There are also "mechanical", propelled by propshaft and gears.
But only electric ones are capable to operate without running engine.
I am almost sure, that electric winch is not what you can expect on MAZ trucks, neither URAL and similar "weight categories".
For scouting vehicles of "A" class, why not, but bigger trucks doesn't make much sense with such thing I think...
there is an electric winch in the SpintireMod for mudrunner. i use it and it is Great. (i don't know how to put a link up in my reply, sorry) Rufus
ps. look for the thread 'spintire plus for mudrunner" in the 'Modding" category..it is a mile long, lot of useless info but it does have the link in the thread.
and i have pulled D class trucks back over
