New Pratt Burnerd Gripsafe gripmeter makes health and safety a thing of the past

Pratt Burnerd International, a division of 600 UK, has launched their new chuck force measurement Gripsafe gripmeter. The Gripsafe accurately measures and records chuck gripping forces within seconds.

This new, innovative product, suitable for use on all makes of chuck, has been developed to help customers comply with health and safety legislation, allowing them to ensure that their chucks remain fit for purpose.


The Gripsafe is a vital health and safety instrument. The facts are clear. If your chuck is poorly maintained, has damage or excessive wear, grip force can be seriously compromised.
This is relevant on all lathes, from manual through to full CNC lathes and turning centres, whether industrial or educational. No one can afford to ignore the loss of grip that chucks succumb to over time, which can rapidly become a hazard if not maintained and monitored regularly. Pratt Burnerd believe that the Gripsafe will prove to become a welcome tool for Health and Safety managers and lathe operators alike, who have to meet exacting safety standards.

The Gripsafe ensures reliable and accurate measurement of the gripping force being applied by the chuck under both static and rotating conditions. All that is required is to clamp the Gripsafe unit in the chuck and quickly run the tests, with instant results.

You will know immediately if your chuck needs attention or replacing.

The Gripsafe, utilising the latest WiFi communication technology and unique embedded software provides end-users with many valuable features including providing extensive data collection and analysis and storage.

The Gripsafe accurately measures static and dynamic chuck gripping forces up to 100kN per jaw at a rotational speed up to a maximum of 6000 rpm and is:

• compatible with all 3 and 2 jaw chucks
• supplied with extension rings to enable use with increased diameter chucks
• able to connect to any WiFi compatible device

Additionally, the in-built Gripsafe software provides real-time data capture incorporating all essential functions needed to conclude analysis.

Its main features include:

• Rechargeable battery with USB charging interface and battery level indicator
• No additional software is required as all application software is embedded into the Gripsafe device
• Multiple machine ‘file save’ and ‘session’ features
• Data export to .CSV file function
• Test certification print facility with automatic time and date stamping
• Automatic re-calibration reminder

The Gripsafe gripmeter can be purchased outright, or alternatively be rented for an agreed timeframe to suit individual maintenance schedules.
