FeaturesHigh torquesLow speedsThe Viking motor is a high-torque low speed motor,which can be mounted directly on a winch drum orto a shaft without intermediate gears. This presentsmany practical benefits which appeal to the users ofthe equipment.Smooth, low speed performance from zero to ratedspeed without the need of reductiongears and nocompromise on output torque.Variable speed controlThe Viking can drive and brake in both directionswith variable speed by smoothly controlling the flowof oil in the circuit.SafetyFor cranes and hoists Viking motors and brakeassemblies are DNV approved. You don t need totake risks.Severe environmentsThe Viking motor is designed to be highly resistantto severe working conditions and environments. TheViking has proven itself on board ships, in underwaterapplications, in explosive and chemically corrosiveindustrial environments, in extreme heat and freezingcold.High efficiencyThe mechanical efficiency as well as the startingefficiency is 97%. Because of the extremely lowmoment of inertia the motor is virtually insensitive toshock loads, and protects the driven equipment.Viking is still the best tension control motor available.Quick selection diagram for Viking motorsThe diagram below represents the torque and speed, for winch applications.Oil viscosity in the motor case 40 cSt (187 SSU).TorquekNmTorquelbf·ft x 103Speed rpmFor continuous duty and/or operation in line screened area, please contact your Hägglunds Drivesrepresentative for final selection.3
Functional descriptionThe Viking motors are radial piston type with rotating case. The case is supported on the stationary cylinderblock (5) by two main bearings. An even number of radially positioned pistons (3) work in cylinder bores inthe cylinder block, which also houses the inlet andoutlet ports (A and C). Each piston is coupled by a1piston rod (2) to a cross head pin (6) upon whichfour cam rollers (7) are mounted. The two inner cam5rollers press against the cam ring (8) while the twoouter rollers work within their respective guide plates(1). The cam ring is anchored to the rotating case.The distributor (4) directs the input oil to the pistonsduring their work strokes andreturns the exhaustedoil back to the tank. The distributor is coupled to therotating case via a safety coupling (9). The motorcan be connected to a driven machine via twomounting surfaces on the rear end of the motor. The7symmetrical design of the motor has made it possibleto construct it as a 2-speed motor. This means that8two different speeds are obtained for a given flow.The simplest way of performing displacement change over is byconnecting a special valve, known as a 2-speed valve, direct to the connecting flange on the cylinder block.The motor is designed so that pressure pulsations in the motor case are avoided. This has the advantagethat impurities are not sucked into the case.Fig. 1 Viking motor1. Guide plate5. Cylinder block4. DistributorA Port A9. Safety couplingC Port C3. Piston2. Piston rod7.

AccessoriesBrake bracket, type BB-46 and BB-85Brake assembly, type BA-43, BA-63 and BA-85Each brake is available in three versions depending on their brake direction, clockwise, counter clockwiseand double acting. The Viking band brakes are fatigue resistant for the maximum motor torque in eachmotor series. The brake is intended to be used as a parking brake. For hanging loads in wet environmentswe recommend the use of a protective cover over the band brake. The brake linings are of non-asbestosmaterial and have DNV type approval.Fig. 25 Single acting double band,type BB 46 and BA 43/63Fig. 26 Single acting double band,type BB 85 and BA 85Fig. 27 Double acting, one band in either directiontype BB 46 and BA 43/63Fig. 28 Double acting, one band in either directiontype BB 85 and BA 85Braking torqueBraking torque in braking force direction, frictionfactor µ 0,35 after running-in period.Braking force directionTypeLoad LoadClockwiseCounter ClockwiseDouble acting13Single acting - double bandNmlbf·ftDouble 663006500047900BA-8519500014380012000088500

To avoid high temperature in the motor case the heat must be cooled away, becausehigh temperature gives lower viscosity and thatgives reduction in basic rating life.Fig. 37 Flushing connection D1 and D2on motor series 44 & 64- For continuous duty in applications with anambient temperature of 20 C (68 F), themotor case must be flushed when the outputpower exceeds the values shown below.Max power without flushingViking 44/64Viking 84120 kW140 kW(161 hp)(188 hp)19

