Merkel Autokrane<\/a> recently faced a special challenge at Bamberg port. Its job was to lift a port crane and laterally load it onto a ship. The port crane weighed 92 t and was 18 m in height, and was installed on a 3.5 m quay wall, which limited the available space for another crane to lift it, as it would have to be positioned between the quay wall and the Main-Danube canal.<\/p>\n

The crane’s available swing radius was less than 10 m; therefore, using a large crawler crane or mobile crane was not feasible. A Grove GMK5250L<\/a> however, was able to navigate the tight working quarters. Its compact dimensions, particularly in terms of outriggers, combined with its 250 t lifting capacity, made it an ideal choice. Merkel decided on a tandem lift with two GMK5250L<\/a>s, the second of which was provided by Aug\u00e9 GmbH of W\u00fcrzburg.<\/p>\n

\u201cThe quay wall bordering the jobsite made it impossible to deploy a larger crane,” said Merkel Autokrane field technician Karl-Heinz G\u00f6ring. “These circumstances made tandem lifting with the two compact Grove GMK5250L<\/a>s the most efficient solution for our approach to the project because they allowed us to make effective use of the available space and keep expenses as low as possible.”<\/p>\n

The company positioned the two GMK5250L<\/a>s directly next to the quay wall to the right and left of the port crane. Merkel’s GMK5250L was equipped with a counterweight of 80\u00a0t and for its share of the lift, raised 65\u00a0t; the crane from Aug\u00e9 was equipped with a 70 t counterweight and lifted the remaining 27\u00a0t of the port crane\u2019s base frame. Boom length on both cranes was 28.5\u00a0m, which enabled them to achieve the required lifting capacity, as well as a lift radius between 8\u00a0m and 10\u00a0m (8\u00a0m when lifting the port crane and 10\u00a0m during its lateral loading onto a ship anchored in the port).<\/p>\n

The two crane operators communicated with wireless radios and were able to coordinate their lifting plan with precision. Merkel had previously used its GMK5250L<\/a> to dismantle other components of the port crane, such as its boom. As a result, the work lasted five days, which included job site preparation and two days of tandem lifts of the base frame.<\/p>\n

Based in Bamberg, Merkel Autokrane has been performing lifting and transport services for its customers since 1998. It maintains a fleet of more than 25\u00a0mobile cranes, transport vehicles, and assembly tools. Aug\u00e9 of W\u00fcrzburg was founded in 1960 and offers truck cranes ranging from 25 t up to 250\u00a0t for a variety of applications. Both companies added the Grove GMK5250L<\/a> to their fleets in early 2015.<\/p>\n","protected":false},"excerpt":{"rendered":"
