TWIST Chest Ascender – X-Cam

TWIST Chest Ascender – X-Cam

The TWIST rope access chest ascender incorporating X-Cam can be used to link sit and chest harnesses.   It has profile attachment points and its slimline design ensures that the TWIST sits flat against the chest of the user.   It is fitted with an ergogenic catch which allows single-handed operation.  The TWIST rope access chest ascender also has a detach ability which gives greater flexibility of use and economic replacement option.

All the materials used in the design and construction of the TWIST rope access chest ascender have been selected to provide high strength and durability needed for industrial applications.  Each TWIST chest ascender rope access device has been individually marked for traceability and all parts are visible for easy inspection and maintenance.

This chest ascender rope device with X-Cam design can be used with combination harness or with separate sit and chest harness.  When it was tested on the Tecta 11mm low stretch rope , the X-Cam ascenders were found to be 25% stronger than their most popular sharp toothed competitor, with average breaking loads up to 875 kg for X-Cams versus 535kg for the established design.   X-Cam has a more advanced tooth design than traditional cams and is more suitable for industrial applications as it does not pluck the rope therefore reduces the rate of rope wear.
