Hitachi Sumitomo SCX1200-2 Parts Catalog – Factory OEM Specs for the Crawler Crane

If you’re wrenching on a Hitachi Sumitomo SCX1200-2, you need the actual factory parts breakdown. Aftermarket diagrams will get you ordering the wrong seal and burning a day. This is the OEM Parts Catalog – 530 pages of Hitachi Sumitomo SCX1200-2 components, with part numbers, quantities, and interchangeability codes straight from Hitachi Sumitomo. No guesswork, no cross-referencing generic lists.

You get exploded views for every major assembly: lower frame, slew ring, winch drums, right and left house units, cab, crane attachment, and even tower attachment options. Each part is listed with its unique part number and the number needed per machine. The service code symbols – explained on page 3 – tell you if a part requires local processing (W), is a service kit item (K), or is an optional piece (OP). That kind of detail keeps you from ordering the wrong piece and holding up a job.

Lower Frame and Travel Gear: Crawler Shoe and Tumbler IDs

The LOWER section of this catalog covers everything that touches the ground. You get exploded views for LOWER FRAME, SIDE FRAME INSTALL AND REMOVE DEVICE, CENTER JOINT, and the LUBRICATE PIPING (SLEWING RING). The TAKE-UP TUMBLER, UPPER ROLLER, LOWER ROLLER, and CRAWLER SHOE are all individually listed with their part numbers. Need the travel device assembly? That section includes the TRAVEL DEVICE, STEP, JACK-UP UNIT, and all related piping – TRAVEL PIPING (LOWER), CYL. PIPING (1) and (2), and the ELECTRIC PARTS (LOWER). Even the LEVEL gauge bracket is in there. If you’ve ever tried to match a crawler shoe from a third-party source, you know how often the bolt pattern is off. This catalog gives you the exact Hitachi Sumitomo part numbers.

Slewing Frame and Winch: Brake Valve and Drum Lock Parts

Moving up, the SLEWING FRAME section covers the entire upper rotating structure. You get detailed breakdowns for A-FRAME (1), (2), and (3), plus the HANGER and LUBRICATE PIPING (A-FRAME). The CONTROL VALVE (A-FRAME) and CONTROL VALVE (SLEWING) are shown with all their ports and seals. The VALVE (BRAKE), BRAKE SELECTING PIPING, and BRAKE COOLING PIPING are covered so you can identify the exact valve body or hose. Drum locks are split into DRUM LOCK (FRONT, REAR) and DRUM LOCK (DERRICKING). The WINCH section gives you DRUM SUPPORT (1) and (2), SLEWING MECHANISM, and DRUM REVOLUTION SENSOR. Every fastening point is listed – no hunting for obscure bolts.

Right and Left Unit: Piping, Valves, and Engine Components

The RIGHT UNIT section alone runs over a dozen subsections: BED (RIGHT) and BED (RIGHT-REAR), FUEL TANK and FUEL PIPING, two CONTROL VALVE groups, PUMP PIPING, HOSE SILENCER, DRUM PIPING, BOOM HOISTING PIPING, TRAVEL PIPING (SLEWING FRAME), RETURN PIPING, DRAIN PIPING, and multiple PILOT PARTS and PILOT PIPING entries (1-1, 1-2, 2-1, 2-2, R-1 through R-3, L, B, W). That’s the kind of detail that matters when you’re tracing a leak or building a hose kit. The LEFT UNIT section covers RADIATOR, PUMP UNIT, SUCTION PIPING, RETURN PIPING (LEFT), BED (LEFT), ENGINE CONTROL, ENGINE CONTROL MOTOR, TANK UNIT, and both ENGINE (1) and (2) assemblies. Engine-related parts are marked with code ‘Z’ so you know they are from the separate engine catalog. The cab section includes everything from the operator’s seat and safety lever to the air conditioner and moment limiter.

Crane Attachment and Tower: Boom Sections and Hook Assembly

This catalog does not stop at the base machine. The CRANE ATTACHMENT section covers UPPER BOOM, SIDE SHEAVE, LOWER BOOM, BRIDLE, BOOM OVERHOIST PREVENTION DEVICE, BOOM ANGLE INDICATOR, and multiple middle boom lengths (3m, 6m, 9m, and B 9m). Hook blocks are listed by capacity: 120t, 50t, 30t, and 11t hooks with all sheave parts. The SHORT JIB and SHORT JIB PARTS include their own overhoist prevention devices. Pendant ropes in 3m, 6m, and 9m are there. The TOWER ATTACHMENT section includes TOWER (UPPER), TOWER JIB (UPPER/LOWER), JIB STOP, SLEWING LEVER, and all associated overhoist and positioning indicator devices. Even the wiring parts for the tower rig are detailed.

Source Validity: Why OEM Beats Aftermarket

I have seen too many jobs go sideways because a tech used a third-party parts list that had a wrong part number. This catalog is the original Hitachi Sumitomo print – scanned from the factory document. The interchangeability codes (Y, I, P, T, D) on page 3 tell you exactly which parts swap and which don’t. The ‘R’ code means the quantity varies by serial number, so you know to measure, not guess. If you are ordering parts, you need the OEM document. Period.
