Measure Up Guidelines

This section describes guidelines for acquiring accurate measurements from the machine. Failure to make accurate measurements could adversely affect machine performance or result in safety hazards.

  • Move the machine to level ground that is outside the normal working area of the mine and away from other operating machines.

  • Accuracy to ± 10.0 cm (± 3.93 inch) is required.

  • When using the GPS rover device, no measurements can be taken while the machine is next to buildings, or other obstructions that may result in GPS signal degradation. Large vehicles such as Large Mining Trucks can also cause signal degradation.

  • When using the GPS rover device, the device is required to be plumb and level before recording measurements.

  • When measuring Machine Width, measure at the widest points of the machine, including all attachments to the machine (such as mirrors, stabilizers, and other such attachments).

  • When measuring Machine Length, all implements are to be extended to the furthest reach. Include all attachments to the machine when measuring (such as chucks, stabilizers, buckets, and other such attachments).

  • For points that cannot be measured using the GPS rover device directly (such as the center of the rear differential), use a plumb bob to transfer the point to the ground. Mark the spot on the ground with a wooden stake. Move the machine out of the way then measure the point using the GPS rover device.

Measuring Linear Machines

This section describes the dimensions that are needed for Linear Machines. This section applies to but is not limited to Mining Trucks, Light Vehicles, and any other machines that operate in a linear method.

Perform the following procedures to populate Table 3:

Note: Before measuring the machine, move the machine to level ground away from other working machines. Working at heights may be necessary to access parts of the machine. Make sure that there are no obstructions nearby that may hinder the operation of the GPS rover device.

Note: Autonomous Mining Trucks (AMTs) have predefined value requirements and should not use the standard measure up procedure.

Note: Autonomous Mining Trucks (AMTs) may have additional width or length given the application of special mirrors, custom bodies, and so on. The additional width must also be entered in the site configuration utility for the respective machines.

------ WARNING! ------

Inaccurate measurement of a machine (including light vehicles) can result in performance and safety degradation. Personal injury or death can result.

Measurements smaller than the machine will result in the positioning system being unaware of extruding portions of the machines. This could result in physical contact between machines. Dimensions larger than the actual machine dimensions will result in blockage and false perceptions by the autonomous positioning and perception systems. This will result in improper stoppages and truck redirections.

To avoid these and other situations, ensure that this measure up procedure and verification procedure are performed accurately.

Measuring Articulated Machines

This section describes the dimensions that are needed for Articulated Machines. This section applies to Wheel Loaders, Articulated Trucks, Motor Graders, and any other machines that have a point of articulation. Articulated Machine dimensions need to account for the complete range of articulation.

Perform the following procedure to populate Table 5.

Note: Before measuring the machine, move the machine to level ground away from other working machines. Working at heights may be necessary to access parts of the machine. Make sure that there are no obstructions nearby that may hinder the operation of the GPS rover device.

------ WARNING! ------

Inaccurate measurement of a machine (including light vehicles) can result in performance and safety degradation. Personal injury or death can result.

Measurements smaller than the machine will result in the positioning system being unaware of extruding portions of the machines. This could result in physical contact between machines. Dimensions larger than the actual machine dimensions will result in blockage and false perceptions by the autonomous positioning and perception systems. This will result in improper stoppages and truck redirections.

To avoid these and other situations, ensure that this measure up procedure and verification procedure are performed accurately.



NOTICE

If the body area polygon does not cover all parts of the machine, there is potential for part of the machine to be viewed as an obstacle by an AMT and may cause an AMT to stop or slow down. This could also result in physical contact between machines. If using this alternative body area polygon, ensure that machine operators are aware of these limitations.

Articulated Machine Body and Avoidance Area

Perform the following procedure to populate Table 7.

  1. Ensure that all implements, such as buckets, are centered and extended to the full reach.


    Illustration 11g06292860
    Front and rear articulating lengths
    (3) Machine origin
    (H) Body area back length
    (J) Body area front length

  2. Locate the machine left rear point and the machine right rear point. These points are the points that are located the farthest rear and farthest left (or right) on the machine, for example the left rear corner of the rear bumper. Refer to Illustration 11.

  3. Measure the distance between the machine origin and the machine left rear point. Measure the distance between the machine origin and the machine right rear point. Use the larger of these two values as the body area back length (H). Refer to Illustration 11. Record this value in Table 6.

