• Coal Excavation

  OB Excavation

• Operator frequently checks AHT que & cusp point to reduce spot times and distance’s.

• The operator calls AHT from the que point to the cusp point during loading cycle to minimize truck exchange time

• Hang Queue time average for the shift of 35 seconds or less.

• Bucket cycle under 25-30 sec.

• Set next AHT spot point without loss of time

• Operator ensures advanced notification of relocation or impending delays.

• Maintain efficient load profile and distribution on trucks

• Monitor payload to ensure site target is met whilst truck is loaded to contain to avoid spillage

• The load unit operator removes all spot points prior to exiting the cabin of the excavator, and ensure excavator operator locks AMA zone before exiting excavator cabin

• For each criteria in this Field Verification provide a score from 1 - 5 to indicate the Field Officer's level of proficiency. The scoring system is as follows:

• 1. Not yet trained/does not understand the task/skill.

• 2. Has basic understanding of the task, but doesn’t always recognise when task needs to be performed, or cannot to perform the task without assistance.

• 3. Mostly understands the task but still requires further coaching to operate at the required level. Performs the task when required.

• 4. Competent – understands the task and completes it every time.

• 5. Has mastered the skill, could be considered an expert.
