LEGO 42078 Technic Mack Anthem

Product Information

This LEGO Technic advanced building set is designed to provide an immersive and rewarding building experience. There's a mechanism operated by the gear on the side to raise and lower the balancing wheel, for use when it's not attached to the tractor unit. Fill out an Inventory Change Request ( ?) [ Show Inv Item IDs ] if you found an error in this inventory. Now we turn our attention to the trailer. The chassis is a straightforward Technic build that comes together in no time. It's a rigid structure, thanks to the use of 3x11 panels.

There is just one new part in the set: the gold bulldog hood ornament, which has a 1l Technic axle at the bottom to allow attachment. Generally, once you have the hang of it, it works well. The knobs require quite a lot of force to turn, as a result of the weight of the container, so once the novelty has worn off you probably won't be operating it frequently. Features authentically designed bodywork, front-axle steering, rear wheel drive, 6 cylinder straight engine with moving pistons and spinning radiator fan, detailed driver’s cab with opening doors, adjustable seats, steering wheel, dashboard, sun visors and a bunk bed, and adjustable wing mirrors.Features authentically designed bodywork, front-axle steering, rear wheel drive, 6 cylinder straight engine with moving pistons and spinning radiator fan, detailed driver's cab with opening doors, adjustable seats, steering wheel, dashboard, sun visors and a bunk bed, and adjustable wing mirrors. The container lifting mechanisms are built as separate subassemblies then attached to the trailer once complete. They are complex and take a while to construct. One is the mirror image of the other so you might not want to build them both in the same session; I certainly didn't! As a result the cylinder movement is not accurate because, as you'd expect given the parts used, the cam offset is 90 degrees, so during the cycle two cylinders 'fire', followed by another two, followed by one and then the last one. But it doesn't really matter...

There's some neat mechanical coupling involved to get it working in the confined space available, which you might be able to see in the next two photos showing wheels turned left and then right.The trailer is more 'traditional studless Technic' than the Anthem but that's not a bad thing at all. The unloading mechanism is suitably complex and works well once you have the hang of it. This LEGO® Technic advanced building set is designed to provide an immersive and rewarding building experience. Construction begins at the rear of the chassis, which is fairly straightforward. The axles are connected via differentials, as you'd expect. Above the wheels the plate for attaching the trailer can be seen.
