3. Protect the spindle jack from dust and dirt on the job site and during the
transport. Always grease the spindle jack with before any job.
Connect the equipment to the power supply.
Connect the data-ram cable to the electrical cabinet (Figure 1).
Connect the junction box cable to the electrical cabinet (Figure 2).
Unscrew the bolt (left) which holds the cable feeder spool (Figure 3).
Unscrew the bolt (1 rev. maximum) before mounting the lifting beam on
top of the jack and screw the bolt fix during transport (Figure 4).
Screw down the mini-spindle’s to be sure load that is been transferred
into the roller drives by the spindle only before a lifting operation.
Screw up the mini-spindle’s until the alignment strips hits the frame
during transport (Figure 5).

4. Each individual project need to have a Lift Plan, this plan should be made
by a professional and experienced engineer.
The engineer must make all calculations to check the following:
Ground loading
Foundations
Centre Point of gravity of the load
General Stability.
Check slings and shackles.
Adopt all local safety and environmental regulations.
Only experienced and trained operators can and may handle or operate
the equipment.

5. Maximum Acceptable Load:
It is generally recommended to obtain a certain safety to the rated
capacity of the equipment the manufacturer’s advice is the 75% rule:
Although the rated capacity of the units is specified as SWL per unit, the
client needs to take notice of the following effect.
Any given load can have so much torsion resistance that the actual load
can be taken by only 3 units because of variation of travel by the units
against each other.
Also in case of power loss to one of the units or technical failure the
load may be taken by only three units. It is recommended to design the Lift
Plan with notice to this possible effect.

6. Side Loads on the object or equipment are to be avoided at all times, these loads
can lead to instability and may be the cause of accidents, damages to the equipment or
object or injury or death.
Side loads can be, amongst others, initiated by the following factors:
Not Vertical plan commissioning of the units.
Non-parallel commissioning of skid tracks or units.
Wind loads on the configuration.
Asymmetrical loading of the object.
Allowable side loads:
Vertical load is a depending factor to the acceptable side load that can be accepted
on the units. The allowable side load can be calculated with the following formula:
Longitudinal: 200 x load in kN = max. side load
Height COG in mm
Side: 125 x load in kN = max. side load
Height COG in mm
Example:
Object is 400 kN to be lifted on 4 units
COG is at 4000mm
Maximum side load in longitudinal direction per unit =
200 x 100 kN = 5 kN/unit
4000

7. At first sight it looks like a normal operation but if you take a closed look you can see number of things that are not as
they should be:
This transformer must be unloaded from a trailer (Figure 6)
The gantry is fully extended due to the very long slings that are used (Figure 7)
The slings are connected on to the bottom of the transformer. The result is that COG will be above on the transformer
attachment (Figure 7).
The trailer is placed too much to the left side with relation to the beam attachments. The results will be that the object
will swing to the right at the moment it will come loose from the trailer (Figure 7).
No skid tracks are used the rollers of the units are standing on paved ground that is not able to resist the point loads
that will occur. (Figure 7)
The operators are standing in between the units and have no oversight on the general situation (Figure 8)
See the transformer swing to the right at the moment the front side of the transformer comes loose from the trailer.
(Figure 8&9)
Disaster is now complete.
Notice the operators (all three) still have no clue what is going on.
The man that was operating the trailer is gone. From his position it was clear what was going on and had a chance to
leave the drop zone.
