Mining Dump Truck
Electric drive mining trucks are mechanized vehicles, which are both on-road and off-road transportation mediums in the regions of heavy mining and constructions. These are haul vehicles used to continuously shift the mined and waste materials to refining and dumping grounds, respectively.
The frame is composed of a pair of longitudinal beams and four cross beams, all of which work together to form a closed structure. The longitudinal and cross beams all adopt a box-type cross section structure, able to eliminate the source of bending stress and cracking concentration.
The frame is made of high-quality, low-alloy and high-strength steel, with casts adopted as the main parts to improve the strength of the frame. All important welds (100%) have passed ultrasonic testing.
It has adopted the computer aided design and finite element optimization analysis.
The front hubs and steering knuckles are made respectively from high quality cast and forged steel featuring reliable durability.
The rear axle housing is made from high strength alloy steel, with all important welds (100%) subject to ultrasonic testing. The rear axle housing is connected to the frame by means of a knuckle bearing to ensure its enough rotational freedom relative to the frame and thus prolong the service life of the frame and the rear axle housing. A tie rod is adopted to limit the rear axle housing to achieve a simple structure featuring easy maintenance.
The SWORT1900EX electric drive dump truck adopts a stiffness-variable independent candle-type front suspension symmetrical on the left and right sides to ensure reliable wheel alignment as well as steady and comfortable riding. The oil/ air suspension is hinged to the frame and the axles (front and rear) by means of an articulated bearing, with the exposed portion of the piston rod protected by a scalable sleeve, able to fit changes of the load and road conditions, absorb impacts rapidly, attenuate vibration and ultimately ensure smooth driving.
Front suspension: independent candle-type suspension, oil/air-suspending cylinders; Rear suspension: vertical triangular swing-arm suspension, oil/air-suspending cylinder.
It adopts a flow-amplified hydraulic steering system with the steering oil supplied by an imported variable plunger pump, so the steering wheel can offer better road sensing, able to achieve high-precision and stable steering. The emergency steering is powered by an accumulator.
