Western Star Truck Sales announced the availability of the new Allison 4700RDS 2nd reverse transmission for construction applications. The company says the new transmission is ideal for mixer and dump applications offering a second, “deep reverse” in addition to the standard reverse to provide greater control and engine braking during operation on steep grades. And with a mechanical ratio of 17.12, a vehicle in 2ndreverse will have a slow creep capability with high engine speeds, making up- and downhill reversing both easier and safer.
The 2nd reverse transmission also will enable increased maneuverability for trucks operating in confined spaces, resulting in quicker operation cycles and enhanced productivity. And specifically for the mixer application, the 2nd reverse feature allows trucks to creep in reverse while pouring concrete and maintaining adequate barrel speed. 2nd reverse is available to order now.
