PTS intelligent machines will drive the future Completely balanced Alignment of the machine frame parallel to the road surface Stable driving performance and uniform working depth on uneven surfaces Automatic chassis alignment parallel to the pavement The proprietary PTS system not only guarantees that the working depth is maintained with maximum accuracy but also makes work as easy as possible for the operator. PTS is short for Parallel To Surface, meaning that the system automatically aligns the machine parallel to the road surface in a dynamic process: the front and rear crawler track units are lowered evenly and in parallel to each other. In addition, the 4-fold, full-floating axle that forms part of the PTS system quickly balances out any unevenness on the left or right-hand side. Overall, the operator is relieved from a significant part of his workload previously generated by the need for manual adjustments.
If one of the crawler track units hits an obstacle (such as an elevated milling edge) during the milling operation, the other three units contribute to compensating the height offset: this design ensures that height compensation occurs much more rapidly. The lifting columns are interlinked hydraulically so that any surface irregularities are compensated by all four lifting columns. The machine adheres to a course parallel to the road surface in both milling and transport mode. The optimized machine balance relieves the operator and enhances the stability of the W 200 / W 200 i. PTS additionally comprises a supporting automatic function for commencing the milling operation at the set milling depth. 22 // 23

Full utilization increases efficiency Hydraulically operated electrical generator to connect up to two lighting balloons The machine comes complete with comprehensive lighting equipment Night design: backlit control panels provide perfect working conditions at night High performance also during the night The amount of night work performed on road construction sites is continuously increasing. The W 200 / W 200 i takes account of this trend by being equipped with a comprehensive lighting package as a standard feature. That said, the equipment package by far exceeds the standard. The powerful, adjustable spotlights can be attached to various points on the machine in just a few swift moves to perfectly illuminate the entire working area. After nightfall, backlit control panels provide the operator with all required details at a single glance. Should the need arise, lighting balloons can be used for additional, extensive illumination of the construction site. Any milling job can thus be easily completed even after sunset and the W 200 / W 200 i is utilized to full capacity.
Moving on to the next job in no time Its compact dimensions ensure easy transport of the lightweight large milling machine At the flick of a switch: folding down the protective canopy hydraulically for transport purposes Removable supplementary weights enable transport of the W 200 / W 200 i also on vehicles with a low maximum permissible payload. Many countries only require a permanent one-year permit for machine transport. The folding conveyor design enables the use of shorter transport vehicles. Our range of equipment options includes conveyor support legs for machine transport on a low-bed trailer. 44 // 45
Complying with ever-stricter environmental standards The W 200 / W 200 i features environmentally friendly machine technology More than ever, it is all about keeping exhaust emissions, noise and dust away from road construction sites. Wirtgen is making every effort to develop innovative solutions with low environmental impact, and the trendsetting WIDRIVE machine management system is of key importance in this regard. Consumption-optimized speed ranges in milling mode, adjustment of the engine speed to the machine s advance rate, and temperature-controlled fan speeds contribute to protecting the environment and saving resources: diesel fuel consumption is reduced significantly, resulting in a much lower amount of pollutants affecting the environment. Not to mention that the noise level of the W 200 / W 200 i is also reduced to a minimum.
Lower fuel consumption lower environmental impact Low emissions favorable environmental balance The innovative W 200 / W 200 i merges economic and environmental aspects The engine of the W 200 complies with the specifications stipulated by exhaust emission standards EC Stage 3a / US Tier 3; the engine of the W 200i complies with those stipulated by EC Stage 3b / US Tier 4i. The efficient soundproofing of the engine compartment, elastic engine support and variable milling drum speeds all contribute to reducing noise levels. The effective VCS extraction system used to evacuate fine material particles reduces dust emission in the area of the milling drum housing. No horns, please: the stoplight system used to communicate with the truck driver replaces the commonly used loud horn, especially when working at night. 46 // 47
