FOHB .A.SSEI{RLING OR OI'ERJ:\TilJG THE DREDGE

B. GENERAL DESCTII PTI O'tJ AND OP:E:::~·,_ TI OY!

The nEllicott Drap:on" is essentially a portable hu].l and house which supports and shelters. a pm.-rer dl"i­ven pump and other machinery and equipment necessary .for diccinc and conveyeing materi~ throurh a pipe line from one location to a selecte~ point of discharge.

A rotary cutter is mounted at the head of a steel frBJ:tle, the ladder, hinged near the forv1ard end o.f the dredce. The cutter loosens the Baterial, which, in a state o.f suspension, passes throuch a suction pipe int-, the pump. It is disc;harr;ed into a pi~e leadinc to a point called the nfi~l". Discharce pipe is s:ometimes ' referred to as ''spoil" pipe, a1 so pontoon eli scharge pipe if carried on pontoons, or shore pipe if supported ashore

11he position of the dredf~e is maintained b-:,~ one of two steel tubular sections called spucts located at the stern of the hull. One spud is lowered to tho bot­tom and is used as a pivot to swin8 the ladder through an arc or "cut".

S.winging the dredge is con trolled by pulling against anchors beyond each side of the dredp,c attached

.• • • • • to

to drw:1s on the haulinr: and hoisting machiner·y by means

of' cables. These cables are called "s1-d.nr, lines."

C. GEJETIAL DESC~nPTIO~J A;.fD :, ... ,IETJ) EHLC'I'ION

The "ELLICOT'r DnAC·ON" is deaic;ned so that the

entire unit may be conveniently shipped, erected at the

site o:f operation, later dismantled and moved again for

re-assemb1.y.

IJ.1he "F.LLICOTT D!l.'~Co:,T"· has been com'1letely assem­

bled in our shop and dismatlnd f'or shipment "t--ri th neces-/

sary ~arts marked to aid erection in the field.

The hull is composed of a center tank supporting

thtS pumpine unit and thH haulinr-: an.d hoisting machinery

plus four outboard or ballast tanks.

Features have been incorporated in these Aec­

tions that make; it possible t.o bolt them toGether, while

afloat, to form a single unit. 'rhe povmrod dredging

pump, piping and spud. cuble load sheaves remain mounted

in the cotitor section at nll times.

A seconilapy drive un:\. t, r.10unterl on a structural

:frmne is located on the deck at the for1-rard ond of' the

cutter tank. This unit drives tho cutter and the hauling

and hoistint; m'achinery b:,r me?-ns of chain drives.

I-Iingod at tho 1 JrwHrd end of the cent or tanlc and

hung by cables fror1 an "A" fruroe is u structural member

called the ladder, "'..rhich supports a pO't·'erod rotary cut­

ter, housing the inlet to the suction pipe.

Located at the .forv.rard end of the dredge are two

snagr.ing booms supported by cc.bles hung :from the r,allows

f'rame. rach boom is controlle. d b:r tv.ro individual hand­

winches : one topping "t-rhich is mounted on tho side mnm­

ber of the gallows frarno and one which ls mounted on

the deck near the gallows frame to control the lines to·

the lifting hook.

called spuds, hung by cables from n vnrtica1 steel spud

frame. 'l'he so spuds are raised and lot-.rcrcd h;r means .of

calbes lending to. tho hauling and hoisting machinery.

L steel enclosure with doors and windov.Ts forms

a deck hous0 .for prottictinz the machinery and the oper­

ator against wenther conditions. Vlherens this steol

deck house is gelvanized, the surface has been prepared

for painting in tho field. No further neu~rnlizinc

agents nru noccss8.ry prior to paintinp;, if painting is

desired•

Hhilc it is o.ssumed that tho erection of' this

drod.~o will bo accomplished with non-profns siont:.l supEr

vision and with semi-skilled lo.bor, it is ndvantf::..e;eous

to hnvo at lonst one of tho personnel f~milinr with

steel erection, machinery instnllation nnd mechnnicul

operation.

Excludinc assembly of the fleeting discharge

pipe linE-~ beyonel tho dredge Etnd the preparn tions for

opere~ tions , exporif'ncc has indicated thnt .about 350 ·,·., man hours are required to erect this dredge• This

figure is po.sed upon the follot-ling conditions : three

or !'our men v.Torking (one v.ri th some experience in hand­

ling mater~al and mechanical erection)~ c~anc service

to handle nll units, materials unlpndcd nt Aroction ~

site, and good advance prepnrntion.

