Mining Dump Truck
Articulated dump truck (ADT), namely articulated hauler,usually have the characteristics of full-wheel drive. They are a kind of earthwork transport machinery with strong versatility in large-scale construction of mining industry and various industries. Because of the special structure, they can adapt to harsh climate, transport goods on rugged terrain and have high availability. The key of articulated trucks is to connect the front and back parts. The principle of the articulator is similar to that of the universal joint. Each part has its own frame, the former part is equipped with engine and its operating system, cab; the latter part is equipped with hopper and dump device, which connects the power part of the car with the loading part through the hinged head. The hinged head is directly connected with the front frame or rear frame of the car, and the vehicle has good driving performance by connecting the vertical and horizontal hinges. Some parts of the car can turn left or right to 45 degrees in the horizontal plane relative to the other parts, or even "fold" together. In addition, the front and rear frames can rotate independently and independently around the common longitudinal axis in a plane perpendicular to the common longitudinal axis. Because the folding angle of the two parts of the frame forms when the articulated truck turns, the turning radius of the outer contour of the vehicle decreases, while the turning radius of the inner contour increases, which makes it possible for the truck to pass in a narrow passage. The two parts of the body may rotate relative to the common longitudinal axis. It can obviously reduce the wheel runout in the vertical direction of the suspension system.
Main Advantages
Power
Tier3 stage high power electronic control engine is adopted, which has stronger power.
Vehicle Frame
Vehicle frame is composed of articulated hitch, front frame and rear frame.
Articulated hitch allows the rear frame to free oscillate and rotate, relative to the front frame, ensure all of the driving wheels shall be good contact with the ground in order to provide excellent mobility and stability of the high speed transport capacity. The articulated hitch is used of casting.
All of the frames are made of high quality high strength low alloy steel, The main parts adopts casting, improving the strength of the frame. All of Important weld is tested 100% by ultrasonic testing.
Body
Body adopts full welder structure with HB400 high strength wear-resistant steel plate. Bigger Dump angle, larger ground clearance and lower loading height make it very helpful for rapid loading and unloading of materials. Flat tail warped type, rock type, installing rubber suspension block.
Suspension
Hydro-Pneumatic suspension combined with the A-frame to ensure that the vehicle has good vehicle stability and off-road performance. SWADT400 articulated dump truck suspension structure can lower the impact caused by harsh road, improve riding comfort and handling stability.
Steering
High quality variable plunger pump provides oil source, flow amplifying hydraulic steering, good feeling steering wheel, high precision steering response, stable steering. Equipped with second steering accumulator.
Hoisting
Hoisting is completed by a valve group to manipulate single secondary double-acting,telescopic cylinder.
Brake System
SWADT400 adopts self-oil cooled disc brakes system, ensure the vehicle highly reliable and long lifetime. Even in the muddy road, SWADT400 also function responsively. The large-capacity, continuously cooled, wet-multiple disc brakes also function as a highly responsive retarder which
gives the operator greater confidence at higher speeds when travelling downhill.
Safety Device
The cab equipped with rear window protection grill, The three-point seat belts, Escape hammer, emergency stop button, Rotating lamp, Reversing warning, Steering locking lever, Boxcar support bar, Assisted steering and brake accumulator, slip resistant surface, guardrail, etc.
Cab
The FOPS cab is built from high strength steel, meeting FOPS standard,without A column design, with the broad space and vision. The fully-equipped cab provided all kinds of display instrument, alarm, lighting, control switch, On-board computer, electric Windows, tilting and telescoping steering wheel, electric windshield wiper cleaners, colored glass, air conditioning.
