Floating Gears on an incline? Missed a gear on an incline.

Yes they do. Just like the snub braking vs steady pressure threads.

 

That's my problem then. My only experience is 1 year behind a S60 DDEC IV and 10 speed where the engine brake engages at the very top of the throttle. Extremely difficult to hit the cut-in point on the engine brake at the right time. For starting on steep inclines while loaded heavy, I've found it best to keep the engine fan on, run the rpms up to around 1700 before the shift, then do a quick double clutch and make the shift assertively. I did my best to plan my approaches to inclines such that I would not be caught by traffic or traffic lights and consequently have to come to a stop before reaching the top. Compound that with a bad high/low range synchronizer that made it nearly impossible to shift from high range to low range without stopping the truck, and you can imagine the planning that I had to do when it came to climbing steep grades in traffic on two lane roads. I'm moving to a different truck this week, so things will likely seem a lot easier. edit: why can't I add paragraph breaks now? Something wrong with the site?

 

On different trucks you just have to do what you can. My KW had the super 10 and a 12.7. I almost had to use low jakes to get it in gear. A Cat is easy to take off up hill and use very low rpm's and quick shifts to get started. After a couple times it will become second nature.

 

Moloko its good to have confidence but its also good to always be cautious. I think we have all missed a gear or two the key is to combine both shifting techniques day in day out day in day out day in day out........next thing you know it will become just reaction when you face a situation or when you switch trucks. Regardless combo that shifting and stay calm. P.s. good job getting the job. PeacE!

 

I switch between floating and double clutching when driving depending on the situation, as for the road test I only double clutch since that is what a lot of companies want to see, not ####y and impressive floating....I know my company is totally against floating.

I never use a jake going uphill just down, next time you lose your gear look at your speed and go for the next gear when you lose rpm and speed and then start again. I know when you miss a gear like that it gets frustrating and then it takes a little more time to react and fix the situation, I havent done it in awhile but it has happened especially a few times when I first started driving.

 

With floating you have to hit is just right uphill. With the clutch you can be off some and still grind it in, though it's better to not have to do that. Even if you don't grind, you do have some leeway as soon as the gear teeth mesh up using the clutch.

 

Your ground speed and RPM change rapidly on an Incline. Apply the right technique/skill to accomplish the task. DC is the correct way to shift when pulling a grade w/ a load from a stop. Say in 20 yrs you are still trucking and you stop on a grade 8-12% and try and float the gears,you still won't get'r done. Floating gears does not work off road or on steep grades. It's for driving on flat pavement.

 

I agree, I hardly ever float when climbing, sometimes doing downhill but you still have to be faster because of the rpm changes rapidly compared to flat surface.
