They do bridges that way, and untill you have had the pleasure, or pucker up
and chew a hole in the seat experiance of a tractor's rear axles kicking
out to side pulling 80,000 lbs gross , or the trailer kick to one side or
the rear tractor axle kick out to one side when braking, dont yak at me on
this. The damn things flat suck for traction. Thank god they dont use
steel grating very often for bridge surfaces any more. and before
experiancing that joy, I used ramps of that construction to unlaod trailers
and trucks in the service at areas that didnt have loading docks. Even with
a 4k or 6k lb forklift you had to be damn careful becuase if you hit the
brakes to hard coming down, the tires would lock up and slide. Lift
operators learned real fast better too slow everytime than one time too
From a strictly personal perspective, the steel gratings that I have
had the "pleasure" of driving on differed greatly depending on age. The
new ones had traction galore, those that had been in service for some
time and driven on regularly were very slick. It has much to do with how
many tires have driven over them and smoothed off the edges of the
steel. It also varies greatly depending on the relative hardness of the
tire compound, a soft tire on a new grate will have very good traction,
to the point that it will try to shred a tire, older grates with hard
compound tires will slide at an alarming rate.
Same here. I'll bet cleanliness counts too. Some have a nice oil &
grease coating if traffic sits still on them.
I've ridden bicycles over lots of them and seen a wide variety of
traction. Think a slippery grate is scary in a truck? Try the
slippery, slightly downsloped examples on a 25 MPH bicycle with a car
20-30 feet behind.
On the bike, I can even see a huge difference were the tires usually
travel and where they don't.
