2 Technical design

2.1 Functions Hägglunds DUcThe Hägglunds DUc provides the hydraulic motor(s) with required hydraulic oil flow and pressure together with system control functionality.

The DUc is divided into six basic sizes depending on electric motor power and hydraulic flow requirements:• Medium frame - Single pump - two compartments

(MS2)• Medium frame - Tandem pump- two compartments

(MT2)• Large frame - Single pump - two compartments (LS2)• Large frame - Tandem pump - two compartments (LT2)• Large frame - Single pump - three compartments (LS3)• Large frame - Tandem pump - three compartments

(LT3)

The Hägglunds DUc supports functionality for one or two driven machine shafts.Functions as cold/warm flushing and brake circuits for the hydraulic motors are available.The Hägglunds DUc is available for.

• Power ranges from 11 kW to 2x500 kW/15 hp to 2x670 hp.

• Flow ranges up to 3 000 lpm/792 gpm at 1 500 rpm for single pump (3 600 lpm/951 gpm at 1 800 rpm)

• Working pressure max 350 bar/5076 PSI.

The Hägglunds DUc has an embedded control system with a large variety of configurable functionality to simplify thecontrol and monitoring of the hydraulic drive. The control system is pre-programmed, easy to reconfig-ure and contains functions as:• Variable-speed control• Speed feedback• Power limitation• Industrial fieldbus communication• Analog and digital signal monitoring• Pressure control (torque control)

and application specific functions as: –Friction control –Shedder control –Synchronized control

All internal sensors are pre-wired to the control system. Monitoring of the drive unit sensors is handled internallyaccording to Fig. 2.

The DUc can be delivered without control system if required. All electrical wiring for sensors and pump con-trol will be wired to a junction box. Card for pump control can be assembled as an alternative.

On DUc MS2 and LS2 are the connections to sensors and actuators wired directly the control system/junction box.

On DUc MT2, LT2, LS3 and LT3 are the connections to sensors and actuators distributed via I/O boxes with a multi cable on the control system/junction box side and M12 connectors on the sensor/actuator side, see Fig. 3. The actuators/sensors are individually connected with a multi cable from the M12 connectors on the I/O box.

The cables has an outer sheet of PUR that is halogene free but the conductors has an insulation with PVC that is not halogene free.

5 Testing

5.1 Delivery testAll Hägglunds DUc are production tested before delivery from the production plant, the purpose of the production test is to verify the customer demands in respect to fun-ction, performance and surface finish.The delivery test of Hägglunds DUc are performed by authorized personal and documented in a test protocol, based on technical specification of the DUc. All components are controlled and set so that only minor adjustments are needed at commissioning on site. Setting and control of pressure, voltage, flow, etc. is done with calibrated measure equipment.

5.2 Noise test (optional at order)Noise test of Hägglunds DUc are performed by an external company. The measuring conditions are according to ISO 3746 and ISO 11202. The measurements are performed with 3 different load cases:• Idling• Workingpressure(0%flow)• Hydraulicpressureatapprox.50bar(100%flow)

The reported result shows the measured sound pressure level (LPA) at 1 m distance from the drive unit and the calculated sound power level (LWA).Noise test and its certificate is available on request, see Table 8.

5.3 Factory acceptance test (optional at order)

The following will be shown during the factory acceptance test (FAT):• Limited delivery test of the DUc (pressure settings)• Review of order specific documentation.

Date for attendance at FAT will be notified approx. 14 days before the delivery date.

6 Logistics

6.1 GeneralThis chapter describes the standard procedure for packing of Hägglunds DUc with accessories. It also describes how Hägglunds product are shipped and how they should be handled during transportation and installation. It also point out requirements for storages of Hägglunds products on site

6.2 ShippingAll items are not assembled in the DUc due to practically, safety and logistically reasons.

Items not assembled at delivery. Main electric motor• DUc MS2: Motor always assembled• DUc LS2, MT2, LT2, LS3, LT3: Motor never assembled

Cooler assembly• DUc MS2: Air-oil cooler up to HDC 085 is assembled /

HDC 090 and HDC 100 never assembled Plate and tube water-oil cooler always assembled

• DUc LS2: Air-oil cooler never assembled Plate water-oil cooler always assembled Tube water-oil cooler never assembled

• DUc MT2: Air-oil cooler never assembled Plate water-oil cooler always assembled. Tube water-oil cooler never assembled

• DUc LT2: Air-oil cooler never assembled Plate and tube water-oil cooler never assembled

• DUc LS3: Air-oil cooler never assembled Plate water-oil cooler always assembled Tube water-oil cooler never assembled

• DUc LT3: Air-oil cooler never assembled Plate and tube water-oil cooler never assembled

Small items not assembled at delivery • Cabinet feet• Filter element - spare

All items delivered separated from the Drive Unit are protected with VCi plastic bags.

6.3 PackagingHägglunds products are packed in wooden crates or on pallets. That will give adequate protection against mecha-nical damage and atmospheric corrosion during shipping, transportation, handling and storage.

The DUc is then covered and sealed with a plastic hood. Labels on the hood show the centre of gravity for the DUc

Desiccant bags

Desiccant bags are place inside the DUc to absorb moisture thus atmospheric corrosion is avoided during shipping and storage.

Fig. 4: Desiccant bags

Fig. 5: Plastic bag

Fig. 6: Crate with rain protection

A wooden crate is then built for cover and mechanical protection of the DUc.As standard, the top of the crate is rain protected with a plastic film and is on all vertical walls marked with centre of gravity, fork lifting points and weight.

6.3.1 Packing procedure DUcThe standard packing procedure for a DUc is divided into several steps.



6.3.2 Packing procedure other itemsThese items are packaged in plastic hoods and a VCI foam pad is placed inside the hood before it will be sealed. This gives an adequate protection against atmospheric corro-sion during shipping and storage. These items are placed in separate wooden crates or on pallets.

6.3.3 CratesThe crates are made of plywood that conforms to ISPM No. 15.

The building process of the crates are that walls and roof are nailed together, after that a number of metal straps are tightened around the crate.

6.4 Lifting methodsThe DUc package is designed for forklift truck handling and an unpacked DUc can also be lifted with ropes/chains. Items that are delivered in separate crates or on pallets, these are only designed for forklift truck handling and are always marked with the weight.

6.5 Storage conditions at siteThe DUc (including parts delivered separately) should be stored indoors. The plastic hood in a crate or on a pallet should not be open or removed before installation.

6.5.1 Storage condition on site for DUcAt delivery, the DUc is protected with desiccant bags to absorb moisture and sealed with a plastic hood. This provides sufficient atmospheric corrosion protection for indoor storage up to 12 months from delivery date.If storage time exceeds 12 months the desiccant bags has to be exchanged, the crate must be opened to access the plastic hood.

6.5.2 Storage condition on site for other itemAt delivery, the separate delivered items are protected with VCI foam pads and sealed with a plastic hood.This provides sufficient atmospheric corrosion protection for indoor storage up to 18 months from delivery date.

If storage time exceeds 18 months, the VCI protection has to be extended.
