D41E-6 Komatsu D41E-6 Specifications & Technical Data (1996—2003)

Modular designed power train units

The modular design allows easy removal and installation of any individual unit for shorter downtime. Each modul is sealed off individually, preventing oil leakage and oil contamination during operation and maintenance.

Test ports

Oil pressure test ports for the power train are centralized on the right hand side of the operator platform for easy access.

Walk-Around

Palm command joysticks provide intuitive control with the left hand joystick managing all tractor motion and the right hand joystick controlling all blade movements. The Komatsu SA6D102E-2A turbocharged and aftercooled diesel engine delivers an output of 82 kW (110 HP) with excellent productivity while meeting European Stage II and EPA TIER II emissions regulations. The hydrostatic driven engine cooling fan is controlled automatically, reducing fuel consumption and operating noise levels. Gull-wing engine side doors allow for easier and safer servicing. The high capacity power angle tilt dozer combines the highest power with outstanding productivity. The super-angle blade facilitates transportation of D41-6. Blade tilt lines are completely protected. The Komatsu hydrosift transmission offers single lever control of speed with 3 forward and 3 reverse options and directional changes.

Reversible hydrostatic driven cooling fan

If the machine is operating in adverse conditions, the operator can reverse the hydraulic driven engine cooling fan from inside the cab by turning on a switch on the control panel, facilitating cleaning of the radiator fins.

Easy-to-operate work equipment control lever

With the Closed-center Load Sensing hydraulic System (CLSS), blade lever stroke is directly proportional with blade speed, regardless of the load and travel speed. This results in superb, fine controllability.

Hydraulic System

Closed-center Load Sensing System (CLSS) designed for precise and responsive control and for efficient simultaneous operation. Hydraulic control unit: All spool control valves externally mounted beside the hydraulic tank. Gear-type hydraulic pump with capacity (discharge flow) of 86 ltr/min at rated engine rpm. Relief valve setting 20,6 MPa / 210 kg/cm². Hydraulic cylinders Double-acting, piston type. Hydraulic oil capacity (refilling): Power angle tilt dozer 44,0 ltr. Control valves: 3-Spool control valve for power angle tilt dozer. Positions: Blade lift Raise, hold, lower, and float. Blade tilt Right, hold, and left. Blade angle Right, hold, and left. Additional control valve required for ripper. Positions: Ripper lift Raise, hold, and lower.

Electronic monitoring system

An electronic monitoring system prevents minor problems from developing into major ones. All meters and gauges are controlled by a microcomputer, which provides a wide range of machine data.

New suspension seat

D41E/P-6 uses a newly designed heavy-duty suspension seat. Fore and aft sliding rails and suspension spring have been newly designed to increase durability and rigidity. The new seat provides excellent support, improving riding comfort.

Tough undercarriage

Large link height, pins and bushing diameter and double-flanged track rollers ensures extended life of undercarriage. The newly designed sprocket increases lifetime of the heavy-duty undercarriage of the D41E-version and the heavy-duty abrasion resistant D41P-version.

Flat bottom frame

A flat bottom frame and the monocoque track frames provide good maneuverability in muddy terrain by preventing mud from building up under the frame.

Gull-wing engine side covers

Gull-wing engine side covers open 140° by assistance of a gas-spring cylinder. Both the engine and the auxiliary components can be checked easily.

Operator comfort

Operator comfort is essential for safe and productive work. The D41E/P-6 provides a quiet, comfortable environment where the operator can concentrate on the work at hand.

Comfortable ride with new cab damper mounting

D41E/P-6 Space Cab™ uses a newly designed cab damper that provides an excellent shock and vibration absorption capacity with its long stroke. The viscous mount cab damper greatly reduces shocks and vibrations while dozing and ripping. As a result, both the vibrations and noise level in the operator compartment are reduced to the minimum.

Ergonomical joystick

All steering, direction, and speed changes are made by a left-hand single joystick control. If the operator wants to move the machine forward and to the left, he simply moves the joystick forward and to the left. Gear changes can be done by twisting the steering lever. The machine responds to the movement of the lever, providing the operator a feeling of natural control with Komatsu's joystick.

Durability

Because fewer components mean greater reliability, we’ve designed a simple hull frame made of a thick, single plate. Track frames have a large-section construction for maximum rigidity. Even the box-section construction of the blade back beam is reinforced, all with durability in mind.

Dozer Equipment (Power Angle Tilt Dozer)

D41-6 uses box construction of the back plate while using high-tensile-strength steel in moldboard to ensure extended service. Hydraulic hoses for blade angling and tilting are covered with steel plates for protection from damage.
