CAT CAT®D9 Large bulldozer

Product Feature

● Achieve the lowest possible cost of ownership

Design concept:CAT Large bulldozer

Ensure high productivity in all applications

Ensure operator safety, comfort and efficient operation

Make the most of technology

For easy maintenance and repair

Ensure durability

● Bulldozers for your application

High productivity in any application:

Overhead sprocket and suspended undercarriage work together:

Increase traction,Enables the operator to have a smooth driving experience in all conditions

Make the components easy to remove,Thereby reducing maintenance time.

Overhead sprockets transmit implement impact loads to the main frame,Make the final drive、Axles and steering components are protected from strong impact

Application

Overburden split soil

Production bulldozing

Reclamation

Winch towing

Device cluster support

Site maintenance

Stacking

● Improve the efficiency of dozing operation

Improve performance and efficiency

Torque converter with stator clutch - High efficiency,Low fuel consumption

Bogie suspension - Not easy to slip,Higher productivity

Differential steering - Large load,Fast and smooth handling

Not easy to slip,The yield is increased

D9 Use bogie suspension device,Conform track to ground condition,The ground area can be increased,Pecially on rough, hard ground.。Higher traction means less slip、The balance is higher、The ride is smoother。

Large load,Smooth handling。

D9With differential steering,Large blade loads can be moved smoothly with one turn。The differential provides a compact turning radius.,Can maintain high travel speed during cornering to maintain high productivity。The planetary power shift transmission is available through the Advanced Productivity Electronic Control System(APECS,Advanced Productivity Electronic Control System)Achieve smooth speed and commutation。

Torque converter with stator clutch

1)Under low load condition,When no torque increase is required,Automatically release the stator,Thus:

– Increase the efficiency of the power train

– Reduce fuel consumption

2)Automatic locking during higher loads and deceleration

3)The operator will not perceive a significant change in the display of less information

Fully adjustable air suspension seat(Heating/Refrigeration)

Labor-saving electronic gearbox、Turn、Ripper and Dozer Control

Automatic temperature control

Designed for comfort

Save effort,Reduce noise and vibration

Suspension undercarriage absorbs shock,Reduce the impact load,Keep the track grounded

Increased productivity

Larger information display、Faster、The effect is better

High-definition color touch screen

In-car 41 languages

Fewer buttons and screens in the cab — Intuitive Operator Setup Menu
