1.10 Installation of the Guldmann lifting hanger before use
Lifting hangers from other
manufacturers
Guldmann shall not be liable for faults
or accidents that may occur as a result
of using lifting hangers made by other
manufacturers.
If there is any doubt about the selec-
tion or use of a lifting hanger, please
contact your supplier.

1.11 Lifting sling
A lifting sling with four to eight lifting straps designed for mounting on hooks
should be used when using a Guldmann lifting hanger.
Slings made by other manufacturers
Guldmann shall not be liable for faults or accidents that may occur as a result
of using lifting slings made by other manufacturers.
If there is any doubt about the selection or use of a lifting sling, please
contact your supplier.
Guldmann shall not be liable for faults or accidents due to incorrect use of the
lifting sling, or for reasons of inadequate attention on the part of the carer or
user.
Attaching the lifting sling
Place the straps from the lifting sling on the hooks on the lifting hanger. Start
with the uppermost set of straps (from the back) and then take the lowest set
of straps (from the legs).
Lifting hanger, 4 attachment points
Caution!
Be careful when attaching the lifting sling’s straps on the hooks. Check
that the straps have been correctly placed in the lifting hanger’s hooks.

hooks (Fig. 1).
Fig. 1
Lifting to and from a seated position
When lifting a user from e.g. a wheelchair, move the GHZ towards the person
to be lifted. The lifting hanger should be at the same height as the user’s
chest and should not be moved further in over the user than to approximately
mid-thigh position.
Place the lifting hanger parallel to the user’s shoulders.
Place the lifting sling behind the user’s back between the back of the chair
and the user’s back. The center marks of the lifting sling should follow the
user’s spine.

Lead the leg straps along the outer sides of the user’s shins and beneath
the thighs between the hollow of the knees and the hip joints. Cross the leg
straps in front of the user.
All four lifting straps are now ready to be attached. The lifting sling can now
be mounted on the lifting hanger.
Lifting to and from lying position in bed
Bring the lifting hanger over the centre of the person to be lifted. Place the
lifting hanger parallel to the user’s shoulders.
Turn the user onto his or her side. The Basic High sling should be placed so
that its top is at the same height as the top of the user’s head. Now position
the sling over the user so that the center marks follow the user’s spine. Turn
the user onto his or her back and pull out the remaining part of the lifting
sling. Place the leg straps beneath the user’s thighs and cross them. All four
lifting straps are now ready to be attached and the lifting sling can now be
mounted on the lifting hanger. It is an advantage to elevate the head of the
bed so that the user is sitting up.
For further information, please refer to the user manual for the lifting sling in
question.
Important!
Only persons who have received competent instruction regarding the use of
lifting equipment and tting of slings should use the hoist.
Plan the move. Avoid leaving the user in the lifting sling unattended.
The hoist lifts quickly and powerfully. Before lifting, check that the user is
completely free of his/her surroundings. The user’s head, arms, hands and
feet must not be in danger of becoming trapped. Be careful with any tubes
and wires that are attached to the user. The user should not hold the lifting
strap during the moving procedure as there is a risk of crushing between
the strap’s hook and the hoist. Check that the hand control and hand control
cable is free of hanger, patient and other object before the hoist is activated
up or down moved.
If the hoist is used correctly, the user should only be lifted to the extent that
she/he is clear of the surface and should be moved at this height.

Note: There must be a load on the lifting strap corresponding to the weight of
Guldmann’s lifting hanger before GHZ’s lowering function will operate.
Charging / connection
GHZ is recharged when the hand control is placed in the charging station.
Always leave the hand control in the charging station when GHZ is not in use.
This guarantees GHZ functionality and maintains the battery to ensure a long
lifetime.
The power supply must be connected and switched on before charging can
take place. A green indicator lamp on the power supply indicates it is con-
nected and switched on.
Tilt the hand control and place it on the two pins on the charging station.Then
push the rubber handle into the opening of the charging station. A click indi-
cates that the hand control is placed correctly.
When the hand control is correctly placed in the charging station, you will receive
an acoustic signal of 3 beeps. This means that the hoist is now charging.
The indicator lamp on the bottom of the hoist turns yellow if the charge status
becomes low. The GHZ then has a limited number of lifts available at a time
and must be recharged.
Placing of the hand control
When GHZ is not in use the hand control must always be placed in the char-
ging station. The hand control can also be placed on the lifting hanger if this
is necessary in connection with a transfer.

2.04 Safety functions
The emergency stop and emergency lower should only be used in the event
of hoist failure or fault. The fault must be identied and rectied by a suitably
qualied technician before the hoist can be taken back into use. The Emer-
gency stop should not be reset unless by a suitably qualied technician.
Under no circumstances should the user attempt to reset and continue to use
the hoist where the emergency stop has been activated due to fault or failure.
The hoist issue should be referred for service and rectication by a suitably
qualied technician.
Emergency stop and lowering strap
The red strap has the following functions:
• One pull: Emergency stop is activated.
• Constant pull: Emergency lowering is activated.
Emergency stop
If the GHZ does not stop/react to the hand control when the GHZ is in
use, pull the red strap and the lifting/lowering functions (except emergency
lowering) are deactivated. When the emergency stop is activated, the hoist
will not function. The green lamp is switched off.

14