Choice of hydraulic fluidThe Hägglunds Drives hydraulic motors are primarily designed to operate on conventional petroleum basedhydraulic oils. The hydraulic oil can be chosen in consultation with the oil supplier or your local sales office,bearing the following requirements in mind:GeneralThe oil shall have FZG (90) fail stage minimum 11 described in IP 334 (DIN 51354). The oil must alsocontain inhibitors to prevent oxidation, corrosion and foaming. The viscosity of mineral oil is highly dependentof the temperature. The final choice of oil must depend on the operating temperature that can be expectedor that has been established in the system and not in the hydraulic tank. High temperatures in the systemgreatly reduce the service life of oil and rubber seals, as well as resulting in low viscosity, which in turnprovides poor lubrication. Content of water shall be less than 0,1%. In Industrial applications with highdemands for service life, the content of water shall be less than 0,05%.Temperature limitsRecommended viscosityAt operating temperature: 40-150 cSt/187-720 SSU.Normal operating temperature should be lessthan 50 C (122 F)Viscosity limits 100 recommended 150* for operationwith large temperaturedifferenceViscosity indexMin. permitted in continuous dutyMin. permitted in intermittent dutyMax. permitted40 cSt/187 SSU20 cSt/98 SSU**10000 cSt/48000 SSU* Many hydraulic fluids with VI-improvers are subject to temperaryand permanent reductions of the viscosity.** Low viscosity gives reduced basic rating life for the motorsand reduction of max allowed power.Nitrile seals (std motor)Viton sealsSilicone seals-35 C to 70 C-20 C to 100 C-60 C to 70 CNitrile seals (std motor)Viton sealsSilicone seals-31 F to 158 F-4 F to 212 F-76 F to 158 FFire resistant fluidThe following fluids are tested for Hägglunds Drives motors (ISO/DP 6071).FluidApprovedSealsInternal paintHFA: Oil (3-5%) in water emulsionNo--HFB: Inverted emulsion 40-45% water in oilYesNitrile (std motor)Not painted*HFC: Water-glycolYesNitrile (std motor)Not painted*HFD:R - Phosphate estersYesVitonNot painted*HFD:S - Chlorinated hydrocarbonsYesVitonNot painted*HFD:T - Mixture of the aboveYesVitonNot painted*HFD:U - Other compositionsYesVitonNot painted*HFD synthetic fluidsEnvironmentally acceptable fluidsFluidApprovedSealsInternal paintVegetable */**Fluid HTGYesNitrile(std motor)-Synthetic **Esters HEYesNitrile(std motor)-*Vegetable fluids give good lubrication and small change of viscosity with different temperature.Vegetable fluids must be controlled every 3 months and temperature shall be less than 45 C(113 F) to give good service life for the fluid.**Environmentally acceptable fluid give the same servicelife for the drives, as mineral oil.23
Choice of hydraulic fluidDown rating of pressure data and basic rating lifeDown rating of pressure, for motors used in systemswith fire resistant fluids, the maximum pressure formotor given on data sheet must be multiplied withfollowing factors:HFA-fluidnot fit for useHFB-fluid0,7 x maximum pressure for motorHFC-fluid0,7 x maximum pressure for motorHFD-fluid0,9 x maximum pressure for motorDown rating of basic rating life, for motors used insystems with fire resistant fluids, the "expected basicrated life" must be multiplied with following factors:HFA-fluidHFB-fluidHFC-fluidHFD-fluidnot fit for use0,26 x expected life with mineral oil0,24 x expected life with mineral oil0,80 x expected life with mineral oilFiltrationThe oil in a hydraulic system must always be filtered and also new oil from your supplier has to be filteredwhen adding it to the system. The grade of filtration in a hydraulic system is a question of service life v.s.money spent on filtration.In order to obtain stated service life it is important to follow our recommendations concerning contaminationlevel.When choosing the filter it is important to consider the amount of dirt particles that the filter can absorb andstill operate satisfactory. For that reason we recommend a filter with an indicator that gives a signal when itis time to change the filter cartridge.Filtering recommendationsBefore start-up, check that the system is thoroughly cleaned.1. In general the contamination level in our motors should not exceed ISO 4406 19/15 (NAS 10).2. For heavy-duty applications the contamination level should not exceed ISO 4406 16/13 (NAS 7).3. When filling the tank and motor case, we recommend the use of a filter with the grade of filtration β10 75.Explanation of "Grade of Filtration"Grade of filtration β10 75 indicates the following:β10 means the size of particle 10µm that will be removed by filtration. 75 means the grade of filtration of above mentioned size of particle. The grade of filtration is defined asnumber of particles in the oil before filtration in relation to number of particles in the oil after filtration.Ex. Grade of filtration is β10 75.Before the filtration the oil contains N number of particles 10µm and after p
