Dynapac updates PaveManager

Dynapac has expanded its control system for optimising and managing the paving process with a range of new features.

Dynapac, a leading road construction equipment manufacturer, has expanded its PaveManager control system with several new features, further helping to optimise and control the paving process.

The main new features of the PaveManager 2.0 system are VarioSpeed; a load-sensing system for improved fuel efficiency; an automatic measurement system for continuous monitoring of the material laid; an automatic programming function for optimum end results; and a new operator interface.

The PaveManager combines easy handling through a new ergonomic dashboard with advanced paving functions. It is available for the recently introduced SD range of pavers and is suited for controlling most paving applications, from small paving to large highway projects.

According to a Dynapac spokesman, the VarioSpeed gives a significant reduction in fuel consumption, as the engine is always working at optimum load.

“Working continuously and seamlessly with other functions of the machine, VarioSpeed measures via sensors the load on hydraulic motors and adjusts the hydraulic flow. The PaveManager computer then adjusts the engine to give the optimum rpm (revolutions per minute) for the load at hand,” he explains.

PaveManager 2.0 control system has a continuously working load-sensing system offering substantially reduced fuel costs.

Compared to the traditional way of working on a constantly high rpm, this also reduces the noise level and carbon dioxide emissions as well as increases the engine life.

With the VarioSpeed, full performance is delivered at much lower engine load reducing the fuel consumption. “For an example, a paving application involving a wear coarse with a 5-m working width could go from a constantly 1,800 rpm to around 1,400 rpm offering 20 per cent fuel saving for the user,” says the spokesman.

The new “Save & Load” feature on the PaveManager 2.0 incorporates a memory function. Conveyor, auger, tamper, vibration and screed temperature settings can all be saved. This avoids costly paving mistakes and saves time every morning when setting up the paver.

The automatic measurement function shows in real time if a parameter differs from the material planned, avoiding extra cost. And with the new built-in Paving Calculator, the operator can calculate the amount of material needed from the plant to finish the job at the jobsite, thus eliminating the need to transport excess material to site.

The PaveManager 2.0 features automated paving functions where it is possible to programme functions to automatically adjust slope of the road or crowning of the road with respect to paved distance. The operator can choose from three modes for crowning: manual, automatic control or way dependent control.

The PaveManager 2.0 is controlled through an ergonomically designed dashboard and a new remote control. The easy-to-use dashboard features self-explanatory symbols, alignment of symbols due to function groups, a stable and shockproof housing and a large 6.5-inch full-colour display. The layout of the interface is based on operator usage frequency.

The system also allows for two video input sources, enabling the use of two cameras, for instance, in front of the paver or over the hopper.

 

Technology centre

Dynapac has established a reputation for its dedication to machine performance and ranks among the technology leaders in the field of soil, asphalt and rock-fill compaction, milling and paving.

The company is now aiming to become the leading partner for compaction, milling and paving applications, through its Technology and Application Centre (TAC) offering the best-performing products backed by unmatched knowledge on every level.

The TAC is located at the Dynapac machine performance testing facility in Karlskrona, Sweden.

According to manager Fredrik Akesson, one of the aims of the TAC is to raise the level of application knowledge in the infrastructure and other construction sectors. “We want to influence decision-makers, planners, and specification writers in these industries, as well as local governments, and road administration and homologation organisations,” he says.

He points out that Dynapac compaction, milling and paving know-how and solutions can be used to build strong, sustainable road networks and minimise traffic disruptions due to repair and maintenance work. “There is huge potential for achieving direct and indirect savings in time and money for everyone, including the general public,” he adds.

The TAC has indoor and outdoor test areas and a laboratory. The indoor test area has enough space to accommodate even the largest single-drum rollers, enabling full-scale testing to be performed under controlled conditions. Outdoor testing is performed from May to September to reduce the influence of the weather and thus ensure reliable results.

The TAC has a fully-equipped materials laboratory conducting ongoing research into materials and their behaviour during compaction, milling and paving.

Akesson says the TAC will initially put a lot of effort into training people in Atlas Copco customer centres around the world in machine selection and methods.

The TAC, he adds, will provide training on construction materials as well as on machine and material interaction and other issues relating to compaction, milling and paving. It will also generate tools for training – there is already a comprehensive compaction and paving manual.

For customers, the TAC will provide technical support with machine selection and methods for upcoming projects, as well as assisting with problem-solving in ongoing projects. For high-level projects and major customers, the TAC’s application expertise, resources and experience are available in the form of direct consultation and support.

As an example of how TAC’s know-how can help customers, Akesson points out that if a customer simply wants to order a 10-tonne roller for a project, there is a risk that he or she will be disappointed in the performance. “If the customer agrees, we carefully review the material to be compacted, the compaction strategy and the ground conditions in advance in order to help him/her select the correct machine for the job and get a top quality result. A better result and a lower cost per compacted cubic metre might, for instance, be achieved with an eight-tonne machine.”

Akesson says Dynapac’s product design and development department will also benefit continuously from the results of the TAC’s application research and machine performance testing activities.
