As well as these, there is no shortage of even newer products arriving in the same field, which are now covered in our special feature.
New ‘Scoots’ from Au Tour du Beton
Au Tour du Beton’s bush hammering Scoot makes it possible to transform a variable speed grinder into a bush hammering machine through installing the system on the grinder and screwing in the bush plate. The system is easy to install on an Ø180mm variable speed grinder, and is equipped with a front and back handle, with wheels providing stability, and the shroud having an outlet for connecting to a vacuum cleaner. The Scoot enables the use of Ø120mm or 155mm bush hammer plates depending on the desired finish, with Au Tour du Beton offering several models of hand held bush hammer plates with a lifetime guarantee. Similarly, the stand-up Scoot enables the user to turn a variable speed grinder into a bush hammering machine for work where the user wants to stand upright through installing the system on the grinder and screwing in the plate. Lastly, the Scoot can turn a standard angle grinder or polisher into a planer, coming in three formats that fit most grinders. The user needs to set the two screws provided onto the grinder and then clip them into the two ball joints located at the front of the Scoot.
New technology from Ashine
Ashine’s R&D team has been working on new technology in both metal and resin bonds in the past year as well as new production facilities. Ashine’s ‘W-Metals’ diamond technology cuts well on hard to extra hard floors, whilst its new resin bond technology has seen Ashine develop ‘V8’ pads which meet the industry’s requirements for gloss and clarity. With the newly designed ‘Quick-Start’ segments, V8 pads are able to make the diamonds work faster and avoid deep irregular scratches at the start. With strong growth in the past five years, Ashine has also built its own 10,000m2 production facility located close to its existing operation.
Several new Products from Blastrac
At bauma, Blastrac launched many new products including a new large scale ride on floor grinder, BMG-2200, which is designed for large horizontal surfaces. With two drive wheels fitted to the front and a swivel castor to the back, this makes the machine manoeuvrable both on and off jobsites. The operator sits on a seat with arm rests on both sides, along with joysticks, push buttons and a touch screen. The three powerful BMG-780PRO grinding heads produces maximum coverage and effective distribution of grinding pressure on each individual head, meaning each grinding head can be operated individually. The machine comes as standard with variable grinding speed, rotation direction and an independent suspension system.
The BMG-2200 also has variable grinding pressure, being designed with an integrated powerful dust collecting system with HEPA 14 filters, making the BMG-2200 virtually dust free according to OSHA regulations. This heavy duty dust collection system is equipped with an automatic pulse filter cleaning system, ‘Longopac’ system, and is provided as standard with a pre-separator.
The new multitask vehicle BMR-75D features an enhanced trouble free hydraulic drive system, offering better productivity when cleaning and preparing concrete or steel surfaces. As the BMR-75D can fit several attachments, it gives the user greater flexibility to satisfy the needs of the job in hand, whether it is shot blasting or scarifying. The BMR-75D is also ideal for ship decks, parking garages, bridges, roads and warehouse floors. All Blastrac cyclone technology surface cleaning machines are engineered to deep clean outdoor surfaces efficiently and in an environmentally friendly way. A multi patented cleaning and recovery head cleans and removes build up with no damage to the surface. The cyclone cleaning head provides high velocity air movement for recovery of waste and water, with no runoff or spillage and no need for an external vacuum system.
Blastrac has also developed a new range of single phase dust collectors. With this new line Blastrac aims to meet customer expectations from an industrial dust collector, professional end user perspective. Equipped with an M-class or H-class certified Longopac bagging system, for small or big jobsites, the dust collector is designed to meet all needs. The new line aims to offer a complete range of small, powerful and high quality dust collectors, all coming equipped with a safe bagging system that protects the health of the operators and saves time on jobsites (Longopac system).
‘Start & Grind’ extended with HTC 510
In January 2019, HTC launched an entirely new line of floor grinders and dust extractors with a focus on user friendliness and ergonomics. This ‘Start & Grind’ line is now being complemented with a new grinder – the HTC 510 – bringing the total line up to four grinders and four dust extractors. The new HTC 510 is a powerful planetary grinder with three counter rotating grinding heads, making this a versatile grinder suitable for many different applications. It can be used for everything from stripping floors to grinding and polishing concrete, natural stone and wood. The grinder is available both in a single phase and three phase model, from 2.2kW up to 4.0kW, featuring a grinding width of 515mm. A major advantage of the HTC 510 is the machine's grinding head, which is hermetically sealed, making it entirely dust proof. This provides unparalleled protection from dust and moisture, and significantly increases the service life of the enclosed components. Just as with the other grinders in the line, the HTC 510 chassis can be easily detached (and folded up) from the motor prior to transport. It is effectively a robust, strong, versatile and ergonomic entry level machine for professional users who want to quickly and efficiently grind small to medium sized areas.
Floor stripper from Janser
Janser’s new ‘Junior’ ride on model weighs 420kg and uses an in house developed drive design which allows the front plate and tools to be manually positioned during operation. Thanks to its adjustable angle the blade can be set to a flatter or steeper angle under the floor covering. The forward leaning construction puts the centre of gravity under the plate itself. At the core of the Junior is the construction of the motor and hydraulic drive with which the front tool can also be controlled. If the base plate is lowered to its maximum, the blade can reach further under the floor covering which is especially suited for the removal of elastic coverings. The Junior’s base angle and inclination angle, as well as the positioning of the front plate, can be adjusted via a lever near the seat during operation.
With its slim measurements of 1,300mm x 600mm x 1,000mm, the Junior can be transported in smaller vehicles. Operation is facilitated via a power cable which is kept at a safe distance to the wheels or kept above the machine in narrow spaces with the help of a guide rail. The machine features a reverse warning system and a seat switch which turns the machine off automatically as soon as the operator leaves the seat. Hearing protection is not necessary when using the machine as the motor and the hydraulic system operate silently.
