possible, the cold planer should use automatic slope control to cre- ate specified profile." The typical set up of Caterpillar's Grade and Slope feature for cold planers uses more data samples than other systems, he says, pro- viding a more accurate representa- tion. Plus, cross coupling capability improves machine responsiveness, providing both surface quality and accuracy. Automatic calibration ensures consistent setup and deliv- ers optimal performance, and an intuitive operator's display makes the technology easy for crews to leverage in real-world, on-the-job conditions. Wirtgen's new Level Pro Plus grade control automatic leveling system is user-friendly and regu- lates the pre-set milling depth and inclination electronically. The com- plete system consists of combin- able sensors, a controller unit and an ergonomically designed control panel for the machine operator. This grade-and-slope control system is integrated into the ma- chine control system. The preset target milling depth is accurately controlled via robust displacement sensors located in the hydraulic cylinders, which are mounted on the side plates. All key data – including the acquisition and indication of job data – are indicated in color on the operator display in the individ- ually adjustable, multi-functional armrest. Four "favorite" buttons – which can be programmed with 15 different optional functions – have been integrated in the multi-func- tional armrest for the first time. Roadtec's SmoothMill system features integrated connections and cabling and two dual control boxes for ground personnel, each capable of controlling both sides of the machine while giving the operator (driver) a separate con- trol box. The sonic sensors scan the surface 40 times per second and produce a signal that automatically adjusts the leg tubes of the cold planer so the resulting milled sur- face will conform to spec. Ease of use comes from being able to simply plug controls into sockets (conveniently located on the outside of the machine) and from combining right and left-hand side controls into one box. Reliability has been increased by routing cables through protected areas, rather than having them exposed at the out- side. Two dual (right and left side) control boxes are supplied, one on each side of the machine. EquipmentWorld.com | January 2016 55 Untitled-5 1 12/10/15 10:21 AM
