“The road to zero emissions” is one of the key themes of bauma 2022 and many exhibitors will be showing brand new electric solutions at the fair, which is being held from October 24th to 30th in Munich.
Here is a glimpse at some of the new products expected at bauma 2022:
Reversible vibratory plate with battery
The APU3050e from Wacker Neuson uses the proven hydraulic adjustment system to change direction, just like in conventional models.
With a working width of 50 cm (20 in) and a centrifugal force of 30 kN, the machine is easy to control and has the lowest overall height of all reversible vibratory plates on the market, making it ideally suited for use in narrow trenches.
Zero-emission e-tandem rollers
Hamm AG will present eight models from the HD CompactLine series in their world premiere at bauma.
These units are powered by a maintenance-free lithium-ion battery with a capacity of around 23 kWh. In addition, the energy released by the traction and vibration motors during braking is used in recovery. The battery has enough capacity for an entire working day.
Also, the e-drive reduces noise emissions, making the e-tandem rollers suitable for all areas that require particularly quiet compaction. Because these settings also often require a low vibration load, Hamm AG is introducing an electric combination roller with oscillation in addition to e-vibration and oscillation rollers.
All-electric T7X track loader
The T7X, still in the concept phase, is the world’s first all-electric compact track loader.
Its manufacturer, Bobcat, will use bauma to continue gathering customer feedback from different segments, aiming to be able to better assess market opportunities for the machine in Europe, the Middle East and Africa.
The T7X boasts a mobile payload of just under 1,400 kg (3,086 lbs) and with its 62-kWh lithium-ion battery pack, the T7X can operate continuously for four hours.
In contrast to all other loaders worldwide, the new machine requires virtually no fluids. Bobcat has completely replaced the traditional hydraulic system with an electric drive system comprising electric cylinders and electric drive motors. The only liquid in the machine is about four liters of environmentally friendly coolant.
Electric-drive concrete mixer
Putzmeister envisions a future with all-electric concrete transport thanks to its iONTRON e-mixer.
The vehicle’s battery has a capacity of 350 kWh, which means that one battery charge is enough for five to six trips in urban areas—usually sufficient for an entire workday.
The mixer can recharge to full power overnight at a DC charging station.
Its virtually silent operation enables unrestricted use, even in locations with strict noise regulations—a significant competitive advantage when it comes to bids in metropolitan areas. Rising prices for fossil fuels also make the e-drive an economical alternative.
The E-Pack from Tadano is an electrohydraulic system with an integrated 32 kW electric motor providing low-noise and emission-free crane operation. This solution was presented at the last bauma in 2019. At that time, it was only available for a single crane vehicle. At the world’s leading trade fair this year, Tadano will show that, in the meantime, five of its AC cranes can be ordered with the E-Pack or existing cranes retrofitted with it.
The Japanese manufacturer will also offer a preview of the world’s first all-electric rough terrain crane. The machine is currently in an advanced development phase and is scheduled for market launch at the end of 2023. It will be able to drive to and from the job site and perform all lifting there using only the energy supplied by its batteries.
