The Chinese government’s long-established strategy of using construction projects to boost domestic demand seems to have contributed to better-than-expected quarterly GDP results – and a huge spike in sales of construction machinery.China today reported economic growth of 6.4% for January to March of this year, which was the slowest quarterly figure for 27 years but ahead of analysts’ expectations of between 6.3% and 6.2%.Beijing has sought to head off the effects of weak global growth and the Chinese economy’s growing debt problems by sharply increased domestic investment this year. This has taken the form of tax cuts, infrastructure spending and total bank loans over the quarter of $865bn.Infrastructure spending is expected to grow 4.3% in 2019. This includes $120bn in railway ...

US plant maker Caterpillar has teamed with Dutch distributor Pon Equipment to develop a 26-ton electric excavator with a 300kWh battery pack. Caterpillar says it is the largest electric excavator ever built.The company already delivered a prototype to Veidekke, Norway’s largest contractor, which plans to use eight of them.The machine is a Caterpillar 323F Z-line model fitted with a 3.4 ton battery pack, which can store around five times as much energy as a medium-range Tesla 3. Veidekke says it can work for between five and seven hours before requiring a recharge. Erik Sollerud, chief executive of Pon Equipment, said:“Our mechanics have been rebuilding, adapting and testing for over a year together with specialists from Caterpillar. Among other things, the engine and d...

Inventors say digitising digger hydraulics would halve CO2 emissions

Revamping just one excavator would equal taking 18 diesel family cars off the road, say engineers. A group of Scottish inventors has received £11m to digitise the century-old model of hydraulics in heavy construction plant, which they believe will halve the greenhouse gas emissions excavators and other machines pump out now. They say the fuel efficiency gains are so stark that equipping a single excavator with their “Digital Displacement” technology would be equivalent to taking 18 diesel family cars off the road. The consortium, led by Edinburgh-based Artemis Intelligent Power, believes most of the energy produced by plant engines now is wasted as heat, and that implanting digital control in a machine’s hydraulics would radically improve efficiency. The 42-month r...
