HeavyEQ parts intelligence
Legacy crusher research: historical names do not identify every chamber
Research first. Identify the installed component. Confirm the application.
Historical machine names can help locate evidence after product lines change. Keep the original plant, crusher and component designations intact, with the source that supports each relationship. A familiar brand, approximate size or recorded launch event cannot establish a replacement part or production interval.
Plant and installed unit are separate · Supplier references remain attributed · Chamber fitment unverified
Retain the requested position, profile, material and source. A shared guide does not select a machine or create stock.
Separate a name observation from a machine identity
A supplier catalogue can mention a legacy crusher family while leaving the exact manufacturer record, revision and regional designation unresolved. Preserve that supplier attribution. Do not create a new canonical model merely because a parts table contains a name, and do not remove a suffix to force a match with another machine. Existing HeavyEQ specification identities retain their canonical ownership. Unmatched historical labels remain research candidates until sufficient distinct machine evidence exists.
Preserve explicit manufacturer naming history
Sandvik’s current product pages identify CH430 as formerly H3800 and CH440 as formerly H4800. These are two source-backed historical naming observations. They help find documentation without proving common liner geometry across time. Keep head, bowl and chamber revisions independent. A replacement assembly or later service change needs its own evidence, and a naming relationship supplies no reverse interchange or chain connecting every historical wear component to a current product.
Treat launch dates as events
Finlay’s history records the J-1175 launch in 2005 and introduction of J-1160 in 2007, alongside later development events. Retain the event wording and model scope. An introduction date is not a machine’s complete production range, its component revision date or the start of a wear-part fitment interval. Do not convert it into a year filter that selects parts. A current product page likewise cannot document every older build or modification.
Build the sourcing record around the installation
For a legacy cone, record the actual head and bowl configuration rather than relying only on nominal diameter. For a jaw, retain the box and fixed or moving position; for an impactor, identify the rotor and retention arrangement. Ask a genuine seller for readable markings, donor evidence, condition and included components. Undocumented dimensions, metallurgy and years stay unknown. A private RFQ can preserve the incomplete historical context without certifying an application or implying that HeavyEQ holds a licensed legacy catalogue.
