Tower crane

Hybrid battery + diesel systems sized for tower crane peak loads. Rent a generator half the size you'd otherwise need. Cut fuel costs. Stop oversizing for surges that happen 10% of the time.

The oversizing problem

Tower cranes draw heavy peak power during lift cycles — typically 200–400 kW for a few seconds at a time. Between lifts, the load drops to nearly zero. To handle the peak, contractors traditionally rent a generator sized for the peak — 250 kW, 400 kW, or larger. That generator then runs at 5–15% load most of the time, which is the worst possible operating condition.

How hybrid solves it

Add a battery to the system. The battery handles the lift peaks. The generator only sees the smooth average load — which is much smaller. You can rent a 100 kW or 125 kW generator instead of a 250 kW one. It runs at 60–80% load (its efficient sweet spot), uses far less fuel, lasts longer, and costs less to rent.

Real numbers from project case studies

  • 500 kW battery + 100 kW generator powered an 8-ton tower crane — generator runtime cut from 24 to 2.5 hours/day
  • 150 kW genset replaced with hybrid: 100 kW genset + battery, now runs only 6 hours/day — 70% diesel reduction
  • Tower crane site monthly fuel bill dropped from AED 28K to AED 5.5K with hybrid setup

Questions.

Tower cranes have huge peak loads (during lifts) but very low average loads (between lifts). A pure diesel generator has to be sized for the peak — meaning it runs inefficiently 90% of the time. A hybrid setup with a battery handles peaks separately.
Typically 40–50% smaller. A site that needed a 250 kW genset for a tower crane can usually drop to 100–125 kW with a battery in the loop.
Yes — battery output power is what matters for peak handling, not capacity. Our trailer units output up to 60 kW continuous and handle short-duration peaks well above that.
Same principle. Any equipment with surge loads and idle periods benefits from hybrid.
