I am building a large ski resort with multiple fixed grip chairlifts and one detachable I am having problems with the fixed grip and I haven't done more than the frame on the detachable. the problems I am having with the fixed grip are simple, but I cannot figure out how to fix them. the chairs jam up a lot and the rope derails easily, both of which can damage the entire lift. on the detachable I need a small grip that can detach and reattach at the terminal, but flow easily over support and hold down sheaves. I am trying not to spent too much, but I want all of the lifts to work right. I am using power functions XL motors to power them. -
While skiing I had the idea to reproduce an entire detachable ropeway just with LEGO-Technic-Bricks. After 400 hours of developing, testing and programming the model was built from scratch without any construction plans. This ropeway is an improved version of my first ropeway 2 years ago ;) This model-ropeway works just as its real brother. The eight gondolas are detached in the stations and slowed down to let passengers board easily. But not just the cable-clamp-mechanism is realized like in real ropeways but also the rope tensioner. This mechanism keeps the haul-rope always tensioned by the information of the sensors. Other sensors supervise the distance between the gondolas and adjust it when needed by slowing down a specific motor. Also the haul-rope is monitored by sensors. If the rope falls out of a deflection pulley the whole system performs an emergency-stop. The entire model and even the whole control system with sensors and processors consists of usual LEGO-parts and is driven by 16 motors in total. Along with about 300 gears and 1‘000 chain-links, 10'000 parts were needed. Pictures of the building process can be found on Facebook Next year I plan to build an intermediate station with another 6’000 parts. The whole ropeway-model then will be powered by 30 motors, 4 Mindstorms-Computers, 15meters of technic-chain-links and about 500 gears.
