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.
Main Advantages
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.
