Abstract :
Although cranes are widely used for construction and loading operations, the casual observer rarely has the opportunity to view this technology up close. This article presents innovative control technology present in the mobile cranes produced by Terex Demag mobile cranes specializes in self-transporting road-capable cranes. These cranes are known for their versatility due to their high-capacity, telescoping booms. In particular, the Demag AC 160-1 mobile crane is a five-axle vehicle that uses an electro-hydraulic rear axle steering system, which increases maneuverability and enhances driver comfort. The cranes also employs advanced control techniques in their touch screen crane control system. This computerized system allows the operator to enter load data and desired operation sequences. An electronic load sensing system then controls the hydraulic pumps to maintain the necessary force levels. For safety in critical situations, such as near power installations or chemical plants, the operator can specify a safety zone, which cannot be penetrated by the boom. Finally, the operator can specify the gripping sensitivity of the manual controls to allow precision operation for assembly work.
