Keep this mnul, nd ll lels ttched to the crne, redle nd with the equipment t ll times. Contct Thern, Inc. for replcements. Check luriction efore use. Instll the wire rope securely to the winch drum. Keep t lest 4 wrps of wire rope wound on the drum t ll times, to serve s nchor wrps. With less thn 4 wrps on the drum the wire rope could come loose, cusing the lod to escpe. Keep hnds wy from sheves, gers, wire rope, nd other moving prts of the equipment. Disconnect the power efore servicing the equipment. Keep ll unnecessry personnel wy from the crne while in opertion. Keep out of the pth of the lod, nd out of the pth of roken wire rope tht might snp ck nd cuse injury.

4 pge 4 Owner's Mnul for Thern 5122 Series Portle Dvit Crnes Suggestions for Sfe Opertion (Cont) DO NOT do the following: Do not lift people, or things over people. Do not wlk or work under lod or in the line of force of ny lod. Do not exceed the lod rting of the crne or ny other component in the system. Do not use more thn one crne to move lod tht exceeds the lod rting of single crne. A shift in lod weight could overlod the equipment. Do not use dmged or mlfunctioning equipment. To do so could result in filure of the equipment. Do not modify the equipment in ny wy. To do so could cuse equipment filure. Do not wrp the wire rope round the lod. This dmges the wire rope nd could cuse the lod to escpe. Use sling or other pproved lifting device. Do not operte the crne with gurds removed or improperly instlled. Do not divert your ttention from the opertion. Sty lert to the possiility of ccidents, nd try to prevent them from hppening. Do not jerk or swing the lod. Avoid shock lods y strting nd stopping the lod smoothly. Shock lods overlod the equipment nd my cuse dmge. Do not remove the winch or other components from the crne, nd do not use these components for ny use other thn for their originl intended function. Do not use the crne to drg or pull lods. This will crete side pulls which could dmge the equipment or cuse the lod to tip. Do not leve suspended lod unttended. Plce the lod on the ground if it must e left unttended. Do not djust the winch rke with the lod suspended. Do not operte or pply lods without ll pins securely in plce. Do not djust oom ngle while the crne is loded.

5 Owner's Mnul for Thern 5122 Series Portle Dvit Crnes pge Instlling the Crne Importnt! A qulified professionl should inspect or design the foundtion to insure tht it will provide dequte support. Locte the crne so it will e visile during the entire opertion. Do not instll the crne in n re defined s hzrdous y the Ntionl Electric Code, unless instlltion in such n re hs een thoroughly pproved. Do not instll the crne ner corrosive chemicls, flmmle mterils, explosives, or other elements tht my dmge the crne or injure the opertor. Adequtely protect the crne nd the opertor from such elements. Position the crne so the opertor cn stnd cler of the lod, nd out of the pth of roken wire rope tht could snp ck nd cuse injury. Attch the crne to rigid nd level foundtion tht will support the crne nd its lod under ll lod conditions, including shock loding CONSULT APPLICABLE CODES AND REGULATIONS for specific rules on instlling the equipment LOCATE THE CRANE in n re cler of trffic nd ostcles tht could interfere with opertion. Mke sure the crne is ccessile for mintennce nd opertion INSTALL THE CRANE on level surfce. An unlevel surfce my cuse the oom to rotte in the direction the mst is lening FASTEN THE BASE securely to the foundtion to withstnd pplicle overturning moments nd mounting olt rection. See Tle 1.

It is your responsiility to detect nd ccount for different fctors ffecting the condition nd performnce of the equipment THE INTENDED USE of this mchinery is to lift nd lower lods of its rted cpcity or less. It is not for lifting people or things over people THE PULL REQUIRED to move the lod must not exceed the lod rting of the crne. Consider the totl force required to move the lod, not the weight of the lod THIS EQUIPMENT CAN develop forces tht will exceed the lod rting. It is the responsiility of the equipment user to limit the size of the lod. Inspect the equipment regulrly for dmge ccording to the instructions contined in this mnul PERFORMANCE RATINGS of the equipment re ffected y the position of the oom, nd the mount of wire rope you use. See the Performnce Chrcteristics Tles on pge 19. c LOAD RATING represents the mximum pull tht cn e plced on new equipment. Lod rtings re ssigned vlues for specific oom positions nd wire rope lengths. LIFT vries with the position of the oom nd the length of the wire rope. REACH vries with the position of the oom DUTY RATINGS refer to the type of use the equipment is suject to. Consider the following when determining duty rting. c d ENVIRONMENT: hrsh environments include hot, cold, dirty, wet, corrosive, or explosive surroundings. Protect the equipment from hrsh environments when possile. MAINTENANCE: poor mintennce, mening poor clening, luriction, or inspection, leds to poor opertion nd possile dmge of the equipment. Minimize poor mintennce y crefully following the instructions contined in this mnul. LOADING: severe loding includes shock loding nd moving lods tht exceed the lod rting of the equipment. Avoid shock lods, nd do not exceed the lod rting of the equipment. FREQUENCY OF OPERATION: frequent or lengthy opertions increse wer nd shorten the life spn of gers, erings, sheves, nd other components. Increse mintennce of the equipment if used in frequent opertions AIRBORNE NOISE EMISSIONS vry depending on lod nd the type of winch eing used. Stndrd configurtions do not typiclly exceed sound pressure level of 80dB(A) t worksttions VIBRATION LEVELS vry depending on lod nd type of winch eing used. Stndrd configurtions do not typiclly exceed virtion levels of 2.5 m/s 2. CONTACT THE FACTORY FOR MORE INFORMATION.

