Perpendicular elevator chains are engineered chains designed for vertical lifting and bucket-elevator systems. The supplied technical drawing shows multiple chain and attachment configurations, including chain plates, rollers, pins, projecting attachments, bucket or attachment plates, and section views for matching the elevator assembly.
The supplied parameter table includes five models:
12A-LK2
12A-LK1
16A-LK1
16A-LK2
216A-LU
The drawing and table include references for pitch, inner plate width, roller diameter, chain height, plate thickness, attachment spacing, pin length, section dimensions, minimum ultimate tensile strength, and weight per meter.
Key Features
Vertical Conveying Chain Structure
The drawing shows chain arrangements designed for vertical elevator equipment. The chain assembly includes repeating chain plates, rollers, pins, attachment plates, and projecting components for connecting buckets or elevator attachments.
Multiple Attachment Configurations
The technical drawing presents several views of attachment arrangements, including:
Main chain assembly
Chain and attachment section
Side attachment configuration
Projecting attachment plate view
Chain plate view with attachment projections
Attachment and pin section views
The correct attachment arrangement should be matched to the bucket layout, elevator frame, chain-wheel geometry, and equipment drawing.
Engineering Dimensions for Equipment Matching
The supplied drawing includes the following visible fields:
Blank values are preserved where the supplied source image shows no value. No missing attachment dimensions have been inferred.

Model Overview
12A-LK2 and 12A-LK1
These models use a pitch of 19.05 mm and share the main chain dimensions shown in the source table. Their attachment-related fields differ in the source data, so the correct model should be matched to the original elevator attachment arrangement.
16A-LK1 and 16A-LK2
These models use a pitch of 25.4 mm. The source table shows different attachment data for the two model forms, including a supplied g value for 16A-LK2 and a blank source field for 16A-LK1.
216A-LU
The 216A-LU model uses a pitch of 50.8 mm. Several attachment fields are blank in the source table and are intentionally retained as blank. Confirm the attachment geometry against the original equipment drawing before ordering.
Typical Applications
Public engineering references describe bucket and vertical elevator chains in applications such as:
Cement plants
Clinker and limestone conveying
Building-material production
Powder and raw-meal handling
Coal and mineral handling
Grain and agricultural bulk materials
Fertilizer and chemical bulk materials
Sand, aggregate, and abrasive solids
Continuous vertical material transfer
Chain bucket elevators
Elevator systems with projecting bucket or attachment plates
Bucket elevators convey bulk materials vertically along a production line. Chain-based systems are commonly considered where the conveyed material, temperature, particle size, density, or shock conditions require an engineered chain configuration.
Selection Guide
1. Confirm the Chain Model
Select the model based on:
Required pitch
Existing chain-wheel or sprocket
Bucket spacing
Attachment arrangement
Pin and roller dimensions
Chain length
Operating conditions
2. Match Pitch and Chain-Wheel Geometry
The supplied pitch values are:
19.05 mm
25.4 mm
50.8 mm
Pitch must match the chain-wheel tooth spacing and the complete elevator chain path.
3. Confirm Attachment Dimensions
Check the complete attachment geometry, including:
2X and 2C
N1 and N2
S, S1, S2, S3, and S4
X1, C1, 2X1, and 2C1
g and O1
L and pin/section diameters
Do not assume that two models with the same pitch have interchangeable attachments.
4. Review Vertical Elevator Conditions
Provide:
Elevator height
Chain center distance
Bucket capacity
Material bulk density
Material temperature
Particle size
Abrasiveness
Moisture and corrosion conditions
Elevator speed
Start-stop frequency
Shock loading
Chain-wheel dimensions
Lubrication method
5. Separate Strength Data from Working Load
The source table includes Ultimate Tensile Strength Min and Weight per Meter. These values should not be treated as an automatic allowable working-load rating. Final selection requires a complete engineering calculation using the actual chain tension, bucket weight, material load, speed, shock factor, fatigue considerations, and safety factor.
Cement and Building-Materials Considerations
Public industry sources identify temperature, particle size, density, abrasion, and shock loading as important factors in bucket-elevator selection. Chain bucket elevators are often considered for hot, abrasive, coarse, or dense bulk material, but the correct equipment and chain type must be confirmed by the system designer.
For cement and building-material applications, provide:
Raw meal, cement, clinker, slag, limestone, sand, or other material description
Material temperature
Maximum particle size
Bulk density
Moisture content
Required vertical capacity
Elevator height
Chain speed
Bucket spacing
Maintenance and inspection conditions
