New episode! Hope you guys enjoy: Special thanks to @testfly !

Oops. I woulda bought em. Sounds like something shorted near the bridge.

With the machine I had pictured, it either used a potentiometer or rheostat for controlling the strength (depending on the PCB revision, I owned a few of them), which could be adjusted to anywhere between "decapitation hazard" and "impossible to win". I also had to remove a small ramp from the...

My recommendation (as a registered claw machine professional) is to get one of these and swap the claw with a plush claw: Smart Industries 90's Candy Crane. They're about 24" x 24" and can easily be loaded into a pickup by one person. I've found multiple of them for around $150 each if you're...

I will see if I can modify your drawing later, but for now, try to make it work like the one I have attached. At the very least, I think you'll need to add a relay.

Thank you! If you have any other questions I missed, feel free to reach out, since my machine is almost exactly the same as yours, mechanically. Worst case scenario, you could easily work around the lockout coil by tying into the wiring somewhere- you can use the circuit diagram I made to try...

I ended up finding what looks the same model as your machine online. The guts are all on the second level and the bottom looks to just be a coin counter. Most importantly, the mechanism looks exactly like the one in this video that I did, so this should help you at least get the machine working:

ACTUALLY, that looks like it could potentially go to one of these time delay relays. I had an old crane that used one of these style relays once: https://static.grainger.com/rp/s/is/image/Grainger/20XG05_2

I have two videos on digger cranes, neither may help but you may be able to figure something out with them: Worst case scenario, it probably just connected to a simple circuit with a relay or two, and you could probably figure out a way to make it work yourself. Would love to see pics of the...

After days and days and days of editing footage that was filmed around year ago, I finally finished this episode of Coin-Op Corner that @CharlieG helped out with. It's about a vintage claw machine that's almost 100 years old, and the journey through repairing it. Be sure to check it out and...

String might be wound up backwards. It might try to drop but instead it's pulling back up. It also might be that the switch that tells the claw it's reached the top is either engaged or not engaged when it should be the opposite. Try playing the machine while holding down the different limit...

I honestly find some of them to be more fun or interesting than video games. I love how most of them are predominantly mechanical in nature too.

Completely possible. I've had that issue with ICE cranes before.

Check everything first, make sure it's actually the relay and not a shorted diode or transistor.

In fact, I bet you that is exactly the case. The relay or transistor that controls the down movement is probably shorted and constantly telling the claw to drop. Then, when the upper limit switch sees this, it immediately tells the claw to go back up. Thus, bouncing.

It looks like the motor itself, or maybe the relay / transistor that drives it, may be to blame. The way it's lowering when it gets over the prize chute indicates that something else may be wrong. Like it's constantly trying to lower when it's not supposed to. Which explains the bouncing.

Exactly! Those machines are super fun to work on because they're so easy to diagnose like that. Hopefully that gets you going!

It constantly trying to raise up, after it's raised all the way, indicates that something is probably wrong with the upper limit switch in the trolley. Even if it registers on the test, it may be flakey. I would try that before I did anything else. Also, I don't have any of these machines, but...

That's absolutely awesome. I've always been particularly fascinated by them as mechanical devices, especially the older ones like that. That's why I own three of them now...

Funny that everyone's finding this video again, this post is over 2 years old.
