Description
The U.S. Army Corps of Engineers - Vicksburg District (USACE-MVK) intends to award a sole source purchase order to Liebherr-America, Inc. for the procurement of one new commercial-grade crawler crane optimized for floating marine service. The crane will be used for maintenance on locks and dams, clearing and snagging, bank erosion work, bank stabilization, and other navigable waterways throughout the Vicksburg District and the region. The crane must meet specific technical requirements, including a 140-145 ft main boom, a removable boom tip extension, and the ability to perform heavy lifting, grapple rip rap operation, clam shell dredging, pile driving, and auxiliary lift with personnel handling. The contractor must also provide training and technical support for the crane.
• The crane must be capable of lifting at least 94,000 lb at a 60-ft radius from its axis of rotation using the 140/145-ft main boom.
• The crane must be capable of lifting 25,000 lb (including the attachment) at a 120-ft radius from its axis of rotation using the 140/145-ft boom during dragline operations.
• The crane must be capable of lifting 40,000 lb (including the attachment) at an 80-ft radius from its axis of rotation using the 140/145-ft boom during clamshell operations.
• The crane must be capable of switching between each operational mode and heavy lift without requiring re-spooling of any hoist drum or reconfiguring the counterweights.
