Liebherr has introduced its new generation of articulated dump trucks. The robust, powerful and all-terrain ADTs are primarily designed for overburden transport, aggregates, light mining and large infrastructure projects.
The newly designed, solid articulated swivel joint allows independent movements of front and rear end, thus ensuring maximum manoeuvrability. The robust and positive-locking swivel joint with tapered roller bearing is ideal for the shear stresses arising during use, withstands maximum loads and provides optimal force distribution. 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.
Powerful drive with maximum traction
The new TA 230 Litronic features a 6-cylinder engine delivering 265 kW / 360 hp. A robust 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 transferred to the axle or axles with traction.
More material movement in less time
The large and robust trough of the new TA 230 Litronic is designed to transport a 28-tonne payload. Numerous improvements have been made for https://www.aga-parts.com/hitachi-construction/ quick and efficient loading and unloading, as well as safe transport of the material. The front of the trough is straight and the sills are low so that loading with a wheel loader, for example, is 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 trough are tapered. The two tipping cylinders at the side give the TA 230 Litronic high tipping pressure. During transportation, the long chute at the end of the trough ensures minimal material loss. Even with the tailgate, the overall width of the TA 230 Litronic is still below 3m, allowing the machine to be easily and quickly transported on the low-loader.
Newly developed operator’s cab
The newly developed, spacious operator’s cab of the TA 230 Litronic features panoramic windows without any struts, as well as a short, inclined bonnet for excellent visibility. The driver always has an optimal view of the driving, working and articulating area of the machine. A touch display with integrated rear camera also increases visibility to the rear.
The new lighting concept with LED headlights ensures improved visibility and safety – both for the machine operator and everyone around the machine. Dipped-beam headlamps with integrated high beam illuminate the road and the extra powerful, optional LED headlights on the front of the can illuminate the entire working area. The lighting at the rear of the trough and another light package at the mudguards light up the manoeuvring areas at night. The modern LED design light provides additional visibility of the Liebherr dump truck and thus increased safety on the construction site.
Modern assist and adaptive steering systems
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 trough lifting cylinders can be activated or deactivated at the touch of a button. The trough 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 makes easy and accurate manoeuvring at low speeds possible, but also accurate steering at higher speeds, as well as fewer steering corrections when cornering or taking bends.
Maintenance-friendly machine design
Featuring intelligent machine check-up and a service-oriented design, the Liebherr dump truck automatically performs daily checks itself thanks to the sensor technology. The machine runs through an inspection catalogue at the start, where levels of engine oil, coolant, and the central lubrication system, for example, are checked. 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 bonnet, 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. Refuelling with fuel or urea solution is also done easily and safely from the ground.
