I love chain falls! I hate falling chains! The brake mechanisim on my crane hoist runs metal to metal and is greased. No chance of breaking one of those fiber washers and spitting it out while holding the load that way. My Yale has the friction surfaces recessed so the fiber washer is captured so again in case of failure it can't come out. I guess that is one of the features that costs the extra price.
Thanks you're the only video I found so far that explained at all how to set that clutch. Everything else seems pretty straightforward. So lightly tighten the chain wheel all the way down, then run the nut down? Then back off the nut one notch... do I have that all correct? Got a cheap POS chain fall I'm going to try to make work halfway smoothly before I chuck it.
Lube is BAD in all the wrong places!!! A young man working at my father-in-laws garage, back in the '60s, tried to shoot grease into the brake bleeder valves during a lube job!! - Great little video. (Edited for punctuation, which is probably still incorrect!! LOL)
I have 2 hand operated chain-come alongs that we're tightened until they ran out of chain & hook bottomed out. anyone got video of repairing them? thanks
Wow you repaired a broken piece of equipment? I thought common practice was beat the hell out of it till it breaks and then trash it!! Great video thanks i was wondering what i should do to resurface the brakes on this come along i got
This is a very common design, a little oil in the right place is a wonderful thing, but a slipping clutch is irritating and requires you to "babysit" the operating chain to keep the load suspended.
I recently bought a lever hoist from a scrap yard locally that has roller chain (like motorcycle chain) instead of standard link chain. It was heavily used but still works and they look to be very expensive new. I got it for $20! Here is the ones offered by Yale although mine isn't a Yale. www.yale.de/en/products/product-range/hoisting-equipment/ratchet-lever-hoists/yale-ratchet-lever-hoist-with-roller-chain-c-85/ Mine is the 1'' pitch chain version that's rated 1.5 ton. Quite a beefy roller chain. I took it apart and the brake mechanism really had me stumbled. Once I read about it it all made sense. It's known as the Weston hoist brake after Thomas Weston. Here's a good explanation. www.harringtonhoists.com/tech_support/edocs/EDOC%200467%20rev00.pdf The part about ''a series of controlled load falls, which is perceived as one smooth lowering motion'' was a light bulb moment.
Some one mistakenly believes every metal surface should be lubricated locks should as you put it remain dry friction is the friend of mankind keeps us on track and off our butts
