Application as

• Backstop

for continuous conveyor installations with multiple drives in which each drive is equipped with a backstop.
 
Features

Integrated Freewheels FXR … are sprag free­wheels without bearing support and with sprag lift-off X. They consist of the Integrated Freewheels FXM with additional torque limiter. For reversing operation, they can be optionally equipped with a reverse running function. This allows the conveyor belt to run backwards, for example during maintenance work.
The sprag lift-off X ensures a wear-free free­wheeling operation when the inner ring ­rotates at high speed.

Advantages

• Protection of gearboxes from overload by unequal load distribution in multiple drives
• Protection of gearboxes from dynamic peak torques during the locking process
• Smaller gearboxes can be used without ­negatively effecting the safety
• Protection of the backstops, as dynamic peak torques are reduced by temporarily slipping
