With global warming and the energy crisis becoming more serious, the emission regulations
for construction machinery (CM) are increasingly strict. The pure electric drive system is an …

Construction machinery, especially hydraulic excavators, plays an important role in building
and other industries. However, they often consume a lot of energy and emit large amounts of …

This paper proposes a new hydraulic excavator boom driving system using novel
asymmetric pump to reduce energy consumption. Due to large throttling loss and …

When the hydraulic excavator boom drops, the gravitational potential energy accumulated
during the lifting process is converted into heat energy and dissipated through the throttling …

Though the current wave of electric vehicles is transforming the on-road passenger and
commercial vehicle fleets, similar attempts in the off-road equipment sector appear to be …

Fuel cell hybrid excavators (FCHEs) are an attractive long-term future option. This paper
presents an approach for the energy management and economic analysis for an excavator …

The push for a more sustainable logistics industry has been driving heavy machinery
manufacturers to develop electric construction machinery (ECM). To improve energy …

Multi-joint heavy-duty manipulators, such as working devices of hydraulic excavators, are
mostly driven by hydraulic cylinders. Poor energy efficiency of the hydraulic system results in …

Hybrid Construction Machinery (HCM), known as an effective and crucial solution for the
issues of environment pollution and energy shortage, has aroused increasing attention from …

Construction machines are heavy-duty equipment and a major contributor to the
environmental pollution. By using only electric motors instead of an internal combustion …
