This fastening bolt, identified by part number 509 835 99, serves as a connecting element within the Demag AC80-1 mobile crane. It is engineered to secure components together, maintaining the structural integrity of the crane by resisting the tensile and shear forces encountered during operation. The bolt is utilized across multiple systems, including the boom assembly, chassis, counterweight systems, and outrigger structures, where a firm connection between parts is required to support both static and dynamic loads.
This component is specifically intended for fitment on the Demag AC80-1 crane. Proper installation ensures that the connected assemblies remain correctly positioned during the crane's duty cycle. When performing maintenance, it is necessary to verify that the bolt thread and dimensions match the original specifications required for the specific joint to prevent loosening or structural deformation under load.
In heavy machinery, fastening bolts of this type are used to join structural members and mechanical sub-assemblies. They provide the clamping force necessary to hold components in place while allowing for the transfer of operational loads through the machine's frame and subsystems.
