The bad news is;45 below plus; Fahrenheit and Celsius Temperature Scales both meet at forty below:It all boils down to the machine the company and the Operator Skill Set;The records never been set and if it has, no one has admitted to it.

The coldest for me has been 25 on a bridge project. I was amazed the engineers allowed it. Also the wind had it down to 12 wind chill factor. Thank God most people dont pump at that cold.

14 degrees here in Atlanta GA. Showed up on the job @ 7am only to get my first load around 2pm they had to thaw the plant. http://www.pumpoperators.com/brian/ I love to pump concrete. It is in my blood. I will do whatever it takes to do the job right and safely! Almost 20yrs under my belt and still learning.
