I've been measuring and testing approach, departure and breakover angles, and this is what I've discovered: 1. A truck can't begin to climb, without scraping the front low spot, any slope steeper than it's approach angle. Doesn't matter if the slope is short or if it's long.
2. A truck can't exit, without scraping the rear low spot, any slope steeper than it's departure angle. Doesn't matter if the slope is short or if it's long.
3. When approach angle exceeds departure angle, a truck can't climb a slope, without scraping it's rear low spot, that is both longer than it's wheel base and steeper than its departure angle.
4. When approach angle exceeds departure angle, a truck can climb a slope greater than the departure angle, without scraping anywhere, provided that the slope angle is less than the trucks approach angle and less than it's break over angle and the length of the slope is less than the wheelbase of the truck.
5. A truck can't fully exit nor descend a slope, without scraping the undercarriage, that is steeper than it's breakover angle.
6. Approach and departure angles change when driving down a gully and up the other side. Again assume approach angle exceeds departure. When the truck starts up the opposite side of the gully prior to the rear of the truck leaving the descent slope the departure angle will be reduced when the front tires reach a height greater than the rear tires. In other words, the decent hill must be less than the departure angle. Also the approach angle is reduced when the rear wheels are higher on the slope then the front wheels. As such the slope of the exit side of the gully must be less than the approach angle to avoid hitting the front of the truck.

very well explained and live demonstration of most important offroading angles.. usually people just talk with pictures which makes zero sense !!

[rakeshm]

Very nicely explained sir thank you so much

[jaiparashuram]

Best explanation - you have explained it very well. Thank you

I like your accent. It is partly Spanish, British, or German together, of course you do not expect that, Saludos from Costa Rica. By the way may I use break over instead of ramp angle? Gracias

High quality video for way back in 2013.

I watched this to the end for the whistling

It's very uncomfortable to see this guy putting his head and hands under a 4x4
