~he present description relatecs, as indicated i~
the titl~, to a machine ~or cleaning gratings by mean~ of
dl; o~cill~ting ~rm ~or ~yd~aulic weirs of the tYpe use~
for cleanin~ dirt which ~5 deposited on the gratinss o~
hydraulic weirs, essentially when the ~lo~. o~ the water ts
1Q utili~ed for electric power stations.
The m2chani~s known in ~eneral consist or a
machinP mounted on a ch2si~ which ha~ a roller ~Ystem ln
order to move the ~achine mounted thereon alons the welr
by means o~ rails or ~uides fixed on the gro~nd. ~hi~ tyP~.
o~ machines lncorPorate a spoon with an openinS sYstem by
m~ans of cable which moves Along the ~rating being open
wh~n golng down and closed when g~in~ up.
Also the ~oresaid machin~s usuall~ have a crdne
iib or crane arm Provided with hinges fixed on a ~ eable
~ase havlng ~t their traPpin~ en~ a p3ir o~ clamps cap~blP
o~ trapping voluminous ~odies and large si2e trunk~ which
the spoon o~ the shovel cannnot take out o~ the water
s~face; said machinss are h~ndled b~ an oPer3tor which
ha~ to ~e r~ad~ at all times t~ maintain the apPropriate
clcanno~ hv ~at~r which, as mentlon~d be~ore, is used
to mo~e tha ~urbines o~ electric power statlons.

1 invention is that the stru~ture o~ the m~chine avoids the
need ro~ forming an oblig~tor-~ pas3-waY towards the
~r3nsporter at the mo~ent that the 3poon i, taking the
dirt o~t, whi ch dirt mRY be composed ~r small Parts ~s
well a~ larqP h~iQs and tru~ 1' consl~er~ble
dimen3ions. -~.
~ nother economi~ advantage of this invention i5
that a ccmplement~r-~ crane arm which other cleaning
3 systems for srating~ have to in,tal 1 in order ~o be able
to take out the already mentioned lar~P bcdies an~
c~n~iderabLe.si~ trunks, is ~liminat~d.
,:
Another advantage in relation ~o thi~ in~ention
is that the control ~r mechanisms bY means o~ a hydraulic
cQn~er may ha carried out either manuallY or aut~maticallY
~o that the operator o~ the sYstem ma~ comblne the tasks
o~ cleaning with other ~uties,
~,
~ ~ Another advantage o~ the Proposed machine for
~léaning gratings consi~ts o~ its c~p~bility o~ cl~aning
dny tyPe o~ w2ir and of an~ dPPth ,ince it~ o~cillatorY