  4. Locate the machine left front point and the machine right front point. Refer to Illustration 11.

    Note: For Wheel Loaders, this point will be the front left and right corners of the wheels.

    Note: For Motor Graders, the body area must consider the range of articulation for the machine, the extension of the mould board, and articulation of the front wheels. Each new operation is advised to review the normal operating configuration of the motor graders to determine the typical ranges of articulation used when transporting or when operating alongside autonomous equipment. Machine dimensions should be established based on normal operating configurations and care must be taken to not allow the operation of autonomous equipment near any equipment not operating within the configuration that was used to establish these machine awareness boundaries.

  5. Measure the distance between the machine origin and the machine left front point. Measure the distance between the machine origin and the machine right front point. Use the larger of these tow values as the body area front length. Refer to Illustration 11. Record this value in Table 6.

  6. Articulate the machine fully to the right.


    Illustration 12g06292867
    Articulating machine body area width
    (5) Machine center line
    (6) Full right articulation point
    (K) Body area right length

  7. Measure the distance along the Y-axis between the machine center line and the full right articulation point from step 6. Add 0.5 m (1.64 ft) to this value. Refer to Illustration 12. This dimension will be used for the body area right length (K) and body area left length. Record these values in Table 6.


    Illustration 13g06292868
    Articulated machine avoidance area
    (L) Avoidance area back length
    (M) Avoidance area left length
    (N) Avoidance area right length
    (P) Avoidance area front length

  8. For articulated loading tools, reducing the body area polygon size to reduce nuisance alarms while loading may be desirable. Using a smaller body area polygon may also allow the machine to work in a tighter loading area without negatively affecting production. It is important that the operator station and all access and egress points of the machine remain covered by the body polygon. This procedure may be used as an alternative to the standard body and avoidance area measurements for articulated loading machines. This process is similar to the process for measuring a linear machine.

    Note: For this procedure, the steps for measuring an Articulated machine must still be performed to determine the correct size for the avoidance area. The values from Table 6 will be used with the values obtained during this procedure.

    Note: MineStar does not have fields for Minimum Body Area Length. The values from Table 7 will be entered into MineStar in the Body Area fields.

    1. Measure the minimum body area left length (A). Refer to Illustration 14. This dimension is the distance from the machine origin Y coordinate to a point that is perpendicular to the left-most point of the egress or operator enclosure location. Add a 0.5 m (1.64 ft) buffer to the minimum body area left length. Record these values in Table 7.

    2. Measure the minimum body area right length (B). Refer to Illustration 14. This dimension is the distance from the machine origin Y coordinate to a point that is perpendicular to the right-most point of the egress or operator enclosure location. Add a 0.5 m (1.64 ft) buffer to the minimum body area right length. Record these values in Table 7.

    3. Measure the minimum body area back length (C). Refer to Illustration 14. This dimension is the distance from the machine origin X coordinate to a point that is perpendicular to the rear-most of the egress or operator enclosure location. Add a 0.5 m (1.64 ft) buffer to the minimum body area back length. Record these values in Table 7.

    4. Measure the minimum body area front length. Refer to Illustration 14. This dimension is the distance from the machine origin X coordinate to a point that is perpendicular to the front-most of the egress or operator enclosure location. This dimension must include any egress catwalks in front of the cab enclosure. Add a 0.5 m (1.64 ft) buffer to the minimum body area front length. Record these values in Table 7.

      Note: If the front-most of the egress or operator enclosure location is behind the machine origin, this dimension will be a negative number.



    Illustration 14g03725274
    Minimum body area

  9. For avoidance area lengths, use 2.0 m (6.56 ft) for all sides. Refer to Illustration 13. Record the values in Table 6.


    Illustration 15g03725301
    Avoidance area with minimum body area
    (9) Minimum body area
    (10) Avoidance area
    (11) Standard body area

  10. For Articulating Loading Tools, the use of the minimum body area adjusts the avoidance area dimensions. Follow this step to define the adjusted avoidance area dimensions for an Articulating Loading tool.

    1. For the left avoidance area, take the left body length minus the left minimum body length. This number plus the standard 2.0 m (6.56 ft) will be the left avoidance area. Record these values in Table 7.

    2. For the right avoidance area, take the right body length minus the right minimum body length. This number plus the standard 2.0 m (6.56 ft) will be the right avoidance area. Record these values in Table 7

Measuring Single Antenna Rotational Machines

This section describes the dimensions that are needed for Rotational Machines. This section applies to Excavators, Shovels, Draglines, and any other machines that operate in a rotational manner.

