New Dynapac large tracked paver
The machine offers big paving capacity with low cost per tonne, says Atlas Copco
The Dynapac SD2550CS, suitable for markets here where larger-sized pavers are favoured
Why get it?
New improved dashboard improves operation
Good material flow for wide paving jobs
Atlas Copco Road Construction Equipment has launched a new large tracked asphalt paver, the Dynapac SD2550CS, suitable for markets here where larger-sized pavers are favoured. Equipped with the new Dynapac R300TVE rigid screed, the machine offers big paving capacity with low cost per tonne.
Dynapac’s R&D team has worked to improve a number of features on the new paver, focusing on the operator environment and control systems, total cost of ownership, and achieving a high quality finish. The machine is suited to combine with the Dynapac MF2500CS material feeder.
The SD2550CS is suitable for highway paving up to 14 m, with a theoretical production capacity of 1,100 t/h. Its heating system with a 60 kW generator, along with and the screed heating system ensure faster heating up to the full working width.
It features a hopper 2.6 m deep and with 15 t capacity, a 1.3 m wide material tunnel and a 500 mm diameter auger system, that ensure the smooth flow of material required while paving wide sections.
The paver is also available with a big material hopper and, when used together with the new Dynapac MF2500CS material feeder, the paving performance can be 30% higher.
The hydraulic drive system features thermostatic fan control for efficient cooling.
Big tracks with 320 mm wide track pads offer excellent grip and longer track pad life.
The machine will be launched in the Middle East with a Cummins QSB6.7 diesel engine (emission Stage IIIA), and can be equipped with fuel filling pump for addition pre-filtration of fuel before filling, improving fuel quality and engine longevity.
To improve operation, Dynapac have significantly enhanced operator comfort and control – a system it calls “Human Machine Interface”. A new dashboard is ergonomically positioned, and its design is based on recommendations from operators, with easy to understand analogue signs in a digital display. To make work easy for screed operators wearing gloves, the smart screed remote controls also have toggle switches for screed extensions and leveling cylinder function.
The easy-to-learn and operate intuitive dashboard is equipped with a camera system. This offers a 360 degree view, giving the operator even greater control over the paving job by monitoring the process on a high resolution display on the dashboard.
A number of screeds are suitable for the paver: the Dynapac V5100/6000 TVE (tamper vibration) screeds, V5100/6000TVH (high compaction) screeds as well as the Dynapac R300TVE rigid screed.
The R300TVE is a tamper vibration rigid screed with a basic width of 3 m that can be extended with mechanical extension boxes up to a maximum width of 14 m. In order to operate with variable paving width, the screed can also be offered with hydraulic extensions at the end, which are 1.3 m wide and would extend to 2.6 m maximum width. This screed is designed to offer a smooth surface finish due to its rigid construction.
