Applications:
The Revolution Battery replaced a diesel generator on hoist operations, saving £550 per week in fuel and rental costs, reducing CO₂ emissions by 708kg per week, and capturing 111kWh of regenerative energy that would otherwise have been wasted.
Construction hoists are vital for vertical transport on building sites, but they pose unique energy challenges. Their motors often use Direct on Line (DOL) starting, which is simple and cost-effective but causes large inrush currents. While manageable on grid power, these spikes can lead to excessive diesel consumption when powered by generators.
The challenge of powering construction hoists is compounded by several factors:
Brogan Group partnered with Falcon Power Generation and Dumarey Green Power to trial the Revolution Battery system on a DOL start hoist on their test tower. The goal was to reduce fuel use, capture regenerative energy, and prove battery viability for hoist operations.
The Revolution Battery system was installed to address several key challenges in hoist operations. It provides the high start-up power spikes required by the two 9kW motors, ensuring smoother and more efficient operation. Additionally, it captures the energy generated during the downward movement of the hoist and stores it for reuse in future cycles.
Based on the results of testing, a theoretical duty cycle was designed to highlight possible results from real-world deployment:
The diesel generator was completely removed and replaced with a 16A mains supply and the Revolution Battery. The system’s ability to both deliver high peak power and absorb regenerative energy makes it uniquely suited to hoist applications.
The Revolution Battery trial delivered compelling results:
The Revolution Battery proved that hoist operations can be cleaner, smarter, cheaper and more efficient. The successful test opens the door for wider adoption of battery systems in construction hoists, especially where grid access is limited or diesel use is high.
“The Revolution Battery has shown us a smarter way to power hoists. It’s efficient, compact, and makes use of energy we’d otherwise waste.” – Brogan Group
