SAFETYGUIDELINES
The assemblyinstructionsmustbe read and understood beforeset-up oroperation.The crane mayonlybe
assembled inaccordancewiththe manufacturer’sinstruction manual.
The GF-8Crane mayonlybe set-up oroperated bytrained and experienced personnel.Toavoidmisuseby
untrained personnel, the crane shouldbe dismantled when not inuseorundersupervision.
Forfurtherinformation on the qualificationsrequired fortest personnelpleaserefertoBGV1, §33 and §34.
The crane maynotbe assembled oroperated undertheinfluenceof alcohol,drugsoranyotherintoxicating
substances. The respectiveprotectiveclothing e.g.gloves, shouldbe worn.
The manufactureracceptsno liabilityfordamagesorinjuriesforincidentsoraccidentsoccurring due to
negligencebythe crane operatorormisuseofthe crane ordisregarding the instruction manual..
Beforeassembling the crane ensurethatthe ground surfaceisstableand cannotgiveway.The ground
surfacemust be stableenough tosupport atleast 1000 kg/m2= 2200 lbs/ sqyard.
Crane operation isonlyallowed withsolidtires. Usewithpneumaticwheelsisnot allowed.
The crane dollymustbe levelatall times.Ifnecessary,levelthe crane withthe provided levelling legs
ensuring thatthe levelling legscannotsinkorbreakthrough the surfaceand aresupported enoughwere
necessary.Whetheroperating ormoving the crane ontrackoron asolidground surfaceitisessentialthat
the trackorsurfaceiscompletelylevel,stableand free fromobstructions.
Whenoperating the crane on track,ensurethatthe track islevel,properlylaid,constructed and supported.
The correctunderlaymustbe used toensurethatthe track and underlayaresecuredagainstmoving,
slipping and collapse.Ensurethatthe underlaymeetsthe specifiedsupportand stabilityrequirements.Only
GFMTrack orcomparabletrack systemswithapayload capacityof 1200kg/2640lbsand amaximumtrack
runnerdistanceof 640mm/25inches(measured insideedge toinside edge)maybe used.Extremecaution
must be used if tracking oncurved track(no fasterthan aslowwalking pace).
Useofthe crane on insertvehicles,cameracarsoranymotorised vehicleisnotallowed.The manufacturer
acceptsno liabilityfordamagesorinjuriesforincidentsoraccidentsoccurring due touseofthe crane on
insertvehicles, cameracarsoranyothermotorised vehicles.
Changing weatherconditionsshouldbetaken intoconsideration.The crane mustbe taken outofoperation
beforethe operationalwind speed reaches40kmh. /25mph.See page 39.
The completelift and panning range ofthe crane mustbekeptclearofobstructionsatall times.Asafety
clearanceof 0.5m/ 19"tosurrounding objectsand 1m/39”topersonsmustbe observed on allsidesof the
crane during operation.
The crane maynotbe used inthe directvicinityofhigh voltage powercables.Toavoidaccidentsdue to
misuseinthevicinityofhigh voltage powercables,SafetyGuidelines(especiallyVBG1and 4)aswell as
VDEregulations(especially0105 part100)mustbe adhered to.Ifthe nominalvoltage cannotbe
determined, aminimumclearanceof 5m/ 16ft must be kept at alltimes.Failing todo socan causefatalities.

sudden,abruptmovementsorlean outoverthe side ofthe platform.No looseobjectsmaybe stored or
placed on the crane platform.
Beforethe counterweightsareremoved fromthe bucket, ensurethatthe platformisresting on the ground or
alternativelysupported byan appropriatestableunderlay.Graduallyremovethe counterweightsbefore

The manufacturerstechnicalspecificationsand limitsmustbe adhered toatall timesand inno way
exceeded.Adding extracounterweightbyplacing itontop ofthe couterweightbucketoron anyothercrane
part isstrictlyforbidden.
Inthe interest of safecrane operation abrupt, sudden movement of the crane shouldbe avoided.
Onlyoriginal accessoriesmanufactured byGFMmaybeused withthe crane.

