Volvo Trucks & Putzmeister reveal battery-electric truck-mounted concrete pump
The Volvo FM Electric 8×4 Rigid Tag Tridem can be driven up to 50km and then pump up to 50m³ of concrete on a single charge. It is fitted with four batteries with a total capacity of 360kWh (250 kWh usable). These can be charged during the pumping of concrete with up to 250kW DC. The truck can also be charged using an AC connection with up to 43 kW.
The drive consists of two electric motors with a continuous output of 330kW, and the truck weighs a total of 32 tonnes. Meanwhile, the concrete pump has a reach of 42 meters, making it easy to conduct construction work in hard-to-reach places.
This new concrete pump is the latest addition to Volvo’s wider electric construction vehicles range, which includes transport trucks, cement mixers, concrete pumps, tippers, cranes and hook lifts. The electric truck was developed in partnership with Putzmeister and will soon be delivered to the Swedish construction firm Swerock for real-world use.
Christoph Fitz, Head of Sales at Volvo Trucks Germany, said: “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. […]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.”
Traditional concrete pump trucks use diesel engines which must remain in operation during pumping, leading to a large amount of emissions and noise. They are typically used to pump liquid concrete into hard-to-reach locations which can’t be easily accessed with wheelbarrows or chutes. The concrete is loaded into a hopper, then agitated using a spinning paddle. Using two hydraulic cylinders, the concrete is pulled from the hopper and then pushed into the delivery pipes. The vehicle operator is then able to control the delivery of the concrete to where it needs to go – which could be in building foundations, on upper floors, or behind buildings.
