Model Forum / General / Models / September 2007Gates hydraulic hose crimper
A bit OT but does anyone have experience with / recognise this Gates hydraulic hose crimper that followed me home recently: http://tinyurl.com/245yky It's operation is very simple in that it closes like a collet chuck, squashing the ferule round the pipe. The squash is by a hydraulic cylinder and the closer has interchangeable fingers for different sizes, and a calibrated end stop presumably lets each set of fingers cover a range of sizes. I believe it does hoses with bore diameters of 1/4" up to 1.25". However I reckon there is probably a table needed to look up the stop setting for each fitting size. Nothing exactly like it on the Gates site and so far they don't answer emails ! BTW it weigh around 40KGs !!!

BTW it >weigh around 40KGs !!! Looks much the same as this one:- http://www.goindustry.com/en/equipmentdetails.asp?sOfferID=1177221 That one looks to have a book with it. A curious feature of Goindustry auctions, I've met it before, is that the final price was exactly the same as my maximum autobid, and was submitted *after* my autobid. I'm sure there's a rational explanation as to why bid wasn't the one which won, probably his autobid was higher than mine but???

I actually got through to a helpful Gates chappy today who reckons mine is a Gates USA version. Apparently the two companies make similar but incompatible fittings and crimpers!! But he was a gloom and doom merchant wringing his hands and saying don't make up hoses as H&SE will chase up the bloke crimping the hoses in the event . . . . Probably right at a theoretical level. Another gem he dropped is that Gates have ceased making their longest running hose fitting range in favour of a new (and more expensive) range that is no longer compatible with the older crimpers. Personally I would have thought if you adjusted the old crimper to squash down to the recommended final diameter of the new fitting it would be crimped and the fitting wouldn't know (or care) which crimper squashed it there.

Can be a can of worms unless you're prepared to experiment. Tend to reduce inner tube diameter, particularly on smaller sizes. People soon learnt to have a relevant rod to insert in the being crimped fitting to check for diameter reduction. That worked on straight fittings, for swept bends and angled fitting required using the previous research. :-) In the bigger sizes the crimper tended to behave itself as it was encountering a lot more resistance. I may have some info later in the day if can persuade someone to go dig in a filing cabinet. However, owing to all the generic fittings about any setting chart tends to only a guide rather than a specific setting.

Good tip re a rod down the pipe, but it conjures up an image of all these pipe fittings blocked with stuck rods <G> AWEM >>>A bit OT but does anyone have experience with / recognise this > [quoted text clipped - 55 lines] > > AWEM Ahem, perhaps I should have wrote that in laundromatese? :-) One checks after one squeeze, perhaps?

Tom >A bit OT but does anyone have experience with / recognise this Gates > hydraulic hose crimper that followed me home recently: [quoted text clipped - 12 lines] > > AWEM I think these crimpers are designed to bottom out so as to establish the correct degree of crimping. The dies are intended only for the specific fittings recommended by the manufacturer. They are pretty fussy since a failed crimp in a system with high pressure hot oil can be very serious. They are most likely to blow off when you have the forklift up high with a heavy load! Don Young USA >>A bit OT but does anyone have experience with / recognise this Gates >>hydraulic hose crimper that followed me home recently: [quoted text clipped - 21 lines] > > Don Young USA Not that simple, Don because each set of dies has to deal with two different scenarios:- 1 and two wire hose, so settings do come into it. The problem normally lies in over-crimping rather than under-crimping. Tom |
