D Series CRAWLER EXCAVATORS

Improved D-esign for D-urable performances-

• The boom and arm have been re-designed according to the latest stress analysis criteria, to reduce stress points while maintaining weight optimization to ensure the best lifting performance.

• New high strength casting parts with joined hinge flanges reduce stress and increase durability.

• The undercarriage has been re-designed and re-shaped to facilitate the welding process, enhancing the reliability of the fabricated structures.

• The One-Side-Slope lower frame design reduces the time needed to clean the undercarriage.

• The thickness of the structural plates has been increased, especially in those parts where a high level of protection is required for components.

Accurate, simple and robust design for high durability

• True to CASE's enviable reputation for reliability and durability, the D-Series delivers leading design solutions and manufacturing quality.

• Wide choice of arm solutions, including the heavy- duty arm with reinforcement plate and bars on the bottom side.

Smooth control with the CASE Intelligent Hydraulic System

• The proven CASE Intelligent Hydraulic System (CIHS) delivers impressive machine control with unrivaled energy savings in all cycle time phases (digging, boom up and swing, dumping).

ROPS cab and FOPS level II

A safe working environment for the operator:

• Reinforced structure of the cab compliant with ROPS/FOPS requirements.

• Standard head protection approved to FOPS Level 2.

• Wide offering of optional front guards.

• Optional factory fitted travel alarm for greater safety on the job site around the machine

Safety-minded cab structure

Cab designed to create a perceptibly safe and secure working environment:

• Ample glazed surface.

• Rear and side view camera.

• Unique 178 mm LED monitor with continuous camera view.

• Efficient use of space with grouped engine, cooling and after-treatment systems to provide excellent rear visibility.

• Optional LED lighting package provides a deeper and wider visibility coverage of the area around the machine when working after dark.

Safe Access To Upper carriage

Solid and robust platform and handrails

• Wide, robust and comfortable steps for safe access to the top of the hood.

• Solid handrail for protection on the top of the hood.

• Non slip-plates and top hood cover are supported by 2 gas pistons and secured by 2 mechanical stops when open.

A wide platform (up to 60 cm) on top of the engine compartment to work safely on the engine box.

CASE stays grounded

• All filters and regular fill points are grouped for easy access.

• Engine oil change intervals set at 500 hours.

• Radiator and cooler cores mounted side by side for easy access for cleaning and more efficient cooling. Dust-proof net in front of the radiators is accessible from the ground.

• Standard 100 l/min refueling pump with automatic cut off reduces downtime for regular fills.

• Optional hydraulic and engine oil sampling port accessible at ground level for easy oil check.

• Battery Shutdown Switch for safe maintenance on the electrical system.

• All the D-series crawler excavators feature the Extended Maintenance System (EMS) bushings, providing 1,000 hour greasing intervals on all pins except the attachment linkage.

High performance hydraulics control

• - The new electrically controlled pumps and a bigger main control valve deliver faster cycle times.
• - Oil flow can be adjusted according to working needs, or increased smoothly while starting travel and boom down.
• - As a result, the machine responsiveness to operation load is multiplied, resulting in cycle times up to 12% faster than the previous generation.

Working modes easily adapt to every work load

The familiar working mode systems offers 3 power modes to match different customer needs.

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

Auto Power boost automatically increases hydraulic pressure according to the operation's demands.

Great performances with low fuel consumption

CASE advanced energy management provides solid fuel saving opportunities and lower emissions, and helps to prolong the life of the machine. It consists of 5 Energy Saving controls:

• - Torque control decreases main pump loads to prevent a drop in engine rpm, with improved sensitivity to control/ monitor main pump loads
• - Boom Economy Control (BEC) Increased fuel efficiency during boom lower and swing operations, like dump unloading
• - Swing Relief Control (SWC) Carefully manages the hydraulic power distribution in slewing operations to deliver the most efficient flow and pressure.
• - Spool Stroke Control (SSC) Creates an automatic pressure adjustment during digging and leveling operations.
• - Idle functions: the Auto Idle function lowers engine rpm after 5 seconds of lever inactivity whatever the throttle position, while the Idle Shutdown function shuts the engine down after a pre-setted time. Both are manually switchable.

EU Stage IV/TIER4 Final compliant CASE engines

• - Maintenance-free SCR and DOC-only solution
• - No Diesel Particulate Filter (DPF) or regeneration are required as no solid particles remain trapped into the system, resulting in maximum up time and lower operating costs.
• - High engine efficiency of the latest generation, electronically controlled, high pressure common rail with multi-injection engine ensures great performances and low fuel consumption.
• - CASE adds a variable geometry turbo charger to increase exhaust gas re-circulation efficiency without losing power.
• - The system is also very economical in its use of AdBlue, which is just 2.5%- 3% of fuel consumption. The large AdBlue tank only needs to be refilled every 10 fuel refills, so that no time is wasted.
