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 3 basic sizes depending on
electric motor power and hydraulic flow requirements:
• Small (S)
• Medium (M)
• Large (L)
The drive units are built with two or three hydraulic compartments which 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 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 such as:
• Variable-speed control
• Speed feedback
• Power limitation
• Industrial fieldbus communication
• Analog and digital signal monitoring
• Pressure control (torque control)
and application specific functions such as:
– Friction control
– Shredder control
– Synchronized control

manual Hägglunds Spider, RE 15330-WA.
