Traction belting generally consists of 3 layers of fabric reinforcement, compression-vulcanized between layers of high wear & weather resistance rubber. Belting is available cut to length or at maximum length of 100 meters.
Our traction belting is especially designed for the requirements of harvesting applications featuring:
- High tensile strength
- High traction power capacity
- High rubber tear resistance
- Weather compatibility of the rubber compounds
- High drive cam or rod pitch accuracy with good shock load absorption & recovery
- Consistent manufacturing standards
3 layers of EP 900/3 type textile forms our ‘Standard’ belting, which offers 900 N (1984 pounds) load strain per mm of belt width (900 N/mm). Such ‘Standard’ belting is normally used in all but the most extreme applications.
The following belting types are especially developed for high-load applications:
- 3 layers of EP 1200/3 fabric offers 1200 N/mm (2650 pounds/mm)
- 4 layers of EP 1200/4 fabric offers 1200 N/mm (2650 pounds/mm)
- 4 layers of EP 1600/4 fabric offers 1600 N/mm (3537 pounds/mm)
Deduct 10-12 mm from overall belt width due to rivet hole punching when calculating total load strain capacity.
Load strain capacity also relates to guidelines per joint type.
The equipment’s transmission must have a drive clutch protection to prevent over loading to the conveyors joints.
Each belt profile type relates directly to the drive type (see chapter 8, drive systems & sprockets). Belting with an upper profile (double profile belting) recesses the rod ends, reducing crop damage & rivet head wear.
Furthermore this guarantees a smoother running of the conveyor. Subject to rod diameter which influences overall rod end thickness, return/carry back rollers may be lower cost metal surface type.
‘Hydrobelt’ is especially manufactured for partial or total water submersion applications. It totally encloses the reinforcement carcass, to reduce working environment water or additive absorption, which may otherwise reduce the conveyor’s potential work life.