GeneralAssemblyProcedure–GF–8
Before andduringassemblyobserve the SafetyGuidelines.
For all GF-8 Standard-Versions:
1. Securethe base dollyso that it cannot move orroll.Lock allwheelbrakes. Move the
steering rod towards thecentreof the dollyorremove itso that theset-uppersonnel
do not trip overit.
2. Forthe Standard-Versions 1to 8boltthe90cmcrane mountingcolumnto the base
dolly(pivot height 154cm). Make sure that the 4 locking bolts arelocked securely.
Tip:The carrying handleon thebazooka shouldpoint away fromthe steering end
of dolly.

locking nuts and bolts. Make sure that the4 locking bolts arelocked securely.
Asan optiona3stage columnisalso available.It consists of2x30cm/1ft column
extensions and a60cm/2ftMounting Column. Assemblethe columnextension

3. ForStandardVersions 9to 18 werecommend using the 4telescopiccolumn
supports. In smallerversions they arenotrequired but using themdoes increasethe
columns stability.Tomount the supportsconnect the groovedend to theconnection

Tip:Shouldthe columnnot have the 4connections forthe columnsupports, an
adapteris availble. It is connected to the columnbetween the pan bearing and the top
of the column. Todo so the pan bearing mustbe removed by unscrewing the 6
screws. The adaptermust be mounted inlineto the connections on the base dolly
with the adapterring connectorspointingtowards the base dolly. The originalscrews

4. Located on the middle section are 2 tilt friction locks which may be used to lock the tilt
during set-up. Set the pivot armat 90° to the centrepostand lock these friction locks
which can be found on the leftandrighthandside ofthemiddle section. Mountthe
middle sectionon the mounting column. Lock the locking screwtightly.
Tip:A12mm Allen key canbe found inthe mounting column’s handletobe used

5. Connect the 2sections of therigging harness to the middlesection of theGF-8.
Ensure that the 4 locking bolts are fastenedtightly.
6. Connect thecrossbarto stabilize therigging harness.Ensurethat the 2locking pins
areinserted fully
7. ForStandardVersions 1to16 connect the 127cm/4ft section tothe middlesection.
ForStandardVersions 17 and18 connect the 150cm/5ft section to the middle
section. Slipthe connectionflanges into each otherand securewith the provided
safety pin.
Connect therespective127cmor150cmparallelogramrod tothe middlesection,
mount the slidingweightand securewith thelocking screw.Connect therod tothe
angle adjusterand secure itwith asafety pin at each end. Othershorterversions can
be built by using the 100cm/ 3’ 3”or150cm/ 5’ extension and its parallelogramrod.
Tip:The angleadjusterhas an integrated leveller.Byturning it, the verticalplate
on the angleadjustercan be setto aperfect right angle. Correctsetting of the angle
adjusterenhancesthe crane’s balance.
Tip:Toavoidthe sections jamming orgetting stuck make surethat thesections
arejoined parallel.Using asmallamount of lubricant also helps. Wesuggest rubbing
the joints with an oiled rag.

For all GF-8 Xten-Versions:
With the exceptionof afewsteps, the assemblyof the XtenVersionsareidenticalwith
those of the Standard Versions. However, the followingpoints should befollowed:
· All Xten Versions require a pivot height of 184cm/ 6ft as follows:
· 30cm/ 1ft Column Extension and 90cm/ 3ft Mounting Column
· 2 x30cm/ 1ft column extensions and a 60cm/ 2ft Mounting Column
More details can be found on pages 3.
· The Mounting ColumnforallXten Versions(1to 8)must be supported with the 4
Telescopic Column Supports. Moredetails can be found on page 4
· AllXten-Versions (1to8)requirethe Large RiggingHarness withthedouble
turnbuckles.An example of the assembley can be found on page 5.
