Engineering welded chains are engineered chains for demanding conveyor, elevator, and bulk-material handling systems. The supplied technical drawing shows a Cranked-Link Welded Steel Chain with welded crank sidebars, rollers, pins, chain plates, and dimensional references for chain pitch and side-clearance design.
The supplied page includes two specification tables:
Main dimensional table — pitch, roller/side components, chain dimensions, and link spacing
Secondary dimensional and strength table — sidebar dimensions, plate thickness, U.T.S., and A.T.S.
The supplied models are:
W78
W82
W106
W111
W124
W124H
W132
All exact numerical values in this product page are transcribed from the supplied image. Public sources are used only for general engineering-chain applications and selection background.
The source drawing prints the English heading as “Cramked-Link Welded Steel Chain.” The phrase is preserved in the technical drawing image. The product-page title uses the conventional spelling “Cranked-Link Welded Steel Chain.”
Key Features
Cranked-Link Welded Steel Construction
The drawing shows a welded crank-link profile with repeating upper and lower sidebars connected around rollers and pins. This arrangement is designed for integration into engineered conveying equipment and chain-driven material-handling systems.
Engineering Dimensions for Equipment Matching
The technical drawing includes visible references for:
P — pitch
h2 — chain-plate height in the top view
l1 and l2 — link or sidebar reference dimensions
d1, d2, and d3 — diameter references
b1, b2, b3, b4, b5, and b6 — sidebar and assembly dimensions
T — plate-thickness reference
Multiple Chain Sizes
The supplied tables cover seven chain models with pitch values from 66.27 mm to 153.67 mm. This range supports different equipment layouts, sprocket sizes, chain widths, and load requirements.
Separate Dimensional and Strength References
The first table provides the main chain dimensions. The second table provides additional sidebar dimensions, plate thickness, U.T.S., and A.T.S. Keeping the two tables separate follows the original source layout and helps match the drawing to a technical purchase specification.

Secondary Table Field Notes
b2 max, b3 min, b4 max, b5 max, and b6 max are additional sidebar and assembly dimensions shown in the source table.
T is the plate-thickness field shown in the source table.
U.T.S. and A.T.S. are the strength fields shown in the source table.
All dimensional fields are in mm; U.T.S. and A.T.S. are in kN.
U.T.S. and A.T.S. are source-table fields. They should not be treated as an automatic allowable working-load rating. Final selection requires a complete engineering calculation with safety factor, speed, shock loading, fatigue, sprocket design, lubrication, and operating environment.
Technical Drawing
Engineering Welded Chain | W78 to W132 Cranked-Link Chain
Typical Applications
Public engineering-chain references describe welded steel and cranked-link chains in applications such as:
Drag conveyors
Apron conveyors
Bucket elevators
Bulk-material handling systems
Wood-processing equipment
Grain-processing machinery
Oil-processing equipment
Pulp and paper machinery
Board-mill and panel-processing lines
Industrial transfer conveyors
Heavy-duty material-handling equipment
Welded chains are typically considered where the conveyor or drive system requires an engineered chain arrangement for demanding handling conditions. The suitable chain model depends on the conveyed material, chain speed, pitch, sprocket design, impact level, environmental contamination, lubrication, and maintenance access.
OEM / ODM and Custom Engineering Support
Custom review can be based on:
W-series chain model
Required pitch
Chain length
Sprocket or chain-wheel drawing
Roller and pin dimensions
Sidebar dimensions b1 to b6
Link dimensions l1 and l2
Plate thickness T
Required U.T.S. and A.T.S. reference
