MOUNTING BOLTS INFORMATIONThe mounting bolts are manufactured from heattreated steel of high quality. They MUST NOT be bentor heated. The threads have been rolled and must notbe lengthened by means of cutting. Doing so willweaken the bolt. Nuts must never be secured bymeans of tack welding.

The mounting fittings are bolted onto the chassisframe via driven bolt connections. Special mountingbolts, on which the smooth part of the shaft is able toreach almost through the mounting fitting and thechassis, must be used. Drilling diameter is 13.8mm.Place a hard washer (HB 200) under the head of thebolt and the nut.

MOUNTING FITTINGS-TYPE AUse 20mm mounting bolts, bracketed to the framewith M14 bolts, 4 places. See Fig. 5.

MOUNTING FITTINGS-TYPE BA combination of types C and D. The single bolt fittingis fastened using M14 bolts, 6 places. The twin boltfitting has a cross bar under the chassis. The singlebolt fitting is not raised above the frame as mentionedbelow, but the crane must rest on the frame.

MOUNTING FITTINGS-TYPE CSee Fig. 6 and 7. Use 7/8" or 30mm mounting bolts,fastened using M14 bolts, 6 places. The mountingfitting is raised until there is a distance ofapproximately 0.2" (5mm) between the loader and theframe. See Fig. 7.

MOUNTING FITTINGS-TYPE DSee Fig. 8. Use 7/8" or 30mm mounting bolts, 2places, and a cross bar under the chassis.

The height of the spacer inside the side member ofthe chassis must be carefully adjusted to fit betweenthe flanges, and the four corners rounded 0.2"R (R5).You must prevent the spacer from turning by lockingit to the subframe using a piece of flat iron. The flatiron must not be welded onto the chassis. The edgesof the cross bar towards the chassis are rounded 0.2"(R5) to prevent wear and tear on the chassis.Fastening must take place in stages in order for thecross bars to press evenly against the lower side ofthe side member.

INSTALL-MHS/LG: 99901230: PARTS-10CHASSIS REINFORCEMENTIn most cases it is necessary to reinforce the chassisso that it can sustain the strain applied by the crane.

The strain from the crane represents a bendingmoment on the chassis approximately correspondingto the load moment of the crane, plus 15%. Thus, anecessary reinforcement is calculated on that basis.The dimensions of the chassis frame being taken intoconsideration.

It is a general rule for all subframes that if the craneis fastened against the frame, you must place a wearplate as shown in Fig. 13. If the crane is raised until itis free of the frame, as shown in Fig. 7, the wear plateis not needed.

To maintain the flexibility of the chassis, thesubframe should be fastened to one end only, otherfastenings must be flexible. Where great demands aremade to the strength, the subframe and the chassiscould be bolted together with fixed strap-plates in thetotal length of the frame.

The subframe for crane, body hoist, tipping gear, andfor coupling for semi-trailer, etc., must always be inone piece, and preferably with the same cross-section in the whole length.

If the cross-sections of the subframe are different,the crossing must be smooth, see Fig. 12, and thewelding must be done very carefully, and all the waythrough.

INSTALL-MHS/LG: 99901230: PARTS-12INSTALLATION WITHOUT CHASSISREINFORCEMENTIf no reinforcement of the chassis is necessary, thecrane may be mounted as shown in Fig. 13, 14 and15.

Fig. 13.The crane must never rest directly on the chassisframe, but should be placed on a wear plate of .39"(10mm) flat iron. The length (L) should be 7.87"(200mm) longer than the distance between thecrane's mounting bolts. The width (B) equals the widthof the side member less .59" (15mm). When welding,avoid damage to the edges of the side member.

This mounting method is only recommended for smallcranes, and you must be sure that welding on thechassis frame is accepted by the authorities and thetruck manufacturer.

19990707Fig. 14.If welding is not allowed, wear plate can be made asshown. The length (L) equals the distance betweenthe mounting bolts, plus 7.87" (200mm). For cranesup to 7 ton-meters, an .31" (8mm) plate is used. Forlarger cranes the plate should be .39" (10mm) thick. Itis often necessary to make cutouts in the plate toaccomodate bolts, struts, etc., on the chassis.

Fig. 15.If the crane has to be raised above the chassisbecause of gear box, etc., the crane is mounted on ashort subframe as shown in Fig. 15. For cranes up to10 ton-meters, a box section of .31" (8mm) thickmaterial is used. For cranes of 10 ton-meters or more,the thickness of material must be .39" (10mm). Thesections are tapered 30° at both ends, and two U-sections - a bit lower than the box section and of .24"(6mm) thick material - are welded between them. Thelower edges of the subframe should be rounded .2"R(R5) to prevent wear and tear on the chassis.

