Structure and use guidance
The MMlifting jack serves for lifting or lowering components
and loads with assembly works on building sites. Only vertical
loads (in the plumb line) must be carried.
With the lifting jack e.g. steel girders or wood purlins can be millimeter-exactly
aligned. The weight is turned up or down by means of crank within selflocking
spindle transmission. The lifting jack is equipped with swivel rollers, so that it
can be easily moved to the load bearing position when not carrying a load.
When loaded, it must (only) be moved in longitudinal direction, which enables
precise alignment of components.
General note
Only components in perfect status and original equipment may be used.
This must be checked before use. The lifting jack must not be used until
it has been repaired appropriately.
The lifting jack is to be used only according to the intended purpose.
Any other improper use is prohibited.
The rules for the prevention of accidents are to be observed.

Building up the lifting jack
During erection and dismantling of the lifting jack, there is an increased risk of crushing for
fingers and hands. The following steps should be performed by 2 people, and the compo-
nents to be moved are to be touched and handled from the outside.
Do not reach into gaps and hinge openings.
Lifting jack in the folded down status.
Before building up all swivel rollers must be fixed with brakes.
Now the stand is erected and fixed by attaching
the struts onto the forked bolt on stand and
carriage.
Caution, the boom is still freely movable and
there is increased risk of crushing between the
boom tubes!
Subsequently the spindle is swivelled up and
introduced to the slot accommodation of the lateral
strap of the load arm. Now the heading fork can be
put in, even possible with adapter.
The lifting jack is ready for action.
The disassembly takes
place in reverse
succession.
Subsequently, the load arm and the stand are connected
with the locating pin. The locating pin becomes secured
with the quick lock pin.
The load arms as well as the stand are folded up.

Use and operation
Important:
•The lifting jack may be set up only on horizontal-even,
capable of foundation.
• The weight, e.g. a steel girder or a wood purlin, will be put
on the heading fork of the lifting jack or hooked into the
loop of the boom. The borings in the heading fork provide
the possibility of fixing the hung up load.
• The brakes of the swivel rollers must be fixed beforehand.
The swivel rollers should point to the outside once fixed,
to realise maximum contact width.
• If loads placed or suspended are to be moved, this must
be done in the deepest possible position of the boom.
When moving with lifted load there is a risk of turning
over!
• Moving with lifted load is only permissible in lifting jack
longitudinal direction! Risk of turning over!
• It is recommended to sweep off the surface on which the
lifting jack is moved under load. Even small stones hinder
the swivel rollers of the loaded device.
• Another recommendation is to additionally secure the
lifted load with scaffold jacks placed underneath during
movement.
The crank for infinite lifting and lowering of the load can
be attached on both sides of the spindle gear.
Its length is adjustable, so that a large radius (lever arm)
for lifting, or a small radius (faster) for unloaded
movement can be set.
With the plug-on of the adapter, which is otherwise
between the two pipes of the stand, it is possible
to raise up the work height of the lifting jack
by 0.25 m to 3.00 m.

Lifting a load off the ground
A fundamental requirement for intended lifting with the lifting jack is
the lifting jack carriage being below the load.
If the load to be lifted is on the ground (in the
picture a carrier HE-B 300 for example), this must
be initially lifted by approx. 30 cm and placed on
a suitable base (e.g. squared timbers). This is the
only way to ensure that the carriage of the lifting
jack can move under the carrier for the actual lift.
Using one lifting jack
When working with one single lifting jack it is
necessary to take up the carrier (or similar) to be
lifted in the centre of gravity.
In this step the carrier is hooked into the load loop
with respectively load-bearing sling gear to lift it
to the respective height for take up by the
heading fork. This height depends on whether the heading fork is directly inserted into the mounting of the lifting jack or
whether the adapter (order no. 12374) is used for a total lifting height of 3.0 m (see below). The lifted carrier is to be placed
down on an appropriate load-bearing support (e.g. scaffold jacks).
Once the heading fork and adapter, if required, are installed, the carrier (load) is to be lifted again in the centre of gravity.
Borings in the plate of the heading fork enable additional mounting of the carrier. It is recommended during the lift to
always track the support to provide an additional safety device against tilting and falling. The lifting jack must only be
moved in its longitudinal direction with a lifted load!

Using two lifting jacks
When using two lifting jacks in pairs, the maximum
load bearing capacity increases to 2 x 450 kg = 900 kg
If two lifting jacks are being used, these are to be positioned symmetrical to the centre of gravity, as far towards the
end of the carrier (load) as possible. Each lifting or lowering movement must be performed synchronously and
uniformly, tilting of the carrier is to be avoided.
In this step the carrier is hooked into the load loops with respectively load-bearing sling gear to lift them to the
respective height for take up by the heading fork. This height depends on whether the heading fork is directly inserted
into the mounting of the lifting jack or whether the adapter (order no. 12374) is used for a total lifting height of 3.0 m
(see below). The lifted carrier is to be placed down on an appropriate load-bearing support (e.g. scaffold jacks).
Once the heading fork and adapter, if required, are installed, the carrier (load) is to be lifted again SYMMETRICAL
to the centre of gravity. Borings in the plates of the heading forks enable additional mounting of the carrier. It is
recommended during the lift to always track the support to provide an additional safety device against tilting and
falling. The lifting jacks must only be moved in their longitudinal direction with a lifted load!
Putting down the weight takes place in reverse succession.

Technical subject to change 18.08.2014
Before each employment is to be considered
• Visual check of the lifting jack on complete assembly and functional test of the spindle transmission.
• Defective or worn parts must be changed before using.
• Examine the spindle, the spindle transmission as well as the bearings for sufficient lubrication:
- lubricants of the spindle as well as the
spindle transmission with machine fat
-oils of all bearings
Storing the lifting jacks
In the folded up status several lifting jacks could be stacked with the
help of the plug-on handles (Order no. 12351) one above the other.
Altogether max. 5 lifting jacks may be stacked one above the other.
