Wiesbauer GmbH & Co. KG has added another Grove GMK6300L-1 to its fleet, further expanding its lifting capabilities at the Mannheim site. The new 300-tonne all-terrain crane will work alongside six other Grove cranes ranging from 60 to 300 tonnes, reinforcing the company’s role as a leading heavy-duty service provider in Baden-Württemberg.
This newest unit is the fourth GMK6300L-1 in the Wiesbauer fleet. It replaces an older model that will later be transferred to the company’s Bietigheim site. The crane was supplied by KranAgentur Werner, continuing the long-standing cooperation between the companies.
The GMK6300L-1 features an 80 m main boom capable of lifting 14 tonnes at a 28 m radius when fully extended. It is supported by a 12/21 m bi-fold swingaway jib, hydraulically adjustable between 5° and 40°. The crane’s Allison transmission, combined with an additional hydraulic retarder, ensures smooth driving and high efficiency. Modern additions such as LED work lights and a boom head camera system enhance safety and precision on site.
Wiesbauer has been a loyal Grove customer since 1965 and continues to rely on the manufacturer’s proven technology. The new GMK6300L-1 will further strengthen the company’s fleet, ensuring continued competitiveness in industrial, construction, and infrastructure projects.
