Comfort
The redesigned workplace offers the operator a remarkable degree of comfort.
Spacious, quiet and designed with ergonomics in mind, Liebherr comfort cabs
offer the ideal conditions for fatigue-free, concentrated work. Excellent visibility
facilitates safe and precise operation.
A top-class cab
Ergonomics The ergonomically-designed operator’s workplace
offers the ideal environment for relaxed, productive
work. All instruments and operating controls are laid
out comprehensibly and within easy reach.
Low sound values The sound level in a Liebherr cab is far below the
legal requirements. The PR 734 and the PR 744
boast exemplary noise values thanks to effec-
tive cab sound-proofing and state-of-the-art, quiet
diesel engines.
Outstanding visibility The integrated ROPS/FOPS protection structure
and large-area glazing afford the operator optimum
outward visibility.
Straightforward and precise control
Single-joystick control All travel movements can be controlled easily and
precisely with only one joystick – including the
“counter-rotation” function.
Continuously
variable control
Speed selection is continuously variable without
gearshifting and therefore without interrupting draw-
bar pull.
Safety in
every situation
The crawler tractor is driven with positive power
transmission at all times, even on gradients. The
self-locking action of the system (hydrostatic drive)
allows the operator to control braking simply by
reducing joystick movement.
The machine is equipped with an automatic parking
brake that is activated when the machine is stationary.
Instrument panel
• The instrument panel is ideally
positioned in the operator’s
field of vision.
• Automatic monitoring, display
and warnings in the event of
abnormal operating conditions.
Well-designed details
• A generous storage space
including a 12V socket for
operating a cooler is standard.
• The flexible, multi-way
adjustable seat with 3-way
adjustable armrests provides
a comfortable workplace.
• Further details such as a
sliding side window, tinted
glazing and a foot rest
enhance the operator’s
comfort.
