MAJOR changes to SNO Power Plows

What happens here

The video delves into the innovative use of nitrogen in the plow's cylinders. Rick explains that nitrogen, being a larger molecule, provides a more consistent pressure curve compared to traditional springs. This technology is borrowed from commercial aircraft landing gear and military tank suspensions, indicating its proven reliability and performance. The nitrogen system offers better pressure management, reducing the draw on the truck's battery, and results in a smoother trip action.

Goal: Learn about the benefits and applications of the nitrogen suspension in the plow.

cylinder okay so let's just talk about nitrogen yeah why nitrogen why nitrogen I don't even know why you would use nitrogen well it's like a built-in spring but like for the trip when you have a spring I'm going to use fictitious numbers but you got uh 500 lb of hold with a spring as it stretches it goes 5 6 8 12 15 or 2,000 lbs of pole cuz it's being really hard nitrogen might go 5 6 7 8 because it doesn't it doesn't build all that pressure just smashes a little in it and then nitrogen is a larger molecule and that's what all the commercial airplanes use they use it every day for years they don't go down to the runway and check the nitrogen make sure we're going to land it just works proof okay so it it's in the landing gear of the suspension yes the suspension of commercial aircrafts it's in the suspension of Tanks the tanks yes that the military uses so that's when people started to ask me because you know we start to try to figure out why you do what you do this is the difference and I have seen now accumulators and nitrogen used in the uh the float function and heavy equipment as well that's correct Y and and I'm going to plug my son he worked in the military and he was uh the mechanic the Master Mechanic for the plane for the refueling and that's how we learned it because he has to charge that as to how much weight he's carrying and he knows that he doesn't have to change it unless the weight's there and he taught me the nud draulic system okay so this is your trip cylinder now that's the trip cylinder so the trip cylinder is going to the top of the blade back down to the frame versus at the bottom of the blade going back down to the frame which kind of makes sense to me yeah it's better leverages in all our whole hydraulic system I shouldn't I won't say the numbers I'll just say it's a lot less pressure which is a lot less draw on your battery all of our cylinders are are uh larger with bigger diameter which lowers the pressure so there we've got a the that's your accumulator your nitrogen accumulator the top one right there there's your main cylinder now you've got just this freaking big beef is big tank of a cylinder down here with the accumulator wrapped around the cylinder because that's a more efficient way of operating yes it's it's easier to put that around a cylinder than to take another cylinder and I drew from my back
