Sophisticated tooth loss detection system

Signals emitted by the GET sensors are transmitted via antennas and processed by an electronic control unit. A tablet in the machine cabin displays the GET’s live status and alerts the operator in the event of a detachment by visual and acoustic warnings.

The system is the product of a five-year development programme and MTG says that it will help reduce damage to crushers and minimise downtime, delivering major cost savings for operators. Because the system is simple, there is no need for additional training to use it.

Being able to stop the excavator quickly when a tool detaches addresses the risk from these hard components ending up in the crusher, which would otherwise cause extensive and costly damage as well as halting processing operations.

MTG says that the system is available for use on excavators weighing 250tonnes or more in Australia, Europe or the US, but will be available in more markets in due course.

Spain-based MTG produces a range of teeth systems for use with excavator and wheeled loader buckets in quarries, construction sites and mines.

The company says the GET Detection Series provides its customers with increased safety by preventing a crusher – for example, being used in a quarry – from being damaged if a GET (ground engagement tool such as excavator bucket teeth) becomes detached.

“Based on extensive laboratory bench testing and field tests, we can state that MTG’s solution detects a possible GET detachment in less than three seconds, with a very high level of reliability, preventing a subsequent fall into the crusher,” the company says.

The system uses visual and sound alerts via the display screen on a tablet in the cab, to alert excavator drivers to any teeth detachments from the bucket.

The GET Detection series includes a suite of devices compatible with MTG’s Terra cast lips, Twinmet and new Veemet tooth systems as well as Promet shrouds. The GET design of these product families enables the addition of sensors and activators to allow digital monitoring of the entire cast lip configuration.  

The signals emitted by the GET sensors are transmitted via antennas and processed by an electronic control unit. A tablet in the machine’s cabin displays the GET’s live status and alerts the operator in the event of an incident.

GET Detection has especially been developed for hydraulic excavators with an operating weight of more than 250tonnes and is so far available in Australia, Europe, and the USA. More markets will follow shortly, and new GET Systems will be compatible with the GET Detection System.

Also new from MTG is the Comet fully hammerless solution for small construction machines. This new tooth system has been especially developed for digging applications of excavators <15tonnes, mini loaders, and backhoe loaders.  

Available in sizes 5, 8, 10 and 15, the new Comet’s features are designed to give users higher productivity, maximum reliability and a longer operational life.

The third new launch from MTG is the Veemet tooth system suitable for wheeled loaders and excavators between 20-150tonnes operating in quarries, construction sites and small mines.