Perform the following procedure to populate Table 8.

Note: Before measuring the machine, move the machine to level ground away from other working machines. Working at heights may be necessary to access parts of the machine. Make sure that there are no obstructions nearby that may hinder the operation of the GPS rover device.

------ WARNING! ------

Inaccurate measurement of a machine (including light vehicles) can result in performance and safety degradation. Personal injury or death can result.

Measurements smaller than the machine will result in the positioning system being unaware of extruding portions of the machines. This could result in physical contact between machines. Dimensions larger than the actual machine dimensions will result in blockage and false perceptions by the autonomous positioning and perception systems. This will result in improper stoppages and truck redirections.

To avoid these and other situations, ensure that this measure up procedure and verification procedure are performed accurately.


  1. Straighten the machine so that the boom is parallel with the tracks.

    (A) Machine width
    (B) Machine origin Y coordinate
    (C) Machine origin X coordinate
    (D) GPS antenna X
    (E) Machine length

  2. Locate the right rear corner of the machine. This point is the point that extends from the right-most point of the machine along the X-axis and from the rear-most point of the machine along the Y-axis. All other dimensions of the machine will be based from this point. Mark the location of the right rear corner on the ground using a stake.

  3. Extend any buckets or implements to the farthest reach. Measure the machine length. This dimension is the distance from rear-most point of the machine to the front-most point on the machine, including any bumpers, hitches, or other additions to the machine, including customer or dealer attachments. Record this value in Table 8.

  4. Measure the machine width. This dimension is the widest length of the overall machine, including mirrors or any additions to the machine. Record this value in Table 8.

  5. Measure the machine origin X coordinate and the machine origin Y coordinate in relation to the right rear corner. Typically for rotational machines this point will be the center of the rotation. Refer to Table 1 for standard machine origin locations. Record these values in Table 8.

  6. For machines where the machine origin is NOT the center of rotation, measure the center of rotation X coordinate and the center of rotation Y coordinate in relation to the right rear corner. Typically for rotational machines, the machine origin is the center of the rotation.

  7. Measure the GPS Antenna X and GPS Antenna Y position in relation to the Machine Origin. For a dual antenna system, these values will be based on the primary (master) GPS antenna. For a single antenna system, the antenna should be at the center of rotation. Record these values in Table 8.

    Note: These values may be entered as positive (+) or negative (-) values. If the GPS antenna is located in front of the machine origin, the X value will be positive (+). If the GPS antenna is located behind the machine origin, the X value will be negative (-). Likewise, if the GPS antenna is located to the left of the machine origin, the Y-value will be positive (+). If the GPS antenna is located to the right of the machine origin, the Y value will be negative (-). Refer to Illustration 3.

    (F) GPS Antenna Z (Offset)

  8. Measure the GPS antenna Z position in relation to the ground level. This measurement should be from the center of phase. Record this value in Table 8.

    Note: This value is used for any machine running Detect Proximity Awareness. This value is not entered directly into Cat MineStar System.

    Note: The center of phase can be found on the specification documentation for the antenna. For the MS992, the center of phase is where the yellow meets the white on the plastic casing.

    (J) Distance to furthest point
    (K) Distance to further edge of implement
    (L) Body Area
    (M) Lane planning avoidance area
    (N) Avoidance area

  9. Measure the distance from the center of rotation to the outer corner of the operator station (H) and the furthest access or egress point. Refer to Illustration 18. Take the larger of these values and add a buffer of 0.5 m (1.64 ft) to this measurement. This dimension will be the body area radius. Record this value in Table 8.

  10. Determine the nearest proximity that a lane may be relative to the center of rotation of the loading unit. This value should be established based on the worst case truck dimension given the compatible hauler classes.In normal spotting orientations, this value should keep the body of the rotational machine out of the lane established on behalf of the spot being requested.This dimension only applicable to rotational machines that can spot and load AMTs. This dimension will be the lane planning avoidance radius. Record this value in Table 8.

    Note: For machines with a circular body polygon, this dimensional value should not be less than the body area radius.This parameter is intended to provide a buffer between the body and lane to prevent planning lanes with the body inside while in the loading position.

  11. Measure the distance from the center of rotation to the end of the longest implement, fully extended boom, shovel, or bucket. Add a buffer of 2.0 m (6.56 ft) to this measurement. This dimension will be the avoidance area radius. Record this value in Table 8.
