| 摘要： | A series of updates have been introduced for the PM620, PM622, PM820, PM822 and PM825 half-lane cold planers. The PM620 and PM622 are powered by the proven Cat C18, delivering 470kW, while the larger PM820, PM822 and PM825 are powered by a C18 engine with a twin-turbo delivering 597kW. The engines meet the Tier 4 Final/Stage V emissions requirements. One of the key upgrades is the improved LED lighting for night working. The wide-dispersion LED work lights are fitted as standard, while LED perimeter lights can also be added. Milling performance is said to be optimised due to the integrated Cat GRADE with Grade and Slope system. This system includes automated features such as obstacle jump and programmable cut transitions. The machines can also be fitted with full 3D milling capabilities. The new RM400 Rotary Mixer replaces the firms RM300 Rotary Mixer. Its redesigned drive system means that the new machine is actually 440mm shorter than its predecessor and combined with its steering modes, this allows for improved manoeuvrability. The machine delivers a 2.4m cutting width, weighs in at 23.5tonnes and offers better performance both for full-depth reclamation and soil stabilisation applications. |
