FOUR-AXLED BACKHOE LOADER

Pope Design


Dual bogie axles on a traditional backhoe loader would allow for far superior traction and flotation. Having two axles at the front and another two at the rear would provide more contact on the ground to create lower ground pressure. It would also distribute the weight better, which would be especially helpful when lifting heavy loads with the loader or backhoe.

The independent bogie system ensures that all eight wheels remain on the ground at the same time. It also jolts the machine less than a single oscillating axle when going over bumps, which makes it much more stable and effective during grading operations. Another advantage of a bogie system on an articulating backhoe chassis is the longer wheelbase, which would help prevent the machine from ‘bobbing’ when driving at high speeds, especially with a load in the bucket.

And finally, the reduction in the diameter of the tires would provide better visibility of the bucket, create room for real all-wheel steering and even open up more room in the cab. Although the backhoe is rigidly mounted to the turret, the operator’s station, counterweight and the ROPS mounted to the top of this turret can rotate 360°. So when the cab is facing the backhoe, the counterweight opposes it.
