Long-Term Availability
Liebherr crawler dozers are designed with economy in mind. Comprehensive,
purpose-built protection packages help minimize downtime and keep machines
operating even in the harshest working conditions.
Cab Comfort
Excellent all-around vision, low sound levels, and a workplace designed to offer
maximum comfort - the perfect environment to keep the operator focused and
productive. Dust is kept out by the pressurized cab and by means of special air
filtration options.
Intelligent Cooling System
The hydrostatically driven fan controls the operating temperature independently
of engine speed. As an option, it reverses its direction automatically at regular
intervals, thus removing all debris that might have accumulated on the radiator.
The risk of overheating is virtually eliminated, and safe operation is guaranteed.
