Lining plate for Demag AC80-1

The lining plate, part number 529 689 40, is used in the Demag AC80-1 crane to assist in the precise positioning and spacing of machine assemblies. It functions as an adjustment shim to maintain the correct gap or alignment between mating surfaces, which is necessary for the structural integrity of the crane. By providing a uniform contact area, this component helps distribute loads across the assembly, preventing localized stress concentrations that can occur during crane operations.

This part is specifically engineered for the Demag AC80-1 model. It is typically installed in areas requiring fine-tuned clearances, such as boom support points, slewing mechanisms, or stabilizer mounts. Proper installation of this plate ensures that the machine maintains its design tolerances and operational stability.

In heavy machinery, lining plates and shims are used to compensate for manufacturing variations and to manage the fit between components. They provide a stable interface that prevents metal-to-metal contact and helps maintain the alignment of moving or structural parts. By ensuring that components are correctly spaced, these plates help manage the mechanical forces transmitted through the crane structure during lifting and rotation tasks.
