Above on the page there're some Service PDF Manuals for LIEBHERR Dump Trucks.
Liebherr also produces truck cranes.
Liebherr began series production and delivery of the TI 274 heavy haul trucks at the beginning of 2010.
The features of this truck were a significant increase in carrying capacity, and a reduction in operating costs through the use of electric motors for each wheel, and the use of high-strength rubber for wheel tires.
From the main technical characteristics of the dump truck, the following characteristics can be distinguished:
- carrying capacity - 290 tons;
- operating power - 2238 kW;
- curb weight - 460 tons;
- working speed - 64km / h.
To develop such outstanding performance, mining truck manufacturers have long abandoned the use of the main diesel plant as a propulsion unit, modern mining trucks use diesel only to generate electrical energy, which is supplied to power numerous electric motors.
Changes in the design of the suspension frame: an additional support structure was added to the load-bearing structure of the bucket support of the dump truck and a connection was established between the main tipping mechanism and the front of the chassis.
Thanks to such changes, the load is not directed to the middle of the supporting frame, but directly to the ground.
The load platform stopped pressing on the middle of the frame, significantly reducing the bending moment.
To reduce risks, cast parts are installed in the places where the greatest loads are concentrated.
Unlike other Liebherr truck models, the tipping cylinders, which support the weight of the loading platform, are pushed forward and take the load constantly, and not just during the tipping of the platform.
The tipping cylinders are supplemented with an external support to withstand a large part of the influencing forces from internal loads that occur in the cylinders during operation.
The guide cylinders restrict the lift cylinders from lateral movement while the platform is being raised.
The rear wheel design of Liebherr TI274 truck includes two twin wheels located on the rear axles and independent suspension for each wheel.
The movement of the wheels is done by separate electric motors, which allows each wheel to rotate at its own frequency.
This increases traction, improves traction and reduces tire wear when cornering.
At the same time, the load on the individual tires is reduced.
Both rear axles have the ability to move 4 degrees to the sides, so that each tire maintains the same pressure when hitting uneven ground.
