Special Applications

Improved D-esign for D-urable perfomances

• The boom and arm have been redesigned according to the latest stress analysis criteria to reduce stress points.
• The undercarriage has been redesigned and reshaped 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 size of the undercarriage component 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.

Smooth control with the CASE Intelligent Hydraulic System

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

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.

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) increases 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 of inactivity. Both are manually switchable.

Working modes easily adapt to every work load

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.

A retractable undercarriage is available for easy transportation to your jobsite as an alternative to the LC chassis. Different sizes of track shoes are available, including the 600 mm double grouser shoes for CASEs when greater traction is needed.

EU Stage IV/TIER4 Final compliant CASE engines on the D series

• 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 uptime 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 Turbocharger to ensure a fast transient response of the engine while minimizing fluid consumption.
• 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.

The ultimate interior cab configuration

• Superior cab structure with ample legroom for the operator.
• Fully adjustable workstation.
• New ergonomically designed high back seat with air suspension for excellent comfort.
• Optional seat tilting adjustment and seat heater.
• Top class features include the 178 mm colour LED Monitor, bluetooth tuner and Radio, spacious storage compartment, 12v accessory plug, clipboard holder, mobile phone holder, warm and cool box, fuse box service connection, storage tray and ergonomic arm rest.

Soundproof pressurised cab

• The cushioning system lowers noise and vibration levels for the operator’s ultimate comfort.

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 fi tted travel alarm for greater safety on the jobsite 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.

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.
• Solid platform (80 cm wide) on top of the engine compartment to provide a stable base for the technician working on the engine compartment.

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.
• Standard 100 l/min refueling pump with automatic cut off.
• 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.
• Hydraulically-driven cooling fan contributes to lower noise output and improvements in fuel consumption. The reversing mode helps to reduce maintenance needs.
