Putzmeister introduces zero-emissions truck-mounted concrete pump range 

In response to the growing importance of environmental protection in construction, Putzmeister is introducing its iONTRON hybrid truck-mounted concrete pumps.

The range is available in 20 to 40m class sizes. The models comprise the 20m class BSF 24-4 and BSF 28-4, the 30m class BSF 36-4, as well as the 40m class BSF 42-5 and BSF 47-5.

Markus Frasch, Putzmeister’s head of product management, said the company’s patent-pending solution for integrating a plug-in hybrid in the hydraulic pump train is not just environmentally friendly, but also saves fuel, space and weight. There is virtually no limit to possible uses, as the 92kW electric motor easily covers typical applications in electric mode.

“The iONTRON makes it easy to work in an environmentally friendly manner. Simply unwind the cable, plug it in and utilise the power supply on the construction site. Switching from diesel drive to electric mode is also simple and can be done during operation. One can simply press a button to utilise the full power of the electric motor – from the support configuration right through to pumping concrete. Depending on the local electricity mix, this makes it possible to reduce emissions by up to 100%,” explained Frasch.

Environmental protection, he added, has become an important factor when tendering for construction contracts. However, investments also need to pay off for companies.

“Our iONTRON range has much to offer in this regard, including fuel savings and a delivery rate of up to 100m³/h. Putzmeister recommends that customers configure their iONTRON hybrid machine with an iLS core pump. These are particularly efficient. The improved intake behaviour achieved by removing bottlenecks in the concrete flow and the 25% lower fuel consumption, which is thanks to the innovative control system, are further advantages.”

CIFA launches new K42E electric concrete pump 

The K42E is equipped with a 30amp hour cell battery pack that powers two Rexroth electric motors. The first drives the hydraulic pump to move the boom and open the outriggers, while the second drives the pumping unit, in a closed circuit and at maximum capacity of 160m³/hour at 80bar.

The charging process is quick and easy, says the company, with the integrated battery charger compatible with the 220V system. The boom extends up to 42m and consists of five sections, with the last two made from carbon fibre.

“If the job requires higher performance than the batteries can provide, the new Energya pump can be connected directly to an electrical outlet on site,” explains Davide Cipolla, CIFA’s CEO. “The system will then cut out the batteries and power the electric motors directly from the power source. A 40m power cable is included.”

This, he adds, means that the pump continues to operate with the truck’s diesel engine switched off, thus eliminating emissions and noise. If there is no electrical supply on site, an emergency system allows end-users to connect the K42E to the truck’s power take-offs and use the engine to complete the work, then close the boom and outriggers.

“The aim is to eliminate CO2 and noise emissions throughout the supply chain, from transport to laying of the concrete, by expanding the possibilities of using high-performance vehicles in areas where noise pollution and CO2 emissions are prohibited,” adds Cipolla. “The special feature of the Energya K42E pump is that the battery allows it to always operate in full electric mode.”
