The Dynapac SD1800W and SD1800C are wheeled and tracked versions of the same asphalt paver model, which features improved levels of operator comfort, reduced running costs and lower emission levels.

The new pavers have operating weights between 10.3 tonnes (wheeled) and 10.5 tonnes (tracked) and feature a 4.8-cubic-metre hopper and a laying capacity of 350t/h.

Both units are powered by a 2.9L 54kW Deutz diesel engine and Dynapac says they have a maximum paving speed of 25m/min and a maximum travel speed of 4km/h.

Both machines have a slidable, tiltable and height-adjustable operator console as well as load-sensing hydraulic pumps. The two pavers use Dynapac’s PaveManager 2.0 software which can automate certain paving and memory parameter functions as well as the crown and slope settings, minimising the potential for rework.

To place material, the new paver range uses Dynapac’s new V3500 screed which the company says provides ‘unequalled stability’. Dynapac’s V series screeds can double their width using the hydraulic extender.

They also use Dynapac’s safe-impact push roller system that minimises shock (and damage) to the screed from bumping the truck. Material flow is controlled by proportional sensors, ensuring smooth flow along the conveyor and minimising auger reactions to avoid material segregation.

The conveyor itself is a 700mm-wide dual-bar feeder type, controlled by paddles on the operators’ station.

The new pavers have auger widths of between 1.71m and 3.15m, have 320mm diameter cast flights and are height-adjustable to 200mm.
