New screeds further improve paving performance for the latest Dynapac tracked pavers
Several key additions to 206 Dynapac's equipment line-up will extend the firm's machine range for the road construction market. Paving, planer and compaction lines will benefit from new machines, with president Claes Ahrengart emphasising the investment in research and development Dynapac continues to make. Six new tracked paving machines are being added to the line-up and he added, "...we have also launched a new planer range and a new asphalt roller. We will have an entire new asphalt line."
The six new tracked pavers are designed for tackling paving widths from 2-14m and include sophisticated models and more basic versions, all of which share the same basic chassis as they are built on modular lines. The sophisticated models are the SD2500C, SD2500CS, SD2550C and SD2550CS and these are equipped with PLC-based controls while the conventional models are the more basic F2500C and F2500CS pavers. These six new machines replace the earlier F121C, F141C, SD115C, SD135C, F181C and F182CS models, with general improvements to ergonomics and visibility as well as the latest low emission versions of the Cummins QSB6.7 diesel. The new pavers weigh from 18.5-19.6tonnes when fitted with screeds and the power ratings for the Cummins QSB6.7 diesel range from 110kW or 129kW in the basic F2500C and F2500CS models to 176kW or 194kW in the larger more sophisticated SD2550C or SD2550CS models. Thomas Hörnfeldt, Dynapac's vice president in charge of capital equipment said, "We're talking about six tracked pavers for widths of up to 14m and outputs to 1,100 tonnes/hour."
The company has used a great deal of customer feedback to ensure these pavers meet client needs. Hörnfeldt said, "We have been talking to a huge range of contractors to find out what we need to do." Key features include the improved material transfer with hydraulic push rollers that minimise bumping from a truck and allow all types of tipper vehicles to unload into the paver hoppers. The risk of cold spots forming in the hoppers is minimised while a large chain, wide throat and specially designed augers also help minimise the risk of material segregation. Moba paving controls are offered with the pavers, ensuring high quality performance. Visibility is improved to the hopper and screed and the operator station can be slid from one side of the deck to the other using a pushbutton control. Customers can choose gas or electric heating, with the latter offering class-leading performance for fast heat-up times according to Dynapac. The screed design is said to maximise paving quality and now offers the ability to handle crown profiles from -2.5% to +4.5%. Hörnfeldt said, "We're proud of our screeds at Dynapac. We have the stiffest screeds and we're not changing that." A wheeled version, the SD2500WS, will also be launched shortly and this will share the same engine and screed as well as other features although its maximum paving width will be slightly smaller.
At the same time, Dynapac is offering two new compact wheeled planers, the PL1000T and PL600T, which have milling widths of 1m and 600mm respectively. These are built along modular lines and weigh 13tonnes and are said to be more productive than competing machines in this size class, with more power available at the 300mm maximum cutting depths. Dynapac has designed the machines to be highly manoeuvrable with tight turning circles and the ability to operate close to walls and raised edges, which ensures they can cope with working in compact sites in urban areas. Innovative single-sided drums allow fast changes to suit varying job needs while the firm's novel parallelogram front axle design allows more accurate tracking, increases traction and reduces uneven tyre wear. Both of the machines are available in four wheeled form only and share many features with the proven PL500T and TD models as well as the PL350TD launched earlier.
In addition Dynapac will release a new compact roller range in 2011, with improved machines for the 2-4tonne class. Ease of servicing and operation with low operating noise and vibration as well as good ergonomica and visibility have been emphasised during the design of these compact compaction rollers, as the firm recognises many of the units will be sold into the rental market. Power comes from low emission Kubota diesel engines for the CC1100, CC1200 and CC1300 rollers, which weigh from 2.4-3.9tonnes. Large drum diameters increase compaction performance on soft asphalt and the machines are also available in combi-form with a single steel drum and four vibratory tyres.
