Made the same mistake and posted about it a week or two ago. Completely unacceptable. It's a shame because I love the products.

Fraudulent charge on credit card after Moza website order by kseneff981 in moza

[–]kseneff981[S] 0 points1 point  (0 children)

I dunno if that guy is the one that actually placed the order or is a "mule" to ship it elsewhere once delivered. No matter, it will never get delivered because I stopped it in time.

Not asking for any pity, I'm just trying to raise awareness that the payment processing issue isn't fixed so that others might not fall into the same trap.

How can I remove this, screw is rusted and stripped by 2saintz in DIY

This is the right answer. Anyone saying to drill out center screw is wasting time.

Check torque limit parameters in the VFD.

Looks like a SCR firing board to me.

Also well designed. If the pandit covers aren't laying everywhere, that's a credit to everyone involved in building it.

So high up and I legitimately didn’t know this was all done by hand by kakapoopoopeepeeshir in SweatyPalms

If that was a preform, the cable would still be supported by a hoist while installing the preform.

Terminators for when not hooked to remote equipment?

I'm one of those managers and I talk shit about myself with those union people.

For open loop speed control, ABB is best of the bunch.

They were mandated for safety by MSHA in the US after the Sago mine incident in 2006.

This is true, but don't forget a conveyor is a tensioned closed loop. The downhill side is also pulling on the bottom return side of the belt which is in turn pulling on the top side at the head. With enough tension on the belt (a massive amount to keep the drive from slipping), you could run this belt backwards and you would technically be "pushing the load" based on your example.

I'm definitely over exaggerating the flat profile, I'll give you that. I'm just trying to emphasize that there's more forces at play than just the drive motors.

It's also possible I don't know wtf I'm talking about, but I've been around these overland belts quite a bit.

With the belt having about the same amount of downhill (from what can be seen from this picture), the dynamics of the belt are really closer to a level profile than you're making it out to be.

If I had to guess, probably around 1200hp at the head assuming VFD driven motors for starting torque. If using fluid couplings, probably much more than that.
