Quoted from EalaDubhSidhe:The 'right' answer, for those not so familiar with engineering, is more than just raw parts. What makes the crane 'complex' isn't the mechs per se but the control and engineering tolerances that factor in. This would have been more difficult for a company like Data East Pinball in 1993* than Stern today. R2D2 doesn't need to worry about that, the movement is vertical and the weight is balanced. If he wobbles a bit, it makes no difference. But LAH was the first time anything like the crane had really been attempted in a pinball environment, and it wasn't going to be perfect. It needs to be strong for the long horizontal length and ball hanging off the end not to act as a pivot. More important are the control switches that tell the mech how and when to start and stop - if those fail for any reason, the motor may decide not to switch off and keep trying to push the crane past the start or end point. That's where the burnout risk would lie.
(*One reason: in order to stay competitive with Williams, Data East had to beat them to the punch with a number of 'industry firsts' with fewer resources to spare. First 'solid state' flippers, first DMD, first sound board to replace the Yamaha synth. According to the IPDB, the first DMD was put on Checkpoint instead of Simpsons because if the new display had been rushed and failed to be reliable, management were concerned it would bankrupt the company.)
1) I engineered fuel injection and turbocharger systems, I might know a little bit about engineering. I also build wiring harnesses and various pinball mechs from scratch, for fun.
2) The post above is borderline embarrassing, just tell us you dislike Data East directly and I'd have more respect.
The T-Rex mech in Jurassic Park which was released before LAH is far more complex than the crane. All the crane does is bang stop at one limit switch and reverse course to the other limit switch (which pretty much describes the T-Rex L/R animation when ball capture is not in play) at which point it simply releases the ball. The tolerances are of minor account because all the crane has to do is bang back and forth till it hits a switch. Crane too tall or too short? Loosen set screw on shaft to adjust. It's pinball, complication is bad for operators.
There is no voodoo magic engineering here. 2 switches, 1 coil and a synchronous motor, it's practically caveman tech. The same door open/door closed motor and switch routine was used on Phantom of the Opera in 1990.
I'll simply assume you have never laid hands on either physical pin or dislike for DE has clouded your judgement or both.
Your argument is easily refuted by anyone who has serviced & repaired a LAH, SW or JP pin in any depth.
Done.
