A complete equipment package for active construction sites
Tower cranes, plant equipment, night-shift lighting, perimeter security — one site, many equipment needs. Johank supplies hybrid power and area lighting from one supplier, deployable on the same truck.
Power, lighting, deployment — sized to your site
A typical construction site uses two product lines from Johank. Pick by load, scale, and how much night work you need.
KCG600E-POWER
600 kVA hybrid for tower cranes, heavy plant and full-shift sites with significant low-load periods.
KCG300E-POWER
300 kVA hybrid for inner-city projects, smaller sites, or lower-load applications. LEZ-ready.
KCL2000-LED
Self-powered LED light towers for night-shift work, perimeter and access-route lighting. Deploy ×N around the site.
Why diesel-only sites lose money
Construction sites have a duty cycle that diesel was never designed for: long low-load periods, occasional peaks, 24-hour operation, and area lighting that runs all night.
Low-load fuel waste
Gensets sized for peak demand run at 20–30% load most of the day. Diesel efficiency drops sharply below 40% load.
Night-time noise
Security, CCTV and lighting loads are small but the diesel still runs all night. Neighbours complain. LEZ rules tighten.
Mains lighting gaps
Temporary site lighting strung off mains needs cable runs, transformers, and a competent electrician. Mobile light towers replace all that.
Urban compliance
Stage V, Low Emission Zones and ESG reporting are becoming conditions for winning contracts in European cities.
Hybrid power + mobile lighting, deployed together
During the day, the ENERGYPACK EMS manages load sharing between diesel and battery. When the crane lifts, both sources support the peak. Between lifts, the battery carries the load alone while the diesel charges or shuts down.
At night, the battery can run security, CCTV and lighting silently — no diesel noise, no exhaust, no fuel consumption until the next shift starts.
For working areas the main genset can't reach with a cable run, KCL2000-LED light towers fill the gap. Self-powered, deployable in minutes, repositionable as the site grows.
