CONEXPO CON/AGG 2017 REVIEW

When it comes to the precision and cost-efficient construction of concrete pavements and monolithic profiles, Wirtgen’s slipform pavers are right for the job. With their modular design, the machines can be configured as needed, and virtually all conceivable structures are possible, including special shapes. The SP 64i represented the new generation of slipform pavers at CONEXPO CON/AGG 2017 in Las Vegas. The SP 60 series replaces the successful SP 500 – and is said to open up new possibilities for contractors. More features than ever operate hydraulically in the SP 60 series. Thanks to a new hydraulic concept, energy is now used much more efficiently, making it available for new equipment options, for example, trimmers and a large delivery screw for offset applications, or the four swivel arms used to switch the machine from transport to working mode faster. The system starts as a basic version, and grows along with the number of modular equipment options selected. Customers save by choosing only the options they want. Likewise, the intelligent machine control systems in Wirtgen’s slipform pavers are state-of-the-art. Interfaces for the Wirtgen Group’s WIDIAG service diagnosis and New SP 60 series from Wirtgen Complete with new oscillation technology, the DD105 OSC double drum compactor from Volvo Construction Equipment has the ability to effectively compact in delicate areas, such as bridges, over pipes and close to residential areas. Fitted with the flexibility of Volvo’s oscillation technology, which eliminates vertical vibrations, the DD105 OSC offers high compaction performance while producing a non-damaging oscillation movement. Featuring a 1 680 mm wide drum with hardened, abrasion-resistant alloy steel drum shell, the DD105 OSC is powered by a D3.8 Volvo engine. In addition to the oscillation technology, adapting to different jobsites is easy. With the option of using a drum with eight amplitude settings or two, changes can be made according to the surroundings and material depth, adding further to the machine’s versatility. Selecting the amplitude most suitable for the mix conditions and thickness enables the operator to reach a higher quality of work in fewer passes. The DD105 OSC offers features that are

The SP 60 series, launched at ConExpo 2017, replaces the successful SP 500.

WITOS FleetView systems support users, as does the optional Paving Plus package. Combined with this package, the swivel arms can actively circumnavigate obstacles during the concrete paving process. The option of hydraulic rotational drives, available for all SP 60 series models, provides even better manoeuvrability. With hydraulic rotational drives, the 90° or 120° steering angle of the crawler tracks becomes a major advantage, for example when setting up the machine at a job site.

Another new development is the option of choosing between two undercarriage sizes. Why is such an option necessary? For professional concrete paving at job sites with unpaved ground, the lanes for the pavers must be stabilised ahead of time. However, the larger crawler tracks exert less contact pressure per unit area, reducing the pressure on the ground, thus giving the slipform paver the stability it needs. This in turn has a positive impact on the quality of the paving results. b

designed with the operator in mind. The open ROPS/FOPS canopy and the optional enclosed cab combine comfort, control and visibility, ensuring a productive operator environment. From the air suspension seat, the operator has a commanding view of the jobsite, as well as clear sightlines down to the drum and spray bars, enhancing

safety and rolling precision. The view of curbs and obstructions is enhanced with off-set steering, aiding precise compaction. With ergonomically-positioned controls and joystick, manoeuvrability is improved for the operator, who can rely on the Anti- Slip Control to easily load and unload the machine without damaging the pavement. b
