SUPER LEGO CRANE TRUCK
building instructions included !

Februari 2005. This page shows scans of photographs of a crane truck that I built in the sommer of 2000. The inspiration for this model came clearly from the LEGO technic super truck 8868.

1 motor for driving
4 steering wheels
the 4 rear-wheel-frame behind is connected with one rotating axis between the wheels to the truck
1 Motor and a 4 way transmission selection for : (1) steering, (2) moving down or up the stabilization feet, (3) rotating the crane , and (4) generating air pression for pneumatic control of the crane
3 valves for controling the arm of the crane

The four way transmission selection, the steering and driving is explained partly by the following 2 pictures.

A second motor, for steering, moving the feet, rotating the crane and pumping air, drives the four way transmission selection with the yellow elastic string. A handle attached to the axle, and sticking out of the front of the car, at the right side in the picture above, is fixed to select a transmisison.

The following images show the 4 states of the transmission, controlled by a fixing the handle in front of the car

pushing down or pulling up the stabilization feet

the handle is fixed to "12 o' clock"

I have about 70 photographs taken during the process of decomposition. This truck could be reconstructed by watching these photographs in reverse order. The building instructions are a series of 10 pages with about 6 photographs per page.
