At MINExpo in Las Vegas, Dana Incorporated launched the new Spicer Electrified e-Powershift transmission, a modular and flexible two-speed solution that provides power take-off (PTO) functionality for electrified mining vehicles.
Offering high efficiency and superior performance in a compact package that simplifies the mining industry’s transition to electrification, the twin-motor version of the e-Powershift transmission supports continuous outputs up to 322 hp (240 kW), while the single-engine configuration is rated for 161 hp (120 kW) of continuous power. Its flexible, high-power-density design makes it suitable for a wide range of applications, including small and medium-sized loaders and trucks used in underground mining, as well as construction wheel loaders, large forklifts and terminal tractors. The twin-motor configuration shown at MINExpo provides the optimum tractive effort in every duty cycle without torque interruption.
The Spicer Electrified e-Powershift transmission will be available for prototype testing by original equipment manufacturers (OEMs) by the end of this year.
“For more than half a century, Dana has been a trusted, leading provider of drive systems that deliver superior performance for mining vehicles,” said Jeroen Decleer, senior vice president, Off-Highway Drive and Motion Systems for Dana Incorporated. “The new e-Powershift transmission shows how we are leveraging our full portfolio of electrification technologies to provide mining OEMs with complete solutions that can help accelerate their journey to e-mobility.”
The Spicer Electrified e-Powershift transmission features Dana TM4 350-800 volt high voltage motors to improve efficiency, reduce overall package size and provide redundancy when needed. The motors have provided field-proven performance and durability for hundreds of thousands of hours in underground mining and other heavy-duty applications.
The transmission offers efficient shifting with a patented wet clutch and synchromesh, and it can be configured with a four-wheel-drive disconnect and PTO that eliminates the need for an additional motor and inverter. The system is an efficient turnkey solution, with transmission integration simplified through the use of a single APC transmission control unit. It uses proprietary software designed to optimize machine operation through multiple drive and PTO modes, including hill hold readiness and functional safety.
At MINExpo, the transmission is on display as part of a complete system that includes heavy-duty Spicer axles designed to withstand harsh mining environments while providing superior stopping power for reliability under full load conditions on all grades of functioning. The system also features Spicer driveshafts designed for longer life, minimal maintenance and lower operating costs.
