Steel Cord Bucket Elevator Belt

Built for ultra-high and high-capacity vertical lifting, YUFENG Steel Cord Bucket Elevator Belt uses high-strength galvanized steel cords with enhanced transverse rigidity to provide exceptional dimensional stability under heavy tension. Its low permanent elongation helps maintain consistent bucket spacing, while the integrated rubber structure improves bolt pull-out resistance and reduces bucket falling risks, making it suitable for demanding long-height elevator systems.

Steel Cord Construction & Manufacturing Process

1. High-Tensile Steel Cord Reinforcement

All incoming materials are inspected before production. The longitudinal reinforcement uses high-toughness galvanized steel cords arranged under controlled tension, while a high-adhesion bonding system securely integrates the cords with the rubber layers. A transverse rigid fiber layer is also incorporated to improve resistance to lateral tearing, punching deformation and bucket-hole stress.

2. Controlled Vulcanization and Precision Punching

The belt is produced through segmented constant-temperature vulcanization to promote uniform bonding and reduce internal voids. A dedicated CNC punching line positions bucket holes according to customer drawings, avoiding contact with internal steel cords during processing. Each finished belt undergoes vertical tension fatigue and bucket bolt pull-out testing before shipment.

Performance Verification Under Vertical Heavy Loads

1. Low-Elongation Operation

In YUFENG’s 9-month tracking program, the steel cord structure showed substantially lower permanent elongation than conventional multi-ply fabric elevator belts. Under continuous vertical lifting, rated-load elongation remained below 0.2%, helping maintain stable bucket spacing and reducing the need for frequent tension adjustment.

2. Reduced Maintenance Requirements

Under an 80m heavy-load elevator application, conventional fabric belts required regular tension correction, while the steel cord belt remained dimensionally stable with routine inspection. The reinforced structure also reduced bucket-hole damage and bolt pull-out failures, supporting more continuous elevator operation.

Field Applications in Heavy-Duty Elevators

1. Cement Clinker Elevation

A 5000t/d cement plant used a customized heat-resistant Steel Cord Bucket Elevator Belt for a 78m clinker elevator. After 20 months of continuous operation, the belt maintained stable dimensions without significant elongation or bucket-hole damage, while maintenance downtime was reduced by 70%.

2. High-Lift Mineral Powder Conveying

For a 92m vertical mineral powder elevator in Southeast Asia, YUFENG supplied a steel cord belt with transverse tear reinforcement and customized punching. After 14 months of continuous operation, the belt remained intact without hole cracking or exposed steel cords, meeting the requirements of high-capacity vertical conveying.

3. Production Verification Support

For project evaluation, YUFENG can provide relevant belt specifications, punching layouts, production photographs and available test records. Customers can also confirm steel cord arrangement and processing details according to their elevator design requirements before bulk production.

YUFENG Steel Cord Bucket Elevator Belt Manufacturing

1. Dedicated Production and Quality Control

YUFENG specializes in Steel Cord Bucket Elevator Belt manufacturing and has more than 10 years of experience in vertical lifting belt production and export. Dedicated steel cord arrangement, rubber processing, vulcanization and CNC punching equipment supports consistent production from reinforcement layout to finished belt processing. Bucket holes are positioned according to the supplied drawings to avoid internal steel cords during punching and installation.

2. Low-Elongation Structure for High-Lift Systems

The steel cord reinforcement is designed for applications where conventional fabric elevator belts may experience excessive elongation and require frequent tension adjustment. Its low-stretch structure helps maintain bucket spacing and belt alignment during long-distance vertical lifting, making it suitable for high-height and heavy-duty elevator systems.

Technical Support for Elevator Belt Projects

1. Application-Based Specification Matching

We can recommend suitable belt construction according to lifting height, bucket load, conveying capacity, material characteristics and operating conditions. Customers can also provide elevator drawings or existing belt specifications for checking belt dimensions, steel cord arrangement and punching requirements before production.

2. Customized Punching and Factory Supply

Customized punching layouts can be produced according to bucket dimensions and fixing requirements. YUFENG supports sample orders, standard production and bulk customized supply, with technical coordination available throughout the order process to help ensure compatibility with the customer's elevator equipment.

Suitable for High-Height Vertical Conveying

1. Stable Belt Geometry During Operation

The low-elongation steel cord structure helps reduce changes in belt length during continuous operation, supporting consistent bucket positioning and reducing the frequency of manual tension adjustment. This is particularly useful for tall elevators and production lines operating for extended periods.

2. Long-Term Support for Heavy-Duty Industries

The belt is suitable for cement, mining, mineral processing, grain handling and other industries requiring high-capacity vertical material lifting. YUFENG provides technical guidance for installation and operation, together with production coordination for standard and customized orders.

Frequently Asked Questions

Q1: What are the core differences between Steel Cord Bucket Elevator Belt and ordinary fabric elevator belts? 

A1: The core gap lies in tensile carcass and deformation performance. Fabric belts adopt multi-layer canvas, with large permanent elongation after long vertical lifting, bucket spacing drifts and bolts pull out easily. YUFENG steel cord elevator belt uses dense steel cord as tensile core, elongation controlled below 0.2%, no bucket offset after long operation; the special high bolt-resistant rubber layer greatly improves anti-pull performance, fundamentally eliminating bucket falling safety hazards of vertical elevators.

Q2: Can you customize punching positions and hole sizes according to customer bucket drawings? 

A2: Yes. Our factory owns full-automatic CNC punching production line. Customers can provide bucket installation drawings, we precisely set hole spacing, hole diameter and edge distance, all punching paths avoid internal steel cords to prevent steel wire breakage during bolt installation, customized belts pass hole crack fatigue test before delivery, matching all mainstream bucket elevator models.

Q3: What regular maintenance can extend the service life of this steel cord elevator belt? 

A3: Two key daily maintenance items: regularly clean hot and abrasive residues attached to the belt surface to slow rubber aging; monthly check bucket bolt tightness and belt surface hole micro-cracks, timely replace severely worn driving rollers to reduce local impact on punching positions, effectively prolong the overall service cycle of the elevator belt.
