Compare 13 current HAF models and historical PBRK installations by width, centre length, D3–D8 chain type, pans and liners, twin crawler chains, sprockets, rollers and tensioning spares.
This guide covers HAF installation identification, wear parts, chain drives and drawing-based manufacture. Before manufacture, confirm interfaces using the nameplate, full model, serial number, general arrangement, chain type, width, centre length, drawing or traceable used parts.
The table follows current HAZEMAG HAF technical data, grouped by feeder width. Historical PBRK is included only to identify older installations.

The numbers on the diagram correspond one to one with the rows below.
| No. | Component | Location | Applies to |
|---|---|---|---|
| 1 | Apron feeder pan | Upper load-carrying apron surface | HAF OEM apron-plate/sprocket assembly view |
| 2 | Drive sprocket | Large end sprocket on right | HAF OEM apron-plate/sprocket assembly view |
| 3 | Chain | Lower return chain run | HAF OEM apron-plate/sprocket assembly view |
Six positions are covered: carrying pans, receiving impact, side containment, head discharge, tail inlet and return-run spillage, with links to material and component guides.
Apron Pan / Feeder Pan
Each pan attaches to corresponding links on the twin crawler chains, with a carrying flange on alternate pans. Check width, pitch, overlap profile, holes, conveying direction and individual weight.
View the component guide →
Impact Plate & Support Block
Located under bin discharge to distribute large-lump impacts and protect the frame, chains and support rollers. Check drop height, coverage, orientation, supports and replacement space.
View the component guide →
Side Liner & Skirt Liner
Contain lateral spillage and protect the bin outlet and frame sidewalls. Height, segmentation, clearances, holes and overlaps vary with the bin and HAF width.
View the component guide →
Head Discharge Chute Liner
Located at the drive-end discharge transition, facing direction-change impact and high-speed sliding wear. Check discharge trajectory, segmentation, angles, fastening and adjacent-equipment interfaces.
View the component guide →
Tail Inlet Liner
At the tensioning end and bin inlet boundary, these liners protect the frame and guide material onto pans. Check flow, tensioning stroke, chain movement envelope and liner clearances.
View the component guide →
Drip Pan & Return-Side Liner
Collect residual material falling from returning pans and protect the lower structure. Check cleaning direction, outlets, segmentation, supports and safe clearance to return chains.
View the component guide →Drive and support parts are listed separately. Check links, pins and bushings, drive/tensioning sprockets, rollers, slide rails and tensioning shafts together against the HAF model and D3–D8 chain type.
Tractor Chain Link
HAF uses two crawler chains with each pan attached to the links. Check D3/D4/D5/D7/D8 type, pitch, left/right position, holes, link orientation and complete-set quantities.
View the component guide →
Chain Pin, Bushing & Retainer
Form chain articulations and withstand tension, impact and dust abrasion. Check pin diameter and length, bushings, seals, lubrication, locking method and fit clearance.
View the component guide →
Drive & Take-Up Sprocket
Each chain has a sprocket on both the drive and tensioning shafts. The drive sprocket transmits motion; the tensioning sprocket guides the chain. Check chain type, tooth profile, pitch, bore and shaft connection.
View the component guide →
Track Roller, Support Roller & Slide Rail
Support rollers carry the upper chain run; rollers under the bin may sit on heavy-duty flexible blocks. Slide rails between the chains limit pan deflection. Check roller diameter, shaft ends, spacing and mounts.
View the component guide →
Take-Up Shaft & Chain Tensioner
The tensioning station connects to the main beams and guides the tension-shaft bearings. Check stroke, side-to-side synchronization, screw or hydraulic design, housings, stops and chain preload.
View the component guide →No. Also confirm D5 chain type, pitch, left/right chain, drive or tensioning end, shaft connection, serial number and drawing. The model only narrows the search.
No. Pitch, links, pins, bushings, sprocket profiles, load ratings and interfaces can differ. Check each against the complete HAF installation records.
Provide the full model, serial number, width, centre length, inclination, D3–D8 chain type, drive or tensioning end, drawing, used-part photographs and duty. These support identification, material assessment, manufacturing coordination, quality control and finished-part delivery.
