Selection of jacks
Symbols used:
F
= Force (N) (1 tonne = 10 000 N)
v
= Lifting speed (mm/min)
s
= Pitch of lifting screw (mm)
n
= Required input speed (rpm)
i
= Ratio of worm gear set
ED = Intermittence factor (%)
Pd = Running power of screw jack (kW)
Ps = Starting power of screw jack (kW)
PED = Thermal power (kW)
PMnom = Nominal motor power (kW)
PMst = Starting power of motor (kW)
PMax = Max allowable input power of
screw jack (kW)
ηd = Running efficiency of screw jack
ηs
1. Select a screw jack where the nominal
force is larger than the required force.
(See "Technical data").
2. By compression load check stroke
length for bending according to Euler I,
II or III (See compression load tables)
3. Check in Power rating tables that the
max allowable power or torque is not
exceeded.
4. Selection of one screw jack
Calculate the running power (Pd) and
starting power (Ps). Pd is stated in
tables, see note 3 or calculate as follows
Fxv
Pd =
ηd x 6 x 107
= Starting efficiency of screw jack
Fxv
Ps =
To calculate a screw jack you must at
least know the force (F) to be moved and
the lifting speed (v).
There are three types of standard format
Benzler mechanical jacks.
I. BD/BDL
Screw jack with single start trapezoidal
lifting screw available in 8 sizes, as
standard.
This is the most frequently used screw
jack, suitable for low lifting speeds (up
to 2400 mm/min), competively priced.
II BD/BDL
Screw jack with double start trapezoidal lifting screw available in 8 sizes,
as standard.
Higher lifting speeds can be obtained,
compared to single start lifting screw,
with increased efficiency, a brake must
be included in the system, as they are
not self sustaining.
III BDK/BDKL
Screw jack with ball screw lifting screw,
available in 4 sizes as variants.
This type is suitable for high lifting
speeds.
Owing to the higher overall efficiency,
it is suited for applications with high
degree of utilization required. (High
ED).
Brake must be included in the system,
as they are not self sustaining.
ηs x 6 x 107
ηd = running efficiency (see "Power
rating tables")
ηs = starting efficiency (see "Technical
data")
5. State the intermittance factor
ED in %/hour
Example: 12 min/hour = 20%
6. If ED is other than 20% check on page
23 or 38 that the thermal power PED is
not exceeded.
The selection of jack is correct if
PED > Pd (Pd see note 4).
7. When selecting screw jack type BDL
and BDKL check critical spindle speed,
see page 24 or 38.
8. Only screw jacks type BD can permit
side forces (see table page 25).
9. Selection of motor:
I Check that
Nominal motor power PMnom > Pd
(Pd, see note 4)
II Check that
Starting power of motor PMst > Ps
(Ps, see note 4)
To determine the starting power of motor,
following formula is used in most cases:
Mst
x PMnom
PMst =
M
Mst
M
= factor stated in motor catalogue
Note: For three phase motor
the factor Mst is normaly 1.8 - 2.5.
M
Consult BENZLERS for further
information
10. Calculate the required input speed

Calculation of multi jack
arrangement
To calculate a screw jack arrangement is
described in a simplified way below.
For a more detailed calculation consult
Benzlers.
1) Calculate the power consumption of
each single jack in the arrangement as
under "4" for single Jacks.
2) Add the power consumption of each
single jack to get the total power consumption, Px.
3) Attention must be paid to the efficiency
of the connecting shaft system and
other components in the arrangement
such as: Worm Gears, Bevel Gears,
Helical Gears, Couplings, Bearings
and normal misalignement when mounting the arrangement.
If this is not possible use the following
arrangement efficiency:
Number of jacks
2
3
4
6-8
Parr =
ηarr
0,95
0,90
0,85
0,80
Px
ηarr
Parr = Total power consumption of
the arrangement
Px = The sum of the power
consumption each single jack
ηarr = The effiency of the arrangement acc to table
4) After calculating design motor power
required, care should be taken to choose a larger motor with a safe working
margin of excess power.
5) By high lifting speeds and high speed
in connecting shaft system, the massmoment of inertia must be taken into
consideration.

Benzlers mechanical jacks have a allowable working temperature range from -30° C to +100° C. At full load the degree of utilization (ED) must not normally exceed 40% per 10
minutes, still not more than 20% per hour totally, in valid at
ambient temperature +25° C.
For other conditions consult Benzlers.

