I spec forks by their "class" i.e. class II for trucks up to 6000 lbs. or 3000kg, then class III, IV, etc. and fork length and width and thickness, all in fractional measurements. if i need a special tip profile or a fully tapered and polished (or FTP) or lumber fork, i specify that, or a brass-clad explosion proof fork, or with drilled hole in the tip (it's better to specify this on a new fork rather than drill it later to an unsafe size or position). and never torch-cut a hole in a fork! this anneals the fork and instantly fails it in an inspection as the tip can now bend or break off.
As they say "Peace, Brother"
Almost all forks produced today are metric sized not American.
For example what used to be 1.5" x 4" is now 40mm x 100mm.

Sorry, but allthough the subject is the same, the content is not exactly the same in the two massages. In the previous massage (in the Technical section) I asked about the the central link purpose, and I got some answers, In the last massage (in the Lifting machines section) I quote the previous massage and added a new question about metric forks. I thought that the suitable arena to ask these questions is in the Lifting machines section because and according to the detailed title of Lifting machines section which includes attachments, parts,and components disscussions...
But, really this is not the importatnt thing to argue about, maybe you are right and maybe you are wrong, lets be practical and try to get answers to the questions (olds and/or news).
Thank you
Why do you post the same question here when you listed earlier in the Technical section and have received replies?
