Drive systems for hybrid and fully electric construction machinery
Environmentally friendly and powerful alternatives to diesel
Hybrid or electric work machines are a practical alternative to diesel-powered vehicles. With their dynamic and powerful driving behavior, hybrid and electric vehicles master the usual tasks with flying colors and they do this with long operating durations, flexible charging options, and minimum noise pollution.
With its wide service range from motors, converters, and control units to diagnostic and remote maintenance software, Baumüller offers future-looking hybrid and fully electric drive solutions for mobile machinery and commercial vehicles. Baumüller Anlagen-Systemtechnik is responsible for the design and engineering of the innovative drive concepts for the mobile machines and implements them from a single source.
Traction systems – flexibly adapted to the specific requirements
Baumüller offers two variants for traction systems: Depending on the demands placed on the machine’s autonomy on the building site and the required power input during operation, construction machinery can be equipped with a battery-powered drive or a diesel-electric hybrid system. The high starting torque increases driving comfort for the user. Recuperating braking energy allows for particularly economical operation.
There are also practical drive concepts for stationary applications with lower mobility requirements. Horizontal or vertical drilling machines, for example, can be operated from the building site power supply, with the integrated high-voltage battery covering any peak loads. Autonomy on the building site is ensured by a small power unit.

Mobile working hydraulics
In addition to traction systems, Baumüller also offers the electrification of auxiliary units. These include electrically driven hydraulic pumps for working hydraulics or electric power take-offs (ePTOs). Low-noise and low-emission driving and working are just two of the numerous advantages.
Auxiliary units – servo-hydraulics increase efficiency
The electrification of auxiliary units includes, for example, electrically driven hydraulic pumps for working hydraulics or electric power take-offs. The drives are space-optimized and can be integrated flexibly. Electric, decentralized auxiliary drives can efficiently regulate the pressure and flow rate through efficient servo-hydraulics, allowing a needs-specific pump output.

Efficient and robust drive systems
The installation space of the drives is optimized and they can be flexibly integrated into the design of the construction machine. Efficient servo-hydraulics enable electrical decentralized auxiliary drives to selectively switch the pressure and volume flow rate and control the demand-based pump output. The high starting torque increases driving comfort for the user. The recuperation of braking energy makes operation particularly economical. What you get, therefore, is an efficient and robust drive system, especially for mobile machines.

Proven technology for modern e-drive systems
Hybrid and fully electric construction machines have decisive advantages over machines with conventional hydraulic drive technology: higher energy efficiency, lower operating costs, and lower maintenance costs. In addition, hardly any fluids are used. No oil, no cooling water and, in the case of fully electric machines, no diesel. Less damage to the environment with a smoother and more accurate operational profile at the same time. A clear advantage for modern e-drive systems.
Fully electric and emission-free:
Construction machinery with battery-powered drive
Quiet and completely free of fine particulates: These are the main advantages of a fully electric or battery-run e-motor for construction machinery. The motors are run completely with rechargeable lithium-ion batteries, without any diesel engines.
Economical and powerful: Diesel-electric drives
Besides fully electric solutions, diesel-electric hybrid drives are the technology of choice when it comes to finding an economical, environmentally friendly alternative to equipping construction machinery with state-of-the-art technology.

The TRADUS tractor as a drive solution:
Engineered to be electric from the ground up for use in mobile machinery
Engineered to be electric from the ground up, TADUS Technologies developed the TADUS tractor together with Baumüller, a tractor that is perfect for use as a mobile work machine in the construction, forestry, and municipal sectors, among other things. Thanks to a frame structure fit for universal use, it allows the easy mounting of commercial vehicles for off-road and on-road use, such as wheel loaders or backhoe loaders, but also other vehicles such as street sweepers. The advantages of the tractor also come into their own in this vehicle category.
Smart drive solutions for drilling systems and rigs
Baumüller’s fully electric and hybrid drive solutions are also perfect for drilling systems, drilling rigs, and drilling machines. In such applications, the drilling drive can travel in a horizontal and vertical direction as well as a combination of both directions as a drilling line.
The drive concepts are developed precisely for all drilling positions as well as for a wide variety of materials to be drilled. The techniques of the drilling rigs range from earth drilling to application areas with rocks, such as tunnel drilling. In addition to horizontal drilling technology, drive concepts can be designed for all standard drilling methods.
Horizontal drilling machine: Fully automatic drilling operation and positioning traction
A significant reduction in noise and CO2 emissions was achieved by electrifying the horizontal drilling machine. Its turnkey drive solution was developed by Baumüller. The advantage of the solution is that the power supply can be easily secured through the construction power already available in most cases, and thanks to its being equipped with a high-voltage battery, it is still independent for positioning on the construction site.
Turnkey drive solutions for electrically operated drilling rigs
The drive technology developed by Baumüller has made a significant contribution to the success of Max Wild’s electrically operated drilling rig. By dispensing with environmentally hazardous hydraulic oil, the machines can also be used in ecologically sensitive areas, such as nature and water reserves. Coordinated drive components consisting of electric motors and b maXX converters from Baumüller take care of the feed of the carriage and drive the drill pipe. Baumüller’s turnkey drive solutions made it possible to perfectly combine environmental friendliness and high performance. The drilling rig has a nominal traction force of 250 tons and manages peak traction forces of up to 450 tons for short periods – and this for drilling over a distance of up to two kilometers.
Tunnel boring machine: Water-cooled synchronous motor replaces hydraulic motor
The tunnel boring machines in use today operate according to the pipe-jacking method. Pipes are driven into the ground using jacking force together with the drill head and laid without a trench.
Electric motors are easier to install in a drill head than hydraulic motors. There is also an environmental benefit to using electric motors, as they eliminate the potential for oil leaks into the ground. The challenge is to select a compact, energy-efficient motor with a high power density and a small installation space. The water-cooled synchronous motors of the DSC series from Baumüller meet these requirements.
