Atlas roller raises operator comfort

Atlas Copco’s new LP6500 Duplex Roller has been specifically designed to offer lower vibration and machine sound levels.

ATLAS Copco says its new LP6500 Duplex Roller has lower vibrations in the handle and lower machine noise than other competitors in its category.

It says the high level of operator comfort offered by the LP6500 Duplex Roller is a direct result of Atlas Copco’s continuous focus on ergonomic design, and made the claim after a test performed by the independent technical inspection organisation TÜV Nord, where the LP6500 was compared with two similar duplex roller models from other manufacturers.

“In the vibration test, the LP6500 showed a hand-arm vibration level of only 4.14 m per second squared in the top handle, while one competing roller was measured at 7.01 m per second squared in the direction handle,” a company spokesman says: “Thus the hand-arm vibration level in the handle of the LP6500 is 2.87 m per second squared lower, which means considerably less strain on the operator during a working day.”

In the noise emission test, the LP6500 showed a sound pressure level of only 87.9 dB(A), which was more than 4 dB(A) lower than one of the competing machines, and 7 dB(A) lower than the other, he adds.

Ease of handling is also an important factor for compaction equipment in this weight class. The upright handle on the LP6500 reduces vibration and has a throttle lever that allows stepless speed control for good manoeuvrability. Hydraulic transmission eliminates the need for chains or gears and enables a compact design with smooth sides, high curb clearance and no overhang. This makes handling close to obstacles or edges easy.

The fully hydraulic LP6500 is equipped with a controlled cooling fan to help reduce the risk of unplanned stops. This can contribute to longer operation times, longer service intervals and prolonged machine lifetime.

The engine of the LP6500 has a power output of 6.8 kW and centrifugal force as high as 21 kN. The machine’s power and speed gives high compaction efficiency and cuts the time required to perform each task.

To simplify maintenance, there is an hour meter and an oil alert as standard. A rigid protection frame, with a single lifting point for easy transportation, lessens the risk of impact damage. The large corrosion-free water tank reduces the number of refill stops and serves as protection for the cooling fan.

Furthermore, the LP6500 provides high compaction efficiency on thin granular soil layers, such as sand and gravel. When compacting silt, the compaction effect depends largely on water content and the LP6500 is most effective on thin layers. On asphalt the end results are excellent and the LP6500 is well suited for smaller jobs in areas such as pavement construction or repair, narrow roads, playgrounds or parking lots.
