Double-Tapered Boom Crane

Lower your crane maintenance costs with a Double Tapered Boom crane from Allied Marine Crane. A sealed box boom gives you high capacity with low maintenance. Double-tapered booms have the strength of a regular square section boom with a fraction of the weight. With optional pinned boom joints, the DT series can be efficiently stored and transported. Boom lengths up to 125 feet and capacities of up to 125 tons allow the Double Taper Boom crane to match many applications. If you are looking for lightweight strength and economical maintenance, look no further than the Allied DT Crane.
