Productivity
By maximizing payload while minimizing cycle time, Liebherr high-horsepower
equipment moves more tons per hour.
Largest payload
Ultra class trucks have proven to be a more productive means of moving material.
As the designer and manufacturer of the fi rst 400 ton (363 t) mining truck, Liebherr
has been at the forefront of this successful industry solution. By hauling more per
cycle, the T 284 allows Customers to maximize the return on their investment and
to meet production targets with fewer trucks or in less time.
Unmatched performance
The combination of the T 284’s effi cient Litronic Plus AC drive system, its highpower (up to 3,000 kW / 4,023 HP) engine, and low gross vehicle weight leads
to fast haul cycle times with higher speeds on grade if compared to other trucks
in its class.
Flexible engine options
The T 284 supports multiple engine options with power ratings up to 3,000 kW
(4,023 HP). With application-specifi c recommendations from Liebherr, Customers
are able to select the engine that will allow the truck to meet productivity targets
while minimizing fuel consumption.
Drivability
Liebherr is committed to designing mining trucks that operators want to drive.
The T 284 fulfi lls this commitment and promotes driver effi ciency with its superior
comfort, acceleration and handling.
Lightweight design
Liebherr’s trademark low EVW is
achieved by utilizing an electric drive
system combined with a lightweight
frame. Hauling the largest available
payload with a lighter truck maximizes
Customer productivity.

Wheel motors
The T 284’s AC induction motors effi ciently
convert electrical power into mechanical
torque. Fewer electrical losses translate
into higher rimpull forces for faster cycle
times and increased fuel economy.

Effi ciency
Effi ciency is a key ingredient for a successful mining operation. Liebherr mining
equipment enables Customers to enjoy unrivaled performance while reducing
cost per ton.
Litronic Plus technology
Developed and built by Liebherr, the proven Litronic Plus drive system determines
the optimal way to extract power from the diesel engine. Effi cient loading of the
engine is critical to minimize fuel consumption and maximize performance.
Intelligent power usage
Engine power usage is optimized by running auxiliary components such as
pumps, fans and motors only when needed. Fuel is conserved when the engine
is idling and more power is available to accelerate the truck and climb grades
when necessary.
Long life components
Components are built to perform in the most extreme mining conditions in order
to allow more time between overhauls and to reach their maximum operational life.
Engine / Fuel system
The T 284 offers reliable engine options
with the latest fuel injection technology
for cleaner combustion and reduced
fuel consumption. Customers can
expect reduced maintenance and lower
fuel costs.

Frame
The T 284’s frame is designed according to
international weld fatigue guidelines, and
is fabricated according to American Welding Society standards. This steel structure
includes cast components in strategic
areas and hollow box rails with fully welded
internal stiffeners. These choices ensure a
durable, lightweight frame.
