Kramer has announced it is launching a fully electric wheel loader. The 5055e is ideal for working inside buildings, in inner-city construction sites or in tunnels, where it is important to keep emissions as low as possible.
Operators and the environment are protected thanks not only to the zero emissions technology but also thanks to extremely low noise levels a fact that may interest municipalities and holiday regions, where residents and holiday guests will not have to suffer the effects of noise and exhaust emissions.
Kramer claims that despite its higher initial price, costs will quickly be recouped by lower maintenance costs. Usual maintenance intervals still apply to ensure that the machine continues to work reliably and economically, but as maintenance of an engine is not required, inspection of the machine is correspondingly shorter and hence cheaper. In addition, there is a price advantage of electricity compared with diesel fuel.
In the size class of 0.55m³ bucket capacity, Kramer’s 5055e wheel loader launches the first fully electric machine on the market. The performance parameters, off-road capability and ease of operation are equal to the conventional model. Thanks to the stack payload of 1,750kg, the wheel loader is versatile in its application; for example, transport of stone palettes is possible without any problems.
Kramer emphasizes the coordination of parts and components, to allow precise operation. To achieve this, two electric motors are used: one for operating the hydraulics and one for the drive. Depending on the application, power is automatically provided by the respective motor, which helps minimize energy consumption.
The electric motor is powered using reliable lead-acid accumulators or lead-fleece accumulators. The battery charger is integrated with the lead-fleece accumulators and charging is very easy, as it can be accomplished via a standard power socket (230V). Depending on the application and utilization of the wheel loader, a single charge lasts up to five hours of operation. The charging time of the machine is between four and eight hours depending on the battery option chosen.
“We are pleased that we can offer our customers an emission-free and environmentally friendly machine. We are certain that this product will make an important contribution to preserving resources and increasing the efficiency of our customers,” said Karl Friedrich Hauri, managing director at Kramer.
