John Deere's 460E is its largest articulated dump truck yet
Wayne Grayson | August 30, 2012
John Deere announced today the release of the 46-ton 460E, the company’s largest articulated dump truck to date and the largest ADT available in North America.
The 460E ADT joins the 370E and 410E as the latest entry in Deere’s E-Series. Deere says the 460E was designed for mining, quarry, aggregate, highway and site development applications.
Like the 370E and 410E, the 460E ADT is powered by a John Deere PowerTech™ 13.5L Interim Tier 4 engine. The 460E is powered by 481 horsepower and features a ZF transmission with a high capacity retarder, eight forward gears and four reverse gears. In addition, the new John Deere hauler axles on the 460E are designed for heavy-duty applications and include on-the-fly differential locks, outboard planetaries and each axle is independently pressure lubed and filtered. The E-Series axles use internal wet disc brakes that utilize independent cooling circuits.
“This new truck design offers contractors some serious advantages in the market, including high power-to-weight ratios, gradability, and capacity,” says Mark Oliver, Deere’s ADT product marketing engineer. “One of the biggest customer inspired enhancements are the on the fly differential locks that can be applied at any speed, manually or automatically, for improved performance in poor conditions.”
Oliver explained during a Tuesday webinar on the new truck that allowing the differential lock system to run in automatic mode simplifies operation for new operators by taking the guesswork out of using the differential locks. When ground conditions get soft and difficult, the system will automatically control the axle differential locks as well as the inter-axle differential lock all while the truck is still moving. Meanwhile, an experienced operator can still choose to manually engage the traction controls.
One feature brought up a few times during the announcement is Deere’s new Adaptive Suspension Control System which improves stability on the 460E. The new suspension system is now standard on all E-Series ADTs.
Deere incorporated a new stay-tight oscillation joint, high-suspension travel on all axles and balanced weight distribution to provide the 460E with the agility and ability to navigate hostile terrain. To minimize the risk of rollover while unloading, the dump body can be restricted from rising when the rear chassis exceeds a predetermined slope angle.
Generated from customer feedback, the 460E features ground-level servicing. The company heard from its customers that they no longer wanted “people climbing on the truck to service it.” Now all daily service including fuel fill, engine fill/dipstick, wiper washer bottle refill, air cleaner, battery disconnect, transmission dipstick and grouped grease points can be completed from the ground.
The 460E also features hydraulically-controlled fans with swing-out cooling packages on both sides of the engine to form a “cool-on-demand” system. For dusty environments, there is a reversible fan option available for simplified cooler cleanout.
Inside the 460E, a cab monitor provides an easy-to-read LCD screen with onboard diagnostics, analog/digital gauges, and vital system indicators. Two ergonomically-positioned sealed switch modules simplify operation and convenience controls. The auto shutdown feature turns off the engine after an owner-determined period of inactivity to help save fuel while reducing emissions, idle time operation, and subsequent wear on the power train and hydraulics.
The 460E features a factory-installed tire pressure monitoring sytem that alerts the operator for both high or low tire pressure conditions. The truck also features an on-board weighing system. Both of these systems can deliver alerts via Deere’s JDLink online machine monitoring serivce. JDLink just got an app that works with iPhone/iPad/Android devices so you can receive alerts on the go.
Deere says the 460E is on its way to dealers now and the company is currently accepting orders.
