This is a modified version of 42079 Heavy Duty Forklift, built as an alternate of 42078 Mack Anthem.
I had to modify quite a lot of things: * Because I couldn't use a worm gear the mechanism to lift the fork includes more gears. * Then with no worm gear the fork would lower itself by weight, so I included a seemingly useless gear inside the body which brings friction to the transmission. * The engine is a four cylinder Mack style engine. And it's mounted lower than in the original forklift. * Because of missing flexible axles I came up with a solution for a door. * The rear mudguards are shorter because there weren't enough 1x4 half beams. So I made the whole wheelbase 1 stud shorter, which also helped to make the smaller wheels look less lost. * There is a transmission with two 8 tooth gears inside the body of the original which could not be replicated with the parts, so I redesigned the internal structure completely. * The fork is mounted differently because I was missing angled beams in the right length. So I used a construction with angled connectors instead. * And some more changes.
A string is not part of 42078's inventory and has to be added.