D. THE ERECTION SITE

A site of erection should be selected with the

f'ollowing objectives in mind :

1. Vihilo th~'J dr£1ft of the cor.1';loted drod[~:c is

approxim['.tcly 33", it is recommended t:hc.t a.

depth of'. ,4 feet be provided for manoeu-vering

purposes.

2. Erection materials, sppplios and fuel must be

transported to the wnter 1 s Rdge.

• • • • • 3. The

- 7 -

3. The r-;round nea:r ~he. vater must. be soltd enough

to support the crane :ror lif'tin~ the cebter. section. See page N~ 7 for Height of' center

section.

4. A minimum length of discharee pipe must be con­nected to the d~edge. (See chart Section II, pare· ••• )

E •. TOOLS AND EQUIPi'·1E}:iJT NEFDED FOE ERECTION

It is advisable to have crane service available to unload and place the VB:' ious units. See page N~ 7 :for

weiehts o:r units.

This necessary erection equipment is not furnished by Ellicott i"'achine Cor"!;'oration.

1 • THo ( 2} 1. - 1 /8" di ametre v.r~re rope slings, ·50 :reet long.

2.-TlvO .(2) ~"diameter-Hire rope slings, 1.5 :feet

long.

3. Ten (10) lt.rood timbers 4" x 11n x 4 :feet.

F. THE USE OF BALLAST

Stnce the dredge is generally assembled in the waters, there arc times when Heights and centers o:r gra­vity are not :favorably distributed. To of'fset these con­ditions, balla.st tanks have oeen built into the side sec­tions or the hull. A gasoline engine driven bilge and ballast pump has been provided to :fill and empty the ballast ta1ks when necessary. The Uf!e or h·.•ter ballast is detailed in as somlJly dra"t-·inr; proce~.ures.

G. CAUTIOUS DURIIIG ERECTitTU

1. Study thG assembly instructions before starting erection.

2. Don't al.tf'lr any construction in orcler to as­

semble amy part or unit. If' installed correctly

••• all

8

all ryarts wjll fit it match • . .

3. Pe cortain that the NO. tr:r is deep enough to float

the completed dredc;e.

~-· Check the h.ull sections .for leal-cs duo to damage

in shippinr..

5. The side sections of the hull, because of their

square -sectional shnpe, will not float upri~ht

in the Hater without ballast.

6. Use grommets 1.-vith all bolts usen in botinc the

hull together.

7. Add water ballast to tho aft trimtanks before

atte!11pting to install the ladder.

8. Study the operating instructions before start­

ing or oporatin~ any machinery of the dred~e.

sequence of erection rocor1m.ended. 'l'his sequence and its

orocedure have been established by years of experience

in th0 field, and these ~ecomraendations should be fol­

lowed as closely as. possible.

P.ART II

A.

OPERATION.

PRINCIPLES OF OPERATION . •

The "ELLICOTT DRAGON" is o. pol-rered pump un.i t designed to pump materia such as mud nnd snnd from the

bottom of a river, lake, or other body o~ water and propel

it through o. pipe line as a mixture of solids an.d t-rnter to

o. disposal area at some distance .from thG dreoc;c. There

nre se..veral conditions that have to be "created" by the

dredge operator.

The dredge operator hns to seek out the mate­

rial. This is done by raisin~ or lowerinG the end of the

suction pipe vertically and also by swineinG it horizon­

tally through the motion of the dredGe moving in an arc

across the cut.

The dredge material has to be properly suspen­

ded. in water in order to be Mvr;d succesf'ully. The cutter

agi ta.tes the roo. tcrinl, and tf:e speed with ~.rhich the cutter

rotates and the speed with which the end of tho suction

. pipe (that is encased in the cutter) fa st-mng into. contact

with this mnterial controls the proper suspension of mate­

rial in water.

The material must be carried away from the

dredge wit~ suff'icient velocity to keep the material in

proper suspension. This condition is directly controlled

by the length of di schnrr;f) pipe o.nd the hfdght above the

wnter level on which the dred~e f'lonts tho.t the material

is dischnrged.

B. FUNCTI OH 0.8' ~ID-~ B\ R TS

The follotrlng purngrnphs describe the func­

tion~ of tho machinery items on tho dredge and the uso of

the pipe line. l:hile rending these instructions, it j_s

1 • Dredgi!lf Ladder end Cutter Assembly :

Tho ~ i tating :machinery on th~ drodge consists

of a s true tural steel d.rcrl.ging 1 addE-r housing

the suction pipe, cutter, Dnd cutter shQfting.

