Plowing airport runways I've hit 50mph before, 55mph is lift off speed for a pickup and Boss, and since I don't have my pilots license current, thats as fast as I can go
Alot depends on location,bigger parking lots can allow for speeds of 25mph,apt. lots 5mph can be the max it all really dependson what the conditions are what the driver is comfortable with.This is an issue that is a good example of why competent drivers are so important,because you are not always there and you are asking them to use your equipment safley and properly and that means the proper speed for the location.Actually setting a speed means on some places drivers will be dogging it and on others they will running at the set max. I always tell my drivers to be gentle if the truck breaks down and isn't repairable they'll be going home and theres no pay when there at home.
Just from a common sense standpoint, I have to agree with both of you. I can't imagine going 15 mph through some of the small, adjoining 6 flat lots, but open lots that are empty, 15-20 doesn't seem like it would be out of hand. Common sense would tell you to slow way down as you approach the snow bank, curb, or other obstacles.
Obviously, the first few times out would be slower so as to know what obstacles are hidden beneath the snow, and slow down for them. Manholes aren't marked with red flags, so I realize there are many obstacles that could be encountered and slamming into something, even at 10 miles per hour should be avoided.
I just thought 10 mph was slow when I was imagining being in a wide open space. .
I guess good judgement is the key here, rather than hard and fast rules.
Let me clarify my statement a little more, the large lots and long drives where we are achiving max speed are places we have done and know that there are no obstical issues.Plowing at more than 6mph to 10 mph in unknown areas shows a driver is not taking proper care,unless its me and I do what I want because I have to fix it if I break it.
Is it possible that plowing too SLOW canm be bad for the truck? We've got a guy here who plows like an old woman,, maybe walking speed. He's running a GM 2500 with a dump insert and a vee box inside that. He also has a LOT of tranny trouble. I kinda wonder if he's not getting enough revs to lock the transmission up good and solid.
Sorry, I re-read my post and it DID kinda sound like the turtlke worked for me. No way! He's just another plow contractor in the area. Anybody working for me damn well better be MOVING when he's on the clock.
