RAINBOW SKILLED CRANE MACHINE

[MARKLPENA]

HELLO I AM A NEW OWNER TO A RAINBOW SKILLED CRANE MACHINE AND I AM TRYING TO FIND OUT HOW MANY WATTS MY MACHINE IS. I AM TRYING TO TAKE IT TO A EVENT AND THERE IS NO POWER OUTLETS AROUND AND I AM WANTING TO USE A INVERTOR OR GENERATOR TO OPERATE IT FOR AT LEAST 6 HRS.

It's generally an amps thing, but could easily be converted over to watts...There should be a build tag on the back where the card enters the machine...Or...Look at the manual...Or...Follow the line cord into the machine and it will run into a fuse just as it enters the cabinet, that fuse should be the amp rating (+25% generally for safety) Unless someone put the wrong fuse in there, but if the machine works that fuse would be a safe bet for calculations...the watts conversions are just a click away with online conversion charts.

I AM TRYING TO FIND OUT HOW MANY WATTS MY MACHINE IS.

A quick online search reveals that there's not much info on these machines.   

ChanceKJ posted a dropbox link to a scanned PDF of a manual here on KLOV.
- Not sure if the manual is for the same model as yours.   
- ChanceKJ also posts here so you can drop him a PM here if you don't have an account on KLOV.

On machines like this, there's usually a manufacturer's serial number plate that lists voltage and amps.

Plug that info into the formula for wattage.
    Watts = Volts * Amps

If you're using a generator, you should have no problem powering your crane machine -- the limiting factor is how much gas the generator burns per hour.

If you're using a power inverter, you'll need one large enough to handle the crane's wattage and a battery that can provide that wattage for at least 6 hours.

For example, if you crane machine draws 4A @ 120v, that would be 480W (4A * 120v) so you would want at least a 500W inverter.

To run that inverter for 6 hours on a 12v battery, the formula is
    (Run hours * wattage) / battery voltage = Amp Hours needed
    (6 * 500) / 12v = 250 Amp Hours

Multiply that value by 2 if you're using a deep cycle/marine battery or by 10 if you're using a normal car battery.
- Discharging a deep cycle/marine battery more than 50% or a car battery more than 10% can shorten battery life.
     250 Amp Hours * 2 = 500 Amp Hours for a deep cycle/marine battery
     250 Amp Hours * 10 = 2500 Amp Hours for a car battery

Then add another 20% so you've got some wiggle room. (multiply by 1.2)
    500 Amp Hours * 1.2 = 600 Amp Hours
