1.07 The lifting sling
A lifting sling with four to six lifting straps designed
for mounting on hooks with a minimum diameter
of 8 mm/0.3” should be used when using a
Guldmann lifting hanger.
Slings made by other manufacturers
Guldmann shall not be liable for faults
or accidents that occur as a result of
using lifting slings made by other
manufacturers.
If you are in doubt regarding the
choice or use of the 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.
Working with the GH2 hoist
It is only necessary to pay attention to the user’s functional level and the
carer’s technique, as the GH2 hoist makes no special requirements as
regards space or power consumption and runs easily in the rail system.
The user should only be lifted just clear of the underlying surface and
should be moved at this height.
Attaching the lifting sling
Attach the hooks that face the user to the uppermost set of straps (from the
back). Attach the lowermost set of straps (from the legs) to the hooks that
face away from the user.
Lifting to and from sitting position
When lifting a user from e.g. a wheelchair, move the GH2 towards the person
to be lifted.
The lifting hanger should be at the same height as the person’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 centre band of the lifting sling should follow the user’s spine. As for the
slings type Active the strap showing the size of the sling should be opposite
the 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 over each other 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 lifting high back sling should be placed

so that its top is at the same height as the top of the user’s head. Now lay the
sling over the user so that the centre band follows 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 over each
other. 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.
Only persons who have received competent instruction regarding the use of
lifting equipment and tting of slings should start using the hoist.
1.08 Before the hoist can be used
Battery connection
Attach 4-pole plug in accordance with the enclosed
instructions. The measures regarding ESD-safety
are valid in this connection. See point 1.09.
Emergency stop device
The emergency stop device must be reset in order
to connect power to the product. To do this, push
the contact arm, to which the red emergency stop
band is fastened, towards the product until it clicks.
1.09 Power supply
GH2 is equipped with batteries that require regular recharging. The power
supply for charging and the battery charging point must be connected by a
qualied engineer or by the Guldmann Service Team.
The transformer/recharger supplied must always be used.
AC power supply
When the power is supplied via the rails (Midi-rails), an AC transformer
Guldmann type DTS-2420, item No. 937000, must be used. For connection
please refer to the installation guide.
If AC power supply is used (MIDI rails), the hoist will after use be constantly
recharged throughout the length of the rail.
DC power supply
When the power is supplied via the charging station, a DC charger Mascot
type 2240, item No. 937030, must be used. For connection please refer to the
installation guide.
If DC power supply is used (MINI, MAXI and JUMBO rails), the hoist shall
after use be placed in the charging station for recharging. The charging
station is marked with on the rail.
Safety concerning static electricity (ESD)
Service technicians and installers must use an ESD-safety package
consisting of a mat, a ground wire, and a bracelet. The technician/installer
connects the mat to a grounding point, for instance a radiator or a water pipe.
He must then put on the bracelet and connect it to the mat. If the technician

is using a ladder, it is important that the mat is placed on the step on which
he is standing. If it is not possible to nd a grounding point, the mat and the
bracelet must be used as a minimum.
Only then is it allowed to work with the PC Board or components where it is
possible to come into contact with the PC Board.
1.10 The Swing-kit
Note: If you wish to use the Swing-kit with the GH2 hoist, this must be
specied when ordering.
1. Bring the two hoists as close to each other as
possible.
The lifting hanger is attached to the hook on hoist B.
2. Pull out the free strap and hook from hoist A and
attach it to the eye.
3. Pull out the lifting strap on hoist B a little further and
retract the lifting strap on hoist A.
When the transfer swing has been completed there
is no longer any load on the lifting strap on hoist B.
4. Release the hook and strap from hoist B, which
now bears no load.
Return the lifting strap to hoist B until the hook is
needed again.
5. Return the lifting hanger on hoist A to working

1.11 GH2+2 ceiling hoist with built-in drive motor
GH2+2 ceiling hoist with a built-in drive motor operates fully automatically on
the rail system.
When using a GH2+2, please note that the motor uses approx. 1 second to
accelerate and stop the hoist, respectively. Thus, when stopping the unit from
max. speed, the motor must be cut off 10-15 cm before the desired position.
When the hand control is activated for a shorter period of time, it is possible
to position the hoist with a high level of accuracy.
GH2+2 must run on its own power and should not be pulled through the rail
system.
1.12 GH2+2R ceiling hoist with built-in drive motor and infrared remote control
GH2+2R has a built-in drive motor and IR receiver which is controlled by the
IR sender.
With this sender, it is possible to control all the functions of the hoist.
Furthermore, the IR sender can be used to control e.g. switch tracks,
combi-locks and turntables mounted with IR receivers.
The cable-mounted hand control must remain tted to the hoist. This will
ensure that the hoist can always be operated if the IR sender is mislaid
or if its batteries run dry.
In certain cases, an unladen hoist with a drive motor can, due to its low
unloaded weight, have difculty in driving through, for example, switch
tracks, if the switch is not open in the direction in which the hoist is passing.
To provide extra security for unassisted users that the hoist runs smoothly
through the track system, it is possible to mount a friction enhancer in
connection with the hoist’s drive wheels. Friction enhancers cannot be
used in connection with a drive-through charging station.
Friction enhancers are mounted as follows:
1. Move the hoist to the end of the rail, making sure that the drive wheels are
free of the rail.
2. The friction enhancer is placed over the wheels as shown. The long pins on
the friction enhancer must point in the direction of the nearest end of the hoist.
3. Run the hoist into the rail again. Check
that the friction enhancer is functioning by
holding onto the hoist with the drive motor
in operation. The hoist must pull strongly
in both drive directions.

Emergency lowering
If the GH2 hoist breaks down, the electric emergency lowering device can
be used to lower the user safely.
The emergency lowering device is operated by a constant pull on the red
strap which is also used to activate the emergency stop.
If the red strap is not pulled constantly, the emergency stop will be active
rather than the emergency lowering device, and it will not be possible to
operate the GH2 hoist before the unit is reset.
Explanation to labels:
Type B
In accordance with EN 60601-1.
Warning
Before use, cleaning and service read the user manual/technical
documentation.
Description of strap safety device
Overloading the hoist, pulling the strap crookedly, or if the strap is twisted, the
strap safety device will be activated, and the GH2 hoist will be deactivated.
If the yellow mark on the strap is visible, it is not allowed to lift with maximum
load.
2.05 Recharging
When the GH2 hoist is not in use it should be parked in the recharging unit.
This will maintain the batteries and ensure them a long lifetime.
When GH2 is being recharged, the yellow charging indicator on GH2’s infor-
mation face is illuminated. The indicator light ashes while the batteries are
being recharged. The light indicates that the GH2 hoist and the transformer/
charger are correctly connected. The green circle of lamps on the bottom of
the hoist will blink if the batteries are running low – the GH2 hoist will then
be able to lift only a certain number of times, and the batteries must be
recharged.
To recharge the batteries, place the GH2 hoist in the charging unit marked
with the battery symbol on the rail. The batteries in a GH2 hoist installed in
a MIDI rail will be constantly recharged throughout the length of the rail.
