The 797B is mechanical drive with a power shift transmission having 7 forward gears and 1 in reverse. You can select 7th and the truck will automatically shift up and down in response to ground speed and load. There are definitely times when an operator needs to select a specific gears for certain conditions. Caterpillar continues to add features that strive to make gearing more idiot proof but it is not quite there yet. The 797 is a fantastic truck to operate. Nothing else comes close.

Guys loading like that are not the owner of the equipment. Sad to see. 2 buckets less or more and you save repaire time and money, you making more money to load a "normal" load. (sorry for my bad typing) Regards from Sweden.

@pellenyberg That load is a bit forward of center, but that doesn't mean it's overloaded. Some material will spill onto the canopy when it is that light, and that is a very small amount on the canopy compared to some trucks that get loaded. I don't know why you are even directing this at me, since I made no mention of any material on the canopy or the load being centered, I simply said that the truck is not overloaded.

@pellenyberg Wow, angry much? I'm from Canada, and I use Metric every day, so I know how it works. We still use the Imperial system for weights on the trucks, I don't know why, but we do.

I'm curious as to how you figure I know nothing about loading trucks? I would be willing to bet you've never loaded that material onto a 797. In fact, it's pretty likely that you've never even seen a 797 in person. I run a shovel and load them every day, with that same material, so I know what it weighs

@godackgudalach1 The original 797s were rated for 360 tons, the versions that followed were rated at 380, 390 and then 395 tons depending on how they were outfitted. So it's very possible that the generation of trucks you have been around were 380 ton, and you guys were following that as a guide. I know the material on that truck quite well. That's KCa, which is quite light. So that load would likely run right around 395 to 405 tons.

@msjvista way to talk shit a komatsu 930 is way better

He that's Steve he worked at site lol

[godackgudalach1]

Ohh man i guess im to conservative for everyone. Most the mines i work at we load the 797 at 380 to save the tires and the frames. But who knows how dense that material is. 793 trucks that haul coal have high volume beds that look ridiculous. So how does any one on here know? Unless your the operator and seen the payload measurements.

@godackgudalach1 that's pretty much right on the money for a load, it's not overloaded at all.
