Innovation and sustainability are Kramer's key values and the main driving factors for the continual design and development of new machines. For many years, we have been searching for alternative forms of energy and drive technology to achieve our goal of developing machines which are sustainable and environmentally friendly yet are still high-performance. The topic of electromobility has also been playing a major role within the construction industry for a number of years. Electric construction machines are no longer a rare occurrence on building sites, but many of them are powered by cables. The challenge we set ourselves here at Kramer was first and foremost to develop resource-efficient, mobile and compact construction machinery. The objective was and still is to include the same performance range in electrically operated vehicles as achieved by our diesel vehicles. The criteria we set during development have certainly been met by our first fully electric 5055e wheel loader.
