Reliable performance in the world’s most extreme conditions
Wabtec’s optimized integrated drive systems. The power is inside.
GE Transportation, now a Wabtec company, introduced the first commercially viable electric drive system for large mining haul trucks in the early 1960’s.
Since then, the company has led the industry in the introduction of new technology to improve the truck’s cost per ton. These innovations have included the first solid-state control system, the first trolley assist technology for large haul trucks, the first AC electric drive system and the first demonstration of hybrid energy storage.
Wabtec offers the most complete line of AC electric drive systems in the industry ranging from 100 - 400 ton capacity. With service-proven transmission and electric components, the company is the recognized industry leader in electric drive systems.
10,000+ trucks equipped with
Wabtec optimized integrated drive systems
Wabtec's AC Electric Drive System consists of an alternator, control system, dynamic retarding assembly and motorized wheels.
Features & Benefits:
- Faster on the level and on grade
- Greater retarding range, including a continuous retarding capability to near zero speed

To help mines achieve success, we are committed to being the preferred global supplier of premium electric drive systems.
An Electric Future for Mine Haulage
Mining is not a choice – the way we mine is. As part of our electrification journey to make mining more sustainable, we have identified three areas of focus:
- The Electric Drive. These drive systems have been in operation for almost 65 years. Mines have traditionally used them because of their advantages over other systems, specifically, 1/3 the gearing, 85% reduction in bearings as well as durability and low touch times. Moving forward, they will be a must-have in zero emissions systems.
- Optimizing the drive system through electrification of cooling loads. All cooling of the drive systems has been done via a large impeller on the alternator or hydraulically driven blowers. With alternator driven cooling, whenever one of the truck’s systems needed additional cooling, the engine would be forced to increase RPMs to spin the alternator and provide more air to the system. Each system had the ability to demand increased engine speed for cooling. With the addition of optimized cooling, each major system has its own variable speed cooling blower—allowing for cooling “on demand”.? This optimization leads to great productivity, fuel savings and a longer product life.
- Implementing electrification on a truck. There are a number of ways to accomplish this, the simplest of which is with the addition of batteries to supplement the diesel engine. Benefits include lower emissions, lower fuel consumption and among others. The larger implementation would be to eliminate the engine altogether, which would require a larger battery and also a charging mechanism. This option would allow for zero emissions and lower noise pollution.
We need to make more sustainable choices in mining, and our path toward innovation is clear. With greater productivity, availability and lower fuel consumption, the future of mining is electric.