9 Owner's Mnul for Thern 5122 Series Portle Dvit Crnes pge Prepring for Opertion Importnt! When determining whether the lod will exceed the lod rting, consider the totl force required to move the lod CONSIDER THE OPERATION. Do not egin until you re sure you cn perform the entire opertion without hzrd INSPECT ALL COMPONENTS of the system. INSPECT THE CRANE nd other equipment ccording to the Instructions for Frequent Inspection. c d INSPECT THE WINCH ccording to the instructions in the Winch Owner s Mnul. OPERATORS must e in good helth, lert, thoroughly trined in operting the equipment, nd properly clothed (hrd ht, sfety shoes nd sfety glsses, no loose clothing). THE LOAD must e cler of other ojects nd free to move. Mke sure the lod will not tip, spin, roll wy, or in ny wy move uncontrollly KNOW YOUR LOAD nd mke sure you do not exceed the lod rting of the crne or ny other equipment in the system POSITION THE BOOM so the lod hook is centered over the lod. Avoid side pulls which could dmge the crne or cuse the lod to tip. See Figure ADJUST THE BOOM ANGLE y repositioning the clevis pin on the mst. Do not reposition the oom while the crne is under lod. See pge 19 to view different oom positions, A nd B. Figure 4 Positioning the Boom center line center line correct incorrect

10 pge 10 Owner's Mnul for Thern 5122 Series Portle Dvit Crnes 2.3 Attching the Lod Figure 5 Attching Lod ltch closed tight ginst hook Do not wrp the wire rope round the lod. This dmges the wire rope nd could cuse the lod to escpe. Use sling or other pproved lifting device CLEAR OBJECTS from the pth of the lod so you cn move it freely nd oserve it t ll times during the opertion MAKE SURE THE WIRE ROPE is not twisted. A twisted wire rope could cuse the lod to spin when it is rised off the ground. sling seted in sddle of hook ATTACH THE LOAD using nylon sling, or other pproved lifting device. Follow the recommendtions of the sling mnufcturer. SEAT THE SLING in the sddle of the hook with the hook ltch completely closed. See Figure 5. CENTER THE LOAD on the hook so it will remin lnced nd not tip or rotte to one side. 2.4 Moving the Lod Importnt! Oey stop signl from nyone. Mintin tension on the wire rope to keep it tightly nd evenly wound on the drum. If the crne nd lod re not visile during the entire opertion, get help from nother person. Appoint supervisor if more thn one person is involved in the opertion. This will reduce confusion nd increse sfety. When lifting lod, use tg line to keep the lod from swinging or twisting, while keeping yourself wy from the lod MOVE THE LOAD slowly nd smoothly, only smll distnce t first. Mke sure the lod is lnced nd securely ttched efore continuing OPERATE THE WINCH to rise or lower the lod. Refer to the instructions in the Winch Owner s Mnul OBSERVE THE WIRE ROPE s it winds onto the drum. If it ecomes loose, uneven, or overlpped, stop the opertion nd rewind the wire rope efore continuing. Continued opertion with overlpped or uneven wire rope cn dmge the wire rope nd shorten its life ROTATE THE BOOM to move the lod side-to-side. ROTATE THE BOOM slowly nd smoothly to void swinging the lod or cusing shock lods. Do not jm the oom ginst other ojects. PUSH AGAINST THE BOOM t the midpoint etween the mst nd the end of the oom. Do not push or pull the lod, wire rope, or ny other prt of the crne other thn the oom.

11 Owner's Mnul for Thern 5122 Series Portle Dvit Crnes pge Clening the Crne Importnt! Increse the frequency of mintennce procedures if the crne is: Operted for long periods. Used to lift hevy lods. Operted in wet, dirty, hot, or cold surroundings. Clen the crne to remove dirt nd help prevent rust nd corrosion CLEAN THE CRANE every six months or whenever it is dirty. c WIPE ALL EQUIPMENT to remove dirt nd grese. LEAVE A LIGHT FILM of oil on ll surfces to protect ginst rust nd corrosion. WIPE OFF excessive mounts of oil to void the ccumultion of dirt REMOVE UNNECESSARY OBJECTS from the re surrounding the crne. 3.2 Luricting the Crne Importnt! Mke sure luricnt hs temperture rting pproprite for the mient tempertures of the opertion. Luricte the crne properly to help protect it from wer nd rust. Red the following instructions crefully LUBRICATE THE ROLLER ASSEMBLY on the 522 se t lest every 3 months. Use grese rush to pply light film of NLGI #2 grese to the rollers nd cpscrew LUBRICATE THE WHEELS on the 514 se t lest every 3 months. Use grese rush to pply light film of NLGI #2 grese to the roller erings on the rer cster wheels. Apply 2 to 3 drops of 150 grde ger oil to the shfts on ll wheels. Rotte the wheels to llow oil to penetrte, nd wipe off excess oil to void ccumultion of dirt LUBRICATE ALL PINS t lest every 3 months.
