Structural support frame, Caterpillar original part.
Technical Description
The component is a heavy-duty steel plate assembly, commonly used on Caterpillar 352-series
excavators. It serves a critical structural role, providing support to essential machine parts like
the swing frame, upper undercarriage mounting, or counterweight brackets.
Material: High-strength steel casting
Surface: Machined for precision fitment; typically painted Caterpillar yellow for corrosion
resistance
Compatibility: Designed specifically for the Cat 352 excavator platform (e.g., 352-F, 352-L,
352-N)
Function & Application
This plate assembly performs several vital functions:
Upper Frame Support – It integrates into the main structural frame, providing stiffness to resist
torsional loads.
Counterweight Linkage – Acts as a mounting bracket for the heavy rear counterweight, ensuring
proper weight distribution.
Under-Carriage Connection – Serves as a flange to mount track frame assemblies or to attach
the swing frame itself.
Design Features – Caterpillar built 352 excavators with reinforced frames and upper structures
to withstand rigorous quarry and mining tasks
