, ultra class, rigid frame, two axle, diesel-electric, AC powertrain haul trucks designed and manufactured in the United States by Liebherr Mining Equipment Co. The Liebherr T 282 series is no longer in production, however, due to the extended service life of this equipment, many are still in operation on mines around the world. The T 282 series is succeeded by the Liebherr T 284.

with a payload capacity.


Development and testing

Liebherr developed a payload capacity haul truck for large-scale mining operations. Engineers at Liebherr Mining Equipment Newport News Co. designed the T 282 to have the lightest Empty Vehicle Weight (EVW) respective to its payload capacity. The T 282 was the first mining haul truck designed by Liebherr following the company's acquisition of existing haul truck manufacturing company, WISEDA, LTD. The first T 282s were tested extensively at Liebherr's proving grounds.


Features

The T 282 standard features included air suspension seats, double shell concept for safety, thermal and acoustical isolation, emergency engine shutdown, environmentally controlled cab, safety glass with tinted windshield, cast steel components in stress areas, double a-frame front suspension system with inclined king pin, back up warning alarm, and more. Optional features included L&M radiator, monitoring systems, special paint, cold climate kit, AM/FM radio with cassette player, electric starter, engine heater, canopy spill guards, body liner, and more.


Engine

The T 282 is powered by an electric drive system.


Manufacturing and assembly

No longer in production, the T 282 B was assembled at the Liebherr Mining Equipment Co. production facility in Newport News, Virginia. The chassis (frame, axle box, engine, radiator, fan, and alternator) are assembled for shipment alongside the superstructure (operators' cabin, grid box, and drive system). All other components are implemented on-site with the customer.


T 282 B

The 2004 Liebherr T 282 B offers a payload of up to and was built specifically for high-production mining applications worldwide. The T 282 B succeeds the T 282.


Development and testing

In October 2003, Liebherr introduced the T 282 B haul truck for large-scale mining operations to reduce cost and increase productivity. The large dump body allowed for each T 282 B operating to carry more material per haul, with fewer trips from loading tool to fill pile. Engineers at Liebherr Mining Equipment Newport News Co. designed the truck to have the largest haul truck payload capacity in the world at the time of release; with one of the lightest Empty Vehicle Weight (EVW) at , making for a highly productive truck with a relatively low operating cost. The T 282 B requires fewer operating hours to achieve the same level of production as trucks produced by other companies. The low EVW was achievable due to the lightweight AC drive system, use of less heavy components, and "stress flow" design, which allowed for lighter steel structures and casings, which in turn yield a lighter and stronger frame. The first T 282 Bs were tested extensively at Liebherr's proving grounds.


Public debut

, Germany, on March 29, 2004. The T 282 B is the successor to the T 282, designed in Newport News, a payload capacity, diesel/AC electric drive haul truck introduced in 1998. At the time of its launch in 2004, the T 282 B offered the largest haul truck payload capacity in the world, and remained unmatched in payload capacity for over four years.


Features

The T 282 B standard features include an in-cab display screen displaying truck status, fuel consumption, and payload monitoring and downloads. All Liebherr mining trucks include HVAC for operator comfort. The T 282 B is fully compatible with the Liebherr Trolley Assist System, built to save on fuel consumption without sacrificing productivity. Trolley assist is only available for trucks with electric drive systems.


Powertrain and engine

The T 282 B is powered by a diesel/electric powertrain. The diesel engine is coupled to a Siemens-Liebherr AC electric drive system. Fully loaded, the T 282 B can achieve a top speed of . Two diesel engines are available: * a DDC/ MTU 20V4000, V20 *

Braking systems

The T 282 B features an electric dynamic retard with continuously rated, fan-forced air over stainless steel resistor grid, with a dry disc secondary braking system. Additional features include extended speed range, cruise control, two speed over speed, slip slide traction control, front/rear service brakes, hydraulic accumulators, park brakes, and filtration.


Manufacturing and assembly

No longer in production, the T 282 B was assembled at the Liebherr Mining Equipment Co. production facility in Newport News. The chassis (frame, axle box, engine, radiator, fan, and alternator) are assembled for shipment alongside the superstructure (operators' cabin, grid box, and drive system).

T 282 C

The 2010 Liebherr T 282 C offers a payload of up to with an Empty Vehicle Weight (EVW) of and was built specifically for high-production mining applications worldwide. The T 282 C succeeds the T 282 B, introduced in 2004. The T 282 series is succeeded by the Liebherr T 284.


Development and testing

In 2010, Liebherr Mining Equipment Newport News Co. designed the T 282 C for reduced cycle time and to have the highest payload-to-EVW in its class, at . The combination of its high power diesel engine with the efficient Litronic Plus drive system maximizes productivity while reducing fuel consumption. Engineers incorporated the Litronic Plus drive system and improvements to the electrical systems, including machine health and monitoring systems to offer real-time diagnostics for instantaneous improved reliability and maintainability. The first T 282 Cs were tested extensively at Liebherr's proving grounds.

Features

The T 282 C standard features include the Litronic Plus drive system with real-time fault warning and detection system, CAN Bus technology for flexible monitoring, truck diagnostics, air ride seats with 3 point seatbelts, improved HVAC, greater visibility, and an integrated colour touch screen in operator cab (displays truck status, fuel consumption, payload monitoring, and downloads).


Litronic Plus IGBT AC drive system

Designed for mining environments, the control cabinet with integrated rectifier is liquid-cooled, and includes a ground fault warning and detection system. The pressurized cabinet for dust control requires fewer components than GTO drive systems.


Tier 2 engine

The T 282 C engine is a Tier 2, EPA-compliant diesel MTU/DD 20V4000 engine, configurable up to . Water-cooled turbo chargers and exhaust manifold keep the engine cool, while the ADEC engine control module monitors fuel consumption and exhaust temperatures at multiple points.


Improved electrical systems

The T 282 C electrical system has a number of improvements over the T 282 B, including moving the rectifier to the control box, reducing the wiring with Harnessflex conduit, protection against dirt and water ingress via heat shrink connectors, and reducing voltage drip for the starting circuit.


Manufacturing and assembly

No longer in production, the T 282 C was manufactured and assembled at the Liebherr Mining Equipment Co. production facility in Newport News. The chassis (frame, axle box, engine, radiator, fan, and alternator) are assembled for shipment alongside the superstructure (operators' cabin, grid box, and drive system). All other components are implemented on-site with the customer.


Specifications


Transportation of the T 282 series

Due to its exceptional size and weight, the T 282 series cannot be driven on public roads. The T 282 series was shipped in component form to the customer site before undergoing final assembly.


Cost of the T 282 series

No longer in production, the price of each T 282 model varied based upon customer specification and quantity ordered. Each T 282 truck cost US$4–5 million and Liebherr previously sold dozens of the T 282 series each year, primarily to
