ALM completes challenging indoor tandem lift with Groves

Alsace Levage Manutention (ALM) used two of its Grove all-terrain cranes to complete a technical indoor tandem lift that required unique crane configurations and load charts.

ALM paired a GMK3050-1 with a GMK5250L for the project, which required the positioning of a 50 t zinc tray at an industrial plant. Both cranes were configured with minimal boom lengths, and operators lowered them to a minimum angle to account for the low headroom on site. Using the cranes’ telescoping boom abilities, the operators were able to lift and position the zinc tray at an extremely low angle. Special dispensation was made to bypass the cranes’ anti-two-block system to allow them to lift as close to the facility roof as possible. Hoist speeds were also reduced, and an additional supervisor was employed to check the distance between the boom nose and hook block, ensuring the lift was performed optimally.

“We are proud that our cranes provide daily solutions to our customers,” said Philippe Dumas, Manitowoc sales director for France. “ALM is one of our premier customers. In December we delivered one of the first GMK4100L-1 models to the company. The company chose this additional Grove all-terrain for its best-in-class, four-axle taxi configuration.”

ALM is headquartered in Illkirch-Graffenstaden, a suburb of Strasbourg in France. The company has a total of six Grove cranes in its fleet.
