motor clean all contact surfaces and coat them with a thin oil film. In
order to reduce the danger of fretting corrosion it is also possible to use a suitable special
grease on the motor-shaft, e.g. Klüberpaste 46MR401
•Optimal centring of the motor is achieved with the motor-shaft arranged vertically down-
ward.
•Slide the motor fitted with the coupling onto the input shaft of the screw-jack gearbox in
such a way that the coupling nut and the key of the screw-jack gearbox are aligned. (Ob-
serve the coupling operating instructions).
•The motor must slide on easily. There must not be any gap between the motor and the
drive flange.
There must not be any foreign matter on the drive flange.
•If necessary, rotate the motor around the motor axle until the fixing holes of motor and
flange coincide.
•Screw motor and drive flange together. Tightening torque acc. to the table below.
Choose the length of the screws so that maximum use is made of the available thread
depth.
•Tighten the threaded pin of the coupling through the opening in the drive flange and se-
cure against loosening (e.g. Loctite 243) in order to ensure reliable axial locking.
When used in areas with explosion hazard, check the threaded pins locking the coupling axi-
ally, after 10 hours work under operating conditions.

Use only calibrated torque wrenches! If the tightening torque is too low, the required torque will not be
transmitted. If the tightening torque is too high, the screws will be overstrained and become useless.
Secure screws against loosening (e.g. with Loctite 243).

5.13. Mounting the handwheel
The handwheel is usually supplied unmounted.
The handwheel must either be firmly connected to the input shaft or removed for motor driven
operation. The connection chosen has to be checked by calculation.
Ensure that no persons may be endangered by a rotating handwheel.
When used in areas with explosion hazard, it must be ensured that no parts can fall onto or
rub against a rotating handwheel, in order to avoid overheating, friction or sparking.
6. Electrical start-up:
Only qualified or specially trained personnel may carry out the connection of the elec-
tric components.
The operating and maintenance instructions of motor and brake must be strictly ob-
served.
It must be ensured that an overload protection device limits the motor torque to 200% of the
motor torque required for raising the nominal load.
The power and brake connections for direct operation from the mains are shown on the en-
closed circuit diagram (paragraphs 12 and 13).
In order to avoid interference with the brake control the brake leads must not be laid in the
same cable together with clock-pulse controlled power leads.
In order to avoid interference with motor protection devices (temperature sensor, coil thermo-
stats) unshielded supply leads must not be laid in one cable with clock-pulse controlled power
leads.
In the case of motors powered by frequency converters the operating and maintenance in-
structions and the relevant wiring instructions of the converter manufacturer are to be strictly
observed.
We strongly recommend to provide for S-shaped ramps at the converter!

7. Mechanical start-up:
The start-up may only be carried out by qualified or specially trained personnel.
The forces and cycle times taken as the basis for the layout must not be exceeded, not
even during start-up.
Before putting the unit into operation, check whether the layout and the actual loads
correspond!
Caution!
The surface of the gear unit, the spindle and the nut can reach temperatures of more
than 65 °C during operation and can cause burns.
The person putting the gear unit into operation must ensure that nobody can be en-
dangered by hot surfaces.
Warning!
Rotating or straight moving parts may catch pieces of clothing, hair and members of
the body and injure persons. The person installing the gear unit must ensure that per-
sons cannot be endangered by any rotating or straight moving components.
When used in areas with explosion hazard, the person putting the screw-jack gearbox
into operation must ensure that the surface temperature of 80°C is not exceeded on
any of the components. If necessary, he must control the surface temperature.
He must furthermore ensure that no sparking can occur. Rotating or straight moving
parts and those with which they may come into contact are to be protected against
corrosion (e.g. by greasing).
7.1. Test-run of the screw-jack gearbox before the installation:
Before making a test-run the gearbox must be protected against twisting and the torque must
be supported by suitable measures at the following points:
Gear units with non-rotating spindle:
At the mounting flange, the link fork or the link-rod head.
Gear units with rotating spindle:
At the running nut.
Move the spindle or the nut by hand into a medium stroke position.
Operated by the motor, perform one complete stroke. Switch off before reaching the end po-
sitions.
When starting the motor for the first time, the gear unit must not be in an end position be-
cause overshooting the end position would damage components, if the motor rotates in the
wrong direction.