Options
STOP NUT (SM)
STOP NUT (SM) + LIMIT SWITCH (LS)
Stop nuts can be fitted to all Benzler screw jacks, both above
and below the main body.
Benzler jacks can be supplied with limit switches to suit most
applications. Standard is two limit switches and one stop nut.
These must be included when there is an inherent risk of over travel resulting in the spindle becoming disengaged from the worm
thread.
Upper/lower limits can be mounted on the protection tube.
Adjustable limits are also available on request.
1 Stop nut
2 Carrier
2 Protection tube
3 Limit switch
1 Stop nut
3 Tube sleeve
Fig. 31
SAFETY NUT (SHM)
In certain applications the addition of a safety nut may be required. The object of the above is to prevent the load collapsing in
the event of the lifing nut thread failing.
Fig. 32
Load safety direction
Monitoring of the safety gap between the lifting and safety nut
gives an indication of the intermediate wear. When the safety
gap reaches zero the lifting nut has reached its wear limit and
requires changing. In applications where the safety nut is inaccessible, electro/mechanical switches are available to indicate
maximum wear.
1 Safety nut
2 Spacer
3 Worm wheel
Load direction important!
Combinations with other options are restricted. Consult Benzlers
for more information.
Fig.33
30
LOCKED AGAINST ROTATION
For applications where a load is to be raised/lowered and permanent fixing i.e. top plate/clevis, is not practical, the spindle
must be prevented from rotating.
Two options are available:
I) LR - Locked Against Rotation (Tube)
Protection tube manufactured in box section mild steel.
Spindle end complete with nut (sized to suit box section).
1 Gear housing
2 Locking nut
3 Locking assembly (size dependent variant 1)
4 Tube
5 Pin (size dependent variant 2)
II) LRK - Locked Against Rotation (Key)
Jack internals are modified to incorporate a rectangular
key which engages in a precision keyway cut into the spindle
length. Primarily used in precision applications requiring
minimal radial movement.
1 Jack cover
2 Lifting screw
3 Key
Combinations with other options are restricted.

II
Fig. 34
ANTIBACKLASH (ABL)
Where the loading on a Benzler screw jack can be in both tension and compression and the spindle backlash is critical, units
can be supplied with a Back-lash Eliminator comprising of a
modified worm wheel fitted with a secondary nut, allowing contact on both face and flank of driving thread.
Backlash 0.0l-0.05 mm - During operation excessive backlash
can be removed by adjustment of the top cover. The nuts are
separated by a pre-determined gap to eliminate the adjust-ment
of the backlash eliminator when drive thread width has been
reduced by 25%.
1 Worm wheel
2 Dowel pin
3 Adjusting nut
4 Jack cover
Combinations with other options are restricted.

Benzler Universal Joint shaft
Type X-G
Permissible Shaft Misalignment
Universal joint shafts for spanning any distance and for compensating for larger radial offset misalignments.
The element type X is torsionally very stiff, free from play, but
has bending elasticity and is axially and angularly flexible.
Moreover, it is oil-resistant and withstands temperatures up to
150° C.

Lubrication intervals
Normal duty < 1 000 mm/min lifting speed:
Every 30 hours of duty
Arduous duty > 1 000 mm/min lifting speed:
Every 10 hours of duty
Renew grease every 400 hours of duty.
Note: On screw jack type BDL and BDKL the lifting screw shall
always be lubricatled with a thin film of grease.
Mounting and maintenance instructions
1. The jack must not be overloaded.
2. The base, on which the jacks are mounted, should be strong
enough to carry the max. Ioad and should be rigid enough to
prevent swings or turns on the supporting beam of the jack.
3. When mounting it is necessary to make sure that the jacks are
carefully adjusted and that the connecting shafts and the
wormshafts are exactly aligned. The lifting screw or lifting nut
must be carefully aligned to prevent radial forces on the lifting
screw. When jacks, shafts, gear boxes etc. have been connected it should be possible to turn the main driving shaft by
hand (provided that the jacks are unloaded). If there are no
signs of seizure or misalignment, the lifting system is now
ready for normal operations.
5. The lifting screw must not be permitted to collect dust and
sand in the threads. If possible the lifting screws should be
retracted to the closed position when not in service.
6. Maximum wear for types BD and BDL is reached when the
thread thickness of the worm wheel or lifting nut is half worn
out. Worm wheel and lifting nut must then be replaced. For
singlethreaded trapezoid screws the permitted wear is 1/4 of
the pitch. The customer should regularly check that normal
permitted wear is not exceeded.
4. The screw jacks should have a longer length of stroke than is
actually required. Should it be necessary to use total length of
stroke, this must be done carefully. It is important that the lifting screws of the jacks are not screwed beyond the closed
height (see catalogue), otherwise the worm gear could be
severly damaged.
