Inclined
Conveyors

Holdbacks are designed to provide protection against reverse torque runaways of inclined conveyors. Speed reducers drive the rolls that move the belt carrying the material that is conveyed.



Automatic engagement and disengagement
   
Delayed engagement produces a “no load start”
   
No slippage at full running speed
   
Controlled soft-start acceleration
   
100% efficient at rated speed
   
Standard, spring control, and deep pocket models
   
Protection against shock loads during start-up

These torsionally stiff, light weight couplings are capable of transmitting high torques at high speeds while accepting significant levels of angular, radial, and axial misalignment. They are easy to install, suitable for hostile environments, require no lubrication and feature a high torque to weight ratio. Specific designs are available which meet the customer’s exact requirements. Standard units are compliant with API 671 (American Petroleum Institute) and ATEX 94/9/EC.

No maintenance
   
Standard and reduced moment designs available
   
Capable of being torsionally tuned to suit specific machinery requirements
