Kalmar is building – and selling! – these massive electric reach stackers in China

This news is about heavy port and shipping equipment, not home energy systems, so it does not affect your house directly. Kalmar, a Swedish equipment maker, builds electric "reach stackers" — huge machines used at ports and shipping yards to lift and move cargo containers, with lifting capacity up to 45 tons. The company makes these at a plant in Shanghai and just announced four new orders from customers in Mongolia, Tianjin, Shanghai, and Hong Kong, its latest push into the Chinese market.

The bigger detail is technical: these four machines are the first to use Kalmar's new lithium-ion battery packs instead of the older lead-acid type. The new batteries hold more energy, handle heat better, and charge faster, which the company says makes electric reach stackers an even stronger alternative to diesel versions for lifting and moving shipping containers.

Kalmar is also touting the ERG450 model as its most sustainable reach stacker yet, saying it uses at least 50% recycled steel and has swapped out traditional iron counterweights for a new material made from unprocessed, naturally heavy substances, both aimed at cutting the carbon footprint of manufacturing.

None of this involves home appliances, heating systems, or rebate programs. It is simply a sign that electrification and battery improvements are spreading into industrial and shipping equipment, which has no direct bearing on decisions homeowners make about upgrading their own houses.
