This is where we come from. This is who we are.
Sommer Kranverleih GmbH is a Bremen family business founded in 1959, now in its third generation, headquartered in the Bremen industrial port. The company offers crane rental and crane operations with mobile cranes from 40 t to 800 t lifting capacity, including city cranes for confined hall conditions, mobile construction cranes, telescopic crawlers for precast element assembly, and special solutions. The portfolio is complemented by heavy-duty transports, loading and unloading of heavy and bulky goods, and the transport of complex loads to hard-to-reach locations. A key focus is services for the wind energy sector, including repowering, major component replacement, tower construction, and dismantling. In addition, equipment such as test weights, spreader beams, excavator mats, road plates, man baskets, and lighting systems is available for rent, and cranes from the company's own fleet are sold. Customers come from wind energy, major industry, the North German port industry, and precast element assembly.
