Why Bucket Elevator Belts Require Professional Engineering?
Suitable Materials
Key Performance Values
- Vertical Transport Efficiency: Lift materials up to 60+ meters while maintaining consistent capacity and speed without spillage.
- Space-Saving Design: Compact footprint compared to inclined conveyors, maximizing floor space utilization in your facility.
- High Capacity Handling: Proven to transport 50-500 tons per hour depending on configuration and material characteristics.

Steel Cord Option
Why EP Fabric is the Optimal Choice for Most Applications
EP (Polyester-Nylon) Advantages
- Best Cost-Performance Ratio: Delivers industrial-grade strength at lower cost than steel cord for lifts up to 50m.
- Superior Flexibility: Easily wraps around smaller diameter pulleys (300-850mm), reducing equipment costs.
- Excellent Adhesion: Stronger bond between fabric and rubber layers prevents delamination and extends belt life.
- Damage Containment: Fabric damage remains localized, preventing catastrophic belt failure during operation.
- Moisture Resistance: Synthetic fibers don't absorb water, maintaining consistent performance in humid environments.
When to Choose Steel Cord
- Extreme Lifting Heights: Required for vertical transport exceeding 60 meters where EP would need excessive plies.
- Maximum Load Capacity: Handles 500+ tons per hour with minimal elongation under continuous heavy loading.
- Lowest Elongation: Steel cords provide near-zero stretch, eliminating tracking issues on ultra-tall elevators.
- Long-Term Investment: Higher upfront cost justified by extended service life in mission-critical, high-capacity installations.
- Harsh Conditions: Superior resistance to impact and abrasion in cement plants, mining operations, and power stations.

EP Textile vs. Steel Cord: Complete Comparison
Selecting the right carcass type determines your bucket elevator's performance, maintenance requirements, and total cost of ownership. Compare key characteristics to make an informed decision based on your specific operational parameters.
EP Textile Belts
Polyester-nylon fabric construction offers excellent strength-to-weight ratio and flexibility. The standard choice for 90% of bucket elevator applications worldwide, combining proven reliability with cost-effectiveness.
- Ideal for lifting heights: 10-50 meters
- Capacity range: 50-300 tons/hour
- Polyester warp: High tensile strength, low stretch
- Nylon weft: Transverse strength, bolt holding
- Available: EP315 to EP1500 (3-7 plies)
Steel Cord Belts
Steel cable reinforcement provides maximum breaking strength with controlled elasticity. Engineered for extreme-duty applications where EP fabric limitations are exceeded, ensuring reliability in mission-critical installations.
- Ideal for lifting heights: 50-100+ meters
- Capacity range: 300-1000+ tons/hour
- Steel cord warp: Maximum strength, minimal elongation
- Optimized modulus: Balance of strength & flexibility
- Lower diameter pulleys possible vs. traditional steel
