Engine
A very low fuel consuming engine which conforms to European requirements for “low exhaust
emission” Tier 2 in accordance with directive 97/68/EC.
Particularly suitable for urban work, these engines have significantly reduced noise levels, one of
the lowest fuel consumptions on the market.
Engine rotation speed checking via an electric potentiometer.
Manual return to idle, control on RH control lever.
Engine pre-heating.
High performance filtration circuit enables oil change intervals to be extended to every 500 h.

longer hydraulic fluid life-time
(fluid change interval now 5000
hours).

Attachments
To meet user requirements,
CASE "short radius" crawler
excavators are suitable for every
type of work-site.
These machines are mainly used
on the following types of work:
•
Construction and maintenan-
ce of high speed roads and
urban streets.
•
Construction in residential
areas.
•
Demolition.
•
Forestry work.
•
Machine hire companies.
To provide best possible profita-
bility in the various sorts of
work encountered, machine
configuration needs to be able to
be changed quickly and easily:
of implement, using supple-
mentary hydraulic functions
(swing, tool orientation, etc.)
•
Reduced maintenance costs
using EMS (Easy Maintenance
System) which is standard on
the boom foot and head lin-
kages. This system, which is
also used on the heavy CX
machines, provides a conside-
rable reduction in maintenan-
ce intervals (every 1000 h).
Cab
With CASE machines, "smaller
machine dimensions" don't
mean that there is less space for
the operator. The CX75SR cab
has the same level of comfort
and convenience as the standard
models in the CX range; it is
integrated with the upperstruc-
ture and therefore does not
affect manoeuvrability on 360°
swing. It’s still wide enough to
provide the operator with maxi-
mum comfort and all the advan-
tages of a "standard" machine,
including mechanical suspen-
sion and a multi-adjustable dri-
ver's seat, with a storage com-
partment to the rear LH of the
seat.
Mechanical suspension, multi-
adjustable driver’s seat (with a
storage compartment to the rear
LH of the seat).
The cab has a large roof win-
dow , enabling continuous chec-
king of the bucket position when
THE ”CASE” ANSWERS
•
A choice of one-piece or double
offset boom for digging verti-
cal walled trenches, regardless
of their depth.
•
A choice of diffe ren t dipper
lengths.
•
“MULTIFIT” quick coupler .
•
Supply to the most varied types
the attachment is fully retracted.
For operator comfort, the cab
is insulated from vibration
and noise by four elastofluid
mountings.

Undercarriage
LC type undercarriage providing
excellent stability (as a result of
its length) and loading capacity
comparable to machines of
standard dimensions.
Steel or rubber tracks are
available.
Upper and lower tracks equip-
ped with bushings and seals.
Travel motors protected and
incorporated in the under-
carriage.
Track tension adjustable by
grease cylinder .
DOZER BLADE
Dozer blade control lever at
console height to the right hand
side of the cab. Dozer blade
movement by a central hydrau-
lic cylinder.
Dozer blade width ............. 2.32 m
Dozer blade height .......... 0.450 m
Maximum raising height 0.415 m
Maximum underground
lowering depth................. 0.205 m
SPECIFICATIONS
(per track set)
Number of upper rollers.......... 1
Number of lower rollers .......... 5
Number of track pads............ 39

Upperstructure
The “short radius” CX75SR has special specifications compared to “standard” models:
•
Shorter upperstructure radius for the rear part.
•
The boom foot is positioned close to the upperstructure swing axis so as to have the minimum attachment
front swing radius.
•
Cab is within the upperstructure swing radius .
•
The width of upperstructure is close to the width of the undercarriage (using standard track pads).
•
Counterweight and general stability of the machine provides lifting capacities identical to “standard”
machines.

RESPECT OF ENVIRONMENT
The excavator respects the
European “reduced noise level”
as per directive 2000/14/EC Phase 2.

Lifting capacity
- Lift capacities are taken in accordance with SAE J 1097
- Lift capacities shown in kg do not exceed 75% of the tipping load or 87% of the hydraulic lift capacity.
- Capacities that are marked with an asterisk are hydraulic limited
-Ifthe machine is equipped with a quick coupler, subtract the weight of the quick coupler from the load shown in the tables to calculate the real
lifting capacity.