INSTALL-MHS/LG: 99901230: PARTS-1319990707INSTALLATION BEHIND CABThe drawing below shows mounting of subframefastened to the chassis by means of strap-plates infront and flexible fastenings at the rear. The subframeis made of U-sections, and between these, traverseU-sectons, which are placed a bit lower and have athickness of material of .24" (6mm), are welded. A U-section is placed as close as possible to eachmounting bolt. From the crane and to the rear, the U-sections are placed at a distance of 78.7" (2m)maximum. From the rear mounting bolt and to therear, the subframe is fastened by means of a strap-plate (see Fig. 16) at a distance of approximately31.5" (0.8m), and then by means of a flexiblefastening (see Fig. 17) at a distance of 47.24" (1.2m)maximum to the rear, as shown on the drawing. If thedistance from the front mounting bolt to the front edgeof the subframe is maore than 7.87" (200mm), youshould mount a strap-plate.

INSTALL-MHS/LG: 99901230: PARTS-14FRONT MOUNTED CRANE PLUSTIPPING GEARThe subframe of the tipping gear must be safelyfastened to the chassis around the rear bearing.

Therefore, the subframe must be fastened from therear to the spring suspension of the rear axle bymeans of strap-plates (See Fig. 16) and further on bymeans of flexible fastenings.

The mounting fittings of the crane must not be weldedonto the subframe. If large demands are made of thereinforcement of the chassis, and the truck is mainlyused on even ground, strap-plates can be used alongthe entire length, and mounting fittings can be weldedonto the subframe.

19990707

INSTALL-MHS/LG: 99901230: PARTS-15REAR MOUNTED CRANEThe subframe should be made of box sections toensure maximum stability when driving, and shouldbe made as described in the previous paragraph.Traverse U-sections are welded between the boxsections at a mutual distance of 78.74" (2m)maximum, though there must be a U-section by eachmounting bolt. If the loader is rear mounted thestabilizer legs must face backwards. To the frontspring suspension of the rear axle the subframe mustbe fastened to the frame by means of fixed strap-plates. In front of this section flexible fasteningsshould be used.

INSTALL-MHS/LG: 99901230: PARTS-17STABILITY CALCULATIONWhen a crane is mounted on a truck, it is necessaryto check the stability against overturning.

Note that the rules concerning installation of truckmounted cranes may vary from one country toanother, and that this installation manual should beregarded as a guide only. You should check the localrules and take those into consideration. The truckmanufacturers often have special instructions formounting of extra equipment which must be compliedwith, if the guarantee is to apply.

CRANE MOUNTED BEHIND CABFig. 1 shows a truck with crane on which the outriggerlegs are extended. The supporting area is now formedby the letters Q-R-S-T-U-V. If the load (PL) is swungoutside this area, the truck will be in danger of tilting.

Normally, this risk will be greatest when the boom isin the shown position, at a right angle to line m

The stabilizing moment (MS)can be determined as follows if the center of gravity(G2) of the crane lies within the tilting line m:

MS = (PF x LF) + (PR x LR) + )G1 x LC) + (G2 (LC - H2))

If G2 lies outside the tilting line the last term of theabove equation is negative.

The tilting moment (MT) is determined as follows:

(MT) = PL x a

The safety factor against overturning must be:

If the chassis is short, the stability must be checkedwith the boom pointing straight forward. The procedureis the same as described above, and the tilting linewill equal the placing of the front axle PF

Often, it will be impossible to obtain sufficientstability in this boom position. Consequently, the bestsolution would be to reduce the crane's slewing angleto 200° covering the truck body.

The stabilizing moment (MS)is determined as follows when G lies within tilting linem:

MS = (PR x LB) + (G1 x LC) + (G2 x (LC - H2))

The dimensions H2 - G2 - G1 - f are shown in TechnicalInformation 313501 and 317902.

The dimensions PL - L - S are shown in the brochure.

SUPPLEMENT TO STABILITYCALCULATIONSThe increasing demands from the authoritiesregarding stabilty and the tendency to mountproportionally larger cranes on vehicles of standardgross weight mean that it is necessary to check thetheoretical stability before mounting the crane.

A number of countries now require a theoreticalsafety factor in accordance with DIN 15019 and FEM5.007:

Front mounted crane S = 1.25Rear mounted crane S = 1.40

MS Stability momentS = ___ = ________________ MV Tilting moment

In such cases, the stability test is required to becarried out with a stability load of 1.25 x PL + 0.1 xG2, which applies to both front and rear mountedcranes. (G2 is the weight of the boom).

