With the introduction of the new generation of articulated dump trucks, Liebherr now offers a full line of earthmoving products. Apart from a comprehensive product portfolio of earthmoving machines for diverse applications, the new TA 230 articulated dump truck is now available to customers in the U.S. market.
The extremely robust, powerful and all-terrain machine is primarily designed for overburden transport and for the mining industry. The articulated dump trucks are also a useful assistant for larger infrastructure projects. Thanks to their optimal structure gauge, they can also be used for special applications, such as tunnel construction.
Maximum performance in challenging off-road applications. The new TA 230 Litronic has a clever machine concept, which has been developed specifically for challenging off-road applications. New designs in the front-end area create maximum ground clearance for superb off-road performance. For example, in the TA 230 Litronic the powershift transmission is positioned safely and compactly under the operator’s cab and the exhaust gas aftertreatment is safely installed behind the operator’s cab in a space-saving manner, whereby a large slope angle could be generated.
The newly designed, solid articulated swivel joint creates excellent off-road capability: It allows independent movements of front and rear end, thus ensuring maximum maneuverability. The robust and positive-locking swivel joint with tapered roller bearing is perfect for the shear stresses arising during use, withstands maximum loads and provides optimal force distribution.
The front and rear axles of the machine are secured via sturdy A-rods at the articulated swivel joint and at the rear end. The focus here was on maximum ground clearance in the development: Both the front axle suspension with A-rods and shock absorbers at the articulated swivel joint and the position of the separate and oscillating A-rods of the rear axles at the rear end provide maximum ground clearance.
Superb driving performance and combined pulling force. A powerful 6-cylinder construction machinery engine with a displacement of 732.3 cu. in. and 265 kW (355 hp) is installed in the new TA 230 Litronic, which complies with the requirements of exhaust emissions stage Tier 4f. A robust and efficient drivetrain with automatic 8-speed powershift transmission ensures optimal force distribution.
With the actively controlled longitudinal differential locks, automatic traction control is also available for the TA 230 Litronic: As soon as slip occurs at an axle, the torque is cleverly transferred to the axle or axles with traction. The new Liebherr dump truck has an excellent driving performance and enormous pulling force, even in the most difficult ground conditions and on challenging gradients. Maximum safety is always guaranteed thanks to optimal adhesion.
More material movement in a shorter time thanks to optimized dump bed. The large and robust dump bed of the new TA 230 Litronic is designed for effective transport. Numerous improvements have been made for quick and efficient loading and unloading, as well as safe transport of the material.
The front of the dump bed is straight and the sills are low, so that loading with a wheel loader, for example, is easily possible across the entire length. A standard, innovative weighing system shows the current payload during the loading process on the display in the operator’s cab. An optional loading light on both sides at the back of the operator’s cab shows the loading level outdoors.
In order to accelerate the release of the material during unloading, the inner edges of the new dump bed are tapered. Thanks to the optional dump bed heating with exhaust gas management, unloading can also be easily completed at cooler temperatures. The two tipping cylinders at the side give the TA 230 Litronic high tipping pressure. The load can be tipped against the slope easily and quickly.
During transportation the long chute at the end of the dump bed ensures minimal material loss. The dump bed volume can be increased with the optional tailgate. Thanks to the large opening width, tipping of large and bulky transported material is easily possible. Even with the tailgate, the overall width of the TA 230 Litronic is still below 9 ft.,11 in. – this allows the machine to be easily and quickly transported on the low-loader.
Optimal visibility and safety. The spacious cab of the new TA 230 Litronic provides ideal conditions for comfortable and safe operation. Not only does it offer unobstructed and panoramic views through the front windshield, the inclined hood of the machine also allows operators to keep an optimal view of the driving area while working and articulating the machine.
A touch display with integrated rear camera also increases visibility in the rear area. In the soundproof cab, ergonomically arranged control elements facilitate intuitive operation of the machine. Various trays and built-in storage greatly expand the workspace area. The offset steps, as well as the large operator’s door, allow convenient and safe access to the cab.
The new lighting concept with LED headlights ensures improved visibility and safety – both for the machine operator and everyone outside. For example, dipped-beam headlamps with integrated high beams illuminate the road and the extra powerful, optional LED headlights on the front can illuminate the entire working area.
The lighting at the rear of the dump bed and another light package at the mudguards light up the maneuvering areas at night. The modern LED design light provides additional visibility of the Liebherr dump truck and thus increased safety on the construction site. The new Liebherr dump truck also has an optional LED access light, which provides extra safety when getting into the operator’s cab.
Modern assist systems and adaptive steering system increase comfort and safety. The modern assist systems installed in the new TA 230 Litronic support the machine operator, thus increasing safety and comfort during operation. Apart from a hill start assist, a speed assist is also available. With the hard stop function, the end position damping of the dump bed lifting cylinders can be activated or deactivated at the touch of a button. The dump bed lift is limited for work in a height-critical area with the aid of the height limit.
The speed-dependent steering provides additional driving comfort: The adaptive steering system continuously adapts the ratio of the steering movements to the current speed. This allows easy and accurate maneuvering at low speeds, but also accurate steering at higher speeds, as well as fewer steering corrections when cornering or taking bends.
Maintenance-friendly machine design. With the intelligent machine check-up and a service-oriented machine design, the new TA 230 Litronic boasts an optimized maintenance concept. The Liebherr dump truck automatically performs a daily check itself thanks to the clever sensor technology: The machine runs through an inspection catalogue at the start, where levels of engine oil, coolant and the central lubrication system are checked for the nominal state.
Any deviations are shown on the display in the operator’s cab. As a result, the daily set-up times can be reduced, costs can be saved and the durability of the components can be extended.
The electrohydraulic opening hood, as well as an integrated, folding ladder with non-slip steps, provide easy, safe and clear access to the entire engine compartment. All relevant service points are visible and easily accessible. Maintenance work can be performed comfortably and safely from a platform.
