ROHLIG SUUS Logistik (RSL) is one of the largest logistics service providers in Poland. It employs around 1400 staff and generates a turnover of just under EUR 2 billion. RSL primarily operates in the areas of contract logistics; sea, air, road and rail transport; intermodal freight transport; project cargoes and customs services. The company maintains a total storage area of 200,000 m2, spread over multiple logistics centres and hubs.
Since 2013, RSL has been running a fleet of battery-operated forklift trucks for goods handling at its warehouses and cross-docking terminals. The fleet is frequently required to operate around the clock; therefore almost all forklift trucks are fitted with two batteries. The challenge is to run a fleet made up of several different types of forklift trucks and therefore powered by different batteries with varying voltages and capacities. Conventional charging technology requires batteries to be matched with a specific charger – any errors could result in costly damage to the battery.
From the very beginning, ROHLIG SUUS has relied on the smart Selectiva battery chargers from Fronius. The chargers automatically recognise the voltage, which means it is possible to charge batteries with different nominal voltages and avoid operating faults. The regulated charging process protects the batteries and ensures they remain available in the long-term. ROHLIG SUUS is also well prepared for any future changes, be it expansions or modifications, since the devices themselves, and also the connections and infrastructure, are all standardised.
