3D Scanning for Heavy Equipment Refurbishers | Pin RE, Structural Inspection & Attachment Geometry | Schimmel Engineering Nashville

For Heavy Equipment Refurbishers, Remanufacturers & Fleet Shops

The OEM pin is on back-order for twelve weeks. The boom took a hit and nobody can agree on whether it's straight. The machine needs a custom attachment and the fabricator needs to know what the coupler actually measures. Whatever the situation — if you need exact geometry of what's on a piece of heavy iron — that's what we do.

We come to your yard, shop, or job site. Carry-in cases, battery-powered, no infrastructure required. The scanner deploys in 20 minutes — on a machine that can't move, in a muddy yard, or inside a shop at night. The HandyScan MAX Elite handles equipment up to 15 meters. Deliverables typically within 5 business days.

Worn Pin & Bore — Reverse Engineering & Geometry Reconstruction

Excavator arm pins, bucket pivot bores, dozer blade pivot geometry, articulation joint components, and undercarriage pivot hardware. When the OEM part is discontinued, on a 12-week back-order, or priced at a premium that doesn't make sense for the machine's value, we scan the worn component, reconstruct the original nominal geometry, and deliver a STEP model the machine shop can cut a replacement from in steel. Common on older Cat, Komatsu, Deere, and Volvo models where parts availability has thinned out.

Est. per component

Bucket & Attachment Wear Profile Scan

Worn bucket lip geometry, side plate profiles, and wear pattern documentation for replacement fabrication and rebuild planning. The fabricator gets the actual bucket geometry — current wear condition and original profile where steel survives — not a nominal drawing from the OEM that may not reflect field modifications, previous rebuilds, or the specific wear pattern this machine develops in this application. Also used for specialty attachment geometry where a custom lip profile or cutting edge has been developed over time.

Structural Distortion Assessment — Boom, Stick, Crane Boom & Main Frame

Boom arms, stick tubes, crane booms, and main frames scanned after collision, overload, or suspected structural damage. Deviation mapped against nominal geometry — either the OEM drawing, a known-good reference machine, or a symmetry-based nominal we construct from the undamaged side. The report shows where the structure has bent or twisted, by how much, and in which direction. Objective basis for a straighten, repair, or condemn decision — documented, not estimated.

Custom Attachment Design Geometry — Coupler & Linkage Scan

Machine coupler, quick-connect mounting geometry, pin positions, and linkage range of motion captured so a custom attachment can be designed to fit this specific machine. Grapples, thumbs, compactors, pile drivers, augers, and specialty tools all require pin spacing, mounting face geometry, and range-of-motion clearances that match the host machine — not a generic spec. We give the fabricator the actual machine geometry before steel is ordered. Works on all coupler types including OilQuick, Lehnhoff, Miller, and proprietary OEM quick-connects.

Discontinued Cab Component & Glass Templating Scan

Cab frame openings, door frame geometry, window apertures, and seal profiles scanned for replacement glass cutting and cab panel fabrication on machines where OEM parts are no longer available. The glass cutter receives an exact template of the opening — not a tape-measure approximation. Seal groove profiles and retainer geometry can also be captured for custom rubber fabrication. Common on 1980s–2000s vintage machines from discontinued product lines.
From $750
Est. per opening

Fleet Condition Documentation — Pre-Auction & Pre-Transfer Scan

Full machine geometry captured before auction, fleet transfer, rental return, or lease end — boom and stick condition, bucket wear, structural geometry, and component positions documented at the point of inspection. If a condition dispute arises after transfer, the scan record is the reference. For rental fleets, a scan at check-out and check-in gives both parties objective data on what changed during the rental period. More reliable than photos, more complete than a visual inspection report.

Counterweight & Ballast Geometry Scan

Counterweight mounting bracket geometry, attachment face profile, and mass distribution profile captured for custom counterweight fabrication. Used on long-reach configurations, modified machines, and specialty builds where OEM counterweight options don't balance the modified configuration. The fabricator receives exact mounting geometry and a dimensional baseline for the ballast mass target.

