The PC138E-11's electric motor has an output of 72.5 kilowatts. Thanks to a lithium-ion battery with a capacity of 225.6 kilowatt hours and a cooling system for the battery and electrical components, long operating times are possible with this short-tail excavator, Komatsu writes in its press release. The manufacturer does not go into further detail.

But it does point out other advantages. The machine is 7,970 mm long, 2,490 mm wide and 3,005 mm high. According to Komatsu, the machine's compact dimensions allow it to be used on many different construction sites. For example, in urban areas where space is limited.
More quiet and comfortable work
In addition, the use of machines without combustion engines naturally reduces construction noise, which also increases safety on the construction site. Komatsu says that this will allow the operator to easily communicate with people outside the machine while it is running, which makes the work more safe and precise. In addition, the machine vibrates less and the air around and inside it does not overheat excessively, resulting in a more comfortable working environment.
Like other Komatsu machines, the PC138E-11 is equipped with Smart Construction 3D Machine Guidance. This is a display system that allows a 2D or 3D display to be set up and adapted to each customer's machine configuration and operating conditions.

Komatsu plans to rent the electric excavator "to different customers with different applications and different power supplies in regions where a market for electrified machines is expected to develop in the future". The company's goal is to build a market for electric construction equipment and achieve CO2 neutrality by 2050. (mfo)
