KOMATSU D39PX-24 Bulldozer

Entretien facile

Planned maintenance and daily checks are the only way to ensure long service life from equipment. That’s why Komatsu designed the D39EX/PX-24 with conveniently located maintenance points to make necessary inspections and maintenance quick and easy.

Opération d 'économie d'énergie

HST avec contrôle électronique

The D39EX/PX-24 is equipped with Komatsu-designed HST that allows for Quick-Shift or variable speed selection. The HST consists of dual-path closed-circuits, with two variable displacement piston pumps and two variable displacement travel motors. Hydrostatic steering eliminates steering clutches and brakes, providing smooth, powerful turns. Fully electronic control provides complete automatic shifting and enables smooth control. Moteur speed is controlled using an electronic fuel control dial.

Le nouveau moteur Komatsu conforme à la réglementation sur les émissions

New regulations effective in 2014 require the reduction of NOx emissions. In addition to refining the U.S. EPA Tier 4 Interim technologies, Komatsu developed a new Selective Catalytic Reduction (SCR) device in-house.

Grand moniteur LCD haute résolution multilingue

A large, user-friendly color monitor provides easy-tounderstand information for the operator. Excellent screen visibility is achieved with a high resolution LCD monitor that is easy to read at various angles and lighting conditions. Simple and easy-to-operate switches and function keys facilitate multi-function operations. The monitor displays data in 26 languages.

Conception modulaire

One of the design goals behind the creation of the D39EX/PX-24 was to manufacture a more durable machine. This was achieved by reducing component complexity and using a strong modular design for increased serviceability and durability. Steel castings reduce the number of welds, improving rigidity and strength.

Pédale simple ( décélérateur / pédale de frein) à utiliser pour le contrôle de la vitesse, pendant le fonctionnement

Machine operation is simple because brake function has been integrated into the decelerator pedal. Machine travel speed can be controlled using one pedal. The pedal function can be changed by a mode selector switch.

Leviers du système de commande et de contrôle Palm ( PCCS)

Komatsu Les poignées PCCS ergonomiques créent un environnement d 'exploitation avec un contrôle complet de l'opérateur.

Système de train d 'atterrissage à liaison parallèle ( PLUS)

Komatsu's PLUS rotating bush design provides less downtime, longer wear, and with up to 40% lower undercarriage maintenance costs. Rotating bushings eliminate the cost and downtime for bushing turns, and strengthened rollers and links increase wear life up to two times. With PLUS, individual links can be replaced with common track tools.

Bouteur PAT avec pas réglable

A power angle power tilt dozer blade with adjustable blade pitch system is available on the D39EX/PX-24. The hydraulic blade tilt and angling function expands versatility and productivity in a variety of applications and manually adjustable blade pitch.

Ventilateur basculant arrière à entraînement hydraulique

The D39EX/PX-24 utilizes a swing-up fan with a gas strut-assisted lift system to provide easy access to the (side-by-side) radiator, oil cooler and charge air cooler. The hydraulic fan has a cleaning mode which enables the fan to rotate in the reverse direction to help clear off objects that are restricting air flow.

Gardiennage et accessoires robustes

Mode de travail sélectionnable

P mode is the mode designed for powerful operation and maximum production. E mode is designed for general dozing applications, providing adequate speed and power, while saving energy. For fuel reduction and energy savings, the monitor panel allows the operator to easily switch between working modes, depending on working conditions.

Visibilité inégalée de la lame

The D39EX/PX-24 incorporates Komatsu's super-slant nose design. Komatsu's innovative design provides excellent blade visibility for improved machine control and increased efficiency and productivity.

Fonction d 'arrêt automatique au ralenti

Komatsu auto idle shutdown automatically shuts the engine down after idling for a set period of time to reduce unnecessary fuel consumption and exhaust emissions. The amount of time before the engine is shutdown can be easily programmed from 5 to 60 minutes.

Moteur

Entraînement final

In-shoe mounted, axial-piston-type travel motors, with integrated two-stage planetary gear reduction. Compact, in-shoe mount reduces risk of damage by debris. Bolt-on sprocket ring with triple labyrinth seal design.

Système hydraulique

Système de détection de charge à centre fermé ( CLSS) conçu pour un contrôle précis et réactif, et pour un fonctionnement simultané efficace.

Transmission hydrostatique

Dual-path, hydrostatic transmission provides infinite speed changes up to 8.5 km/h 5.3 mph. The variable capacity travel motors allow the operator to select the optimum speed to match specific jobs. Travel control lock lever and neutral switch.

Poids de fonctionnement ( APROXIMATE)

Poids du tracteur :
Including Cabine ROPS, U frame for power angle tilt dozer, rated capacity of lubricant, coolant, full fuel tank, operator, and standard equipment.

Capacités de recharge de service

Système de direction

Palm Command Control System (PCCS) joystick control for all directional movements. Pushing the joystick forward results in forward machine travel, while pulling it back reverses the machine. Simply tilt the joystick to the left or right to make a turn. Tilting the joystick fully to the left or right activates counter-rotation.
