Hi EngineerTex, Thanks so much for your comments. Apparently, Sitema has quite tight clearance tolerances and when this is combined with outdoor use and dirt/frequent cleaning, they feel their products were not suitable. Also, the HRC for the passing rod itself in a Sitema locking system has to...
Thanks again, Ted, Tex & Brian. Somehow the commercial probing machines are able to apply at least 200kN to lock the soil probe in a tiny compact unit whilst not appearing to be using massive amounts of force as we have been discussing. I have attached a few Youtube examples. I also spoke to...
Thanks for your swift reply Ted really appreciated.
So does this mean: I require a holding force of 600kN, assuming a steel to carbide coef. of 0.5? (60 ton of force seems very high?)
assuming that the clamping area is approx. 134 cm2 so: 134 x 0.5 = 67coef.
Then: the (dry) hydraulic cylinder...
Hi everyone Merry Christmas to all. I am wondering if some knowledgeable person can kindly help me out with a formula or a calculation to calculate an approximate total holding strength of a steel probing rod being held by a hydraulic cylinder and rod clamps that will have a textured and curved...
Sorry Guys that is all I have to go on. I believe the tube is about 5mm and an estimated size of 90mm for the internal, maybe 100-130mm for the ext. tube? I saw this attachment at a fuel station on a tractor implement and thought taking some photo's would help me to find out what they are, I...
HI everyone, I am a newbie "L Plates attached" I am wondering if anyone here can identify what type of flanges have been used here and where they might be available to purchase?(see Photo/s). I am referring to the gold coloured flanges that attach an inner fixed tube to a rotatable outer tube...
