Missing Tooth Detection
ShovelMetrics™ Missing Tooth Detection* continuously monitors shovel teeth, saving mines millions of dollars annually by preventing unplanned crusher downtime.
*US Patent # 8,411,930 / CAN Patent # 2,546,758
“Previously, personnel must enter the primary crusher to remove a missing tooth. With ShovelMetrics™, we remove people from the line of fire and maintain operational continuity.”

A Dangerous Problem
Shovel teeth have the potential to break off from the bucket during operation. Such an event often goes unnoticed by the operator, digging productivity declines and the missing tooth has the potential to make its way to downstream equipment causing further damage. Missing teeth entering and jamming a downstream crusher or conveyor belt is a very dangerous situation to rectify. Such an event results in significant time and cost implications.
ShovelMetrics™ Missing Tooth Detection features a rugged camera that overlooks the shovel bucket. Through image processing and artificial intelligence algorithms, the system detects broken or missing teeth and adapters in real-time. When this occurs, the operator is alerted through an in-cab monitor.
The monitor sends visual and audible alarms outlining which tooth is missing. In doing so, the operator knows with accuracy which truck the missing tooth is in, preventing it from reaching downstream crushers and conveyor belts.
Retrieving a tooth from a crusher is very dangerous and requires highly experienced personnel. In addition, shovels, excavators and backhoes are commonly the first equipment in the material handling process and any changes in productivity can have a domino effect on downstream processes. By carefully monitoring these shovels, excavators and backhoes, unplanned downtime and losses in productivity can be minimized. ShovelMetrics™ Missing Tooth Detection offers accurate, real-time results to prevent this dangerous and costly situation.
MetricsManager™ Pro is a centralized web-based solution designed to manage and analyze information collected directly from Motion Metrics embedded systems. MetricsManager™ Pro for ShovelMetrics™ Missing Tooth Detection allows users to:
- Monitor missing tooth events to determine the exact date, time and piece of equipment that lost a tooth.
- Generate professional reports to receive further insight and an accurate timeline of events.
- Review system performance with log frequency analysis, ensuring the system is capturing and processing images frequently.
Users can access this information in real-time from a connected laptop, tablet or smartphone, providing an overview of all Missing Tooth events across all shovels connected to MetricsManager™ Pro.

How long is the installation process?
ShovelMetrics™ Missing Tooth Detection installation and calibration takes approximately 2 days to complete.
Does the system detect adapters as well as teeth?
Yes. ShovelMetrics™ Missing Tooth Detection monitors the teeth of the shovel bucket. However, when an adapter is missing, so is the accompanying tooth and our system will detect this.
How quickly does it pay for itself?
See Missing Tooth case study
How is the operator notified?
An in-cab monitor provides an overview of shovel teeth status and provides visual and audible alarms when a tooth is broken or missing. The display lights up in yellow when a tooth is predicted missing and red when its status is confirmed.
How is the camera mounted and does it get damaged?
The camera is mounted at the top of the shovel boom and attached with a rugged, industrial strength bracket to protect it from rocks and debris.
