contingency

I)Mobilisation of roadable trandsporters only done

during daylight hours

II) Make sure transporters in good conditions priorto dispatch

III)Use realiable subcontractor for mobilisation of

non roadable transporters (PST-Es)

I)Mobilisation done at least 2 days prior to actual

requirement on site

II)Double check paperwork at least 1 month prior

to dispatch

I)Have at least 10 axle lines spare which can be

mobilised at any time

II)Mobilisation done at least 2 days prior to actual

requirement on site

I)Mobilisation can continue with a few flat tyres on

each transporter

II) At least 3 spare tyres are to be mobilised

I)Transporter assembly done in time to allow last

minute dispatch of small parts

II)Insist on f lexibility from independent

subcontractors to use each other's tools/parts

I)Make sure not all transporters arrive at the same

time

II)Carefully plan quantity of assist equipment

required and closely follow up

III)Client to dedicate certain quantity of assist

equipment for this purpose

2)During assembly and dismantling of the

transporters at site

b)Not sufficient assist equipment (eg crane,

forklift) available at site

c) Some transporters get held up at another job

a) Some transporter connection parts are missing

a) Transporters are involved in an accident

contingency


I) Clearly request and monitor the required space

II)Double check space available at least 2 days

prior to positioning date

I)

The supports are to be very precicely positioned

in line for positioning of long trailers with

sufficient gaps

II)Client to have a set of jacks on standby for last

minute required changes

I)Mobilise at least 2 pcs additional beams other

than required for contingency purpose

II)Have sufficient hardwood jacking timber on

standby for last minute adjustments/shimming

I)

Close off the partition involved to be able to

continue job. Complete proper repair after

testing

II)Test all hydraulic systems to maximum pressure

prior to positioning transporters under the decks

III) Mobilise a number of hoses which are mostlikely to give way

IV)Designate a hydraulic hose shop in the vicinity

for quick repairs

e) Major powerpack failure I)Have sufficient contingency built in to be able to

continue the job with one powerpack less

d) Hydraulic hose bursts

During positioning, pick up & testing of the

transporters underneath the cargo3)

a)Not sufficient space under module to position

transporters

b)Module supports are not positioned in a straight

line

c) Not enough supports or support beamsavailable on top of the transporters

contingency


I)Be ready for last minute adjustments of

transporter configurations

II)Be ready to mobilise additional transporters incase problem can not be solved by change of


III)

Client to double check and closely monitor their

weight control reports and center of gravity

calculations

IV)

Be ready prepared for last minute changes in

the hydraulic grouping of the transporters'

suspension cylinders

I)Initially plan transporter loading to maximum

90% of maximum loading

II)

Be ready to mobilise additional transporters in

case problem can not be solved by change of


III)

Client to double check and closely monitor their

weight control reports and center of gravity

calculations

I) Have spare computers/parts on standby on site

II) Have electronic expert on standby on site foremergency cases

III)Continue testing at manual override mode and

make proper repair prior to transportation

g) Module heavier than expected

h) Powerpack on-board computer failure

f)Center of gravity not in position as expected

resulting in overloading of certain transporters

tyre after testing

II)Check tyre pressures prior to placing

transporters underneath the decks

III)Check transporter path for sharp objects prior to

placing transporter underneath the decks

I)Close off the partition involved to be able to

continue job if feasible , if not replace the hose

II)Test all hydraulic systems to maximum pressure

prior to positioning transporters under the decks

contingency


I)Have at least 1 control box on standby for each

system (being Goldhofer and SPMT)

II) Have sufficient connection cables on standby

III)Have electronic expert on standby for

emergency cases

I)Continue with the flat tyre if feasible, if not

change it

II)Check tyre pressures prior to placing

transporters underneath the decks

III)Check transporter path for sharp objects prior to

placing transporter underneath the decks
