The WA series Tension Release Mechanism is a Renold
sprag clutch holdback contained within a housing which
allows for the safe controlled release of tension on an
inclined belt conveyor when needed or required.

As clear extension to our other types of Tension
Release Devices and the inclusion of many Renold
Direct Mounted Sprag Clutches being used in gear
boxes, we designed the TRM-I Device to compliment
our range. Many features of this device include
automatic Torque Limiting.
Being a custom designed device there are no external
dimensions changes to your gear unit. The device is
also designed with no modifications necessary to the
gear or worm shaft, thus existing field units can be
readily converted and no special tools are required
operate them.
They are suitable for single or multiple drive
applications in the automatic mode and no lengthy
preparation time is required prior to operation in the
manual mode.
