Welded-Flat Conveyor Chain for Heavy-Duty Material Handling
Product Overview
Welded-flat conveyor chains are engineered conveyor chains with welded attachment plates designed to support, push, scrape, guide, or transfer materials through industrial conveying equipment.
The supplied technical drawing shows two welded-flat conveyor chain configurations. The upper drawing presents a welded attachment arrangement with top and side views. The lower drawing presents a second attachment arrangement with multiple mounting holes and corresponding side and profile views.
The supplied table identifies two chain models:
HGH-300-F
HGH-450-S
The technical drawing and parameter table include pitch, inner-plate width, roller diameters, pin dimensions, plate dimensions, attachment dimensions, and minimum ultimate tensile strength.
All exact numerical values in this page are transcribed from the supplied image. Public sources listed at the end are used only for general welded-steel and heavy-duty conveyor-chain application background.
Key Features
Welded Attachment Plates
The chain is shown with welded flat attachment plates that can be used as carrying, pushing, scraping, or mounting surfaces within a conveyor assembly. The attachment layout should be matched to the material path and machine structure.
Two Attachment Configurations
The supplied drawing includes an upper and a lower configuration. Their visible plate layouts, hole patterns, and dimension callouts differ. The correct configuration should be selected according to the original conveyor drawing or chain sample.
Heavy-Duty Dimensional Design
The table provides large pitch and attachment dimensions for the two listed models. These values allow equipment manufacturers and maintenance teams to compare the chain against existing sprockets, guides, shafts, and attachment supports.
Multiple Dimension References
The technical drawing identifies the following dimension symbols:
P — pitch
b1 — minimum width between inner plates
d1 — maximum roller diameter
d3 — maximum roller diameter field shown in the source table
d2 — maximum pin diameter
L — maximum pin length
H — maximum plate height
T — plate thickness
X, C, S, N, g, O, Q — attachment-related dimensions and callouts shown in the drawing/table
Suitable for Custom Conveyor Layouts
Welded-flat conveyor chains can be specified for conveyor layouts that require integrated attachments rather than a plain roller-chain conveying surface. Final selection depends on the conveyed material, load, speed, chain path, sprocket arrangement, and attachment support design.

The d3 max field for HGH-450-S is blank in the supplied image and is intentionally shown as — here. No value has been inferred.
The source table labels the final field as Ultimate tensile strength with the unit kN. This value is a tensile-strength specification, not a permissible working load. Actual working load and safety factor require a complete conveyor engineering review.

Welded-Flat Conveyor Chain | HGH-300-F and HGH-450-S
Model Information
HGH-300-F
The HGH-300-F model is listed with a 300.00 mm pitch and a 450.00 kN minimum ultimate tensile strength in the supplied table.
Its attachment dimensions include:
X: 160.00 mm
C: 100.00 mm
S: 69.00 mm
N: 170.00 mm
g: 110.00 mm
O: 19.00 mm
HGH-450-S
The HGH-450-S model is listed with a 450.00 mm pitch and a 650.00 kN minimum ultimate tensile strength in the supplied table.
Its attachment dimensions include:
X: 150.00 mm
C: 110.00 mm
S: 74.00 mm
N: 250.00 mm
g: 180.00 mm
O: 23.5 mm
The source table does not show a value for d3 max for HGH-450-S. This blank field should be confirmed with the technical drawing, supplier documentation, or an original chain sample before final engineering approval.
Typical Applications
Public information about welded-steel and heavy-duty conveyor chains indicates that this chain family is commonly considered for demanding conveying environments where the chain must move bulk materials or operate with substantial abrasion, impact, or heat exposure.
Typical application areas may include:
Heavy-duty material conveyors
Bulk-material handling equipment
Drag conveyors
Cement and clinker conveying systems
Steel-mill material handling
Scraper and flight conveyors
Industrial transfer conveyors
Aggregate and mineral handling equipment
Wood, biomass, and industrial residue conveyors
Custom conveying systems with welded attachments
The exact application of HGH-300-F or HGH-450-S must be confirmed against the equipment design. The public sources below describe general welded-steel chain applications and should not be interpreted as a certification or application guarantee for the models in the supplied image.
Selection Guide
1. Confirm the Chain Model
Select the required model based on the original chain, equipment drawing, and sprocket geometry:
HGH-300-F
HGH-450-S
2. Confirm Pitch and Sprocket Compatibility
The listed pitch values are:
HGH-300-F: 300.00 mm
HGH-450-S: 450.00 mm
Pitch must match the sprocket and the complete chain path. A chain should not be treated as interchangeable based on pitch alone.
3. Check Roller and Pin Dimensions
Confirm the following dimensions before placing a replacement order:
Roller diameter d1 max
Roller diameter d3 max, where applicable
Pin diameter d2 max
Pin length L max
Width between inner plates b1 min
For HGH-450-S, the d3 max field is blank in the supplied source table and requires separate confirmation.
4. Review the Operating Conditions
Before selecting the chain, confirm:
Conveyed material and bulk density
Material size and shape
Conveyor length and center distance
Conveyor speed
Start-stop frequency
Impact and shock loading
Incline or decline angle
Number of chain strands
Sprocket tooth count and profile
Guide and support arrangement
Dust, moisture, heat, or abrasive material exposure
Lubrication and maintenance conditions
5. Do Not Use Tensile Strength as Working Load
The table lists minimum ultimate tensile strength values of:
HGH-300-F: 450.00 kN
HGH-450-S: 650.00 kN
These values should not be used by themselves to calculate the allowable working load. The actual working load depends on the complete mechanical system, safety factor, speed, shock loading, sprocket engagement, lubrication, and operating environment.
OEM, ODM, and Replacement Support
Technical matching can be based on:
Chain model
Pitch
Roller diameter
Inner-plate width
Pin diameter and pin length
Flat attachment dimensions
Hole pattern
Attachment spacing
Chain length
Sprocket and guide arrangement
Conveyor layout
For replacement or custom inquiries, please provide an original chain sample, a clear dimensional photograph, a sprocket drawing, or the conveyor assembly drawing.
