LoadMetricsTM
The Dynamic Arm Geometry & Payload Monitoring System
LoadMetricsTM is a real-time hydraulic shovel arm geometry and payload monitoring system.
The LoadMetricsTM system monitors various shovel parameters to determine the exact payload and coordinates of each bucket load.
The system helps to increase production efficiency and to reduce equipment wear and damage.

Payload Monitoring
Dynamic payload monitoring allows the bucket-by-bucket payload of large hydraulic shovels and excavators to be evaluated in real-time and displayed on a user-friendly graphical interface. The resulting shovel payload is given with an average error of less than 2.5% and is displayed along with the accumulated payload on the truck.

Increase Efficiency
Real-time payload monitoring helps to prevent under-loading which results in efficient use of the mining equipment. Haul truck loading can be optimized and production efficiency can be increased.

Prevent Equipment Damage
Payload data is useful in assisting the shovel operator to avoid overloading the haul truck. Overloading can result in broken haul truck axles and premature wear of the haul truck tires.

Cutting Force Monitoring
An arrow, shown in the user interface, indicates the direction of the force being applied on the bucket and a color gauge indicates the magnitude of the force. This information is easily visible to the shovel operator and can be used to prevent overstressing the shovel components.

Precise Bucket Positioning
The bucket position can be estimated with an accuracy of better than 5 cm, relative to the shovel cab, for large mining shovels. This information can be used in conjunction with the mine dispatch system to provide the precise location of the material being dug and for updating the bench layout.

Cylinder Limit Indication
When nearing the shovel cylinder extension or retraction limits, the color of the cylinder, displayed on the touch screen monitor, changes to red. This provides the operator with a visual warning and serves to extend the lifetime of the shovel.

What is LoadMetricsTM?
LoadMetricsTM is a real-time hydraulic shovel arm geometry and payload monitoring system. The LoadMetricsTM system monitors various shovel parameters to determine the exact payload and coordinates of each bucket load. The system helps to increase production efficiency and reduce equipment wear and damage.
How can you/your mine benefit from LoadMetricsTM?
- Increases production efficiency and reduce the gas usage: With the real-time, bucket-by-bucket payload monitoring system, the shovel operator is able to determine the dynamic load of the haul truck and load it accordingly. As a result, production efficiency is increased by reducing the number of under-loaded trucks, thereby also reducing the number of truck runs and reducing the gas usage.
- Increases digging accuracy and effectiveness: The real-time shovel arm geometry is displayed to the shovel operator graphically. Arm geometry information is used in combination with the mine dispatch system to give the precise location of the material being dug and can also be used for updating the bench layout.
- Extends the life of the shovel and reduces down-time: The color of each cylinder near full retraction or full extension changes to red. This feature is called cylinder limit indicator and helps to prevent overstressing the hydraulic cylinders on a shovel.
- Extends the life of the haul trucks and haul truck tires: The dynamic accumulated haul truck load in conjunction with the bucket-by-bucket payload monitoring, prevents the shovel operator from overloading the haul truck, thereby, reducing the occurrence of blown or prematurely worn haul truck tires and broken haul truck axles.
- Prevents excessive usage of the shovel and determines the hardness of the mined material: The dynamic shovel cutting force is displayed in real-time, indicating the direction and the magnitude of the force applied by the shovel bucket. This feature helps to prevent overstressing the shovel components and can be used as an indicator of the effectiveness of the blasting procedure.
In addition, LoadMetricsTM system can provide the following key performance indicators (KPIs) from the data that it logs during operation:
- Dump Efficiency (DE) indicator: Based on the statistical information that Motion Metrics gathers from its international installations, it is known how much one particular shovel can dump per shift for a particular type of ore. The LoadMetricsTM system uses this information to compute the DE indicator.
- Machine Operation Health Efficiency (MOHE) indicator: The health of a shovel depends on how efficiently and effectively an operator uses the machine during the operation. If operator overloads the bucket, over extends, over retracts the cylinders, or hits the ground with excessive force, he/she can potentially damage the shovel. The damage can range from a broken stick to a burst hydraulic pipe. In either case, the downtime to fix these problems is significant and costly.
- Ore Hardness (OH) indicator: The LoadMetricsTM sensors can provide joint angles, joint positions, joint velocities, and joint torques. This collection of these inputs is used to compute actuator power (AP), power at the tip of the bucket (PB), and the cutting force. Cutting force magnitude as well as AP and PB can serve as valuable feedback tools for the blast engineers.
Why is LoadMetricsTM the best solution?
- The LoadMetricsTM system provides bucket-by-bucket payload from the shovel as opposed to haul truck load weighing systems. With bucket-by-bucket payload monitoring, haul truck overloading can be prevented, thus, eliminating blown tires and broken haul truck axles.
- The LoadMetricsTM system improves operation efficiency and effectiveness by maximizing the payload of each bucket
- The LoadMetricsTM system reduces operation costs by avoiding shovel downtime caused by overstressing the hydraulic cylinders on the shovel
- The LoadMetricsTM system accurately senses the shovel payload with an average error of less than 2.5% and displays it together with the accumulated payload on the haul truck.
How does LoadMetricsTM work?
The shovel joint angles are sensed in real-time using environmentally sealed, capacitive accelerometer pairs. The bucket position is then estimated with an accuracy of better than 5cm, relative to the shovel cab, for large mining shovels. The shovel geometry is instantly displayed on a computer generated shovel model. This information can be used in combination with the mine dispatch system to provide the precise location of the material being dug and for updating the bench layout. The shovel geometry is also used to determine if the shovel is nearing the cylinder extension or retraction limits. When nearing the shovel cylinder limits, the color of each cylinder, displayed on the touch screen monitor, changes to red.
Using the information from the pressure sensors installed on the shovel's hydraulic cylinders in addition to the shovel geometry, the dynamic bucket payload of the shovel can be determined in real-time. The LoadMetricsTM system accurately senses the shovel payload with an average error of less than 2.5% and displays it together with the accumulated payload on the truck.
The LoadMetricsTM system has been installed in mines all across the globe and is in operation on Terex RH200, Terex RH340, Terex RH400, and Komatsu PC8000 hydraulic shovels.
