Is this block for at the bottom as another brake somehow?  I don't see what you're doing with it yet.


I'm copying what everyone else is doing. They put a block on the zip line
with a Bungee cord attached to a fixed object.

I see perfectly now.  Thanks for that.

Here is some close pictures of the trolley. I'm real happy with it but don't
use V-belt idler pulleys. Mine are shot already. You can see where the cable
cut all the way to the outside of the pulley. That little dark line in the second
picture is the cut. New pulleys are on the way (3rd picture).

How may trips did it handle before it got to this amount of damage?  No danger, really, as the cable would have busted out of the pulley and just hit the pulley's bolt, right?  Maybe have a little time pulling someone up/down to get off the trolley?  Are the pulleys you're getting similar to what others are using on their zip lines?

There is two pulleys and 4 bolts that the cable would have to eat through to
Get out of the trolley. Grade 8 bolts. We got around 60 rides before this problem. I seen the cable eating into the pulley so I was keeping a close
Eye on it. Even if it destroyed one pulley shifting your weight would have
Gotten you down the cable on the other pulley.  If that dint work there is a 1/2"
Rope under the seat so if any thing happens you can go down the rope to
The ground. The new pullies are the best that I could find. They are solid steel.

Heh.  A getaway rope under the seat, I love it!  :laugh:
I imagine these new steel pulleys will last a very long time.  If they get to wearing out I can see you welding some friction/wear plate rod into the groove and machining flat again.

I would have loved to have found solid yellow brass wheels.
I don't want to cause any wear on the cable.
I will be keeping a close eye on the cable.

Getaway rope... It's all part of the same rope that holds the seat to the trolley...

Cool!  Love the rope scheme.

I was thinking after I wrote the last one that anything harder than the cable is going to wear it out which isn't good.  But it is a rolling load so likely it'll flatten it somewhat I would think.  Hopefully the steel in your new pulleys and the steel in the cable are similar so everything will be dandy for a long time.

I got one problem...
When I put the bungee on and the trolley gets push back after it stops you
I need a way to get down off the cable. With out the bungee it's not a
problem because you can walk up the ramp to dismount. I don't want a ramp
where someone can run into it. I was thinking maybe a dirt ramp mound
back where the trolley will come to a stop.

Anything I put there someone might hit it.
You get up to my guess 60mph .
I'm thinking the best thing is a mound of dirt that very slowly ramps up.

Saying it that way I guess I'd agree with ya.

KB,
With all the stuff you have on hand, I'm sure you could rig this up (hydraulic or pneumatic?).  At little fairs, they run mini-ziplines.  They have a tower you climb up (counter balanced with a BIG water tank) and a trailer unit that is staked to the ground.  They run the cables (two parallel runs) through some pulleys with hydraulic rams.  It is set up like a reverse block and tackle so a little movement of the ram changes the length of the cable a lot.  With pressure gauges, they set the cable tension.  They up the tension if they see a BIG rider :D  When the rider is done (bounces off a big, long spring on the cable), they release the tension and lower you to the ground.  I'm thinking electric over hydraulic setup or maybe air pressure?

Almost got my second trolley finished. It's unbelievable how much
time and work goes into a little thing like this. I think the hardest
part is making the rubber block. Have you ever tried cutting solid
3" rubber before? I'm ready for spring.

Metal fabrication has always amazed me at how long it takes and what little you have to show for your time sometimes.  Chainsaws cut rubber very quick and easy if you've never tried it.  Gotta make sure the rubber is held down pretty good though.  The only other way I've found is to melt/burn through it.  Outside of course!  :D
I wonder if a tire siper would work as a cutter if you take multiple passes with it?

I bought a used forklift real cheap because the seller said the axles
was bent... The axles was not bent but the tires was egg shaped.
I jacked up the forklift and fired it up. I put it in gear and let the
wheels spin. Then I took the chain saw to it. They cleaned up real
good. To cut my zip-line blocks I used a 6" cut-off wheel in a side
grinder. Sure made some smoke and now my coat stinks.

Yeah, I've cut rubber that way too when I had to.  Not by choice, though.  I remember the smoke and stench.  That crap will almost take your breath away.  Not to mention the little pieces of molten rubber flinging all over the place!

Yea I learned a new word today. When you cut the rubber with a
cut off wheel the rubber melts and stays melted. So I googled why.
It's called reversion. It's when the rubber breaks down. I do know
once you get that stuff on your hands it's just about impossible to
get it back off. Many years ago I got two forklift tires that was never
put into a circle. They was eight feet long four inch thick strips of
solid rubber. They sure have come in handy over the years for
different projects.
