Based on a capable Volvo FM Electric 8×4 chassis, Putzmeister revealed one of the world’s largest all electric concrete pump trucks at the bauma equipment expo in Munich, Germany this week. The zero-emission concrete pumper can up to 50 km and pump approximately 50 cubic meters of concrete on a single charge.
50 km (a little over 30 miles) and 50 cubic meters (about 65 cubic yards) may not seem like impressive numbers, but consider this: a single cubic yard of concrete weighs a little over 4,000 lbs. (2 tons). A bit of simple math later, and you’ve got a quiet, vibration-free machine blasting (65 cu. yds ×4,100 lbs./yd = 266,500 lbs.) of construction material nearly 140 feet (42 meters) in the air.
That’s over 130 tons of construction material moved a really long way, and that’s (of course) without the use of diesel or gas.
“Volvo Trucks is the innovator when it comes to new technologies in combination with electric trucks. After presenting electric concrete mixers and heavy applications for mining, we are proud to show yet another world-class innovation for the construction segment here at bauma,” says Christoph Fitz, Head of Sales at Volvo Trucks in Germany. “With this electric pump truck, customers can have a zero-exhaust emission solution, low-noise operation and an efficient process thanks to the work-while-charging capacity.”
The Volvo FM Electric-based concrete pump is motivated by a pair of electric motors developing a continuous 330 kW (442 hp) of output through the company’s proprietary I-Shift gearbox. The truck’s four battery packs add up to 360 kWh of capacity, which can DC fast charge at speeds up to 250 kW or operate continuously (pumping even more material) with grid power or PU500 remote power connection.
Electrek’s Take
There will surely be a few nay-sayers who’ll try to cite the relatively short-sounding range of trucks like this, or the 100-ton Tadano mobile electric crane, but the range is typically more than enough to operate in urban environments and motivate the asset across even the largest job sites. Additionally, the ability to plug in to grid power and operate 24/7 makes all of that quieter, safer, cleaner … and moot.
