Catfish trailer

In this challenge, I've designed an aluminum frame weighing approximately 50 kilograms. The trailer features a lowering mechanism using two threaded spindles, which can be operated by pulling the load. It's equipped with tapered roller bearings for smooth movement. The drive system includes a planetary gear, chain drive, and bevel gear. To use the crank, it must be pulled down. I've also designed a simple brake system that operates through mass forces and features four pistons per disc by Brembo. The transported car can be secured using six lifting eyes, with a pulling capacity of 1120 kilograms each. The minimum ground height is 20 mm, while the maximum is around 140 mm.
