INTERMAT reveal for Hyundai’s 22tonne hybrid excavator

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.

Hybrid 220LC offers considerable fuel saving potential
236 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.

A motor-generator installed between the engine and hydraulic pumps takes care of electrical power generation and recovery.

“We can deliver a fuel saving of up to 25% on bulk earth moving, which can offset the higher purchase price in as little as 30 months,” said Van de Perre.
