Atlas Copco’s productive and innovative duplex roller
Atlas Copco says its new duplex roller has novel features including auto-braking
Atlas Copco says that its LP705 walk-behind duplex roller shares features with the recently introduced LP605 model. The LP7505 is a larger model and retains the flip-up hood seen on the LP605, which allows easy access for engine maintenance or battery charging. Of note is that the manual brakes have been replaced with new automatic hydraulic brakes; when pressure goes down, the unit brakes automatically. If pressure goes up, the brakes are released. Other features include new scrapers to avoid material adhering to the drums as well as a new hydraulic oil cooler to better control temperature in hot working environments. The hydraulic oil cooling system is of note as keeping oil temperature down lowers components wear, increases battery life and reduces stresses on seals. The firm says that the operator also has better access to throttle control, electrical starting box, water control, while the unit offers low hand and arm vibration values.
