Despite challenges like battery limitations and the need for new skills, the benefits of zero-emission, more efficient, and reliable electric construction equipment are driving a growing market and a more sustainable future for the sector. While smaller, compact machines are already leading the shift, larger equipment and infrastructure, such as charging strategies, are current areas of development.
Hybrid and electric powered machinery generate less noise and vibration, leading to a safer, quieter, and more comfortable work environment, especially on construction sites located in city centres and in enclosed spaces.
Electric motors are more energy-efficient than internal combustion engines, translating to higher performance. They also offer greater control and the ability to use energy recovery systems, like converting kinetic energy from braking into power.
The initial phase of electrification focused on smaller equipment such as mini excavators, wheel loaders, compactors, and telehandlers, with their lower power demand making a full day's operation feasible with current lithium-ion battery technology.
Now, many of our leading OEMs are concentrating on bringing heavier electric powered equipment to the market, and while battery-electric technology is a primary focus, some manufacturers are also exploring other alternatives like hydrogen and biofuels to achieve zero-emission operations.
Although electric construction equipment generally has a higher initial purchase price than diesel alternatives, this is offset by lower operating costs over time.
Clearly, electrification in the industry is set to continue accelerating, particularly as battery technology improves and costs decrease. Manufacturers are developing high-power-density batteries and more efficient electric motors specifically for off-highway applications.
While smaller equipment leads the way, as we mentioned, there is also an increasing focus on a combination of hybrid, battery-electric, and alternative fuel technologies for heavy-duty applications.
