Building and construction
Electrification that fits construction practice
A construction machine must be able to continue performing the requested work. We therefore investigate the load, the working day, and the available energy on-site before determining the drive and storage.
EPowerOne develops and integrates electric drive, demand-driven hydraulics, and control for existing equipment. For each machine, we determine which construction and components can be retained. Transport, hoisting, and auxiliary consumption may require different technical solutions.
We include the construction site in the design. How much construction power is available? When can it be charged? Which machines require power at the same time? An EPowerPack or other storage can be part of the chosen energy supply.
Concrete work: six Aichi aerial work platforms converted to 700 V DC and a Spierings AT598 with electric superstructure and its own EPowerPack. Within SSEB Green Heavy Lifting, we are further developing this experience for electric crane functions and energy recovery.
Customization for the machine and the construction site
Together with Van den Berg Staalbouw, we bring construction, manufacturing and energy technology together. A battery pack or drive unit must fit into the machine, remain accessible for maintenance and be able to handle the daily load. That is why we include frames, housings, mounts and weight distribution from the initial design.
We also look ahead to other machines on the construction site. Which charging facility can be shared? Which parts of an initial conversion are reusable? Where does a mobile energy supply fit? This helps to make an initial project part of a broader approach for the equipment.
Servo control and custom programming
A servo-controlled electric motor can adjust its operation to the required movement and load. We integrate the motor and drive and program the control for the specific application. In our Aichi retrofit, this is linked to the hydraulic work functions.
The focus is on controlled movement, sufficient power during work, and limiting unnecessary drive power during waiting times.
Hydraulic optimization
We bekijken pomp, druk, debiet, ventielen en de werkcyclus als één geheel. Samen met hydraulische partners werken we uit welke aanpassingen nodig zijn om de elektrische aandrijving goed te laten samenwerken met bestaande functies.
Door de energievraag bij de functie zelf te verbeteren, ontstaat een betere basis voor de keuze van motorvermogen, accucapaciteit en laadstrategie.
Own LFP battery packs
We have developed and built LFP battery packs in-house based on purchased cells and components. Our work includes assembly, housing, electrical connections, protection, battery management, and integration with the application.
We assess energy content, charge and discharge power, installation space, temperature, and maintenance together. We also use this experience to properly design the integration when choosing an existing battery pack.
Mobile storage, power distribution and control
With our own EPowerPack, we have designed and built a mobile energy system. This brings together storage, power electronics, connections, and control. Our experience with solar power, charging facilities, and power control connects this to the energy supply at a business location.
Engineering up to and including commissioning
We work from construction and schematic to assembly, cabling, programming, and testing. For frames, housings, and mechanical integration, we involve Van den Berg Staalbouw. We coordinate the involved disciplines into a single technical design.
