Polrena was born from a passion for construction machinery and as a response to the real needs of the European crane market. Since 2020, we have been connecting companies that require reliable top- and bottom-slewing Liebherr tower cranes with those offering proven, used equipment ready for further operation. Our mission is to support clients in making informed purchasing decisions and to provide access to trusted solutions in the crane and construction machinery sectors.
We operate wherever professional crane solutions are needed – from Lisbon to Riga, across Central, Southern, and Eastern Europe. Polrena is not a typical machinery dealer – we act as a technical partner and market connector, helping clients select the right equipment, understand configurations, and plan logistics efficiently.
Our core specialization is in trading used Liebherr tower cranes, including both top- and bottom-slewing cranes. With extensive technical knowledge and hands-on market experience, we provide advice on crane configurations, assembly, and disassembly. While we do not provide refurbishment or overhaul services, we offer reliable technical insights and realistic recommendations.
We also support clients in the area of crawler machines, such as pile drivers and drilling rigs, offering both used equipment sales and access to spare parts. In our Machinery section, clients can browse available used machines and components, making it easy to identify the right equipment for specific projects.
Transport is a crucial element of crane and machinery trading. Although equipment is rarely offered with delivery included, we actively assist clients in organizing safe and efficient transport, sharing proven solutions and industry experience. We also support cross-border transactions and logistics planning to ensure smooth project execution.