7.2. Installation of the screw-jack gearbox in the equipment:
There are two machined mounting surfaces available with sufficiently dimensioned fixing
holes and threaded holes.
Choose the length of the screws so that maximum use is made of the thread depth.
Choose the flow of forces, if possible, so that the force passes over the supporting surface
and not over the screws.
Ensure tension-free mounting.
Use all threaded holes of the appropriate connecting surface.
Tighten the screws with the required tightening torque (see table).
Additional attachments or alterations at the gear unit require written permission by ATLANTA.
It must be ensured that no persons are endangered by the free, rotating input-shaft end. A
fixed cover guarantees reliable protection.
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, it must be ensured that no parts can drop onto or
rub against the free input-shaft end in order to avoid overheating, friction or sparking.
A fixed cover guarantees reliable protection.
Vertical arrangement of the worm-shaft (vertical input) is only permissible in combination with
an oil-level control shutting off the gear unit in the case of a sudden loss of oil.
When used in areas with explosion hazard, use corrosion-protected screws, if there is a risk
that mechanical sparking may occur.

Before starting the operation, the usable part of the spindle must be carefully greased. Ob-
serve Paragraph 7.3 of the lubricating instructions.
The most favourable mounting position of the worm-shaft (input shaft) with a view to the lubri-
cation of the worm-gear transmission inside the gearbox is laterally or at the bottom. If the
input shaft is situated on top, the driving capacity is reduced by approx.10%.
Avoid the installation with motor hanging downward. Leakage oil could get into the motor in
this position.
7.3. Lubricating instructions for screw-jack gearboxes:
Because of the sliding friction between trapezoidal-thread spindle and nut it is absolutely im-
portant to provide sufficient lubrication there. Insufficient lubrication leads to increased wear
and tear and to the destruction of the nut.
The unit is supplied with an initial lubrication of the trapezoidal-thread spindle sufficient for
approx. 10 lifts.
Optimal lubrication is achieved with our electronically controlled lubricator due to the continu-
ous feed of lubricant. If the unit is operated only rather seldom, it may be sufficient to relubri-
cate it by hand. In the case of long intervals, however, manual lubrication may lead to in-
creased wear at the spindle. We recommend to use a high-grade adhesive lubricant which, if
lubricated manually, should be applied with a brush.
Recommended grease:
Klüber: Microlube GB-0
Texaco: Molytex EP 2
Mobil: Mobilgrease HP
Esso: Beacon EP 2
Shell: Alvania Grease R2
ATLANTA order code for 1 kg Klüber Microlube GB-0: 65 90 002
The electronically controlled lubricator must be put into operation as described in the en-
closed instructions BKI 102.
For the start-up fill the hose by means of a grease gun before mounting. Correct lubrication is
ensured only when the connecting hose is completely filled with grease right into the nut.
For the pressure build-up observe the times specified in the lubricator instructions.
Fastest pressure build-up: all switches „ON“: Pressure build-up in 6-8 hours.
Type of lubricant: Microlube GB0 (Fa. Klüber)
As a result of our experiments we recommend to set an emptying time of 6 months after start-
up and pressure build-up. Within the first few days and weeks the grease supply should be
checked at regular intervals and the emptying time should be adjusted to the individual appli-
cations. The surface of the spindle must always be coated with a uniformly thin grease film. If
there is grease in the protective tube or under the bellows, this indicates that the lubricant
supply is too high. Screeching noises between spindle and nut are an indication for insuffi-
cient lubrication.
The filling in the lubricator must be checked regularly. We recommend to include this work in
a maintenance plan.
When the lubricator is completely empty, it can be refilled for further use. Only the pressure
chamber, where the gas generation takes place and which is supplied by us as a spare part,
has to be replaced. A permanent signal lamp, powered by two standard 1.5 V batteries, sig-
nals that the lubricator is ready for operation.
Please request our instructions BKI 103.
