Engineered Parts, CNC Machined Components & Custom Manufactured Crane Spares

Precision replacement parts and practical manufacturing solutions for cranes, machinery and industrial equipment.

AC Crane Maintenance supplies and supports engineered parts, CNC machined components, reverse engineered crane spares, custom manufactured machine parts and industrial replacement components for overhead cranes, hoists, gantries, factories, mines and production plants.

When OEM parts are expensive, discontinued, delayed or unavailable, we can assist with practical replacement solutions using drawings, samples, measurements and technical information. From crane wheels, shafts, bushes and couplings to brackets, pins, rollers, gears, drums and fabricated components, we help clients keep critical equipment moving.

Replacement Parts for Cranes, Hoists, Machines & Industrial Equipment

Our engineered parts support covers breakdown repairs, crane refurbishments, maintenance, equipment upgrades and obsolete components where standard off-the-shelf parts are not available.

We can assist with once-off components, small batches and replacement parts manufactured to suit the application.

⚙

Crane Wheels & Rollers

Replacement crane wheels, guide rollers, load wheels, trolley wheels and custom rollers for overhead cranes, gantries and industrial equipment.

↔

Shafts, Pins & Bushes

Machined shafts, hinge pins, pivot pins, bushes, sleeves, spacers and wear components for crane and machine repair work.

◈

Couplings & Drive Parts

Couplings, hubs, adapters, gearbox-related components and mechanical drive spares for lifting and travel systems.

▣

Brackets & Fabricated Parts

Custom brackets, plates, guards, mounting parts, supports, stops, end-carriage components and fabricated assemblies.

◎

Drums, Sheaves & Rope Parts

Selected rope drums, sheaves, pulleys, spacers and components for hoist and lifting equipment maintenance and repairs.

✓

Obsolete OEM Replacements

Reverse engineered replacement parts for older cranes, imported machinery and legacy equipment where original parts are delayed or discontinued.

Local replacement solutions: When production equipment is standing, waiting for imported parts can cause costly downtime. We help clients identify, measure and source manufactured alternatives where a suitable engineered solution is possible.
What We Need to Quote Correctly

For CNC Machined Parts & Special Components, Technical Drawings Are Preferred

The best starting point for accurate manufacturing and pricing is a proper engineering drawing or CAD file showing dimensions, tolerances, material and quantity.

If no drawing is available, we can review the enquiry using a sample, damaged component, hand sketch, clear photographs and measured sizes.

▤

Best Information to Send

More complete information supports faster pricing, improved accuracy and reduced manufacturing risk.

  • Technical drawing or CAD file
  • Material specification
  • Quantity required
  • Critical dimensions and tolerances
  • Photos of the installation
  • Old sample part, if available
  • Application and operating conditions
⌕

If No Drawing Is Available

We can still assess many enquiries if sufficient practical information is supplied.

  • Send the sample for inspection
  • Provide a hand sketch with dimensions
  • Send photos from multiple angles
  • Measure bores, shafts and overall length
  • Identify keyways, threads and bolt holes
  • Explain where the part is installed
  • Describe how the original part failed
Precision and safety-critical components: High-speed, load-bearing and close-tolerance components may require additional measurements, material verification, hardness requirements, sample inspection or engineering review before manufacturing.
CNC Turning, Milling & Fabrication

Manufacturing Support for Precision Engineered Components

Engineered parts can involve CNC turning, milling, conventional machining, drilling, tapping, boring, slotting, grinding, welding and fabrication.

Material selection, tolerances and finishing processes depend on the component and its operating application.

⚙

CNC & Machined Parts

Precision-machined components for crane, hoist and industrial production equipment.

  • CNC turned parts
  • CNC milled components
  • Machined shafts and sleeves
  • Bushes, pins and spacers
  • Keyways, bores and threads
  • Small-batch production
▣

Fabricated & Repaired Components

Structural, mechanical and welded parts for crane and industrial maintenance applications.

  • Mounting brackets
  • End stops and guards
  • Base plates and supports
  • Repair plates and adapters
  • Welded assemblies
  • Custom steel components
Reverse Engineering & Obsolete Spares

Original Part Unavailable? We Can Review a Replacement.

An obsolete crane or machine part does not always mean the equipment must be replaced.

Where technically suitable, an existing component can be inspected, measured and used as the basis for a manufactured replacement.

This is particularly useful for older cranes, imported equipment, legacy gearboxes and specialised industrial machinery.

⌕

Typical Reverse Engineering Process

  • Review the original component or sample
  • Confirm application and operating duty
  • Measure critical dimensions and fits
  • Review material and wear requirements
  • Prepare manufacturing information
  • Quote suitable manufacturing options
  • Arrange production and inspection

Frequently Asked Questions

CNC Machining, Reverse Engineering & Custom Parts FAQs

Can you manufacture replacement crane parts?
AC Crane Maintenance supports enquiries for manufactured crane replacement components including wheels, shafts, bushes, pins, rollers, brackets and other engineered spares. Suitability depends on the part, available information and application requirements.
Do I need a technical drawing for CNC machining?
Technical drawings or CAD files are preferred because they help define dimensions, materials, tolerances and manufacturing requirements. Where drawings are unavailable, a sample or measured sketch may be sufficient for an initial review.
Can you reverse engineer an obsolete machine part?
We can review obsolete or discontinued components using samples, dimensions, photographs and application details. Safety-critical or highly stressed parts may require additional engineering verification.
Can you help with once-off and small-batch parts?
We can assess enquiries for individual replacement components and small production batches, subject to manufacturing feasibility and quotation requirements.
What information should I send for a quotation?
Send the technical drawing or CAD file where available, material details, dimensions, quantities, photographs, application information and a sample part if possible.
Can a damaged component be used as a sample?
In some cases, yes. A damaged part can provide useful dimensions and geometry, but worn or distorted surfaces may need additional measurements or engineering review.
