Belgian manufacturer of concrete flooring equipment, B-mac, has launched a new electric walk behind finishing trowel, powered by Vanguard™. Designed to smooth and level concrete surfaces, the new product is a key tool in concrete work and, paired with Vanguard’s battery, delivers efficiency and reduced downtime.
The newest series of electric concrete trowels, designed specifically for the rental industry, includes three models with working diameters ranging from 60 to 90 cm. The 60 cm model is compact and well-suited for small areas, offering a 90-minute runtime. The 75 cm version balances power and size, making it ideal for medium projects with a runtime of up to 80 minutes. The largest option features a 90 cm width and a 60-minute runtime, perfect for large open spaces.
Typically, concrete finishing trowels are powered by petrol engines to avoid downtime, however, customer demand arose for an electric-powered machine suitable for indoor use and emission-sensitive areas. B-mac needed a robust battery solution that would deliver emission-free, continuous electric operation, whilst also meeting the rental industry’s requirements for complete standardisation capabilities including charging, communication protocols, safety, and interchangeability. The Vanguard 48V 1,5kWh* swappable battery pack (Si1.5) from Briggs & Stratton meets all these parameters.
The interchangeability of the Vanguard Si1.5 allows one battery to charge while the other is in use, enabling continuous operation. The high-power cells of the battery pack also allow for extremely fast charging currents - only 50 minutes to 80% and 75 minutes to 100% using Vanguard’s 1425W mobile charger.
The electric operation delivered by the Vanguard 48V 1,5kWh swappable battery pack ensures less noise and vibration, and reduced harshness for equipment operators and their working environment. The reduced noise level and zero emissions at point of use facilitates operation in more diverse work sites, especially indoors, when compared to petrol-driven machinery.
As well as the above, the Vanguard Si1.5 battery guarantees durability in the toughest conditions with its sturdy casing and built-in battery management system. Designed with a safety-first mentality, each Vanguard battery is equipped with a battery management system (BMS) which monitors the voltage, current, resistance and temperature while the pack is in use. In addition, the Si1.5 stands out for its excellent connectivity, thanks to the J1939 CAN-bus communication protocol, which allows the battery to communicate effectively with other components of equipment for seamless integration.
Paul Bramhall, Director of Electrification/Rental EMEA at Briggs & Stratton said, “We are proud to have supported B-mac in the development of this new product, delivering on all their requirements and those of the rental industry, ultimately bringing an exciting new electric product to the construction market. Our Vanguard 48V 1,5kWh swappable commercial battery pack delivers safety and durability for users, as well as easy interchangeability between equipment and charger for minimal downtime, making it perfectly suited to the rental market. As an added bonus, our competitive 8-year commercial limited warranty provides essential peace of mind.”
Willem Decramer, Managing Director of B-Mac, said, “Finding the right electrification partner was vital for product development, to ensure that our new battery powered concrete trowels would maintain our high-quality performance. The power solution delivered by Vanguard has answered every requirement and we are extremely pleased with our new electric product range.”
