  General

  The DUe drive unit provides the hydraulic motor(s) with required hydraulic oil flow and pressure together with system control functionality.

   

  The drive unit is divided to 4 basic sizes depending on electric motor power and hydraulic flow requirements:

  Compact (C)

  ?

  Small (S)

  ?

  Medium (M)

  ?

  Large (L)

  ?

  The drive units are built with one, two or three hydraulic compartments.

  C has one compartment.

  S, M and L can have 2 or 3 compartments depending on required number of pumps. 2 and 3 compartment contains one with the hydraulic oil tank and one or two with the electric motor/pump combination. All compartments are assembled in one common cabinet.

  The basic combinations will be DUe C1, DUe S2, DUe S3, DUe M2, DUe M3, DUe L2 and DUe L3.

  A single compartment cabinet can be added to the M and L variants for higher flow requirements, for emergency drives or as standby unit.

   

  The drive unit supports functionality for one or two driven machine shafts.

  Functions as cold/warm flushing and brake circuits for the hydraulic motors are available as options.

  The drive unit has an embedded control system with a large variety of configurable functionality to simplify the control and monitoring of the hydraulic drive.

  The control system is pre-programmed and easy to configure 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

  ?

  For detailed functionality and configuration, see data sheet for Hägglunds Spider Control System, EN777.

  The DUe drive unit can be delivered without control system if required. All electrical wiring for sensors and pump control will be wired to a junction box assembled on the side of the drive unit. Driver card for pump can be assembled as an alternative in the junction box or in a separate box.

  Monitoring of the drive unit sensors must be handled externally (see chapter "Symbols/Circuit diagrams" - Figure "Monitoring logic diagram").

   

  The drive unit is available for:

  Power ranges from 11 kW to 2 x 500 kW.

  ?

  Flow ranges up to 3000 l/min at 1500 rpm (3600 l/min at 1800 rpm).

  ?

  Working pressure max 350 bar.

  ?
