R Cubed Posted October 6, 2009 Share Posted October 6, 2009 Well since fitting my small Hiab type crane I have encountered it jamming up when loaded and slewing on several occasions, on braking the crane down I have discovered a thrust bearing missing off the bottom of the main base, also though, there is a thread for a nut which is also missing !!!!!!!!! What I am after is a nut and tab washer ( I think ) to stop the main upright of the crane riding up and over the top taper bearing and jamming. The nut is as near as to 70.00mm X 2mm does anyone out there have such a beasty or would it be something a good bolt supplier might have, any suggestions warmly welcomed ?

Chrisg Posted October 6, 2009 Share Posted October 6, 2009 The bearing will be the easy bit.you may have to get the nut made Quote Link to comment Share on other sites More sharing options...
N.O.S. Posted October 6, 2009 Share Posted October 6, 2009 I'm certain it will be a crane maker's special - big diameter but small pitch thread - and you should really be looking to get one plus a bearing from the manufacturer. Are they still in business? I can't remember what crane it was now and your photos have been lost...... Quote Link to comment Share on other sites More sharing options...
Richard Farrant Posted October 6, 2009 Share Posted October 6, 2009 If it is made by HIAB (often a generic name for any loader crane), then there is an appointed dealer at Worthing. If you want to contact Hiab, they have a website, www.hiab.co.uk Better to get the correct nut than having one made, which also may work out more expensive Quote Link to comment Share on other sites More sharing options...
R Cubed Posted October 6, 2009 Author Share Posted October 6, 2009 The bearing is a standard size and no problem to get, that is under way. The Hiab type crane is actually a Viper 20, as far as I can tell, no longer in production, however there is a company doing the Lucas swing lift cranes and has a model V20 which to all intents and purposes looks identical, and have contacted them ! Would there be anything special about the nut ? apart from size and pitch which is metric ( 70mm with 2mm thread pitch ) could I get one mage by say a gear company ?

Any good machine shop should be able to make one up for you at a reasonable cost (for a given value of reasonable!!) If you have a set of thread gauges it would be worth verify it is metric and the correct pitch - assuming you haven't done so already and this counts as instruction in the art of extracting nutriment from eggs!

R Cubed Posted October 10, 2009 Author Share Posted October 10, 2009 Mmmmmmmmmm nice new bearing and locknut..... Quote Link to comment Share on other sites More sharing options...
R Cubed Posted October 11, 2009 Author Share Posted October 11, 2009 Well all went well had to borrow some thread file, hmmm now they are a useful thing anyway after cleaning up the thread on the bottom of the crane, greased up the bronze bush ( you know its best to to have a greasy bush ) then on went the greased thrust bearing and then the new shiny nut, also had to make up a lock tab to stop the nut undoing and all is well.
