Okay, so I had a customer call today on an Ingersoll-Rand SP42 that I have for sale. He asked me what the applied force was for the drum and I told him 21,200 lb./imp. Next question... what does IMP stand for. I felt a little silly that I couln't give him an answer and told him that I wouldn't sleep until I found out. Anyone have and ideas? Is it 3 words or does it just simply stand for Imperial? Keep Rockin' This is me right about now .... v:Banghead
Isn't it Impacts per min
Imp ? Hello Cat966C, Caterpillar calls Frequency, VPM or vibrations per minute. As in 1800 vpm. The Centrifugal Force or "applied force" has a Max and min ratings, in lbs as in 74,600 lbs or 37,300 lbs. The use of High Amplitude or Low Amplitude determines the amount of Centrifugal Force. I see nothing that relates to your lbs/imp rating.
Would it be pounds per impact???? :beatsme
I thought Impacts Per Minute as well. But then that would be IPM. It's most likely just IMPACT. Thanks guys!
Down Under, it is common practice, when something is stated in imperial units(British system....feet, inches, pounds etc) for the suffix "imp" to be added. I would read your spec then to be 21,200 imperial pounds "lbs"...but thats just me take on it.
