Mobile Crane (Technic 8094 Deluxe) . Set number 8094 captivated me when I first saw it. It was so advanced and impressive! I built the mobile crane and I was so impressed with its construction techniques and mechanical functions that I decided to build a Deluxe version with a cabin, electric light system and other details that were not included in the original set. I used parts that were available at the time (1990). . 8094's mobile crane has all the ingredients of a great set - nice looks, excellent functionality, unusual building techniques and innovative mechanical principles. It also has that impressive programmable control centre, which was the precursor to the mindstorms series. I built the 8094 mobile crane exactly as specified by the instructions, then I began adding a few extra items. This MOC is set 8094 with a few extras, but no major structural or mechanical changes (the set was pretty close to perfect anyway). Full mechanical functionality was retained, with a motorised rotating (slewing) turntable, motorised cyclic up/down motion of the boom and jib and retractable stabilisers. I added the following items: cabin, seated technic figure, control levers (purely cosmetic, although they do move!), traffic cones with storage areas (a small tribute to 855), whip antenna, ventilation grilles on the rear (part 4175) and a full electric light system including headlights, tail-lights, light-up instrument cluster and the flashing orange light on top. Routing of those wires through the built vehicle was quite a challenge, especially cajoling cables through the turntable! Running the lights' master cable out through the slot at the front of the vehicle required some de-construction, and did that more than once! I tried several methods of motorising a rear wheel with a micro-motor (they just fit under the chassis), including bands, chains and direct-drive gear trains. Alas, none of those methods worked - all bands slipped, the chain was either too loose or too tight and the direct drive just sounded very unhealthy! Your ears will become tuned to recognise good mechanical sounds and the bad noises if you build with technic for long enough! A view inside the cabin - the instrument cluster is built on a 2x4 electric plate mounted to the screen support. The light is pushed inside a 1x1 headlight brick, with a 1x1 transparent green tile on top, and transparent 1x1 plates of various colours mounted onto the antistud (hole) side of the headlight brick. Another headlight brick with a buttons pattern tile is attached to the stud side of the first headlight brick to even the whole thing's width. Two of the three movable levers are visible, with these two representing controls for the boom and jib. On the driver's left, there is a third control lever that moves from side to side to represent the turntable slew control. Also visible is one of the traffic cones in its storage area. I built a few extra plates into this area, giving a 2X2 area in which the cones can sit. A 45 degree 1x2 slope brick keeps them in place. It seems simple, but this works well - they are easily removed but they never fall out. The original 8094's two electric leads had their ends mounted to cross-pinned technic beams on both sides of the vehicle's front, being secured with only two studs instead of the full four. However, this worked-out perfectly when I added all of my electric gizmos! Light bricks went in front of the beams, allowing 2x2 plates to 'cap' the ends and ensure a very solid structure. I stacked all additional leads behind the original ones, using 2x2 plates to electrically isolate light leads from the motor leads. A 2x1 technic beam pinned on its side makes it impossible for the leads to come away, even if they are loosened from their mountings. The front is now particularly neat and everything works without any sparks! This shows how 8094 was built in two halves (have a browse through the instructions) - the top yellow half incorporating the boom and jib and the black bottom half with the turntable and stabilisers. This is almost like two sets coming together to form a super set. 8094 certainly had enough features to keep builders entertained! I will upload more photos and details soon, I just wanted to get this one out there! Thank You for looking :-)
