More power and performance

The Wacker Neuson Group is a global manufacturer of light and compact construction equipment that has grown from humble beginnings in a Dresden blacksmith shop into an international group of companies. Like all of their products, the new ET42 4-ton compact tracked excavator was developed to meet real-world requirements based on extensive research and voice-of-the-customer inputs.

North American customers in particular wanted operator comfort and improved visibility along with more power and performance in a smaller package that meets U.S. EPA Tier 4 Final emission standards. Operator comfort is delivered by a range of features including standard air-conditioning, an air cushioned seat with adjustable arm rests and an easy-to-use load sensing joystick control system. Visibility is enhanced with a newly designed low-proﬁle hood and expanded side window glass, which allows the operator to see the front of both tracks.

Power and performance are delivered by the Perkins® 403J-E17T 48 hp diesel, water-cooled, 3-cylinder turbo engine Wacker Neuson chose for the ET42.

“With the combination of the high-powered, smaller diesel engine and an electronic-controlled hydraulic pump,” Martin Spandl, technical project lead at Wacker Neuson explains. “We can run the machine more dynamically and can run the maximum available torque of the engine. The pump system and the engine system work together in a completely new way at this power size.”

The ET42 is testament to Wacker Neuson’s collaboration with both Perkins and its customer base, demonstrating the company’s dedication to listen to the wants and needs of its customers and work together with others to meet those demands.
