All States Training is able to come to you for these courses.
We are flexible and mobile to meet your training needs.
Roller Operations covers roller operations in the civil construction industry. It includes: planning and preparing; conducting machine pre-operational checks; selecting, removing and fitting attachments; operation including compacting materials to pattern and density, sealing and finishing, relocating the machine; and carrying out operator maintenance and clean up.
The duration will vary depending on your background and experience. There is a logbook that must be completed with on-the-job training, they have 7 tasks listed in the front of the logbook that must be completed a certain number of times each, the amount of times will vary depending on your level of experience. Assessment cannot be conducted until these tasks have been completed and the assessment may take from 4 to 8 hours to complete.
This course is suitable for those who wish to operate a roller within the Resources, Construction and Infrastructure industries.
Yes - participants may be required to undergo a competency test
Successful students receive a Statement of Attainment which is recognised under the Australian Qualifications Framework and a wallet sized Operator Card.
National units of competency
- RIIMPO317F - Conduct Civil Construction Roller Operations.
Load shifting (other than Forklift) equipment no longer are required to have a licence however an operator must still be deemed competent. Statement of Attainment received from completing this course is suitable.
This unit forms part of the Full Qualification RII30815 Certificate III in Civil Construction Plant Operations.
WHAT IS A ROLLER?
A roller is a self propelled or towed machine used for the primary purpose of compacting a variety of types of construction materials. It may be rubber tyred, smooth drum, padded drum or grid/open face type. A roller achieves compaction by one or a combination of the following compactive methods:
- Static weight.
Rollers come in a variety of styles with the main rollers being -
- Smooth Drum Rollers - Commonly identified as a basic roller
- Pad Foot Rollers - Rollers that are used for compaction and pulverising materials. They have a square or rectangular block attached to the drum of the roller in a pattern that enhances the ability of the roller to compact and pulverise the ground.
- Sheep Foot Rollers - Similar to the pad foot roller, but with the square or tapered blocks being set in a spiral pattern to enhance compaction.
- Vibrating Rollers - Having a vibrating roller. The drum vibrates at different speeds and frequencies to achieve greater compaction. At a half setting the vibrating s fast and achieves shallow compaction. At full setting the vibration is slower and achieves a much deeper compaction. A vibratory roller has an advantage over static rollers in that it can achieve greater compaction for the same weight machine.
- Non-Vibrating Rollers - Sometimes called static rollers. Used in a similar way as smooth drum rollers, utilising the weight of the roller to compact materials.
- Multi-Tyres Rollers - Also known as rubber tyres rollers. A roller type that is used to finish fresh asphalt to produce a trafficked finish, And to bed down the asphalt or sealed surface. Spreads the compaction across the tyres and compacts the surface by pressing down on the surface with the weight of the roller and the rolling of the tyres.
- Combination Rollers - Rollers that have a combination of roller drums, such as a grid and smooth drum combination. Often used by councils as they are able to multi-task.
- Pull Behind or Tow Behind Rollers - Are towed behind another item of machinery such as a grader or tractor. Used for multi-tasking and for keeping onsite costs down.
- Grid Rollers - Used for breaking up rocky material while compacting the materials. These rollers are usually towed behind a tractor.
