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.
Dynaset ‘SCU’ surface cleaning unit
Dynaset is getting in to the surface cleaning sector by launching the Dynaset SCU surface cleaning unit. The SCU attachment cleans parking garages and other large areas with flat surfaces. The unit washes the surface with high pressure water and the vacuum collects the dirty water for recycling. The unit leaves a clean and dry surface behind without making any mess to the surroundings. Users are said to able to clean up to 60,000m2 per day. The unit is safe to use due to a splash cover and is able to easily can clean around cars, windows or any objects without any fear of dirtying or damaging them. The unit’s vacuum can collect over 90% of the washing water. Additionally, it is possible to use the unit to collect, for example, rain water from surfaces. The unit makes surface cleaning extremely efficient, with optimal washing results even at 5km/h. The attachment is said to be ideal for cleaning parking garages, car parks, terminal areas, large factory floors, paved market areas, boulevards, logistic areas, paths and pavements, mall surroundings, storage areas, large indoor areas, tradeshow areas, etc.
The unit has a maximum operating speed of 5km/h. The water pump’s output is 50l/min, maximum water pressure is 220bar and the working width of the unit is 150cm (whilst weighing in at 720kg).
