COMPACTION SENSOR (MVH406 DSCPAS Only)

Compaction Analyzing System (COMPAS) is a system that uses an acceleration sensor to show real-time soil stiffness via LED's (light-emitting diode) turning on with each pass of the compactor.

This COMPAS improves compaction work efficiency because it can prevent an already properly compacted area from being compacted more than necessary and identify an area where more compaction is needed.

COMPAS also has a function to detect abnormalities such as vibration trouble (insufficient vibration frequency), ground trouble (soft soil) and other functional issues (Figure 21).

NOTICE

COMPAS can only show progression of the soil stiffness and is not meant to measure absolute soil density. When using COMPAS always calculate appropriate soil density by conducting proper testing such as plate load test and dynamic load test to best compliment the LED lighting progression with the actual measurement value.

Normal Compaction (Compaction Progression)

NOTICE

Not all yellow status LEDs will turn on.The progression of the yellow status LEDs depends on the type of soil being compacted. If compacting gravel (stiff soil) potentially all status LEDs will turn ON.

If compacting sand (soft soil), fewer status LED's will turn ON. Remember DO NOT over compact.

When the plate compactor is in idle mode the green LED will begin flashing and the red LED will turn on. As the engine RPM's are increased and compaction begins, the green LED will stop flashing and turn on (solid). The red LED will turn off and the #1 yellow LED will turn on. As compaction progresses the number of yellow LEDs, 2 thru 8 will turn on (Figure 22).

The number of yellow status LEDs that will turn on is soil dependent.

Normal Compaction (Compaction Limit)

The compaction limit (Figure 23) is achieved when all the yellow LED's 1 thru 8 including the red LED are all on, depending on type of soil being compacted . At this point the machine cannot compact any further. If the compaction results are not satisfactory then check and make sure the soil type, moisture content, lift and number of passes are proper for this machine.

MVH406DSCPAS, MVH406DSZ specifications

The Multiquip MVH406DSZ and MVH406DSCPAS are powerful and robust vibratory plate compactors designed for various construction and civil engineering applications. These machines are engineered to provide exceptional performance, durability, and ease of use, making them suitable for both professional contractors and DIY enthusiasts.

The MVH406DSZ model features a reliable air-cooled, four-stroke gasoline engine, delivering optimal power and efficiency. With a weight of approximately 400 pounds, it offers excellent stability while compacting soil and asphalt materials. The machine operates at a frequency of around 5,600 vibrations per minute (VPM), ensuring rapid and effective compaction across various surfaces. The heavy-duty base plate measures 24 inches in width, providing optimal coverage for large areas and enhancing productivity on the job site.

One of the standout features of the MVH406DSZ is its innovative anti-vibration technology, designed to minimize operator fatigue during extended use. This feature allows for a more comfortable operating experience, as the vibration levels are significantly reduced, enabling operators to work longer without discomfort. Moreover, the ergonomic handle is adjustable and designed for ease of maneuverability, ensuring that operators can guide the compactor effortlessly around obstacles.

On the other hand, the MVH406DSCPAS model features similar core specifications but comes equipped with additional benefits, such as the compactor’s ability to use multiple attachments for various tasks. This versatility is a key characteristic that makes the MVH406DSCPAS model particularly advantageous for contractors looking to maximize their equipment's utility on diverse jobs.

Both models are designed with durability in mind, featuring high-quality materials that can withstand the rigors of frequent use. The plates are constructed from heavy-duty steel, ensuring longevity and resistance to wear and tear. Additionally, the compactors’ easy-access maintenance points facilitate quick oil changes and routine upkeep, prolonging the equipment's life and ensuring reliable performance.

In conclusion, the Multiquip MVH406DSZ and MVH406DSCPAS compactors are exceptional choices for anyone in need of reliable and efficient compaction equipment. With their powerful engines, advanced vibration-reducing technology, and rugged design, these models are well-suited for effective operation in both small and large-scale projects. Whether you require a machine for grading, trenching, or asphalt work, the MVH406 series delivers performance and durability that you can count on.
