Personal Protective Equipment (PPE) Required:

Hard hat

  • CSA approved safety footwear
  • Work gloves
  • Hearing protection
  • High visibility apparel

Pre Set-Up:

  • Pre-trip the unit – engine oil, fuel, hydraulic fluid, grease points, condition of conveyor belt, conveyor support cables.
  • Ensure that hopper is empty.
  • Back unit #824 underneath the conveyor outlet.
  • Turn on and warm up engine.
  • Once engine has warmed, increase rpm and engage the auger chain/conveyor switch.  Check for proper function.
  • Disengage auger chain/conveyor, shut down engine until ready to begin the loading process.

Task procedure:

  • Use a loader or backhoe to carry asphalt from the stockpile to unit #826.
  • Asphalt must be broken up – avoid loading pieces larger than 6” in diameter.
  • Fire up engine on #826, increase rpm about halfway, and engage the auger chain/conveyor switch.  Conveyor belt should be running smoothly – if not, increase engine speed slightly.
  • If using a ground assistant, ensure that they stay clear of the loader/backhoe at all times.
  • Gently fill the hopper with asphalt.
  • Asphalt will carry up the conveyor and drop into the hot box on #824.  Monitor the level and placement of the asphalt.  Stay out from under the discharge area.
  • Breeze may blow grit from the falling asphalt; wear eye protection..
  • Shut down the conveyor and adjust position of #824 if needed during loading.
  • Fill the hot box as per operation manual for #824.
  • When hot box has been filled, shut down conveyor and turn off engine.
  • Using the ladder, reach with a hoe or rake and ensure that the side vents and door hinges on #824 are clear of asphalt.

Post Procedure:

  • Pull #824 out from under the conveyor.
  • If there is still asphalt in the hopper or on the conveyor, place loader/backhoe bucket under the conveyor discharge. Operate the conveyor until it is clear of material; turn off conveyor and shut down engine.
  • Shovel spilled asphalt out from under the auger and conveyor into loader/backhoe bucket.  Ensure that the area around the unit stays clear of debris.
  • Deposit excess asphalt back in the stockpile.
