Use published widths, lengths, inclinations, D4–D9 standard dimensions and project models to identify pans, chains, sprockets, head and tail shafts, rollers, drives and drawing references.
TAKRAF heavy-duty apron feeders receive and meter large, abrasive, heavily loaded or hot materials. Overlapping pans connect to multiple heavy crawler-chain strands and run on head and tail shafts, sprockets, rollers, tensioning and drive systems. For spares, confirm inboard/outboard chains, pan design, chain pitch, width, overall length, shafts, drive, receiving zone, inclination, project/serial number, drawing revision and actual interfaces.
The current product page publishes project-based width, length and inclination ranges. The brochure also gives head-shaft dimensions for D4, D6, D7 and D9. These help identify equipment but do not establish interchangeability of pans, chains, sprockets, bearings, drives or modified parts.

| D6 | H 1,345 mm; C 773 mm; R 572 mm; length depends on application | Brochure dimensions; confirm pans, chains, sprockets, shafts and drive from drawings | Manufacturer brochure dimensions |
| D7 | H 1,520 mm; C 900 mm; R 620 mm; length depends on application | Brochure dimensions; confirm receiving zone, impact rails and pan design by project | Manufacturer brochure dimensions |
| D9 | H 1,786 mm; C 1,010 mm; R 776 mm; length depends on application | Brochure dimensions; D9 alone does not establish shaft, drive or chain interchangeability | Manufacturer brochure dimensions |
| BRF-W2-10000 | Published capacity 10,000 t/h | Apron feeder in the fully mobile crawler crushing station at Australia's Clermont coal mine; confirm project number, mobile-station interfaces, receiving arrangement and drawings | Project documented in 2009 |
Provide the full model, project/serial number, inboard or outboard chain arrangement, pan photographs, chain pitch, width, overall length, shaft/drive details, OEM drawing or general arrangement, used-part photographs and key interface dimensions. D4–D9 dimensions and BRF-W2-10000 project data cannot replace component drawings.
The wear system centres on carrying pans, their receiving surfaces, impact rails and hopper/skirt protection. The manufacturer describes welded or cast pans reinforced underneath and connected to two crawler chains. Confirm material, thickness, segmentation, hole spacing and fastening by processed material and drawings.
Carrying Pans / Flights
Welded or cast pans receive, carry and transfer material downstream. Check width, pitch, overlap direction, receiving surface, ribs, connecting holes, track bolts/square track nuts, chain arrangement and used-part wear.
Material assessment: Select pan materials by impact, abrasion, lump size, temperature, welded or cast design, forming and inspection requirements.
View the component guide →Impact Rails & Pan-Deck Protection
The manufacturer describes impact rails within the frame supporting pans under exceptional impacts. Provide the drop point, lump size, drop height, impact frequency, rail design, mounting holes, support interfaces and maintenance access.
Material assessment: Assess load-bearing and protective components by zone, considering load, impact, wear, welding, heat treatment and non-destructive testing.

Hopper, Skirtboard & Spillage-Handling Protection
Identify liners and guards at hopper discharge, skirts, side guides and spillage-handling areas. Check material flow, moisture, buildup, fall direction, hole spacing, fastening, cleaning access and adjacent conveyor interfaces.
Material assessment: Assess metal liners, wear-resistant composites and low-friction polymer liners separately by duty and installation position.
View the component guide →The manufacturer lists forged alloy-steel head and tail shafts, replaceable bolted sprocket segments, steel traction wheels, rollers, hydraulic tail tensioning and hydraulic/electromechanical drives. Confirm drive and load-bearing parts together with model, chain pitch, pans, shaft ends, housings, drive and modification records.
Head Shaft, Sprocket Hub & Replaceable Segments
The head shaft is described as forged alloy steel; sprockets comprise hubs and replaceable bolted segments. Check shaft ends and shoulders, chain pitch, tooth count, hubs, segments, fasteners, rotation and position.
Material assessment: Specify shaft, sprocket, segment and fastener materials, heat treatment, accuracy, inspection and fits from drawings and loads.
View the spare-parts catalogue →Tail Shaft, Traction Wheels & Hydraulic Take-Up
The tail shaft is forged alloy steel, with steel traction wheels secured by keys or clamping elements. Single-acting hydraulic cylinders act on the tail bearing housings to tension the chains. Provide the general arrangement, tensioning stroke, cylinder interfaces and used-part details.
Material assessment: Confirm tail shafts, traction wheels, pins, cylinders and connections by load, wear, pressure, heat treatment and inspection requirements.
View the spare-parts catalogue →Crawler Chains, Carrying Rollers & Return Rollers
Crawler chains may use split or pin-type master links. Carry and return rollers are sealed, lubricated crawler-type rollers with flange guidance. Check chain pitch, links, roller diameter, flanges, bearings, seals and inboard/outboard arrangement.
Material assessment: Assess chains, pins, rollers and bushings separately for impact, abrasion, fatigue, lubrication, corrosion and inspection requirements.
View the component guide →
Electromechanical / Hydraulic Drive, علبة التروس & Couplings
Drives may be hydraulic or electromechanical. The electromechanical option uses a planetary gearbox with an additional bevel stage and supports up to two variable-speed drives. Check motors, gearboxes, ratios, couplings, torque arms, flanges/locking assemblies, controls and rotation.
Material assessment: Gear, shaft, coupling, torque-arm and connection materials, heat treatment, accuracy, lubrication and inspection follow drawings and actual loads.
View the spare-parts catalogue →This page lists the product range, D4–D9 brochure dimensions and BRF-W2-10000 project references. Unconfirmed pan, link, sprocket, bearing or drive numbers are not treated as universal ordering references. OEM drawings, third-party references or used-part details can be matched to the complete installation.
Reference-use rules: A part-reference match requires agreement on the full model, project/serial number, chain arrangement, pans and chain pitch, position, drawing revision and physical interfaces. D4–D9 dimensional ranges and project capacities cannot replace component drawings.
Provide the full model, project or serial number, chain arrangement, pan photographs, chain pitch, width, overall length, shaft and drive details, OEM references or drawings, used-part photographs, key interfaces, materials and duty.
No. Pan pitch, chain pitch, sprocket tooth count, shafts, drives, receiving zones, modifications and drawing revisions can differ. Check installation records and physical interfaces.
Published manufacturer information describes pan-replacement areas and service layouts but does not provide a tooling list for every machine or a complete ordering table. Tooling and references are established only after matching model, project, position and drawings.
Provide the full model, project and serial numbers, chain arrangement, pans and chain pitch, receiving zone, shafts, drive, OEM drawing references, drawings, used-part photographs, materials and duty. We use these for technical advice, supplier coordination, quality control and finished-part delivery.
