bauma 2022, one of the largest international trade shows for the construction and mining industries, is set to take place October 24-30, 2022. Held once every 3 years — alternating with CONEXPO-CON/AGG and IFPE in the U.S. and INTERMAT in Paris — the event highlights the latest components and equipment in construction and mining.
Like other industries, electrification of construction and mining equipment is becoming more prevalent. This is due not only to machine owners wanting to use lower emissions equipment but also governmental regulations. Equipment and component manufacturers have been working on electrified solutions for several years now, but the technology has finally gotten to the point at which it is viable in real-world applications.
Several OEMs have already introduced electric-powered machines to the market, and more prototypes continue to be unveiled. Currently, the majority of the battery-electric construction equipment available or under development is compact; this is due to the smaller battery size required and reduced charging times. But larger machine options, including hybrids, are in the works as well.
Mining has used electric drive for some time. And underground mining equipment has been powered by batteries for several years now as the elimination of emissions greatly benefits worker safety and reduces the need for expensive ventilation systems. However, these machines are much larger and many mine sites have their own electricity which has made the switch to electrification easier.
Electrification of construction equipment has its challenges due to the varying size and duty cycles of the equipment and the charging infrastructure needed. But as technology has evolved, electric-powered construction equipment is becoming a reality.
During a recent interview with Power & Motion, Kimmo Rauma, Vice President of Danfoss' Editron division, said electrification is now moving at a fast pace in construction equipment and other applications. He said bauma 2022 will have the largest collection of electric machines ever on display due to the significant growth taking place in electrification.
Several manufacturers have started to announce the electrification solutions they plan to show at bauma, including Danfoss which said in a pre-show press release that electrification will be among the key technology areas it showcases in conjunction with solutions for autonomy, digitalization and connectivity.
Briggs & Stratton Displaying New Battery Technology
In addition to its latest engines, Briggs & Statton will exhibit the newest battery solutions in its lineup. The company said in its pre-show press release the new battery technologies it plans to introduce at bauma will benefit those in the rental and construction industries.
Among the technologies on display will be the Vanguard Commercial Lithium-Ion Battery pack which is available in the North American and European markets. It is available in 5 and 10 kWh power ranges, and has already been integrated into various construction applications as well as those in the defense and agricultural industries.
In July, the company announced an expansion to its battery portfolio with the launch of its Vanguard 7 kWh Diecast Commercial Battery. This battery increases the amount of applications in which Briggs & Stratton's technology can be used.
HAWE Introduces New PowerBox for Electrification
HAWE Hydraulik has introduced a new PowerBox to aid electrification of mobile machines which will be displayed at bauma 2022. The PowerBox contains battery packs, a new Motor Pump Unit, a Power Distribution Unit, a charger and hydraulic components.

The PowerBox comes full charged and features a plug-in system for the battery packs to simplify runtime management said HAWE in its press release announcing the launch of the PowerBox. Once the batteries are fully discharged, they can be quickly swapped out for charged batteries which helps to minimize downtime for machine owners.
The new PowerBox has been put to use in loading cranes (see image at top of article illustrating use in this application) but can be used in a variety of other applications as well.
In addition to the new PowerBox, HAWE plans to exhibit its in-house developed battery packs designed to power off-highway equipment or driving a machine's working hydraulics. It will also show its ROVO robotic platform, an all-electric track-mounted drive system which can easily traverse off-highway work environments. HAWE will also show its technology for decentralized drives for hydraulic systems in electric-powered machines.
