Preface
Preface
Hägglunds Drives is one of the worlds leading manufacturers of large hydraulic
Drive Systems. A leading position, made possible by unbeatable service spirit
and of continuing development of both products and markets all over the world.
Our drives are to be found in most industrial and marine segments, where
there are extremely high demands for efficiency and reliability. Our main office
and production plant is in Mellansel, Sweden and we have our own sales- and
representation offices in some 40 different countries.
Our high quality Drive Systems, are based upon our unique hydraulic piston
motors, developed through a wealth of experience accumulated over 40 years
in marine and industrial areas.Today this ongoing development work has re-
sulted in the powerful COMPACT industrial motor. New, as well as established
technical solutions, contribute to the creation of this product.The most desirable
features and operating reliability have been designed in this hydraulic motor.
This manual provides necessary information for installation and maintenance
of the motor. In order to find particular information, just search for the wanted
section as listed in the table of contents. However, changes in the equipment
may occur. We therefore reserve the right to introduce amendments in the
manual as we deem necessary without notice or obligations.
This Installation and Maintenance Manual is va-
lid for motors manufactured after 2006-06-01. For
older motors please contact your nearest Hägg-
lunds representative.

1. GENERAL
General
It is of high importence that the Safety precautions are always followed, if you are
unsure about something, please don´t hesitate to contact your nearest HD-office
for advice.
WARNING is used to indicate the presence of a hazard
which can cause severe personal injury, death, or
substantial property damage if the warning is ignored.
DANGER is used to indicate the presence of a hazard
which will cause severe personal injury, death, or
substantial property damage if the warning is ignored.
CAUTION is used to indicate the presence of a hazard
which will or can cause minor personal injury or property
damage if the warning is ignored.
In this manual you will find the following signs which indicate a potential hazard, which can or will
cause personal enjury or substantial property damage. Depending on the probability of the hazard,
and how serious the injury or property damage could be, there are three levels of classification.

1.3 Functional description
Fig. 1 The COMPACT CBP 140
Hägglunds hydraulic industrial motor COM-
PACT CBP is of the radial-piston type with
a rotating cylinder block/hollow shaft and a
stationary housing.The cylinder block is moun-
ted in fixed roller bearings in the housing. An
even number of pistons are radially located in
bores inside the cylinder block, and two valve
plate directs the incoming and outgoing oil to
and from the working pistons. Each piston is
working against a cam roller.
When the hydraulic pressure is acting on the
pistons, the cam rollers are pushed against the
slope on the cam ring that is rigidly connected
to the housing, thereby producing a torque.The
cam rollers transfer the reaction force to the
piston which are guided in the rotating cylinder
block. Rotation therefore occurs, and the torque
available is proportional to the pressure in the
system.
Oil main lines are connected to ports A and C
in the connection blocks and drain lines to ports
D1, D2, D3 or D4 in the motor housing.
The motor is connected to the shaft of the
driven machine through the hollow shaft of
the cylinder block.The torque is transmitted
by splines.

Technical data
2. TECHNICAL DATA
There are three distinct cases:
Case 1:
The motor works in braking mode. Required
charge pressure at the inlet port is according
to diagram below.
Case 2:
The motor works in driving mode only. Required
back pressure at the outlet port corresponds to
30% of value given in diagram below, but may
not be lower than 2 bar (29 psi).
Case 3:
The motor is used with 2-speed valve. Requi-
red charge pressure at inlet port for valve is
according to AC-3.1 Accessories.
The hydraulic system must be such that the
motor will recieve sufficient charge pressure at
the low-pressure port. This applies to all types
of installations.
Note:
The diagram is valid for 1 bar (15 psi) case pressure. With increasing case pressure the charge
pressure must be increased accordingly. The graph is valid when 8 ports are used. Max casing
pressure is 3 bar (43,5 psi)(for 1% of the operation time evenly divided, pressure peaks of max 5
seconds upto 8 bar (116 psi) is allowed). Max permitted case pressure at stand-still is 8 bar (116
psi).
2.1 Recommended charge
pressure
In hanging load applications, charge
pressure at motors connection must
be according to graph below under
all conditions.

2.2 Sound from a complete installation
Hydraulic motor
The hydraulic motor is a known noise level.
(Tables of sound data - see subsection 4.9 in
the Engineering Manual).
Driven unit
The driven unit is an unknown sound source
(for us) but can through certain information
probably be obtained from the supplier. When
securing the torque arm of a hydraulic motor to
the foundation or casing of a driven machine,
it is highly important to study the construction
of the foundation or casing. This may well be
the most important factor to consider, since
many structures may give rise to resonance,
resulting in severe noise problems.
Remarks:
Background noise
The background noise can not normally be
influenced but is usually known or easy to
measure.
Pump unit
The pump unit is a known noise level.
Pipe noise
The pipe noise is probably the source of the
majority of mistakes in installations: all pipe
clamps should be of vibration insulating type
secured to concrete ceiling, wall or floor.
Securing to non-rigid metal structures or
structures is likely to give resonance and
should be avoided.
