Document Structure and Component Identification

This manual provides an exhaustive index of structural components for the IHI 30NX series. It facilitates parts sales and servicing by mapping exploded-view diagrams to specific part numbers, quantities, and interchangeability status. The documentation is organized into clear sections starting with the Lower Machine, followed by Turntable and Swing Bearing assemblies, Swing Drive Devices, and comprehensive Hydraulic Piping configurations for the various machine iterations produced over the 1999–2005 period.

Hydraulic and Mechanical Specification Highlights

Detailed specifications within the catalog provide vital identification data for maintenance and repair. The main pump assembly establishes 21 MPa (3,050 psi) as the standard working pressure for all hydraulic circuits. Hydraulic oil tank capacity is determined at 50–60 L (13.2–15.9 US gal) for effective system cooling and replenishment. Relief valve settings are documented within 140–185 kPa (20.3–26.8 psi) to maintain system integrity. The dual traction motor assembly governs 2.0 kW (2.7 hp) per unit for ground movement.