The ladder is supported at tho art end by trun-·

nion bearincs mounted nt the foM·TL'.rCI end or the

hull, and at the outboard. end by t-.rire rope nnd

blocks .from tho "A" f'rn.m.e. The ap:itnting cut­

ter is driven throue-;h chain drives pol-r,erod from

the auxilillr y dri vc unit Diesel engine. On the

forward end of the ladder on ei thor s.ide of' the

frame arc mounted tv.ro "swing shcr.vcs". Viro

ropes !'rom the hauling and hoisting machinery •

pass throup~ each o.f the two sheaves to nnchors

locD.ted at <-'ither side of the chr.nnel being

dredP,od. Leading from the suction hond on the

f'orward end of' the ladder to the main drode;ing .. pump is the suct.ion pipe, uscd·to carry the

mixture of' solids and 'Hater to the dredgiDtr;

pump located. in the centcr_tnnk. A .flexible hoBe

is installed in this pipe near the .forwa~d end

of' the hull to nllov.r tho ladder to be raised or

lowered nbout ito trunnions.

2. Dredging pum~ :

The dredging pump, l-rhich is driven by tho main

Diesel engine, consist or a rotating im~eller,

enclosed in a pump case, v.rhich sucks the Nater

£E_ the spud ( v.rhen lifting) b8:JO~.d tho selec­

ted point for lif'ti~g. Holes are prbvidod in

the spuds for this pin.

Q~ .E!=i.ch spud has a trnvel limit of about 11.,_ foot

gets deeper than this limit of' travel, the.

limiting pin must move to the-next hfc:hor

(1) Haisf) the s·pud until one hole ~..!:! tho

(2) Inser~ lockinr: pin in this hole (A stool

pin is ~rovided for this pnrposc) and

b. Locating the stv-ing anchors is very import­ant. The anchors should be placed approxi­raately 90 degrees to the cent·er line of' .;J:!

the ladcier \<lrhen the ladder is in the mid­dle of' a swing. This uill. keep the cable f'rom t'oulinc; the cutter-when the ladder is at the ends of the Sl-Ting.

H&'qNING : PIA CING THE ANCHOR IS A HAZARD-. .

· OUS OPERATION AND !fUST BE D·ONE CORRECTLY

TO PR~~VRUT D~JUSRY TO PERSONNEL.

c. The most expedient method of placing the anchor is to suspend .it from the anchor barge or -boom Nhere it can be I'eleased or cut loose by one man 1Jen the anchor is over the desired location. All personnel mu.st 'be well clear of the anchor and lines attached to the anchor W1 en it is released or cut loos~. The rnan releastn~ ~he anchor muat take precautionary measures to assure that he is in a position clear of' .falling anchor. and lines attached to the anchor .•

' d. Prior to the placement of the-nnohor,·abuoy

should.be attached to the anohor shac~le by a chain or cable or surf~cient leucth to permit th? buoy to .float 'on the sm-i'ace as a mar~er. Later, the buoy chain o~ cable is used to raise the anchor tor pl~cing it in a new location. ,

13. Control Equipment

One vacuum p,auge and two tho pressure gauges

are :mounted on a ~auge bOard convenient to

the dredge operator's lin~ of vision. The

vacuum gauge measur0s 1 in inches or. mercury,

the suction head of the drE>dge pump. Tho

main nill~~ discharge pressure g~uge mcnsures

in pounds ner square inch, the ,discharge

pressure in the discharge lihe. The pressure

gauge on the rm 1-ratr~r urcssure line i"ndi­

cates the_prP.ssuro, in pounds per square

inch, on th0 main pump service pater gland.

It is good practice to attach one ru'b.iber

sleeve to each seJtion of pontoon liri~.

Thus l·.rhon adding 3ections to existing

l. Checkiup; L-adder Position with Relation to S1-dnr; Anchors

With the dredge located .'3t the >vork site, tho next step

is to check the position of the drecle:ing lc.1dder with re­

lc:tiol:l to the swing anchors or deadm~.:.:n. S"Win[~ the dredge

to the starboard and port, as shown on skc7tch on opposi­

te p!3zc, obst"3rvinc that tho angleo bet\'reen the cutter and

thcswing cnble should not be too snf.lll, allowin[; the cn.­

ble .;;:>be cut by, or rolled up on, the cutter while

dredging. For future reference, note the angle bot\oreen

the buoys or stakes rnrkinc the sides of tho cuts and

a point on the rtAn frm'le of the dredge. This nliOllllunt

will chance as the dredce r~dvances t::nd nust be rechecked.

vlith the dredge in position, the pipo line and

svling cables connected, nnd machinery runninr,, drcdce

operations can be str.1rted.

