D Series MIDI CRAWLER EXCAVATORS

Main features

Uncover the new CASE D series MIDI EXCAVATOR

  • The CX85D SR is a short radius model, which can work in only 2920 mm (1630 mm front swing + 1290 mm tail swing) and it has the same mono boom design of larger excavators. It is offered also in the OFFSET version which increases the working area without re-positioning the machine.
  • The CX90D MSR has a SWING boom design, which makes it perfect when maneuverability and maximum reach are the priority. The generous swing angles (left 80°; right 45°) combined with excellent visibility in every direction contribute to its great success.

 

NEW MONITOR AS A 50 TONNES CASE EXCAVATOR!

More features

The new 7” full-color LCD monitor, has got a new design, higher contrast, 5 more menu, as a 50 tonnes CASE excavator! Live key parameter are now available: on rpm, pumps, battery tension, consumption per hrs, week, liters accumulated, residual time for engine cooling, engine hours, travelling time, rotation, operation and real working time or even hammer time utilization, and more.

Every machine is equipped with the efficient automatic A/C, which creates a pleasant climate inside the cab with its 6-vent system combined with a high wind flow of 430 m 3/s. Proportional controls of the first and second auxiliary circuits can be ordered as optional for maximum controllability and comfort, when the machine is used with hydraulic powered attachments.

NEW STAGE V ENGINE: THE MOST POWERFUL IN THE SEGMENT

20% more power (kw); 45% greater displacement; 56% more torque

The new STAGE V engine is a highly reliable 4-cylinder 68 HP Yanmar engine, largely used in the market. The new engine is the most powerful in the segment and meets the latest EU standards for engine exhaust emissions that set new limit for particle number (PN) and further reduced particulate matter (PM) levels.

 

More energy saving, more power but with less fuel

The new Yanmar engine makes less effort (works nice and easy) and can better support the pump with higher torque even against high load pressure: engine is less overloaded and consumes less (-4,5% in SP mode and -3,2% in H mode) confirming the best in class speed.

 

Noise perception

Different frequencies generated by the more generous Yanmar engine give a better general feeling on operators ears.

Noise inside cabin (69 dB) remains:

BEST in class across all competitors!

 

Auto cleaning DPF with no impact on daily working time

To meet the STAGE V regulations, a new regenerating after treatment system has been made necessary to collect and burn the Particulate Matters, preventing their release in the atmosphere. The system is self cleaning and auto regenerating through oxidation (increasing post combustion) and managing and controlling the high pressure fuel injection. All is done automatically without any intervention by the operator who will just need to work normally. Operator can check the PM accumulation status directly on the monitor and even percentage details of PM and ashes can be displayed through the service menu.

IMPRESSIVE SPEED AND LESS CONSUMPTION

High performance hydraulics

The new CASE MIDI D series confirm to have the best in class speed and a lower fuel consumption. Reasons behind is a greater balance of the different components of the machines (engine, pump) and the Pump Transition reduction Control (PTC) inherited from higher class CASE excavators, which is a very accurate system that continuously monitors machine operations and then decreases pump loads whenever possible, adapting to the type of job. As a result, hydraulic power is available on demand, pump and engine are less overloaded and fuel consumption is minimised.

 

BEST IN CLASS LIFTING CAPACITY

Both CX85D and CX90D have the greatest lifting capacity in the industry; as per ISO standards: CX85D lifts 1700 Kg (@4 m reach, 0 cm from the ground, BLADE UP); CX90D lift 1800 kg (@4 m reach, 0 cm from the ground, BLADE UP).

BOOM TYPES FOR EVERY NEED

  • Offset boom - version on CX85D:
    It increases the working area without re positioning the machine. Comfortable side digging due to excellent view of the bucket or attachment at work. The minimum working distance allows for operations in very tight spaces.
  • Mono boom - version on CX85D:
    It can work in only 2920 mm (1630 mm front swing + 1290 mm tail swing). The same mono boom design of larger excavators provides outstanding robustness and reliability.
  • Swing boom - version on CX90D:
    Excellent maneuverability and maximum reach. The generous swing angles (left 80° ; right 45°) combined with excellent visibility in every direction contribute to a great productivity.

 

TOP CLASS BREAKOUT FORCE

Thanks a perfect balance among engine, pump, booms and undercarriage, also digging performance are impressive:

  • bucket digging force: 56.9 kN
  • arm digging force: 39.5 kN

 

HYDRAULIC SOURCED FROM BIGGER CASE EXCAVATORS

Three different working modes (SP, H, Auto) add more fuel savings without compromising on performance as in the upper range model of Heavy CASE excavators.

  • A-MODE is most appropriate for grading, lifting and precision work.
  • H-MODE delivers the best balance between productivity and fuel economy.
  • SP-MODE provides extra speed and power for the most demanding jobs that require maximum productivity.

CABIN AS BIG EXCAVATORS

Incredible full round view

The large cab with its huge glazed area provides outstanding visibility all round and on to the bucket or attachment allowing easier and safer operations.

Work safely in tight spaces

The short tail and front swing radius design make D-Series mid size excavators the best solution to work efficiently in confined spaces. The compact design minimises disruption in urban and road job sites, as well as the possibility of hitting something when swinging the upper structure of the machine. Swing cylinder and door are well protected.

The smooth and round shape design of the CASE D series MIDI cab was studied for maximum reliability and functionality. The CX85D SR can work in a space of less than 3 meters wide!

 

COMFORTABLE AND SAFE CAB

Outstanding roominess

Same cab as larger CASE SR excavators, which means: a front space (from front glass to seat back) 1115 mm; access space (from front glass to console end) 580 mm; foot space (from front glass to seat) 640 mm.

Comfort and durability. Best in class cabin noise level

The cabin remains a predominant distinctive CASE DNA when we talk about comfort and durability. Impacts and vibrations on the cab are effectively absorbed by the 4-point fluid mounting system, providing a pleasant ride and low noise levels inside the cab which is the best in class in the industry. The structure of the cab with its square section pillars contribute also to its robustness and durability. New options is now available for seat heater and lumbar support.

Safety first

The cab of D-Series midis meet ROPS and FOPS Level 1 safety standards. FOPS Level 2 as well as front stone guard protections are available as optional features. In the new Midi D series, a remote emergency stop is now located on cabin floor left side for ease access also from outside.

SAFE AND EASY MAINTENANCE

The hydraulic system, filters, engine and radiators can easily be reached from ground level, allowing intuitive, safe and fast maintenance operations. Cooling system has been improved and optimized to simplify maintenance. Battery switch is easier to use and to reach.

Convenient access from the cab

The A/C internal re circulation filter and the fuse box are easily accessible from inside the cab.

Simplified diagnostics

The built-in monitor system includes 13 self-diagnosis system that alerts the operator in case of clogged air, oil or hydraulic filters, and gives reminders of due maintenance by remaining hours prior change, preventing damage to the machine.

New fuel filter supply line

New main fuel pre filter water separator sensor linked to a dedicated message on machine monitor to drain water when level in filter is too high. Additional safety filter (maintenance free) to protect the engine from dust: no need to flush after filter replacement.

 

CASE EASY MAINTENANCE SYSTEM (EMS)

Uses stratified bushing and plated pins on the pivot points, which holds grease longer, increases lubrication intervals and prevents rattling:

  • Greasing interval for all pivot points (bucket excluded) : 1000 hrs
  • Greasing bucket interval: 200 hrs

OIL SAMPLING PORTS

For engine and hydraulic oil.

QUICK COUPLER PROVISION

Available as option.
