Drawing for Crusher Under Chassis Number 2587854: A Technical Overview
The drawing identified under chassis number 2587854 is the definitive engineering reference for the specific crusher unit bearing that serial number. It contains all dimensional, material, and assembly information required to manufacture, install, maintain, or repair the machine. Without this drawing, any attempt to service or replicate the crusher would rely on guesswork, leading to misalignment, premature wear, or catastrophic failure. The drawing serves as the single source of truth for every component—from the main frame and eccentric shaft to the toggle plate and jaw dies—ensuring that replacement parts fit exactly and that the machine operates within its designed tolerances. In short, this document is not merely a sketch; it is a legally binding technical specification that ties every physical part back to a unique production record.
Background and Context of Chassis Number 2587854
Chassis numbers are assigned by manufacturers to track each individual machine through its lifecycle. For heavy equipment like rock crushers—whether jaw crushers, cone crushers, or impactors—the chassis number is stamped into the main frame and appears on all original documentation. The number 2587854 likely corresponds to a specific production batch from a major OEM such as Metso Outotec, Sandvik, Terex, or Kleemann. In many factories, drawings are archived by chassis number so that when a customer orders a spare part decades later, the manufacturer can pull up exactly what was built. This practice is standard in industries governed by ISO 9001 quality management systems and ASME Y14.100 engineering drawing standards.
The drawing itself would have been created during the design phase of that particular model variant. Crusher designs evolve over time—minor changes in liner profiles, bolt patterns, or hydraulic system routing occur between serial numbers. Therefore a drawing tied to chassis number 2587854 captures those exact specifications rather than generic model-level information.
Content of the Drawing
A typical crusher assembly drawing includes multiple views: front elevation, side section through the crushing chamber, plan view of the base mounting points, and detailed callouts for critical interfaces. For chassis number 2587854’s drawing one would expect:
- Main frame dimensions: Overall length/width/height; location of mounting holes; thickness of side plates; weld symbols per AWS D1.1.
- Eccentric shaft assembly: Shaft diameter (likely metric), bearing seat tolerances (H7/k6 fits), keyway dimensions per DIN 6885.
- Toggle plate geometry: Angle relative to horizontal; thickness; material hardness specification (e.g., ASTM A514 Grade B).
- Jaw die profiles: Tooth pattern (straight vs curved); bolt hole locations; manganese steel grade (e.g., Hadfield steel with minimum Brinell hardness).
- Hydraulic cylinder ports: Thread sizes (BSPP or NPT); pressure ratings.
- Lubrication points: Grease fitting types; oil gallery routing.
All dimensions are given with tolerances following ISO 2768-mK or similar general tolerance standards. Surface roughness values appear on sliding surfaces such as toggle seat pockets and bearing journals.
Role in Manufacturing and Assembly
During production at the factory floor workers use this drawing as their primary instruction set. The welding department references it for preheat temperatures and interpass limits based on material thicknesses listed in a bill of materials attached to the same document number. Machinists set up CNC programs using coordinates extracted from dimension lines; they verify critical features with CMM reports against nominal values from this very sheet.
Assembly technicians follow an exploded view included in later sheets of the same drawing set (often called “drawing package”). They torque bolts according to values specified in notes: e.g., “Tighten pitman arm bolts to Class 10.9 torque per Table A.” Without these details two identical-looking machines could behave differently due to variations in preload.
Importance for Maintenance and Troubleshooting
When field failures occur—say a cracked jaw die after only three months—the service engineer pulls up chassis number’s drawing alongside wear records from previous inspections on other units with same serial range. By comparing actual wear patterns against theoretical contact angles shown on cross-section views he can diagnose whether feed size exceeded design limits or if toggle angle shifted due to loose tension rod nuts.
Spare parts procurement relies entirely on correct part numbers derived from this drawing’s item list each component has an alphanumeric code like “Jaw-Die-LH-2587854-A” which matches inventory systems globally ordering wrong liner will cause premature failure because bolt hole spacing differs even between consecutive chassis numbers if minor revisions were made mid-production run without updating model name only internal drawings reflect those changes hence why OEMs insist customers provide full chassis identification when ordering parts.jpg)
Traceability Through Chassis Number Linkage
Every revision history note appears directly on this document engineers stamp dates initials description change e g “Rev B – increased flywheel bore clearance by +0 mm due field reports binding” Such annotations allow maintenance teams understand why certain components differ from earlier machines same model they also enable legal liability tracking if design flaw discovered later manufacturer can identify exactly which units affected using range including #2587854
In many jurisdictions equipment safety regulations require operators keep copies original drawings accessible during inspections regulatory bodies like MSHA Canada check whether maintenance performed according manufacturer specifications documented via these very sheets
Digital Transformation Considerations
Modern practice involves scanning original paper drawings into PDF files linked database keyed by chassis number however many older machines still have hand-drawn blueprints stored climate-controlled archives For #2587854 likely exists both physical mylar copy microfilm version plus recent CAD conversion but original remains authoritative because conversion software sometimes misinterprets faint lines leading phantom dimensions experienced technicians always cross-check digital file against paper original before cutting expensive replacement parts
Some OEMs now offer online portals where entering chassis number retrieves latest revision automatically eliminating risk using obsolete version This trend reduces errors but requires internet access which not always available remote mining sites therefore printed copy kept toolbox remains essential backup

Drawing for crusher under chassis number #2587854 encapsulates decades engineering knowledge into single coherent document It bridges gap between abstract design intent tangible machine reality Without it every repair becomes gamble every replacement part potential mismatch Every operator should understand value preserving legible copy along with log all modifications made over life unit Only then can machine continue delivering rated throughput while meeting safety reliability expectations originally built into those lines ink
