Components Built to Drawing, Certified to Specification
Every product we supply starts with a drawing or a specification — yours, not ours. We do not sell from a catalogue and we do not propose standard alternatives when a proprietary geometry is specified. The component you need is the component we produce, in the material grade required, to the dimensional tolerances on the drawing, with the heat treatment and inspection documentation that confirms it.
Our product range covers the components that take the most punishment in mining and bulk handling systems: the wear parts that contact abrasive material directly, the structural components that transmit loads through the system, and the transmission and drive components that keep everything moving. Each category has different material and manufacturing requirements; the common thread is that all of them are produced under a quality management system that documents what was made, how, and to what specification.
Crusher Wear Parts
Jaw plates, crusher hammers, impact plates, cone crusher liners, and secondary crusher wear parts — in manganese steel grades from Mn13 to Mn22, high-chromium white iron, and alloy steel for applications where standard grades are insufficient. Material grade selection is matched to the crusher type, crushing stage, feed material hardness, and impact energy, not applied as a default. Heat treatment is documented per batch; hardness is verified and recorded before shipment.
Crusher structural spares — mainshafts, eccentric sleeves, toggle plates, and frame castings — are produced to OEM drawings for jaw and cone crusher models used in aggregate, mining, and quarrying. Mainshafts are open-die forged in 42CrMo4 for fatigue resistance; eccentric sleeves are centrifugal-cast in high-lead bronze for hydrodynamic bearing performance. Long-term supply to North American and international crusher OEMs and operators.
Scraper Conveyor Components
Structural and chain components for armored face conveyors, stage loaders, and surface scraper conveyors — pan sides, connecting housings, scraper blades, sidewalls, and AFC chain components. Pan side dimensional accuracy at chain rail and pan joint interfaces is verified against drawing tolerance on every batch; the relationship between these tolerances and chain fatigue life is documented in our technical article on AFC dimensional tolerances.
AFC system components for longwall coal mining are produced to OEM drawings for systems in the 750mm to 1200mm pan width range, to European longwall equipment dimensional standards. Supply of AFC structural components — particularly pan sides and connecting housings — to European longwall equipment manufacturers is an established part of our business, conducted under NDA and supported by first-article approval and batch quality documentation.

Belt Conveyor Components
Rollers and idlers, drive and tail pulleys, conveyor frames and structural supports, guides, and transfer chute components for surface mining, port and terminal, and heavy industrial belt conveyor systems. Custom dimensions to project drawings — roller diameter and face width, pulley shell diameter and lagging specification, structural profiles and connection geometry. Dynamic balancing available for high-speed roller applications.
Drive units for heavy mining belt conveyors — cylindrical-planetary gearboxes from 250kW to 1,800kW per drive unit, produced to client drawings for CST and variable-frequency drive integration. For long-distance, high-capacity underground and surface conveyors where multi-drive arrangements and controlled start behaviour are required, the gearbox specification is matched to the full drive system design, not selected independently.

Heavy Cast Steel Components
Structural and transmission castings for mining drive systems, material handling equipment, and heavy industrial machinery — planetary carriers, industrial gearbox housings, chute sidewalls, track shoes, and custom structural castings. Produced to OEM drawings in alloy steel grades matched to the load, environment, and service life requirements of each application. CMM verification of critical bore positions and geometric relationships is standard for transmission components where dimensional accuracy determines load distribution and bearing life.
Drive sprockets and transmission components for mining conveyor and haulage systems are produced by forging in alloy steel with precision machining of tooth profiles and mounting interfaces. Tooth profile geometry is produced to the OEM drawing specification and verified after machining — because tooth profile accuracy determines how chain load is distributed at engagement, and therefore how quickly both the sprocket and chain wear.

How We Supply
All products are supplied to client drawings or specifications. Where a client drawing exists, that drawing is the production reference — not an approximation of it. Where a specification exists without a drawing, we work with the client’s engineering team to establish the dimensional and material definition before production begins.
First-article inspection against all drawing requirements precedes volume production for new components. Batch documentation — material certificates, heat treatment records, dimensional inspection results, NDT reports where specified — is supplied with each delivery as standard or on request, depending on the client’s quality documentation requirements.
For OEM supply relationships, we maintain drawing files, approved process records, and production tooling to support supply continuity over the equipment’s service life. Drawing revision control is applied rigorously; production always runs to the current approved revision, and revision history is retained.
For enquiries, contact our engineering team with the component drawing or specification. We respond to technical enquiries within one to two working days with a direct assessment of manufacturability, material options, and lead time — not a generic acknowledgement.
Small-batch and first-article production is supported for new component qualifications, field trials, and situations where volume commitment is not yet established. Minimum order quantities are discussed at enquiry stage based on the specific component and process route.