Assuno for instructional purposes thnt tho depth

of the watar ahead of tho dredge is 6 feet, and. that

the cut to be mdo is 18 feet in depth. The cutter, there

fore, can be lowered only a few feet into the Elf.ltE:rial

on the first advc:mcc of tho dredge.

that the first cut is about one half the depth of the

In shallower_ mflt,;rial1 the first cut nay be even less,

After ndwmcing the dredce, the second cut rr.D.y be as

much as two cutter dianeters in depth, And the third

advance will allow r: [;reater depth, etc., until the

18 foor depth is reached by the cutter. Diggine clear­

ance for the ladder r1r'ly require quite A few hours of

operation, but it is absolutely necessary to start pro­

per drodcring operations.

At first it will probably be necessary to r.1ako severa

moves of the dredeo before tho desired digeing depth

is rof.lched. 'rhis is duo to tbe fact thCJt the ladder

will drag on the shoulder loft by the first cut.

It is desira.ble that the cut be level on the bot­

tom with no high epots or depression ns soon as possi­

3. Rules for the u~e of Hauling and Eoisting Hachnory

Before swinging the dredge en its first cut, these rul es for usc of t•c hauling and hoisting machinery should

be cons~idered :

a. To insure lone: wear ond rnininun operational diffi -culties, the cables should be evonly spooled on the

drums with no avcrlapping turns. To insure this_, a

slight str·ain should be kept oneach of cnbles as

they are spooled off the drums by applying the

brakes.

b. \'llien coning to the end of tho swing, and before

liltopping the ;wing of dredee by relea.sinr:: the clutch,

the cable should be kept from spoolint; free by mo­

mentarily applying the brake.

c. lfuen engaging the clutch -vrith the~ le1yhaft turninc;, the brake should be released at the sa.me tiue.

This should a smooth simultaneous operation.

d. l"rorn. the bow of the droclge the cutter, in appearance,

rotates counterclockwise. The digc:ine cut is there -fore, fron port to starboar ae::ainst turn of

the cutter. However, in most cases the ladder can belovcrGd and the cutter will a,citate natcrial on

the s1-dnc_: fron starboar to port. If the rwteri.sl is

compn ct, tho rotf.!.tion of the cutter vrill tend to

r1ovetho dredce frqn st:Jrbon.r to port faster than

the port swing ct:.blc drun cDn can spool in the cable.

To prevent a slack port cllble and excessive swine­

ing speed , the brake on thd starbollr s>-rinc drun

should be applied gently to retardnovencnt of

the dredge.

A. IlJTRODUCTION :

It is false econo!.1y to operate r:o.achinory with badly

worn parts. Ho nachinery will operate very long without prop

per lubriMtion or adjustments .to conpensatq for wear. The

effectiveness of the "ELLICOTT DFU'-\GOH11 will t.~epE;;nc'. largely

upon the attention given the Machinery and equipnent aboard,

B. FUEL OIL : The "ELLICOTT DRJ-;,GuN" has. a 750 gallon fuel tank

built into the hull center s.:;;ction. Supply and return lines

furnish fuel to the (".rec1.c;e punp Diesel erl£ine anc, hDuling

and hoisting r.18 chinery Diesel engine dire.ctly fron this tnnk.

The fuel oil for these Diesels should be in accorc:an­

ce with the quality designated in tho Operatiors' U:muals

for these eneines.

C. THE LADDER

Except the water lubrication cutter heac1. bushing CJ.t

the ladder head, all beflrings on the la\!c~er have fittirlf,S

for grease lubrication ; see luhric~tion cliagran •

M9.in shaft and gear trnin shaft bearings are provide

with shins for renow1l as needed to take up wef.lr,

The cast iron cutter head bushinr is removed by supporting

the ladder encl on a bar:~e J first, renovine the cutter ; se­

cond, the forward portion of cuttur shaft; third, the four

bushinG collar nuts; fourth, backinc the bushing out of

the cutter heac! housing.
