When will we see battery driven floor grinders?

Published 19/12, 2022 at 16:27

There weren’t so many new products introduced at bauma this year but there were a number of new models for grinding, polishing and cleaning surfaces.

Every year we publish our special feature on new concrete floor grinding and polishing equipment in PDi 5. With the bauma show just a few weeks ago, one could expect that there would be more new developments on the market introduced at bauma. But in general, the flow of new products was quite low at this year’s show. But in this feature we are able to introduce some of the latest from manufacturers. With a big focus on battery power, one could expect to find some new battery driven floor grinders launched at bauma, but perhaps the industry is not ready for that yet with the current battery technology unable to provide that power.

 

News from Airtec

Swiss manufacturer Airtec introduced two new products. First out is the new diamond drum concrete shaver ‘Shave Master SM-320’. The new shaver is equipped with a switch box with an on/off button, emergency stop and a control for the supply voltage. It has a speed control for power forward and reverse and has a variable drive speed between 0-4m/min to 5m/min. It is equipped with a single level for drum engage quick lift. The cutting depth can be micro depth measured for fine tuning of the depth of the diamond drum. It is said to have a unique wheel transmission and drive for on spot U-turns. The hydrostatic drive unit is completely sealed and the machine has a full safety operating unit with a security switch. The shaver has a built in vacuum connection for a close to dust free operation.

The second development is the BS-270 floor grinder for the removal of coatings, glue and adhesives. It is also suitable for cleaning dirty surfaces, built up concrete, asphalt or wood panels. It has also been developed for abrading latex, mastics, sealers and adhesives as well as smoothing rough concrete surfaces and rain marks. Airtec states that it is ideal for levelling high spots on concrete floors. It also has a unique floating system for particularly difficult jobs. It is easy to transport thanks to its light weight and compactness. It is sturdy and has a heavy gauge steel construction. It is equipped with a vacuum cleaner port for dust free operations. The handle may be elevated and the machine has a detachable dust shroud for easy grinding of wall edges or vertical surfaces. The machine’s working width is 270mm and the speed is 1,500rpm and it weighs 57kg. As an option it can be equipped with speed regulation.

The BS-270 is equipped with the unique and patented Airtec ‘Flipair’ system. This system causes a suction effect during the grinding process due to the rotation of the tool plate. The suction effect generated significantly increases the air flow and at the same time the fine dust is directly captured from the diamond tools and the grinding surface. The increased flow orientates the dust exhaust air towards the industrial vacuum cleaner, prevents overheating of the diamond tools and at the same time reduces frictional heat. Thanks to the clean, dust free floor surface, the diamond tools produce a better sanding performance with a longer service life. The significantly increased exhaust air also prevents the dust particles from escaping sideways. The innovative and sustainable dust solution also ensures greatly improved air quality for the user and the surroundings. The Flipair assistance system is part of Airtec ‘Dust-Away’ technology line. BSs-270 is available with or without the Flipair system.

New surface products from Husqvarna

Husqvarna Construction has launched the first wave of its rebranded Blastrac and Diamatic surface preparation product range. Since 8 June, the fully integrated offering, including floor scrapers, scarifiers and floor grinders, is available to order in all key markets.

The acquisition of Blastrac was completed in January last year and it was late in 2021 that Husqvarna Construction publicly announced its intention to further consolidate brands in the surface preparation segment with a supporting campaign labelled, ‘The Orange Evolution2’. “We have showcased our rebranded product range at multiple trade shows, it has been very well received and we are really happy to announce that we are now ready to start delivering to our broad range of customers in the surface preparation industry,” says Stijn Verherstraeten, senior vice president Concrete Surfaces & Floors, Husqvarna Construction.

The additional offering has considerably enhanced the existing Husqvarna surface preparation portfolio by bringing advanced shot blasting, scraping and scarifying solutions to Husqvarna customers and partners. In turn, Blastrac customers and partners now have access to adjacent products such as compactors, concrete placement equipment, sawing and drilling equipment as well as demolition robots and a wide (digital) service offering. “We are extremely proud to provide our customers with what is most likely the best and broadest surface preparation range in the industry and all of this under one strong brand,” says Stijn Verherstraeten. With this first wave of rebranded Blastrac and Diamatic products, Husqvarna has further shaped and complemented its offering for floor grinding, scarifying and scraping.

At bauma 2022, Husqvarna Construction showcased some of the products that will be part of the second wave, targeted for introduction in spring 2023. This will include shot and steel blasting solutions and associated dust extractors. Steel shot blasting goes broader than just construction and is a cost effective and efficient solution for paint removal and surface remediation in applications such as windmills, ship decks and petrochemical storage vessels. Until 2023, these products will continue to be available under the Blastrac brand. Along with the extended surface preparation offering, Husqvarna Construction featured its new high capacity ride on grinder, BMG 1500. With a working width of 1,500mm, it has been designed for large scale grinding projects, where high performance and time efficiency is of the essence.