If the stability requirement cannot be complied withby means of the crane's outrigger legs, it may benecessary to mount an extra outrigger beam. See Fig.3 and 4.

The tilting moment:

MT = PL x a

PF and PR, the weight of the truck must be inclusiveof platform and permanent equipment.

19990707If four outrigger legs are used, it is necessary tomake the chassis torsion resistant in order for theextra outrigger legs to transfer the moment. This isdone by making a subframe of RHS (RectagularHollow Section) tubes supported by a transversebracing of corresponding profiles.

This is against the truck manufacturer's generalrequirement for flexible chassis, and therefore, wehave to refer to the recommendations of the truckmanufacturer.

INSTALL-MHS/LG: 99901230: PARTS-22PUMP & HYDRAULIC SYSTEMIt is important that the correct pump be chosen, andthat it is installed properly, in order for the crane towork to full satisfaction.

If the pump chosen is too small, the crane willoperate slowly. If the pump is too large, the workingspeed, and thus the shock factor on the crane is toohigh, and the life expectancy of the unit will bereduced. Furthermore, the generation of heat isincreased, and in some cases it may be difficult toget enough torque from the carrier vehicle's engine.

PUMP SELECTION CHECKLISTDetermine the requirements of the pumpperformance. The performance stated in theInstruction Manual is effective performance atworking pressure of the crane.

Choose number of engine revolutions.

Choose gear ratio of PTO.

Choose the pump size according to the followingtable.

If a suitable pump size is not found, choose the onenearest your requirements, and change the number ofengine revolutions accordingly.

Check that the engine can perform the necessarytorque.

Check that the PTO and the drive shaft can transferthe necessary torque.

Check that the regulator of the fuel pump operates atthe chosen number of revolutions

INSTALL-MHS/LG: 99901230: PARTS-24PUMP MOUNTINGDirect mounting of the pump on the PTO is thesimplest and most reliable solution.

If the pump is mounted with drive shaft, the universaljoint yokes must be parallel, as shown.

By mounting of drive shaft the two angles B1 and B2must be the same. The axle of the PTO and the axleof the pump must be parallel.

This also means that if the engine tilts backward inthe chassis, the pump must be mounted with thesame slope.

Before starting, the pump housing must be filled withhydraulic oil.

By mounting of double pumps on divider gearbox, thegear ratio must be taken into consideration, as itchanges the speed of the pump and applies morestress to the drive shaft. Before mounting of pump,remove the seal of the drive shaft and plug the leak-oil hole. Fill the gear housing with oil. Refer to thepump manufacturer's instructions.

INSTALL-MHS/LG: 99901230: PARTS-25NORMALLY MOUNTED CRANEPipe and hose connections must be made as shortas possible, and be placed with as few bends aspossible. Angular connections must be avoided onthe pressure pipe and banjo connections must not beused. The suction line must fall down towards thepump without upward bends, which may create airpockets. The suction hose must be mountedcarefully, in order to avoid air being sucked into thepump.

REAR MOUNTED CRANEA separate tank with a capacity of approximately 1.5to 2 times the pump performance must be mountedclose to the pump. The base of the crane cannot beused, as the suction line will become too long andcreate cavitation in the pump. The pressure pipe andreturn pipe should be one dimension larger thanindicated in the table.

NOTETHE BASE OF THE CRANE MUST ALWAYS BEFILLED WITH HYDRAULIC OIL TO ENSURELUBRICATION AND TO AVOID CORROSION OF THEROTATION SYSTEM.

REAR MOUNTED DETACHABLE CRANEThe rear mounted detachable crane is connectedusing quick-release couplings turned opposite eachother to prevent incorrect connection.A safety valve (part no. 60 357) is mounted betweenthe pump and return pipe, close to the pump, toprotect the pump in the event that the quick-releasecoupling is not connected. Opening pressure shouldbe 435 psi (30 bar) higher than the working pressureof the crane.

A blow-off valve of 725 psi (50 bar) (part no. 12 43614) is mounted in the return line of the cranebetween the valve block and the quick-releasecoupling to protect the system in the event the returnquick-release coupling is not connected.

CRANE MOUNTED 2-CIRCUIT HYDRAULICSYSTEM (TYPE TS)Due to the larger volume of circulating oil, the crane'sstandard oil tank and return filter will not be adequate,therefore a separate oil tank should be mounted. Thecapacity of the oil tank should be approximately 1.5times larger than pump performance. See chartbelow.

A linking of standard tank and separate tank is notrecommended. Remember to fill the tank in the base.
