Electric Actuaor

Excess Engineering has developed an eco-friendly electric actuator that replaces heavy-duty hydraulic systems, providing a highly efficient all-electric system to push, pull, and lift. The electric system offers a hydraulic-free option with improved energy efficiency, improved precision and control and remote monitoring of load, operation, maintenance, and health. Its size is comparable to existing hydraulic systems, which eliminates the need for significant modifications to the system's structure.

Problem we are solving
The primary objective of our project is to address a critical bottleneck in the industries’ shift toward electrification: The inefficiency of hydraulic systems particularly in electrically powered machinery. Despite advancements in electric motor and battery technology, the persistence of traditional hydraulic systems significantly undermines overall efficiency. In an electric-powered machine, the role of the hydraulic system becomes crucial because it's responsible for nearly two-thirds of the energy losses.
At present solutions to lift, pull and push with strong force (above 10 tons) are hydraulic systems, where at high pressure oil is used to control the machinery. This has several challenges: 1. There is a significant loss in efficiency; 2. Control of the machinery is not immediate, as control goes through oil pressure, that is a challenge in some applications requiring precision. 3. There are many moving parts and oil flows that require maintenance. 4. Need for several hundred liters of oil in the hydraulic system, that also needs maintenance and replacement.
Our project aims to replace these outdated hydraulic systems with advanced electromechanical solutions, specifically designed for heavy-duty applications such as heavy machinery, marine, subsea and offshore. Our innovative electric actuator is capable of handling heavy loads up to 100 tons, with a stroke up to 3 meters. These electric actuators excel in handling heavy loads while maintaining a compact design comparable in size to existing hydraulic systems.
Due to the unique features of our solution, it can replace hydraulic systems in heavy-duty applications, resulting in energy savings and substantial reductions in GHG emissions. Additionally, it prevents hydraulic oil leakage, which is a significant threat to marine/aquaculture environments.

Sustainable Impact on Blue Ecconomy
Our system combines three elements, that put together are unique:
- An all-electric system, hydraulic-free alternative for heavy-duty applications
- High push, pull and lift capacity with a long stroke (up to 3 m) in a small envelope
- Highly efficient with improved precision
