Fabric Bucket Elevator Belts
Hongkun supplies fabric bucket elevator belts for new equipment and replacement projects. The range covers multi-ply rubberized fabric belts and PVC/PVG solid woven belts.
EP multi-ply fabric is Hongkun's main textile carcass option for bucket elevators. Other multi-ply fabric materials include CC cotton, NN nylon and polyester/cotton, subject to the application and confirmed supply specification.
Send your existing belt specification, dimensions or bucket hole drawing for a quotation. Belt construction, attachment strength and splice design are reviewed together.

Multi-Ply Fabric and Solid Woven Constructions
Fabric bucket elevator belts use two different carcass structures. Multi-ply belts combine separate rubberized fabric layers; solid woven belts use an integrated woven carcass.
Multi-Ply Rubberized Fabric Belts – EP, NN, CC and Polyester/Cotton
The fabric plies carry belt tension. Rubber between the plies bonds the layers, while outer rubber covers protect the carcass.
CC, NN, EP and polyester/cotton identify fabric materials within this multi-ply family. They are not four separate carcass structures, and CC or NN is not a subtype of EP.
| Fabric material | Yarn construction | Selection considerations for bucket elevators |
|---|---|---|
| EP polyester/nylon | Polyester warp and nylon weft | Hongkun's main multi-ply option. Low longitudinal stretch is a selection advantage; confirm working elongation, transverse support and bucket attachment strength. |
| NN nylon | Nylon warp and nylon weft | Flexible fabric with good impact resistance. Its greater stretch can require more take-up allowance; check the actual load and tensioning arrangement. |
| CC cotton | Cotton fabric | A legacy fabric option. Review its lower strength and greater stretch, and check moisture exposure before specifying it for replacement duty. |
| Polyester/cotton | Fabric combining polyester and cotton | An alternative fabric material. Confirm the yarn construction, strength and elongation rather than assuming performance midway between CC and EP. |
EP is the main option presented here, not the name of the entire multi-ply family. The required belt rating and ply count remain separate specification items.
PVC/PVG Solid Woven Belts
Solid woven belts use an integrated textile carcass rather than separate rubberized fabric plies. PVC and PVG identify cover/construction variants within this family.
PVC belts use PVC covers; PVG constructions add rubber covers over a PVC-impregnated solid woven carcass. Confirm the exact cover material and elevator-specific construction for the order.
Do not specify a solid woven belt by copying an EP ply count or rubber-cover combination. Bucket-bolt holding, working tension and splice compatibility need their own review.
Fabric Bucket Elevator Belt Specifications
Specify the carcass family first, then confirm the finished belt dimensions and operating requirements. Ordinary conveyor belt size tables do not define bucket elevator belt supply limits.
Multi-Ply Fabric Belt Specifications
| Specification item | Confirmation for the quotation |
|---|---|
| Fabric material | EP as the main option; CC, NN or polyester/cotton where specified and confirmed |
| Fabric grade and ply count | State separately; confirm the complete belt rating and allowable working tension |
| Belt width and length | To the approved elevator drawing; confirm cut length and splice allowance |
| Covers and finished thickness | Confirm top/bottom rubber covers, compound and finished belt thickness |
| Elongation and pulleys | Check elongation at the stated load, pulley diameters and available take-up travel |
Material identifiers alone do not establish the finished belt's strength or lifting capability. A change of fabric material requires a complete construction review.
PVC/PVG Solid Woven Belt Specifications
| Specification item | Confirmation for the quotation |
|---|---|
| Belt type and rating | State PVC or PVG and the required complete-belt rating |
| Belt width and length | To the approved elevator drawing; confirm cut length and splice allowance |
| Covers and finished thickness | Confirm the cover material, cover thicknesses and complete belt thickness |
| Bucket attachment and splice | Review bolt holding, hole pattern, fasteners and the compatible splice system |
| Operating and safety requirements | Confirm tension, elongation, pulley requirements and any required test documents |
PVC/PVG dimensions and ratings are confirmed for each elevator application. EP fabric grades and multi-ply size ranges do not apply to this construction.
Tensioning and Splice Review
Assess elongation at a stated load and confirm the available take-up travel for the proposed construction. Include any history of repeated shortening or tension loss.
Confirm the splice before approving the cut length and nearby bucket positions. A photo of the current connection helps with replacement review.
Details for Your Order
Send the available details below. If an item is unknown, include the equipment drawing, belt markings and photos for review.
| Parameter | Details to send |
|---|---|
| Carcass family | Multi-ply rubberized fabric or PVC/PVG solid woven |
| Fabric material or belt type | EP, NN, CC or polyester/cotton for multi-ply; PVC or PVG for solid woven |
| Strength and construction | Existing marking, required belt rating and multi-ply count where applicable |
| Belt width | Finished width in mm |
| Belt length | Required length; state whether it is cut length or installed loop length |
| Belt thickness and covers | Finished thickness, cover material and top/bottom cover thicknesses |
| Mounting holes | Drawing with diameter, center distances, bucket pitch and edge distances |
| Bucket attachment | Bucket drawing, load, bolt and washer details |
| Working tension | Elevator design value, if available |
| Pulleys and take-up | Head and boot pulley diameters, take-up type and available travel |
| Splice | Existing connection or proposed splice arrangement |
| Operating conditions | Material, temperature, belt speed and lifting height |
| Special properties | Required antistatic, flame-resistant or food-contact properties and applicable documents |
| Order details | Quantity and delivery destination |
Bucket Mounting Holes to Your Drawing
Mounting holes must match the bucket drawing and selected bolts. Show the hole diameter, cross-belt center distances, bucket pitch and edge distances on one drawing.
Identify the first bucket's position relative to the splice or belt end. Hole processing must suit the selected multi-ply or solid woven carcass.
For replacements, send photos of the bucket backs, bolts and old hole pattern. Check enlarged or damaged holes against the original dimensions before copying them.
Applications and Replacement Belts
Grain, feed, fertilizer and mineral-powder elevators need a construction selected for their material and equipment. EP is Hongkun's main multi-ply option; suitability still depends on the complete belt design.
| Application detail | Information to provide |
|---|---|
| Conveyed material | Product name, particle size, oil content or chemical exposure |
| Temperature | Normal operating temperature and short-duration peaks, if relevant |
| Elevator duty | Lifting height, belt speed, bucket size and load |
| Existing equipment | Pulley diameters, take-up arrangement and splice |
For grain and feed applications, confirm any required antistatic, flame-resistant or food-contact properties before ordering. Neither an EP designation nor a PVC/PVG label proves compliance by itself.
For a replacement, send the original marking and photos of the cut edge, holes and splice. Do not replace a multi-ply belt with solid woven construction, or vice versa, without reviewing equipment compatibility.

Frequently Asked Questions
Does EP describe every multi-ply fabric belt?
No. EP identifies polyester-warp and nylon-weft fabric. CC, NN and polyester/cotton are other fabric materials within the multi-ply family, not types of EP.
Can any fabric conveyor belt be used after drilling holes?
The proposed belt needs an application check first. Review bucket attachment strength, transverse support, working tension, pulley requirements and the splice before approving it for elevator use.
Are PVC/PVG solid woven belts specified by an EP ply count?
No. They use an integrated woven carcass. Confirm the complete belt rating, covers, bucket attachment and splice requirements separately from multi-ply fabric specifications.
