Stevenson Crane is proud to introduce Linden Comansa flat-top tower crane technology to Chicago. Comansa tower cranes are different from other towers you see on the skyline in both appearance and function. First, they eliminated the pendant lines so it is now easier to operate multiple cranes on your job with minimum interference/overlap. Next, Comansa tower cranes feature pin-jointed mast sections that are low maintenance and can be broken down to reduce transportation costs. Last, and most important to you, the mast panels were designed to rest on the corner angles of the mast sections allowing for faster, safer erection and dismantling.

Not only are Linden Comansa tower cranes engineered for a more cost effective assembly, but Stevenson offers a turnkey tower crane erection process. Our turnkey service covers:

• Tower crane rental
• Operator/oiler if needed
• Assist crane for erection, jumps and tear-down
• Erection crew and mechanic during erection, jump and tear-down
• 250 hour maintenance
• Any as-needed maintenance and repair
