2-Wheel-Loader
A new type of mobile work machines for agricultural and construction machinery
Movability. 40% Energy Savings. Low Costs.
Advantages:
- Energy savings of up to 40% compared to standard electric wheel loaders thanks to mass reduction
- Lower vehicle weight: Ratio of payload to empty weight approx. 1:1
- More agile movements thanks to the Segway® movement principle: we can turn on the spot (also inside of buildings with minimal space)
- Easy to transport thanks to low weight and short design
- Can be used as a tool carrier working with various attachments

Lightweight Construction. Easy To Transport.
The Concept
Even when loaded, our 2-wheel-loader is very short because the load can be placed above the main axle. This allows the counterweight to be retracted.
When the 2-Wheel-Loader picks up the load, the counterweight must be moved to the rear.
The width of our first prototype will be 1.2 meters. This equals the width of a pallet. The prototype weighs 1.6 tons and can transport a load of 1.6 tons.
How do we maintain stability and get traction?
So far, stability has been created by having enough mass and being oversized. We want to develop an electronic control system that moves the counterweight so that the center of gravity is always above the main axle.
State of the art: Depending on the use case, the center of gravity is between the two axles. The axle load is distributed as shown, which means that two heavy-duty axles are required.
2-Wheel-Loader: The center of gravity is always over the main axle, where the entire axle load is permanently located and offers full traction. The auxiliary wheel on the counterweight only has a small load, so there is a buffer against falling over.
How to reduce energy consumption?
I. Reduce power losses of electric driveline components
- Only one heavy-duty axle
- 2 electric wheel motors plus simple planetary transmissions
II. Lighter machines perform the same amount of work
- Faster movements (on the spot turns)
- Less vehicle weight: ratio of payload and empty weight can reach 1:1
How to cut costs?
I. Lightweight construction
- No over-dimensioning, only as much material as required
- No expensive articulated steering: we steer via speed and directions of rotation of the wheel hub motors
- Only one heavy-duty axle
- Elimination of components
II. No driver's cabin
- Automation and assistance functions are required depending on the model
- New work processes are supported by the maneuverability and new design
How do we create the same breakaway force?
The design allows a smaller 'reach' to be created, which generates more force at the cutting edge of the shovel. Increased vertical break-off force is given by the short lever arm between the front wheels and the shovel. This is to compensate for the lower weight of the 2-wheel-loader.
Easier to transport? Sure, car trailer instead of a truck.
I. Lightweight construction
- Less fuel consumption when transporting the 2-Wheel-Loader from job site to job site because less weight is transported
- Short design allows the use of a transporter or car trailer
II. Use of only one axle
- With mechanical decoupling of the drive train and suitable tires, direct transport is conceivable with a drawbar.
Use-Cases
Material Handling
Monotonous work processes such as loading asphalt mixing plants or gravel pits can be ideally automated with the concept. Due to its advantages, this concept favors such an automation. Work processes will have to change in the future because of the shortage of skilled workers.
Farming
Farming with a tool carrier, which takes over the work of a farm loader. Especially in barns with little space, it is an advantage to be able to turn on the spot. The concept maintains ceiling loads and protects the subsurface.
Construction Robot
The low empty weight, the short design and the maneuverability allow the concept to be ideal for indoor use. High masses can be transported while the overall weight remains relatively low. In this way, ceiling loads can be maintained, while the short design also enables the use of elevators.
Did you know?
The largest German construction companies see great potential in our concept. According to them, there can both be used, remote controlled applications and autonomous operating applications.
