Wacker Neuson ‘EZ17e’ zero emission excavator in breaking applicationPublished 8/7 at 18:37
A battery powered zero tail EZ17e mini excavator, equipped with a hydraulic breaker, has been seen to be an ideal solution for indoor demolition work, as it can be used in environments where emissions have to be kept to a minimum, such as fund in urban areas.
For many prospective users, the first question when it comes to battery powered equipment is how long is it possible to work with one fully charged battery. Wacker Neuson’s latest development is able to work a whole workday without intermittent charging, as the EZ17e mini excavator has an integrated lithium ion battery which can support a full shift independently from a power source. Intermittent charging can easily prolong the autonomy and in case of stationary applications, the machine can even be charged during working. The EZ17e supports a broad variety of hydraulic attachments including a hydraulic breaker that provides both high productivity and energy efficiency and is designed for maximum durability.
Intelligent battery management
At all times the operator can see the current charge level of the battery and the remaining time the machine can continue to work as based on the power demand of the current operation, with the time left calculated and continuously shown in the display. A full charge can be achieved at a household outlet (110V to 230V) or by quick charging with high voltage current (415V) in only four hours. High quality lithium ion battery technology has been in use by Wacker Neuson for several years and has proved to be especially durable. It ensures that all hydraulic functions have the performance of a conventional model of the same class. Thus, the excavator can work with a hydraulic breaker without any limitations.
“With the EZ17e, we have implemented a zero tail concept with generous performance dimensions. With the efficient, intuitive and emission free excavator, we satisfy the high standards of professionals who work in particularly confined space conditions, as is usual in interior demolition, for example,” says Stefan Bogner, managing director of Wacker Neuson Linz GmbH, the research and development centre for excavators within the Wacker Neuson Group. The model has also been designed to deliver easy handling, minimised maintenance and service costs as well as lower energy costs in operation. Furthermore the CO2 emissions of the zero emission products have been certified by TÜV Austria, with 81% of CO2 emissions of the EZ17e being able to be saved over the entire product lifetime, including battery production and energy generation (based on an EU mix), compared to the conventional product in the same class, the model ‘EZ17’.
Flexible in application, easy to operate
The new mini excavator is a zero tail model without rear overhang. This makes it the ideal choice for demolition work in confined spaces and indoor projects. This is precisely the type of environment where contractors need powerful, compact machines that can be operated without producing any emissions. An intuitive operating concept makes it easy for the operator to keep all functions within view. The excavator is equipped with an intuitive ‘jog dial system’, with all important information, for example the charge level of the battery, being clearly shown on the full colour display.
Already a reality
The Wacker Neuson zero emission series currently includes three battery powered rammers and three battery powered vibratory plates, a dual power mini excavator that can be operated with an electro hydraulic drive unit instead of the diesel engine, an electric mini excavator, an electric wheel loader, electric track and wheel dumpers and an internal vibrator system for concrete consolidation. With this wide ranging portfolio, a typical inner city construction site can be operated free from local emissions and at low noise levels.
