No three-phase, no problem

Situation

With an 8-storey apartment complex needing to start construction, but the project being held up because of noise restrictions and no access to 3-phase site power, Kalmar Construction was under pressure to find a solution to power their tower crane and the site power.

Overview

The Liebherr 542HC-L Luffing crane, on rent from SMITH Cranes, needed a maximum of 265kVA of peak-power available for the crane, but because the site only had single-phase power available, they believed the E-Gen300 battery system wasn’t going to provide a solution.

After contacting us, SMITH Cranes purchased the E-Gen300, which has both single-phase and 3-phase input charging, and 300kVA of peak-power, making it the perfect solution for this job.
