For a variety of reasons，The motor is useful for zero emission compression.、Carry、Transport and lifting，Other new products are kept secret before the exhibition.，Zero emission operation is one of the main trends in the construction machinery industry.。This is bauma Expected first launch of a new product。The world's leading construction machinery、The trade fair for construction materials and mining machinery, as well as construction vehicles and equipment, will be held at the Munich show site from October 24 to 30.。

In order to reduce greenhouse gas emissions to meet climate protection goals,，More and more construction machinery and vehicles are being developed with electric drive.。Other advantages are also driving the trend.。For example，The motor is very quiet，Therefore, it is suitable for use in low noise areas.，For example, near a hospital or at a city construction site。They also protect the operator and the environment from direct exhaust emissions.，Many workflows can be performed even in poorly ventilated areas。Another benefit is that the motor is considered to be low maintenance and efficient，This means that they ensure low operating and energy costs。So，“The road to zero emissions”Also this yearbaumaOne of the key topics.，It goes without saying.。

Reversible vibrating plate with battery

These include the first direct-drive, battery-powered, reversible vibrating plate。The manufacturer, Wick Northam APU3050e Use a proven hydraulic adjustment system to change direction，Just like in the legacy model。The working width of the machine is 50 cm，The centrifugal force is 30 kN，Easy to control，And has the lowest overall height of any reversible vibration plate on the market，Ideal for use in narrow trenches。

Use e-tandem Zero discharge compaction realized by road roller

Future，As long as zero-emission compaction on a larger scale is required，An electric tandem roller can be the solution.。

Hamm AG Will be in bauma Show in the Global Launch HD CompactLine Eight models of the series。They have a capacity of about 23. kWh Powered by a maintenance-free lithium-ion battery。In addition，The energy released by the traction and vibration motors during braking is used for recovery。The battery has enough capacity for one working day.。e-drive The noise emission is also significantly reduced，Make e-tandem Rollers are suitable for all areas where particularly quiet compaction is required。Low vibration loads are also typically required due to these settings，Therefore, compaction experts, in addition to electric vibratory and vibratory rollers,，An electric combined roller with vibration function is also introduced.。

All-electric concept for compact crawler loader

T7X Still at the conceptual stage，It is the world's first all-electric compact crawler loader.。Its manufacturer Bobcat Will be used bauma Continue to collect customer feedback from different market segments。The aim is to be able to better evaluate the machine in Europe.、Market opportunities in the Middle East and Africa。With its 62 kWh lithium-ion battery pack，T7X It can run for four hours.。It has a mobile payload of less than 1,400 kilos。Compared to all other loaders worldwide，The new machine requires almost no fluid.：Bobcat has completely replaced the traditional hydraulic system with an electric drive system consisting of an electric cylinder and an electric motor.。The only fluid in the machine is about four liters of environmentally friendly coolant.。

All-electric drive concrete mixer

With the help of iONTRON Electric Mixer，Putzmeister The future of all-electric concrete transportation is prospected.。The vehicle has a battery capacity of 350 kWh，That means one battery charge is enough for five or six trips in urban areas.——Usually enough for a full working day。If more trips are planned，The vehicle can simply be charged。The mixer can be charged to full power overnight at a DC charging station。Even where there are strict noise laws.，Its virtually silent operation can also be used without restriction——This has a significant competitive advantage in bidding in metropolitan areas.。The rise in fossil fuel prices has also made electric vehicles an economical alternative.。

Electro-hydraulic lifting

Tadano Yes E-Pack Is an electro-hydraulic system，With an integrated 32 kW Motor，Provides low noise and emission-free crane operation。The solution was in the last session of 2019. bauma Appear on。At that time，It only applies to a single crane.。At the world's leading trade fair this year，Tadano will display five of them. AC Cranes can be ordered E-Pack Or an existing crane to which it has been modified。

The Japanese manufacturer will also offer a preview of the world's first all-electric rough terrain crane.。The machine is currently in advanced development，It is planned to be launched at the end of 2023.。It will be able to travel to and from the job site and perform all lifting operations using only the energy provided by its batteries。

Other exhibitors have announced new electronic machines.，But hope to waitbauma“Let the cat out”。These include Kramer-Werke GmbH 5055e Successor models of all-wheel drive electric wheel loaders。In addition，The company promises a new electric telescopic loader.——No further details were given.。This is another reason why a visit to the Munich exhibition grounds in October is well worth your time.。
