High-performance belt conveyor unit with high material flow
The high-performance, hydraulically height-adjustable, rear discharge conveyor with a movable counterweight can be slewed to the right and left by 90° and enables the loading of mining trucks with payloads of up to 100 tons. What’s more, the operator can continuously vary the speed of the belt independent of the engine speed to reduce belt wear dependent on the material volume and the piece-size of the mined material.
Outstanding operator comfort
Entirely new standards are set by the dust-sealed and air-conditioned positive-pressure cabin with fresh air filtration, which effectively prevents the ingress of dust into the operator’s workplace. Mounted on the front left chassis column, the operator’s cabin with all-round glazing is decoupled from the machine body and can be rotated by 90° in both directions. Up to six cameras can also be installed to provide even better all-round vision. Various automatic functions also contribute to the operator’s comfort, reduce the risk of fatigue, assist the operator in the achievement of high productivity rates and make the overall process more efficient.
Conservation of resources and environmental awareness
These days, the reduction of carbon emissions, noise, dust and vibration while maintaining consistently high extraction rates and productivity is more important than ever before. With the new surface miner, Wirtgen offers innovative technologies that minimise impact on the environment and conserve valuable natural resources. Thanks to the reduction of carbon emissions by low specific fuel consumption, an efficient water management system and effective solutions for the minimisation of dust pollution, the 280 SM(i) shows that ecological and economic considerations are actually compatible and closely interconnected.
