Wheel Loader Operator Drops Huge Stone into Empty Dump Truck

Loading a dump truck with dirt or gravel is a pretty straightforward process. Loading a truck with huge stones, on the other hand, is much more difficult because it could end up damaging the dump truck. In this case, a Caterpillar wheel loader is dropping a huge stone over a dump truck rail from about 4 or 5 feet up. The stone is probably 1,000 pounds or more, so you can imagine the kind of impact that would make on an empty truck bed from that high up.

The Powerful CAT 966M XE Wheel Loader

With this particular loader—a CAT wheel loader that looks to be a 966M XE or close to it—there really isn’t a way to avoid just dropping the large stone from a few feet up. This machine’s lift arm clearance is just under 12 feet high, which isn’t much taller than the dump truck. The loader has no problem lifting up that heavy boulder with its powerful hydraulic system and heavy-duty bucket, but it’s not able to “reach” into the dump truck like an excavator would be able to.

While not quite as versatile as an excavator, front end loaders like this one offer tremendous power. For example, the 966M XE is rated at 39,000 lbf of breakout force. Here are a few of its other impressive specs:

• 298 horsepower and 1,275 lbf-ft. of torque
• 24.4 maximum miles per hour
• 1.4 second dump speed at max height
• Total hydraulic cycle time of 10 seconds

Some Standard Dump Truck Weights and Features

This Caterpillar loader weighs about 50,000 pounds, which would be roughly the gross vehicle weight of the dump truck. The chassis of this dump truck would likely weigh about 15,000 pounds. A standard dump truck has 1 front axle and 1 or 2 rear axles. While rear axles are almost always powered in the US, they are typically unpowered in Europe. The benefit of a powered axle is that it can be lowered to provide extra support for bigger loads. A powered axle would help to cushion some of the blow of the falling stone in this case.
