Hi all, looking to better understand wiring in various order pickers (e.g. Crown 3400, 3511, etc.). From the manuals, it seems like all power management happens in the main motor compartment on the ground. The platform (which goes up), only has the wiring for controls and display, but no power line (e.g. 12v/24V, etc.). How does one typically add things like vehicle-mounted computers to these vehicles? Where does the power come from or do you need to add separate wiring that goes all the way up with the platform?
Any insights/tips would be appreciated.
Thanks,

well lets make sure you understand the difference between power circuits and control circuits.
Generally the power circuits referenced in manuals refer to the motor control side of the machine, the large cabling associated with the motor and battery. The control circuits are the smaller wiring in the wire harness that connect the components that control the machine.
Now you wonder how they get the wiring up to the platform? Usually there is a multi-conductor cable that runs through the mast connecting the base with the platform. This would be how they get power to the platform.
Like forkingabout says though, if you do not have the voltage option you need at the platform power then you would need to use a dc/dc converter to supply the voltage you need for your components you're trying to power up which could be connected to the power circuit connection at the platform. (unless the components you're installing are the same voltage as the power supplied to the platform).
Just keep in mind the amp rating of that circuit when your adding accessories to that circuit, you do not want to over load that circuit with your added accessories.
I known on the BT man up machines there is a 10 amp fused truck supply voltage accessory plug ( X42 ) in the operators cab for adding on a RDT unit or a DC / DC convertor, the BT stuff has been like this for the last 25+ years.
The plug is normally behind the dash / blanking plate or inspection cover.
