Siemens electromechanical transmission system has significantly fewer contactors compared to DC electric transmissions. The number of servicable units is also less. Due to the use of highly reliable components, it provides an unprecedented reduction in operating costs.
The ratio of power and speed characteristics allows to bring the truck characteristics closer to the parameters of the ideal theoretical continuously variable transmission.
No gear shifting is required, the current and voltage supplied to the traction motors determine the torque and speed of the truck, providing a smooth power change during movement.
The control system algorithm optimizes drive system parameters and provides lower operating costs and greater productivity of transportation.
Taking into account the lower initial cost of dump trucks with electromechanical transmission, the absence of units subject to wear improves performance and reduces the cost of operation.
