Hyundai used INTERMAT to show its 22tonne hybrid excavator – the 220LC-9. Designed and developed in-house with electric components from the company’s electronics division, the Hybrid 220LC uses an electric motor for its slew functions, enabling a smaller engine to be fitted.“This combination means we can use a four-cylinder 98kW engine in the hybrid compared to a six-cylinder 118kW engine in the conventional R220LC-9,” explained Hyundai product engineer Joachim Van de Perre.

Driveline technology continues to develop rapidly, with many manufacturers at this year’s Conexpo exhibition showing Tier 4 Final emissions solutions, along with a host of fuel saving transmissions and hydraulic systems, all aiming to reduce operating costs for the customer. However, while there was certainly a hybrid presence at the show, things haven’t perhaps moved forward as fast as many had expected.
Hyundai Heavy Industries is showcasing a hydraulic hybrid machine at bauma. The R220-LC Hi-POSS is a 22tonne-crawler excavator with a system that allows brake energy to be used for other functions. Hi-POSS stands for Hyundai intelligent power optimal sharing and energy saving. “This is the most novel thing we have,” said Hyundai product engineer Joachim Van de Perre. “With a conventional excavator, when you brake, the energy heats the hydraulic oil. Here we use the energy to perform another task with the ma