When Refurbishers Call Us

Scenario — Discontinued OEM pin
The stick pin is worn out. OEM says 14 weeks and $3,200. The machine is worth $40,000.
A mid-2000s Cat 320 stick pin worn beyond serviceability. OEM back-order is 14 weeks and the cost doesn't pencil against the machine value. We scan the worn pin, reconstruct the original nominal geometry, and deliver a STEP model to a local machine shop. Custom pin machined in 4140 steel, delivered in 10 days, at a fraction of OEM cost. Machine goes back to work. No wait, no back-order, no freight from overseas.
Scenario — Boom collision damage
The boom took a hit from a concrete wall. The owner wants to know if it's straight before putting it back in service.
A PC200 boom that contacted a structure at working speed. Visually it looks okay. The owner wants objective data before putting an operator back in the seat. We scan the full boom and stick, compare against nominal geometry derived from the undamaged opposite side and OEM reference dimensions, and produce a deviation map showing exactly where the structure moved and by how much. The shop gets the data to make an informed repair-or-condemn call — not a guess based on a level and a tape measure.
Scenario — Custom attachment
A fabricator needs to build a custom grapple for a Volvo EC250. The quick-connect is proprietary and there are no drawings.
A custom demolition grapple needs to fit a Volvo EC250 with a Volvo-proprietary quick-connect. The fabricator can't find drawings for the coupler geometry, and the machine can't go to the shop. We come to the machine, scan the coupler — pin positions, mounting face geometry, carrier arm clearances, hydraulic port locations — and give the fabricator a complete geometric dataset to design the attachment from. The grapple is designed in CAD around the real machine before a single piece of steel is ordered.
Scenario — Fleet auction prep
A fleet of 12 machines is going to auction. The seller wants condition documentation before they leave the yard.
A contractor retiring a fleet of mixed excavators and wheel loaders. Before the machines go to auction, the seller wants an objective record of structural condition, bucket wear, and component positions — both to establish value and to protect against post-sale condition disputes. We document each machine systematically and deliver a complete condition record. The auction house and buyers have objective data, not competing verbal descriptions of machine condition.
Scenario — Cab glass replacement
A vintage Liebherr has a cracked rear windshield. OEM glass was discontinued in 2008.
A 1990s Liebherr LTM crane with a cracked rear cab window. The OEM glass was out of production for 15 years. A glass shop can cut it from flat stock but needs an exact template of the opening — shape, radius at each corner, and the exact dimensions of the retainer groove. We scan the cab frame opening and give the glass cutter a precise digital template. Replacement glass cut, fitted, and sealed without guesswork.
Scenario — Rental return condition dispute
A machine came back from a 6-month rental with damage the operator denies causing. Nobody documented condition at check-out.
A common problem with no good solution after the fact. The solution for next time: scan the machine at check-out. A complete geometric record of structural condition, bucket wear, and component positions takes two hours to capture and produces an objective baseline. At return, the post-rental scan is compared against the check-out scan. What changed during the rental period is documented — not disputed.

Questions from Equipment Refurbishers & Fleet Shops

Can you make a replacement pin or bushing from a scan when the OEM part is discontinued?
Yes. We scan the worn component, perform interpretative geometry reconstruction to identify the original nominal dimensions, and deliver a STEP model the machine shop cuts from. Custom pins and bushings machined to a scan-derived model are typically faster than OEM back-orders and can be made in whatever material specification the application requires — standard 4140, case-hardened, or upgraded steel for high-cycle applications.
Can you assess whether a boom or main frame is straight after a collision?
Yes. We scan the full boom, stick, or main frame and deviation-map it against nominal geometry. The nominal is derived from the OEM drawing if available, from a known-good reference machine, or from a symmetry model built from the undamaged side of the structure. The deviation report shows exactly where the steel moved, in which direction, and by how much — giving the repair shop an objective basis for a straighten or condemn decision rather than an eyeball estimate.
Can you scan a machine in a muddy yard or outdoor environment?
Yes. The scanner operates from battery, requires no controlled environment, and handles outdoor conditions. Surface contamination — mud, grease, paint — can affect scan quality on small detailed features but is generally manageable on the larger structural geometry that matters for heavy equipment work. We discuss surface preparation requirements during scope review. For internal bore and pin geometry, the component typically needs to be clean and ideally removed from the machine for full surface access.
Can you scan a coupler or quick-connect so a fabricator can design a custom attachment?
Yes. We capture the coupler's pin positions, mounting face geometry, carrier arm clearances, and hydraulic port locations. The fabricator designs the attachment in CAD against the real machine geometry before any steel is ordered. Works on all coupler types including OilQuick, Lehnhoff, Miller, Engcon, and proprietary OEM quick-connects where drawings are unavailable.
What size machines can you scan?
The HandyScan MAX Elite handles objects up to 15 meters — sufficient for excavators, dozers, motor graders, crawler cranes, and large wheel loaders. For components and precision detail work (pins, bores, couplers), we use the HandyScan Black Elite at 0.025mm accuracy. We bring both instruments and select based on the object and what the geometry is needed for.
Can you document a fleet of machines before auction?
Yes. For fleet documentation, we scan each machine systematically — typically two to four hours per machine depending on size and scope — and deliver a complete condition record for each unit. For large fleets, we work out a multi-day schedule that minimizes yard disruption. The documentation gives buyers and sellers an objective basis for valuation and protects against post-auction condition disputes.
