Document Structure and Component Identification

This catalog provides an exhaustive structural index for the IHI 30NX series. It directly maps exploded-view diagrams to specific part numbers, quantities, and interchangeability status. You get a clear, unobstructed breakdown of the machine's architecture. The documentation walks through distinct sections starting with the Lower Machine. It then covers the Turntable and Swing Bearing assemblies, moving into the Swing Drive Devices and the comprehensive Hydraulic Piping configurations used across the 1999–2005 production run. This layout drastically cuts down the time spent hunting for the correct replacement part in the shop.

Hydraulic and Mechanical Specification Highlights

Beyond simple parts identification, the catalog includes crucial mechanical data to verify components before ordering. The main pump assembly establishes 21 MPa (3,050 psi) as the standard working pressure for all hydraulic circuits. You will also find system capacities, such as the hydraulic oil tank rated at 50–60 L (13.2–15.9 US gal), alongside relief valve settings documented at 140–185 kPa (20.3–26.8 psi). The dual traction motor assembly governs 2.0 kW (2.7 hp) per unit. Before undertaking any service or replacing components based on these schematics, ensure you review standard heavy equipment safety procedures or consult a certified technician to maintain system integrity.
