click to zoom




some tech info:

 here you can see the battery. for reloading the battery the axle above must be pushed. very simple

 in the cab is a IR receiver. this one is for driving. the 2 wires on the right side are from the 2 XL motors

doors can be opened

3 IR recievers for the wrecker unit. covered with a 3x11 technic plate

side wall off. now you can see very good witch functions work on witch way (click = zoom)

i decided to not connect the 2 crane winches to each other. now you can tilt a truck on 1 side up.

all the gears are needed to go from the middle of the truck to the big LA's

LA's 100% extended

ya, you can see my lonely Toyota FJ without a chassis...

a large LA is for lowering the fork 

after some experimenting i succeed to put a worm wheel on the extendable boom

if someone knows something i can build next on this truck. contact me!

wrecker unit haves to connect the wire to the distribution place (see photo)

the rear wheels are not connected to the front wheels but haves there own XL motor

steering axle haves to transport the front axle movement to the second axle with a little slowdown

the 2 L motors are in the middle of the wrecker unit 

i had some inspiration ideas from chang fei's moc (heavy duty tow truck)
but i only used the crane boom worm wheel idea

his wheel lifter isn't powerfull enough to tilt up a other big truck on the front
my wheel lifter can do it easy
thanks to a LA
