The designers of the Scientific and Technical Center of KAMAZ PJSC have developed a unique KAMAZ-6559 dump truck designed for quarry work in autonomous mode.
The car, created jointly with the specialists of the Bauman Moscow State Technical University within the framework of the project "Creation of a family of electromechanical unmanned dump trucks of large capacity in the interests of the extractive industries of the Russian Federation", became a continuation of the Kamaz line of quarry dump trucks. The unmanned KAMAZ-6559, named "Jupiter 30", was created for the transportation of loosened rock mass or ore using a deserted technology – without the presence of people in the dangerous zone of heavy trucks and excavators. Due to this feature, there is no cab for the driver in the design of the car.
The Jupiter was originally designed as an autonomous vehicle for working in a quarry. It is equipped with all the necessary equipment. It has special cameras, 2D and 3D lidars, ultrasonic sensors, radars, protected from dust, dirt, moisture and vibrations. GSM antennas and GPS/GLONASS navigation are also available. Both bridges are pivoting, due to which the car has good maneuverability," said Sergey Nazarenko, chief designer of innovative vehicles at the Scientific and Technical Center of KAMAZ PJSC.
A dump truck with a 4x4 wheel formula has a hybrid transmission according to a sequential scheme, with buffer batteries for energy recovery during braking and downward movement. Also, to improve operational characteristics, a shuttle mode of movement has been implemented on the dump truck. The car, after loading without U-turns, goes to the unloading place and, having unloaded without U-turns, goes in the opposite direction in order to get under a new loading without maneuvers. All this allows you to save fuel, reduce the cycle time of the dump truck and increases its efficiency.
The autonomous car is equipped with a KAMAZ inline six-cylinder engine 910.12-450 with a working volume of 11.9 liters. The engine drives an electric generator that provides energy for the traction motor and charges traction batteries. All–wheel drive in the absence of a transfer case is carried out thanks to the use of two traction motors in the dump truck - one for each axle.
The length of the dump truck is 8769 mm, width – 2709 mm, height – 3499 mm. The curb weight of the chassis is 23 tons, both axles (front and rear) have the same load – up to 25 tons each. The car is capable of transporting up to 30 tons of cargo fully automatically or remotely, while its speed is limited to 56 km/h.
A dump truck platform with a bottom and sides made of special steel of increased thickness is used for transporting mined ore or overburden. Thanks to its heating by the exhaust gases of the engine, the issue of freezing wet winter soil has been resolved. The volume of the dump truck is 21.5 cubic meters.
"Jupiter 30" is an absolute novelty and a world premiere. This is the first sample of a new line of rigid-frame KAMAZ dump trucks of the Jupiter family. The following models will be more load–lifting, the company will be engaged in their development over the next years," Sergey Nazarenko shared.
Currently, specialists of KAMAZ PJSC and Bauman Moscow State Technical University are working on setting up all vehicle systems. After the landfill tests at the KAMAZ Scientific and Technical Center, the dump truck will be transferred to the SDS-Ugol holding company for trial operation in the Chernihiv section (Kemerovo Region).
